3. Remove the dipstick and wipe it with a clean
rag, then screw the dipstick back into the tank.
4. Remove the dipstick and check the fluid level. If
the fluid is between the marks on the dipstick,
the level is sufficient. If the fluid level is not
between the marks, more fluid is needed.
5. Remove the cap or dipstick (depending on your
machine) from the hydraulic fluid tank and slowly
fill the tank with the appropriate high-quality
hydraulic fluid until the level is between the 2
marks on the sight window or dipstick.
Note:
Do not mix fluids.
6. Install the cap.
Note:
Perform a close visual inspection of the
hydraulic components. Inspect them for issues
(e.g., leaks, loose fasteners, missing parts, and
improperly routed lines). Make any necessary
corrections.

Note:
If you will not be draining the fluid,
disconnect and plug the hydraulic line going to
the filter.
2. Fill the replacement filter with the appropriate
hydraulic fluid, lubricate the sealing gasket, and
hand turn it until the gasket contacts the filter
head. Then tighten it 3/4 turn further.
3. Fill the hydraulic reservoir with hydraulic fluid;
refer to Hydraulic Fluid Specifications (page 42)
and Checking the Hydraulic-Fluid Level (page
43).
4. Start the machine and run it at idle for 3 to 5
minutes to circulate the fluid and remove any air
trapped in the system. Shut off the engine and
check the fluid level.
5. Dispose of the fluid and filter properly.
