CLEANING AND INSPECTION
WARN I N G
Solvent cleaning compound MIL-PRF-680 Type III is an environmentally compliant and low-toxic
material. However, it may be irritating to the eyes and skin. Use protective gloves and goggles. Use in
well-ventilated areas. Keep away from open flames and other sources of ignition. Failure to do so may
result in injury or death to personnel.
Particles blown by compressed air are hazardous. DO NOT exceed 15 psi (103 kPa) nozzle pressure
when drying parts with compressed air. DO NOT direct compressed air against human skin. Make
sure air stream is directed away from user and other personnel in the area. To prevent injury, user
must wear protective goggles or face shield. Failure to follow this warning may result in injury to per-
sonnel.
1.
Clean all parts and mating surfaces with solvent cleaning compound.
2.
Dry parts with compressed air.
3.
Inspect all parts for wear, pitting, cracks, or corrosion and replace if necessary.
4.
Inspect oil passages to ensure they are clean and unobstructed.
5.
Inspect gasket on hydraulic filler cap and replace if damaged or worn.
FILL AND FILTER INSTALLATION
N OT E
Hydraulic system capacity is 29 gal. (110 L).
1.
Apply a thin coat of clean oil to seal on two new filters (8).
N OT E
Note positions of index marks on filters
in relation to a fixed point on mounting
bases. There are index marks on each
filter spaced 90 degrees (or 1/4 of a turn)
apart. When tightening filters, use
rotation index marks as a guide. Then
turn filters an additional 1/2 turn.
2.
Install two new filters (8) hand-tight until seals contact
mounting bases (9).
3.
Fill hydraulic tank with clean oil until level is at
"FULL" mark on sight gage (10).
