Servicing the Fuel System
Fuel Tank
Drain and clean the fuel tank every 2 years. Also, drain and
clean the tank if the fuel system becomes contaminated or
if the machine will be stored for an extended period of
time. Use clean fuel to flush out the tank.
Fuel Lines and Connections
Check the fuel lines and connections every 400 hours or
yearly, whichever comes first. Inspect them for
deterioration, damage, or loose connections.
Water Separator
Drain water or other contaminants from the water separator
(Fig. 40) daily.
1. Place a clean container under the fuel filter.
2. Loosen the drain plug on the bottom of the filter
canister (Fig. 40). Tighten the plug after draining.
