Service Checks
Check Engine Air Intake Precleaner
1.
The engine is equipped with a precleaner. Dust, insects,
rainwater etc., can be present in the air. The precleaner
collects this material and discharges it. This prevents
material from being drawn into air cleaner. The precleaner
does not need periodic replacement.
Drain Water From Hydraulic Oil Tank
1.
Position machine on firm, level ground. Lower boom and
position bucket on ground. Shut down engine.
2.
Position a container under hydraulic tank drain plug. Open
tank breather cap (See Figure 19 on page 4-24). Loosen
drain valve at bottom of tank (Figure 51). Allow all water
and sediment to drain out. Tighten drain valve.
NOTE:
Dispose of drained fluids according to local
regulations.
Figure 50
WARNING
Be certain that hydraulic oil has cooled before draining
water and sediment. Hot oil could splash and cause burns.
The hydraulic tank is pressurized. Unscrew the cap of
breather on the top of hydraulic tank to allow pressurized
air to vent. After pressure has been released, it is safe to
remove either the fill cap or service covers.
