Description on Slow-blow Fuse
In case of heavy current, the slow-blow fuse will
protect the elements and allow the operation until the
circuit is broken due to overload. In case of low
current, the fuse will be melted slowly and all the
inconvenience resulted from changing fuse frequently
will be solved.

Replacement of fuse
1. Remove the screw (9) for fixing fuse holder to
bracket (8).
2. Press the clip (3) and open the cover (2).
3. Use a screwdriver to open the side cover (6 and 7).
Caution: Check the opened terminal.
4. Remove the screw (4) out of the connector (5) and
take off the fuse (1).
5. Install a new fuse.
6. Assemble in a reverse order.

When the AUTO/MANUAL switch is at MANUAL
position, the resistor box will have the current
reduced and accordingly the proportional
solenoid valve has the engine rated output power
reduced by 85%.
