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 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 Operator’s Manual. Check lines for dete-
rioration, damage, leaks or loose connections. Replace
hoses, clamps and connections as necessary.
Empty and Clean Fuel Tank
Empty and clean the fuel tank if the fuel system be-
comes 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.
Fuel Tank Removal (Fig. 3)

gage parking brake and remove key from the ignition
switch.
2. Use a fuel transfer pump to remove fuel from the fuel
tank and into a suitable container.
3. Remove the fuel tank cover. For machines with an
evaporative control system, remove the carbon canister
from the fuel tank cover/canister bracket if necessary.
4. Disconnect the fuel pump/level sender form the ma-
chine wire harness (2 connectors).
CAUTION
Fuel in supply line may be under pressure. Cov-
er supply hose barb fitting with rag while discon-
necting to absorb any fuel leakage.

hose through machine as recorded during removal.
Make sure that clearance exists between fuel hose and
machine components along full length of hoses.
