Check the hydraulic fluid level after every
100 hours of operation. It should be above the “add”
marks on the dipstick, but not above the “full” mark
when the hydraulic fluid is warm.
Do not overfill the hydraulic fluid reservoir. Hydraulic
fluid expands as it heats to its normal operating
temperature. Always allow for expansion when filling
the reservoir.
ATTENTION! Do not overfill the hydraulic fluid
reservoir or operate the machine with a low level
of hydraulic fluid in the reservoir. Damage to the
machine hydraulic system may result.
Drain and refill the hydraulic fluid reservoir with
hydraulic fluid after every 400 hours of operation.
The hydraulic system is kept clean to a level of
10 microns by a hydraulic fluid filter. The hydraulic
fluid filter is located under the radiator. Replace the
filter element after every 400 hours of operation.
A reservoir outlet strainer is built into the reservoir to
filter hydraulic fluid before it enters the system.
Replace the strainer after every 800 hours of
operation.
TO DRAIN HYDRAULIC FLUID RESERVOIR AND
REPLACE 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. Allow the hydraulic fluid to cool.
3. Unthread and discard the hydraulic fluid filter
element. Hydraulic fluid will drain through the
filter head. Discard the used hydraulic fluid.

HYDRAULIC FLUID FILTER
A. Filter Element
B. Machine Frame
NOTE: Be aware the hydraulic filter is lower than the
reservoir. All fluid will drain from the reservoir.
Discard all hydraulic fluid drained from the system. It
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.
