DANGER
Because diesel fuel 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 diesel fuel before start-
ing the engine. Store fuel in a clean, safety- -ap-
proved container and keep cap in place. Use die-
sel 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 Operator's Manual. Check lines for dete-
rioration, damage, leaks or loose connections. Replace
hoses, clamps and connections as necessary.

mended in the Operator's Manual. Also, empty and
clean the fuel tank if the fuel system becomes contami-
nated or if the machine is to be stored for an extended
period.
To clean fuel tank, flush tank out with clean diesel fuel.
Make sure tank is free of contaminates and debris.
