WARNING
The use of Personal Protective Equipment (PPE) is required when using or handling hazardous
materials associated with operating and maintaining equipment (jet fuel, hydraulic luid, brake
luid, ethylene glycol, cleaning solvents, compressed air, and engine/axle oil). Failure to use
PPE when handling these materials could result in injury or death.
Fuel vapors create ire and explosion hazards that will result in severe personal injury or
death. Do not allow any open lame, smoking materials, or other potential igniter near fuel
or the fuel system.
Do not mix gasoline or alcohol with diesel fuel. This mixture can cause an explosion. Try not to
spill fuel during refueling; if fuel should spill, wipe it off at once or it may cause a ire. Always
keep spilled fuel and lubricants away from engine.
When servicing any part of the fuel system, ensure the engine is shut down and the unit s
batteries are disconnected.
Do not smoke when working around the battery or when refueling.
When servicing the fuel system ensure vehicle is in a well ventilated work space.
CAUTION
After removing fuel hoses or lines, plug them at both ends with protective caps to prevent
contamination from entering. Contamination in fuel hoses may cause fuel injector pump
malfunctions.
