MAINTENANCE
After First 50 Hours (New Machines Only)
Replacing the Pilot Line 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.
• When removing plugs or screws or
disconnecting hoses, stand to the
side and loosen slowly to gradually
release the internal pressure before
removing.
If you must work beneath the raised
dump body, securely engage the raised
body prop. Never get under the dump
body if it is not sufficiently supported.
1. Start and run the engine at low speed.
2. Fully raise the dump body.
3. Set the safety lock lever to the lock
position, and stop the engine.
4. Securely engage the raised body prop.
5. Remove the cover (4).
6. Turn the case (1) counterclockwise and
remove it.
7. Remove the element (2) and O-ring (3).
8. Clean the inside of the case (1).
9. Install the new element in the case (1).
10. Set the new O-ring, then tighten the case
(1).
11. Inspect the level with the sight gauge,
and replenish if the level is low.

Hydraulic Oil Level and Replenishing”.
