MAINTENANCE
AFTER THE INITIAL 50 HOURS (ONLY FOR NEW MACHINES)
REPLACING THE HYDRAULIC OIL
RETURN FILTER
WARNING
• Stop the engine and allow the machine
to cool down before performing
maintenance.
· The engine and the hydraulic system
and many other parts of the machine
are hot immediately after the engine is
stopped. Touching these parts will
cause burns.
· The hydraulic oil is also hot and under
high pressure.
Be careful not to touch the hydraulic
oil when loosening the cap or plug.
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 are disconnected
before releasing the pressure in the
hydraulic system.
· When removing plugs or screws, or
when disconnecting hoses, stand to
the side and loosen them slowly to
gradually release the internal pressure
before removing.
1. Loosen the bolts and remove the cover
(3).
2. Remove the plug (1).
3. Loosen the bolts and remove the flange
(4).
4. Remove the return filter (5).
5. Install a new return filter.
6. Reinstall the flange (4).
7. Inspect the level with the sight gauge (2),
and replenish if the level is too low.
Refer to “Inspecting the hydraulic oil tank
level and replenishing” on page 5-19.
14. Add oil up to between the upper limit (H)
and the lower limit (L) of the dipstick (1).
Problems could arise if the oil level is
either too low or too high.
15. Tighten the oil filler cap (2).
16. Lower the canopy.
17. Start the engine, run it at low idle for
about 5 minutes, then stop it.
18. After about 10 minutes, inspect the oil
level.
