11. Oil and install o--ring. Install inlet adapter; se-
cure with snap ring.
NOTE
After installation, make sure the snap ring is prop-
erly seated into the groove.

COMPRESSOR/MOTOR REMOVAL
W ARNING
!
Before doing compressor maintenance, discon-
nect compressor from power source and lock out
power source. Isolate compressor from line pres-
sure by closing recommended discharge shut--
off valve and releasing all internal pressure from
compressor.
Ref er t o lif t ing dec al in S ec t ion 9. 11. S hould it be-
come necessary to remove the compressor/motor
assembly from the compressor package, care must
be taken to lift properly.
The main lift points on the compressor/motor as-
sembly are at the air filter support bracket mounting
hole on top of the main body of the compressor and
the eye bolt on top of the motor. Insert a suitable lift-
ing device into the main compressor body hole.
The compressor/motor assembly may also be lifted
using a forklift truck with fork extensions. To lift the
entire assembly from beneath the compressor use
supporting blocks for the motor. Position the blocks
on the forks beneath the motor to assure lifting the
assembly level.
W ARNING
!
Follow all appropriate SAFETY SECTION instruc-
tions and practices when lifting this assembly.
In the event a new factory replacement compressor
unit is required, the compressor unit must be pre--lu-
bricated prior to operation.
NOTE
When adding fluid to the compressor unit be cer-
tain it is the identical fluid use d originally in the lu-
brication system.
Pre--lubricating the compressor unit requires adding
approximately 1/2 gallon (1.9 liters) of lubricant
through the inlet port. This is accomplished by
pushing the inlet check valve (reference Figure 7--5)
open and pouring lubricant directly into the inlet.
NOTE
Clean all parts and surfaces prior to pre--lubrica-
tion procedure. Extreme care must be taken to
avoid contamination of the compressor fluid.
Check compressor sump housing for proper fluid
level prior to start--up.
COMPRESSOR COOLER CLEANING -- AIR-
COOLED
Ref er t o F igur e 7 -- 6.
W ARNING
!
Before doing compressor maintenance, discon-
nect compressor frompower source and lock out
power source. Isolate compressor from line pres-
sure by closing recommende d discharge shutoff
valve and releasing all internal pressure from
compressor.
To access the compressor cooler if cleaning is re-
quired follow the procedure below.
1. Remove all necessary hardware fastening cooler
shroud to the compressor enclosure.
2. Lift cooler shroud up and away from compressor
enclosure and cooler.
3. Disconnect fluid cooler lines that are attached to
cooler . Plug cooler and lines to avoid fluid con-
tamination.
4. Flush dirt from the cooler fins with low pressure
air or water.
5. Assemble cooler in reverse order of disassembly.
6. Once compressor is assembled, check fluid for
proper level.
