9.5 Change the Hydraulic Fluid and
Filter
WARNING!
Read and understand
Hydraulic System Safety
on page 30
.
CAUTION!
Risk of burns to exposed skin.
Hydraulic fluid gets hot during
operation, which makes hoses,
lines, and other parts hot as well.
Wait for the fluid and components to
cool before starting maintenance or
service.
Change the hydraulic fluid and filter every 100 hours of
operation or annually.
Wait for the machine to cool down before changing the hydraulic
fluid. However, it is best to change the fluid while the machine is
warm to keep any contaminants in suspension.
The filter is located on the back, RH side of the hydraulic-fluid
reservoir, below the step.

The drain plug is located on the bottom of the machine, on the
RH side of the hydraulic fluid reservoir, below the filter. The drain
plug must be removed to fully drain the fluid.

1. Set the machine to a safe condition.
For instructions, see
Safe Condition on page 9 .
2. Place a drain pan under the drain plug and filter. Make sure
that the drain pan is large enough to collect and contain the
hydraulic fluid that will drain from the filter and reservoir.
3. Clean the area around drain and remove the drain plug.
4. Remove the filter. A filter wrench may be required.
5. Wait for the hydraulic fluid to fully drain from the reservoir
and filter connection.
6. Apply a light coat of clean lubricant to the seal, and then
install the new filter. Only tighten it by hand.
7. Install the drain plug.
8. Fill the reservoir to the top mark on the dipstick with Dexron
III ATF or an acceptable substitute.
The reservoir capacity
is 8 US gal (30 L) .
For more information, see Add Hydraulic Fluid to the
Reservoir on page 31 .
9. Start the machine.
For instructions, see
Start the Machine on page 33 .
10. Advance and retract the splitter push block for 1–2 minutes
to remove air from the hydraulic system.
11. Check the filter head for leaks.
12. Stop the machine.
For instructions, see
Stop the Machine on page 34 .
