MAINTENANCE
Every 2000 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.
�
Never jump off the machine. Use the
steps and handrails when climbing on
and off the machine, and always support
your body at three points with your
hands and feet.

Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• Gradually press the air breather button
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
