WARNING
High pressure air can cause severe injury or death
from hot oil and flying parts. Always relieve
pressure before removing caps, plugs, covers or
other parts from pressurized air system.
1. Open the service air valve(s) to ensure that
system is relieved of all pressure. Close the
valve(s).
2. Turn the spin--on filter element counterclockwise
to remove it from the filter housing. Inspect the filter.
NOTICE
If there is any indication of formation of varnishes,
shellacs or lacquers on the oil filter element, it is a
warning the compressor lubricating oil has im-
proper characteristics and should be immediately
changed.
3. Inspect the oil filter head to be sure the gasket was
removed with the oil filter element. Clean the gasket
seal area on the oil filter head.
RUNNING GEAR
Every month or 500 miles, tighten the wheel lug nuts to
85 -- 95 lbs.--ft. Every six months the wheel bearings,
grease seals and axle spindles should be inspected for
damage (corrosion, etc.) or excessive wear. Replace
any damaged or worn parts. Repack wheel bearings.
Use a wheel bearing grease conforming to
specification MIL--G--10924 and suitable for all
ambient temperatures.
Grease can be replaced in a wheel bearing using a
special fixture or by hand as follows.
Before installing bearing, place a light coat of grease
on the bearing cups which are pressed in the hub.
NOTICE
Installing a new oil filter element when the old
gasket remains on the filter head, will cause an oil
leak and can cause property damage.
4. Lubricate the new filter gasket with the same oil
being used in the machine.
5. Install new filter by turning element clockwise until
gasket makes initial contact. Tighten an additional 1/2
to 3/4 turn.
6. Start unit and allow to build up to rated pressure.
Check for leaks before placing unit back into service.
FASTENERS
Visually check entire unit in regard to bolts, nuts and
screws being properly secured. Spot check several
capscrews and nuts for proper torque. If any are found
loose, a more thorough inspection must be made.
Take corrective action.
COMPRESSOR OIL
The lubricating and cooling oil must be replaced every
500 hours of operation or six (6) months, whichever
comes first.
