The operator should conduct a pre-start visual check with the key off and then perform an operational check with the engine running. The forklift should not be placed in service if the examinations show that the vehicle may not be safe to operate.
Before starting your vehicle, conduct a pre-operation (or pre-start) inspection that checks a variety of items, including but not limited to:
Liquid Propane Forklifts
Note: Always use personal protective equipment such as a face shield, rubber apron, and rubber gloves when checking electrolytes.
