Replacing Hydraulic Oil
To do so:
1. Empty the hydraulic tank (see Emptying the Hydraulic Tank on page 115).
2. With a clean dry cloth attached to a stick, remove all metal particles and debris accumulated at
the bottom of the hydraulic tank:
2 a. Remove the access panel (see Figure 5-27).
2 b. Remove the strainer. See Cleaning the Strainer on page 117.
2 c. Clean or replace the strainer if necessary.
2 d. Remove the return filter housing (see Figure 5-27).
2 e. Insert your hand inside and clean the interior of the tank with a dry clean cloth.
2 f. Clean the return filter housing with a dry clean cloth.
3. Change the return filter element (see Replacing Filter Elements on page 120).
4. Reinstall the access panel, the strainer and the return filter housing.
5. Using a filtering screen, refill the tank with high quality oil until it reaches the ¾ mark on the oil
gauge (see Recommended Lubricants on page 69 for specifications).
NOTE: Oil must be clean and free of any contaminants (dirt, metal particles, sand, etc.).
Caution!
Highly contaminated hydraulic fluid must be changed promptly to avoid damaging the
hydraulic system.
