Chemical Hazards
Exhaust Fumes
• DO NOT operate machine in an enclosed area without proper ventilation.
• DO NOT operate the machine in hazardous environments unless approved for
that purpose by JLG and site owner. Sparks from the electrical system and the
engine exhaust can cause an explosion.
• If spark arrestors are required, ensure they are in place and in good working
order.
Flammable Fuel
• DO NOT fill the fuel tank or service the fuel system near an open flame, sparks
or smoking materials. Engine fuel is flammable and can cause a fire and/or
explosion.
Hydraulic Fluid
• DO NOT attempt to repair or tighten any hydraulic hoses or fittings while the
engine is running or when the hydraulic system is under pressure.
• Stop engine and relieve trapped pressure. Fluid in the hydraulic system is under
enough pressure that it can penetrate the skin.
• DO NOT use your hand to check for leaks. Use a piece of cardboard or paper to
search for leaks. Wear gloves to protect hands from spraying fluid.
