MAINTENANCE
Every 4000 Hours
Replacing the Hydraulic Oil and
Cleaning the Suction Strainer
WARNING
�
Stop the engine and allow the machine
to cool down 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 the hot oil
spurting out.
�
Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• Gradually loosen the vent plug to
relieve tank pressure.
• When removing plugs or screws or
disconnecting hoses, stand to the
side and loosen slowly to gradually
release the internal pressure before
removing.

the machine to the hydraulic oil level
inspection posture.
Refer to page 106 “Inspecting the
