MAINTENANCE
144
Every 1000 Hours
Replacing the Hydraulic Oil and
Cleaning the Suction Strainer
WARNING
Stop the engine and allow the
machine to cool before performing
maintenance.
• The engine, hydraulic lines and many
other parts of the machine are hot
directly after the engine is stopped.
Touching these parts will cause
burns.
• The hydraulic fluid is also hot and
under high pressure.
Be careful when loosening caps and
plugs. Working on the machine under
these conditions could result in burns
or injuries due to hot oil spraying
out.
Oil may spray out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• When removing plugs or screws or
disconnecting hoses, stand to the
side and loosen slowly, to gradually
release the internal pressure before
removing.
1. Open the rear door.
2. Drain the coolant.
Refer to page 142, “Cleaning the Engine
Cooling System.”
3. Place a pan for catching the waste oil
under the drain plug (7).
4. Loosen the drain plug (7) and drain the
hydraulic oil.
5. Remove the bolts (a) and open the radiator
/ oil cooler (b).
6. Disconnect the hoses that are connected
to the radiator / oil cooler (b).
7. Temporarily suspend the radiator / oil
cooler (b).
