14. INSPECTION AND MAINTENANCE
Only trained and certified personnel may change LPG tanks.
Turn ignition switch to the OFF position.
Change LPG tanks in designated and well ventilated area approved for this operation.
Check LPG tank and lines for fuel leaks.
Ensure no sparks, flame or ignition sources are present.
Once the full tank is in place, ensure it is mounted correctly and securely. Check all connections.
Do not attempt to start the truck until all LPG odor is gone.
If the truck is hard to start, contact a certified mechanic to repair the problem. Tag the truck "Out of
Service" until properly repaired.
When the battery is charged, hydrogen gas is generated and the battery is heated by the chemical
change. To prevent the danger of gas explosion, always do as follows:
1.
Carry out the charging operation in a well-ventilated place.
2.
Do not smoke or allow any flame.
3.
Start the charging operation when the temperature of the battery electrolyte is below 95° F (35° C). If
the electrolyte temperature goes above 122° F (50° C) during the charging operation, wait for it to go
down below 95° F (35° C) before starting charging operation again.
When using a battery charger to charge the battery, take the battery caps off.
ALWAYS wear safety glasses or goggles when starting the lift truck with booster (jumper) cables.
When starting using the battery of another lift truck, do not allow the two lift trucks to touch.
Stop the engine before connecting the cables.
Be extremely careful not to let the cables get caught in the fan or fan belt.
Connect the batteries in parallel; positive-to-positive and negative-to-negative. NEVER connect positive to
negative.
DO NOT short-circuit the starter terminals to start a forklift truck.
Do not push the lift truck to start the engine. There is danger that the lift truck may suddenly start and operate
unexpectedly.
