7.7 Hydraulic Oil Change
The hydraulic oil should be
changed every 500 service
hours. Before beginning the pro-
cedure, make sure the machine
is in a clean working environ-
ment. Take any necessary
measures to prevent dirt or
debris from entering the
hydraulic system.
To change hydraulic oil and filter:
1.
Park the machine in a location suitable for performing service
work, lower the lift arms, stop the engine and remove the key.
2. Allow the machine to cool, then release any residual pressure
in the hydraulic system by following the procedure in section
4.5 of this manual.
3. Locate and remove the hydraulic fluid drain plug (item 1)
through the drain hole in the belly pan. (fig. 7.7-1)
4. Drain the used oil into a suitable catch container.
5. Dispose of the oil according to local mandates.
6. Reinstall the drain plug and tighten.
7. Refill the hydraulic reservoir (item 3) with Chevron Rykon MV
Hydraulic Oil, or equivalent. (fig. 7.7-2)
Note: Observe the hydraulic oil level sight gauge (item 4) located on
the back of the hydraulic reservoir to ensure that the level is correct
(fig. 7.7-3).
8. Once full, start the engine according to the proper starting pro-
cedure and operate all hydraulic circuits to work any trapped air
out of the system. Then, check the oil level. If low, add oil as
necessary until full.
