Replacing the Hydraulic Oil
Return Filter
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 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
removing.
1. Remove cap nut (3) on the air breather
(2).
2. Press button (4) and bleed the air from
the tank.
