FUEL SYSTEM (Fig. 25)
Fuel Tank
Drain and clean fuel tank every 800 hours of operation
or yearly, whichever comes first. Also, drain and clean
tank if fuel system becomes contaminated or if
machine is to be stored for an extended period. Use
clean fuel to flush out the tank.
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 machine is in an
enclosed area. Always fill fuel tank out
side and wipe up any spilled diesel 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.
Fuel Lines and Connections
Check lines and connections every 400 hours or yearly,
whichever comes first. Inspect for deterioration,
damage, or loose connections.
Draining Fuel Filter / Water Separator
Drain water or other contaminants from fuel filter /
