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 cleaning or replacement.
DRAIN WATER FROM HYDRAULIC OIL TANK
Be certain that hydraulic oil has cooled before draining water and sediment. Hot oil could splash
and cause burns.
The hydraulic tank is pressurized. Press button in center of breather to allow pressurized air to
vent. After pressure has been released, it is safe to remove either the fill cap or service covers.
1. Position machine on firm, level ground.
Lower boom and position bucket on
ground. Shut down engine.
2. Position a container under hydraulic
reservoir drain
breather cap (See Figure 13 on page 4-
13). Loosen drain valve from bottom of
reservoir (Figure 50). Allow all water and
sediment to drain out. Tighten drain valve.
NOTE: Dispose
according to local regulations.
CLEAN AIR CLEANER
CAUTION!
Never remove air cleaner element while
engine is running. This will allow dirt to be
sucked into engine and cause serious
engine damage. Always turn engine "OFF"
before servicing air cleaner.
