DANGER
Because diesel fuel is highly flammable, use
caution when storing or handling it. Do not
smoke while filling the fuel tank. Do not fill fuel
tank while engine is running, hot or when ma-
chine is in an enclosed area. Always fill fuel tank
outside and wipe up any spilled diesel fuel be-
fore starting the engine. Store fuel in a clean,
safety−approved container and keep cap in
place. Use diesel fuel for the engine only; not for
any other purpose.
Check Fuel Lines and Connections
Check fuel lines and connections periodically as recom-
mended in the Traction Unit Operator’s Manual. Check
lines for deterioration, damage, leaking or loose con-
nections. Replace hoses, clamps and connections as
necessary.
Drain and Clean Fuel Tank
Drain and clean the fuel tank periodically as recom-
mended in the Traction Unit Operator’s Manual. Also,
drain and clean the fuel tank if the fuel system becomes
contaminated or if the machine is to be stored for an ex-
tended period.
To clean fuel tank, flush tank out with clean diesel fuel.
Make sure tank is free of contaminates and debris.
