DANGER
Because gasoline is highly flammable, use cau-
tion 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 machine is
in an enclosed area. Always fill fuel tank outside
and wipe up any spilled fuel before starting the
engine. Store fuel in a clean, safety−approved
container and keep cap in place. Use gasoline
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 solvent.
Make sure tank is free of contaminates and debris.
