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 Operator’s Manual. Check fuel lines for
deterioration, damage or leaking connections. Replace
hoses, clamps and connections as necessary.
Drain and Clean Fuel Tank
Drain and clean the fuel tank periodically as recom-
mended in the 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 extended period.
To clean fuel tank, flush tank out with clean solvent.
Make sure tank is free of contaminates and debris.
