3. Every 1,000 hours operation, or yearly, replace the
engine fuel filter (Fig. 38)—left front side of
engine—and drain water from the fuel tank. Apply
clean fuel oil to the filter O-ring. Use hands only to
install and tighten the filter.
4. If the fuel system becomes contaminated or the
machine is to be stored for an extended period,
locate the drain at the bottom of the fuel tank and
drain and clean the tank. Flush the tank with clean
fuel oil.

IMPORTANT: Following the maintenance steps listed
above will, under normal conditions, keep the system
trouble-free. However, if the indicator light on the
control panel and audible warning signal activate
during operation, the engine should be stopped and the
fuel system serviced before operation is resumed. This
can prevent serious engine damage from occurring.
ENGINE COOLING SYSTEM
The cooling system holds approximately 14.7 L of a 50/50
solution of ethylene glycol anti-freeze and water. To
properly maintain the system, use the following procedures:
1. Check coolant level each day before starting the
engine; refer to Check Cooling System in Before
Operating section.
2. Each day after operation, clean debris from the
radiator grille. Clean more frequently in dusty and
dirty conditions.
A. Move the seat forward as far as possible.
B. Remove the upper and lower grille assemblies
(Fig. 39).
C. Use compressed air to clean the grilles and
remove debris from the grille mounting areas.
D. Install grilles after cleaning, lower and lock the
seat in position.

3. Every 100 hours of operation, clean the radiator and
hydraulic cooler fins. Clean more frequently in
dusty and dirty conditions.
Maintenance
32
Check coolant level before the engine has been
started because the coolant system will not be
pressurized. When the engine is hot and the radiator
cap removed, hot pressurized coolant can escape and
cause burns. If engine coolant is hot, slowly and
carefully remove radiator cap.
