MAINTENANCE
EVERY 4000 HOURS
REPLACING THE HYDRAULIC OIL AND
CLEANING THE SUCTION STRAINER
• Stop the engine and allow each part of
the machine to cool down before
performing maintenance.
· The engine, the hydraulic system and
many other parts of the machine are
hot immediately after the engine is
stopped. Touching these parts will
cause burns.
· The hydraulic oil is also hot and under
high pressure immediately after the
engine is stopped.
Be careful not to touch the oil when
loosening the cap or plug. Working on
the machine under these conditions
could result in burns or injuries due to
the hot oil spurting out.
• Oil may spurt out if caps or filters are
removed or pipes are disconnected
before releasing the pressure in the
hydraulic system.
· Press the air breather button to relieve
the internal pressure from the tank.
· When removing plugs or screws, or
when disconnecting hoses, stand to
the side and loosen them slowly to
gradually release the internal pressure
before removing.
1. Slew 60° clockwise and set the machine
to the hydraulic oil level inspection
posture.
Refer to “Inspecting the hydraulic oil tank
level and replenishing” on page 5-22.
2. Open the right side cover.
