6. Refit the inspection cover and
ensure the latches are engaged.
7. Carefully stow the special latch key.
Figure 2-1 Cleaning the suction fan
2.3 How the machine
works
The machine works due to the air moving
through it. The following scheme shows the
flow of air through the machine. The two
front brushes sweep dirt, trash and debris
into the center of the machine, so that the
airflow can pick these up and deposit them
into the hopper
The air and debris mixture to swirl in a
cyclonic action inside the hopper in order to
cause the debris to separate out, falling into
the lower part of the hopper and allowing
the air to return to atmosphere through
exits in the top of the hopper. There are 3
separating actions in the hopper:
•
•
•
The initial entry cyclonic action which
is aided by swirl plates in the rear of
the hopper;
Screens in the hopper which prevent
light material such ad dry leaves and
paper from escaping;
The final cyclone spinners located in
the top of the hopper, which
separate out small dust particles.
As long as the airflow is maintained, the
machine will work correctly. If the machine
does not pick up or leaves a trail, this
means the air is not flowing correctly
through the machine. Always bear in mind
this notion of airflow.

2.5 Setting the
brush angle
This operation usually only requires to be
requires to be carried out when the
machine is installed. The requirement is to
set the angle of the brushes so that they
sweep the debris into the central part of the
machine, where the airflow will pick it up.
To do so, the brushes need to be tilted so
as to touch the ground as shown on figure
2-4.

In light duty conditions (paper litter), very
little, or no flap vibration is required.
In heavy duty conditions (wet sand), rather
more flap vibration is required.
To set the flap vibration:
•
Select sweep mode, engage
FORWARD drive and set the FAN
speed to 2200rpm. Commence
sweeping.
•
From inside the cab you should just
be able to hear the flap vibrating.
•
If the flap requires adjustment,
STOP the machine, apply the
PARKING brake, put the DRIVE
lever in NEUTRAL. Go to the front of
the machine and turn the black
adjuster knob (try one complete turn
per adjustment), CLOCKWISE to
increase vibration activity and ANTICLOCKWISE to decrease.
•
Re-check for satisfactory sweeping
performance and re-adjust as
necessary.
•
Ensure that the adjuster is locked
after setting.

Chapter 3 Getting Started
If the machine is set correctly and has been cleaned in the manner prescribed, you will
continued performance for the whole of the shift.
The most common problem experienced by machine operators is that the machine does not
pick up, and leaves a trail. Usually, this means either the machine has not been set correctly
or there is an airflow restriction (please see 2.3 – How the machine works).
If you experience problems with the machine not picking up debris/trash, refer
to section 7 – Fault Finding.
3.1 Adjusting the
driving controls
Adjust the backrest with the upper lever at
the right hand side of the seat. As shown in
figure 3-2.
1. Your seat is adjustable.
Move the seat forward or backward using
the lever on the seat on the right hand side.
As shown in figure 3-1
To adjust the tilt (thigh support adjustment)
use the lower lever at the right hand side of
the seat.
Adjust the suspension setting of the seat by
adjusting the lever below the seat, in the
middle. Pull out knob to obtain more
leverage and move towards left for
increasing driver weight. As shown in figure

1. Transit mode is used to drive the
machine at high speed (from the storage
depot to the sweeping site), up to 32 km/h
(20 mph). The brushes and nozzle are
raised when using this mode. Please note
the machine will not travel at high speed
until the front wheels have tracked out,
thereby increasing the overall vehicle
stability. The operation takes about 10
seconds, and will be performed
automatically as the machine starts gaining
speed. For short distance traveling from
one sweeping zone to another, it may be
more efficient to use Brush lift mode (see 3
below).
2. Sweep mode (work 1) only enables lowspeed drive, up to 15 km/h (9 mph). The
front wheels are tracked-in to enable
sweeping access to narrow alleyways. The
brushes and suction nozzle are
automatically deployed when sweep mode
is selected.
3. Brush lift mode (work 2) is used to
travel at low speed over short distances
when not sweeping. Indeed, it is sometimes
not good use of time to use transit mode for
short distance travel, as the front wheels
have to track out and then back in. The
Brush lift mode is similar to Sweep mode
(same max. speed) except the brushes and
nozzle are raised and the limited slip
differential system is engaged.
It is important to check that the front
wheels are fully tracked in before
sweeping close to a wall or curb. If not
fully tracked in tire damage may result.
3.3.2 Speed control
(accelerator) pedal
The pedal is located right of the center on
the floor. The same pedal is used for both
forward and reverse motion.
Pressing the pedal gently will cause the
machine to move forward or backward
depending on the setting of the
Forward/Reverse lever. If the lever is set to
Neutral, then pressing the accelerator will
simply speed up the engine.
Figure 3-10 Accelerator pedal
3.3.3 Braking
Releasing the accelerator pedal will cause
the machine to slow down by automatically
applying hydraulic braking.
The brake pedal operates on the rear
brakes.
The handbrake also operates on the rear
brakes, and should always be applied when
leaving the cab. A buzzer sounds if
Forward or Reverse is selected with the
handbrake applied to remind you to release
it.
3.3.4 Wheel tracking
The 636 is equipped with a variable track
width front axle. This enables the machine
to operate in narrow passageways (1.1m
machine width) during low speed (15 km/h
max.) Sweep (Work) mode.
In high speed (32 km/h max.) Transit mode,
the front wheel track width is increased to
1.33m over wheels. This increases
machine stability at high speed.
Tracking (changing the front wheel track
width) is automatically controlled by the
MDM electronic control system.

(if not already tracked out) as you
are gaining speed, provided that you
are in Transit mode.
(For switch location see Section 3.2)
1. Engage Neutral
2. Get into transit mode
In Transit mode, you should drive
the machine almost as you would
drive a car with automatic
transmission. Remember the
machine has features such as a
seatbelt, a rear-view camera display
(where fitted – same use as a rear
view mirror) and indicators

10. Stopping the engine. Prior to
switching off the engine directly from
Sweep mode (high engine speed),
first engage Transit mode and idle
the engine for 3 minutes before
switching off, in order to cool the
turbo.
3.3.8 Going up and down
pavement curbs
Never go up or down a pavement curb with
the brushes and nozzle down (always use
Brush Lift mode).
Never drive up and down pavement curbs
at too high a speed or too oblique an angle.
In exceptional circumstances when
mounting curb’s, one wheel may lose
traction due to uneven weight distribution.
In Brush Lift mode a limited slip differential
system is automatically engaged to prevent
the vehicle from coming to a stop due to
that wheel spinning.

3.4.2 Water system
The machine is equipped with 3 dust
suppression water spray systems. The
water system deploys only when you are in
Sweep mode and Forward is selected.
Figure 3-17 Curb climbing
The dust suppression is supplied from
water tanks via a manifold, mesh filter and
an electric pump which are located at the
rear of the machine and can be accessed
by swinging open the rear water tank.
Cloudmaker
Figure 3-18 Curb climbing
3.3.9 Brush/Nozzle –
Raising in Transit Mode
After the machine has been parked up for
some time in Transit mode with the wheels
tracked out, the brushes and/or nozzle may
drop. To raise these before driving off, carry
out the following operation.
Start the engine and allow it to warm up,
move the mode switch into Sweep mode,
move the Forward/Neutral/Reverse joystick
into Forward and then into Neutral. This will
cause the IQAN to apply Brush/Nozzle Lift
for 4 s. Return the mode switch to transit.
3.4 Using the sweep
mode
A high-speed rotary atomizer, which
produces a cloud of very fine droplets in
front of the suction nozzle. These fine
droplets are very effective for suppressing
fine dust particles.
When sweep mode is selected the rotary
atomizer will descend with the Nozzle into
its working position and it will start rotating.
When the water rotary control switch is
moved to Position 1 (Sun symbol), a cloud
of atomized water will appear at the
Cloudmaker rotating spray head. In
Positions 0 (Heavy Rain symbol) and 2
(Light Rain symbol), the water supply to the
Cloudmaker water supply is switched off
(via a solenoid valve), but the Cloudmaker
motor continues to rotate in order to keep
the sintered spray head clean.
3.4.1 Switching to sweep
mode
With the engine running, use the top left
switch on the switch column to switch to
Sweep mode (switch in middle position.

Brush Spray Jets
System Protection
When the water rotary switch is in Positions
1 or 2, you can set the amount of water
supplied to the brushes by turning this
control needle valve (to your left).
If the water tank runs dry a sensing switch
will turn off the water pump.
If the Cloudmaker motor speed drops below
50% the MMU system will switch off
Cloudmaker and display an instruction to
switch off the water supply to Cloudmaker
(by turning the rotary control switch to
position 0 or 2). Inform your Supervisor.
Cloudmaker may be damaged if it is
supplied with water when it is not rotating.
Cloudmaker must be rotating before it is
fed water.
When using the brushes in a dry area,
make sure you use the front water jets.
Figure 3-21 Control valve
The jet can be cleaned by removing the jet
holder (half turn).
Suction Pipe Spray Jet
With spray water inside the suction pipe to
reduce mud build up in “sticky” conditions
when the rotary control switch is set to
Positions 1 and 2.
The spray jet is located on the right hand
side of the suction pipe just above the
suction hose. It can only be accessed for
maintenance by tilting the cab.
The following table shows the
recommended water control switch
positions for various sweeping conditions,
and the subsequent actions.
Hopper Drain
Provided the hopper drain switch (located
above the right hand switch column) is in
the ON position (switch down & lit), the
hopper drain will automatically open when
Sweep mode is engaged. The drain will
close when the suction stops.
Figure 3-23 Hopper drain switch
In certain sweeping conditions e.g. wet
weather conditions whilst sweeping in a
sensitive Pedestrianised area, it may be
required to close the drain even with the
suction fan operating. This can be achieved
by switching OFF the drain switch. In this
situation, in very wet conditions, water will
build up very quickly inside the hopper and
the machine may have to be taken to a
suitable discharge area.
If the water system does not work, check
the water tank level at the back of the
vehicle behind the hopper skirt (refer to
fault finding section if the water system still
does not work).

Filling the Water Tank(s)
Ensure water tank is in the stowed position.
Undo the cap on the top of the rear water
tank and insert a hose of 30mm (1.2 in.)
maximum outside diameter to allow
sufficient space for venting. Do not use too
high a flow or the water may enter the tank
faster than the air can be vented causing
damage to the tank.
Figure 3-24 Water tank level
The water mesh filter, located under the rear
water tank, must be cleaned regularly.
Always drain all water from the tank
when conditions are frosty.
To swing out the water tank, undo the
safety chain and then use the lever shown
on figure 3-23.
Sweeping on uneven Ground
When sweeping on exceptionally uneven
ground, one wheel may spin due to uneven
weight distribution. If this happens, engage
Brush Lift mode, in which case a limited slip
differential system will automatically be
engaged preventing wheel slip. Move to
even ground and re-engage Sweep mode.
3.4.3 Setting the brush
height
In order to sweep correctly, the brush
height needs to be set correctly. You do not
need to set the brush height each time you
engage sweep mode, but remember the
brushes require adjusting as they wear.

3.4.4 Moving the brushes
sideways
There are two small joysticks on the control
arm. Each of them controls one brush. You
may use this feature when driving next to a
wall to clean as close to the wall as
needed. The swept track can vary from
1200mm (47.2 in) to 1800mm (70.9 in).
Figure 3-29 Impeller/brush rotary controls
Use the right hand side control to set the
brush rotation speed. The brush speed
should be set to the minimum speed
necessary to provide clean sweeping for
the forward speed being used.
The maximum brush rotational speed is
130RPM +/- 10%.
Use the left hand side control to set the
impeller rotation speed (the IQAN displays
the current speed).
The vacuum fan impeller speed should be
set to below 2400 rpm for normal sweeping.
Figure 3-28 Brush joysticks
The widest swept track available is
sometimes too wide for the sweeping
conditions. If debris/trash tends too be left
on the sides of the sweep path, try
narrowing the swept path. (Also, see
section 7 – Faultfinding).
3.4.5 Setting
impeller/brush speed
On the right hand side switch column are
the two rotary controls, shown in figure 329.
The speed can be set to above 2400 rpm
(boost) for a short time (up to 5 minutes).
When in boost the machine management
unit (MMU) will display a countdown bar
graph. If the speed is not reduced to under
2400 rpm within 5 minutes, the MMU will
shut off the fan and a buzzer will sound. To
reset the MMU fan speed limiting system
the machine must be stopped and the
Forward/Neutral/Reverse switch moved to
the Neutral position. The machine can then
be re-started and the impeller speed
reduced to below 2400 rpm.
To reset the MMU fan boost speed limiter
within a boost cycle, reduce the fan speed
below 2400rpm for at least 30 seconds or
the machine must be stopped and neutral
selected for 5 seconds on the
Forward/Neutral/Reverse lever (as above).

The MMU will restrict boost to a maximum
of 5 boost periods per hour. After 5 boost
periods, the fan speed will be limited for the
remaining part of the hour to approximately
2300rpm.
To turn the impeller on/off while sweeping,
use the appropriate column switch.

The hopper contains a special filtration
cartridge that is located inside the hopper,
laid along its floor. The cartridge is
protected by a guard and can be withdrawn
from the side of the hopper for cleaning.
When the extra water in the hopper is used

5.3 Street Washer
Model – 636SW
Introduction
The Street Washer 636SW is a dual
function machine, which can perform both
functions of Sweeping and Street Washing.
The machine cannot Sweep and Street
Wash simultaneously. However changing
over from one function to the other is
relatively quick does not involve the use of
tools.
The street washer comprises a highpressure reciprocating piston water pump
driven by a hydraulic motor. The pump
feeds high-pressure water to a folding
boom spray bar located at the front of the
machine. Operating one of the brush
control joysticks can hydraulically slew this
spray bar from side to side. The joystick
changes function when Street Wash is
selected. The spray bar is hinged in the
center and will fold to avoid damage if it
accidentally contacts an obstacle when
moving in the forward direction. The spray
bar can be folded up and stowed out of the
way in front of the cab windscreen when
the machine is being used as a sweeper.
Preparing to Street Wash
The hopper must be emptied (tip the
hopper) and thoroughly washed out. Check
that the hopper filter is clean by undoing the
toggle clamps on the right hand side of the
hopper and withdrawing the cartridge.
Clean the textile sleeve. Undo the screw
cap and withdraw the stainless steel mesh
filter. Clean the mesh filter if necessary.
Fold down the hopper fan duct sealing
diaphragm (to prevent water surging out of
the hopper into the suction fan casing
during braking).

The sprays on the spray bar will start
spraying – it may take 1 or 2 minutes to
obtain a full spray pattern with the fan
sprays meeting. If full spray is not available
within 2 minutes, switch off the Street
Washer and check for blockages and
correct valve pressure.
DO NOT run the street washer pump fir
periods in excess of 2 minutes with no
water passing through the pump, as
permanent damage to the pump will result.
Use the left hand Brush control joystick on
the control arm to slew the spray bar from
side to side. Operating the spray bar at
angle will wash debris to one side of the
washed path.
The spray bar fan sprays should just meet
at the ground. If there are gaps between
the sprays, raise the spray bar using the
rotary height adjuster at the rear of the
spray bar suspension bracket.
The water in the hopper will provide about
25 minutes of street washing. When the
hopper becomes empty, this will be
indicated by the sprays becoming
intermittent. If the street washing task is not
completed an extra 12 or 8 minutes of
street washing can be obtained by using
the water in the dust suppression water
tanks (there are 2 of these connected
together). The water is accessed by
swinging open the rear water tank and
turning the 3-way valve to “Water Tank”.
Close the rear water tank. The street
washer pump will not draw water from the
dust suppression water tanks.
DO NOT run the street washer pump for
periods of 2 minutes with no water
passing through the pump

Ensure the hopper is empty water. If a
significant amount of water (more than 50
or 60mm) still remains in the hopper, drain
it out by deploying the “wet weather”
drogue on the front left hand side of the
hopper.
Tip the hopper and fold up and stow the fan
ducting seal diaphragm.
Ensure that the 3-way valve (above the
suspension spring) is set to “WATER
TANK” to prevent dirty water from the
hopper accidentally entering the dust
suppression water circuit.

5.4 Air Conditioning
(Optional)
The Air Conditioning (AC) operates via an
engine driven compressor which is
equipped with an electro magnetic
engagement clutch.
The air is cooled in an evaporative located
behind the drivers headrest. A circulation
fan passes air through the evaporator and
along a roof duct on the right hand roof rail.
The air exits at 2 ducts in this area. The
ducts have directional grilles which can be
altered to direct the flow if air. The
Figure 5-13 Air conditioning vents
The excess heat is rejected on a condenser
heat exchanger mounted on the outside,
front area of the roof. Electrically operated
twin fans circulate cooling through the
condenser.
Prior to switching on the AC, ensure that
the Heater Control on the left hand side of
the drivers seat is turned off. The heater air
circulation fan will automatically be
switched off when the AC is switched on.
The AC is switched on via the AC switch
(snowflake symbol) on the right hand switch
column of the cab. It has 2 positions. Use
position 1 for normal cooling and position 2
for boost. The engine must be running. The
window and the roof latch should be closed
when the AC is operating to prevent all
cooled air from escaping from the cab and
being replaced with hot air from outside. In
hot, humid conditions water will condense
on the evaporator surface. The water
escapes to the outside of the cab via a
drain duct. Water dripping from this duct
under the cab is quite normal.

5.5 Automatic
Greasing (Optional)
Introduction
The Interlube AC lubrication system has
been specifically designed to provide
reliable and virtually maintenance free
service. The AC lubricator and its
accessories are ruggedly constructed for
faultless operation in the most demanding
applications.
The AC system is wired via a relay to the
vehicle “SWEEP” mode system. The
lubrication system only operates when the
machine is in SWEEP mode and with the
Forward/Neutral/Reverse switch in
Forward. In operation the cam rotates
operating each pumping unit in turn
injecting a measured amount of lubricant
into each supply line. During operation a
green indicator light shows on the reservoir
top cover. To check for satisfactory
operation, press the TEST button on top of
the unit. This will start the motor and the
paddle can be seen to rotate in the
reservoir. It will rotate once in about 3
minutes before re-setting to its normal 1
rotation every 12 minute period.
A 2A inline fuse is used.
The pump cycle time is 12 minutes and is
not adjustable.
Maintenance
Figure 5-15 Automatic greasing location
In common with other electro mechanical
devices however, proper operation
procedures must be carefully observed.
Operation
The AC lubricating system comprises an
electrically operated lubricator and a loom
of tubing connecting each chassis bearing
to its own respective pumping unit. The
lubricator consists of a 1.25 liter reservoir,
housing the electronic control, electric
motor and drive. The top cover incorporates
a filler cap for semi-fluid grease. Housed in
the reservoir is a twin-blade impeller
designed to draw grease evenly into the
pumping chamber and give a full visual
indication of cam rotation. Attached to the
reservoir is a carcass ring, which houses
the cams and pumping units (red
0.010cc/shot, green 0.015cc/shot, yellow
0.025cc/shot, blue 0.040cc/shot, silver
0.060cc/shot and black 0.100cc/shot). This
machine is fitted with 34, blue
(0.040cc/shot) pumping units.
As an owner of an Interlube AC system the
only maintenance you should find
necessary is to periodically check the
reservoir lubricant level, topping up with the
recommended lubricant as necessary, and
occasionally checking the condition of loom
connections.
At all times observe the following for fault
free operation.
•
•
•
Use semi-fluid grease specification
NGLI 000EP.
Ensure stored lubricant is kept clean
at all times.
After filling the reservoir make sure
the filler cap is secured.
If the system should fail to operate
satisfactorily the following diagnostic and
remedial advice will help to identify and
correct any fault.

In order to fit these options, the machine
must have special preparations fitted at the
factory.
The Winter Equipment must be fitted and
removed from the machine by a suitably
qualified mechanic, who will ensure that the
control system is correctly activated (and
de-activated on removal)
The Front Snowbrush is powered by the
Suction Fan hydraulic system. A selector
switch and solenoid valve(s) re-directs the
flow of oil from the Suction Fan to the
Snowbrush. Note it is essential that the
Snowbrush switch is NOT selected when
the Snowbrush hoses are disconnected
from the quick-connect couplings as this
will direct the oil to a dead end causing the
pressure relief valve to operate
continuously. This will lead to the
overheating of the oil and possible damage
to the hydraulic pump. The fitting mechanic,
on removal of the equipment, must deactivate the selector switch system, or, on
earlier machines de-activate the solenoids
by inserting the dummy loom.
The rear Gritter is powered by the Front
Sidebrush system. A selector switch and
solenoid valve re-directs the flow of oil from
the Sidebrushes to the Gritter. Again it is
essential that the Gritter switch is NOT
selected when the Gritter is not on the
vehicle or dead-heading of the circuit will
occur. The fitting mechanic, on removal of
the equipment, must de-activate the
selector switch system, or, on earlier
machines de-activate the solenoids by
inserting the dummy loom.
The Snowplough Blades can be slewed
using the Sidebrush slewing system (The
joysticks on the control pod). The right hand
system is used for the Straight blade and
the right hand and left hand systems are
used for the V Blade.
Operation
The equipment will only operate when the
machine is in Sweep (Work) Mode (See
section 3.4) with the
Forward/Neutral/Reverse selector in
Forward.
To operate the Snowbrush, operate switch
(Item 1) and control speed with Fan Speed

10.1 Rescue
In case of an emergency or transmission
failure it is preferable to rescue the machine
with an uplifting rescue vehicle.
Once the rescue valve on the inner side of
the transmission pump has been turned
through 90° the machine may be winched
onto the rescue vehicle.
The machine may be towed at slow speed
(5 mph maximum) for short distances (2
miles maximum) using a solid tow bar.
Again the rescue valve must be opened.
Note: whilst being towed with the engine
stopped, power steering will not be
available. Manual steering will be available
provided the steering hoses are intact.
In order to access the engine compartment
when the engine won’t start, use the
manual hopper tilt system. There is a
manual pump located on the right hand
side of the machine. The pump handle is
stowed inside the right hand side access
cover. Insert the handle in the pump and
start pumping, the hopper will tilt. If it is
necessary to lower the hopper manually,
there is a needle valve in front of the pump,
which can be released. Be especially
careful when lowering the hopper by
this method, ensuring that all personnel
are clear of the hopper lowering zone
and that the casing access door is
closed. Remember to close this valve
after use or the power tilt system will not
operate.
It is very important that the following
actions are carried out before any welding
takes place on the 636.
3. Disconnect the positive and negative
battery terminals.
4. Disconnect the engine speed sensor
at the left hand side, on the bell
housing.
5. Disconnect the vehicle speed sensor
at the left hand rear wheel motor.
6. Disconnect the vacuum fan sensor
(fan casing).
7. Disconnect every connector on the
main and auxiliary hydraulic blocks,
left and right hand respectively.
8. Disconnect the earth post (right
hand) next to the electrical box
(gray) under the cab floor.
Failure to carry out these instructions will
damage the machines electronic control
system.
DO NOT tow the machine at
speeds of over 5 mph or for a
distance greater than 2 miles.
10.2 Transportation
Vehicle unladen weight 1950kg.
When transporting the machine, it shall be
secured by means of suitable straps as
follows.
Front Wheels:
One strap per wheel to
a REARWARD lashing
point.
Rear Wheels:
One strap per wheel to
a FORWARD lashing
point.
Front of Body:
Two straps from towing
eye to FORWARD and
OUTWARDS lashing
points.
