Please use the following cleaning procedure for routine
maintenance:
1. Turn the power key to OFF position.
2. Remove power by disconnecting the battery.
3. Discharge the capacitors in the controller by connecting
a load (such as a contactor coil or a horn) across the
controller’s B+ and B- terminals.
4. Remove any dirt or corrosion from the connector areas.
The controller should be wiped clean with moist rag. Dry
it before reconnecting the battery. The controller should
not be subjected to pressured water ow from either a
standard hose or a power washer.
5. Make sure the connections are tight, but do not
over-tighten them.
NOTES: All above checks shall be performed under power o.
Above checks shall be carried out once every 3 months; after
the power key turns o, the wave-lter capacitor in the con-
troller unit shall keep discharging for a few minutes more; don’t
wash the electrical parts with water. It is allowed to remove
dust with a brush or high–pressure air.
7.5 Maintenance of Brake System

travel shouldn’t exceed 2/3 of the full free pedal travel.
2. The clearance for the brake plate is self-adjusted. Under
a force of around 20kgs, the parking brake handle should
be xed in one gear from 5 to 10 ratchet. When the brake
handle is released completely, the brake function will
stop.
3. Inspect and change brake shoe, add lubrication into the
brake bearing periodically.
