5. Add hydraulic fluid until the level in the reservoir
is between the “ADD” and the “FULL” range. Do
not overfill.
NOTE: Do not overfill the hydraulic fluid reservoir. As
hydraulic fluid heats to its normal operating
temperature, it expands. Always allow for this
expansion when filling the hydraulic fluid reservoir.
6. Place the reservoir breather-filler cap securely
on the reservoir filler neck.
7. Lower the operator seat.
8. Start engine and operate all of the hydraulic
components. Then recheck the hydraulic fluid
level.
HYDRAULIC FLUID RESERVOIR BREATHER
The hydraulic fluid reservoir is equipped with a
breather. The breather relieves excess atmospheric
pressure or vacuum in the reservoir. The breather is
mounted on the hydraulic fluid reservoir filler neck
located under the operator seat. The breather should
be replaced after every 800 hours of operation.

HYDRAULIC FLUID FILTER
The machine hydraulic system is kept clean to a
level of 10 microns by a hydraulic fluid filter. The
hydraulic fluid filter is located in the left front of the
machine engine compartment.
Replace the hydraulic fluid filter element after the first
50 hours of operation and then after every 400 hours
of operation.
TO REPLACE HYDRAULIC FLUID FILTER ELEMENT
1. Stop the engine and set the machine parking
brake.
FOR SAFETY: Before leaving or servicing
machine; stop on level surface, set parking brake,
and turn off machine.
2. Open the side engine access door.

3. Unthread and discard the hydraulic fluid filter
element.
NOTE: Discard all hydraulic fluid drained from the
system. Drained hydraulic fluid may contain foreign
material harmful to the hydraulic system.
4. Apply a thin coat of hydraulic fluid to the seal of
the new hydraulic fluid filter element.
5. Thread and hand tighten the new hydraulic
fluid filter element on the filter head.
6. Operate the machine and check for leaks.
Correct any leaks found.
7. Check the hydraulic fluid reservoir level and fill
as required.
8. Close the side engine access door.
