Changing the Hydraulic Fluid and Filter
Tools needed:
• 3/4"Wrench
• 7/8" Wrench
• Filter Wrench
1. Place a waste fluid container under Filter and
Connections. Your container must be large enough to
hold the 12.46 gallons of fluid in the Tank.
2. Slightly raise the hitch end of the Backhoe by turning
the Jack Handle clockwise. The hitch end of the
Hydraulic Tank should be slightly higher than the Filter
end.
3. Remove the existing Hydraulic Fluid Filter and properly
dispose of it (Figure 37).
4. Let the Hydraulic Fluid drain into the container.
5. Apply a thin coat of fresh hydraulic fluid to the Rubber
Seal of the new Hydraulic Fluid Filter.
6. Screw the filter onto the filter head. Once the filter seal
makes contact with the filter head, turn it an additional
¾ turn. Hand-tighten only.
7. Remove the Hydraulic Tank Fill Cap/Dipstick and fill
the Hydraulic Tank with the recommended type and
quantity of hydraulic fluid until the level reaches the fill
mark on the Dipstick (Figure 38). Refer to the Spec
sheet on page 2.
NEVER RUN THE BACKHOE UNLESS THE HYDRAULIC FLUID TANK IS FULL.
