Maintenance
INTAKE FILTER
1. Remove the front panel of the unit.
2. Remove the air inlet housing, the
wing nut and the inlet filter ele-
ment.
3. Clean the inlet filter element with
compressed air or replace with a
new element.
NOTE: Never clean filter element with
solvents or water.
VENTILATION SCREEN
1. Remove the ventilation screen
located at the rear of the unit (#) or
the right hand panel (*).
2. Clean with compressed air or soap
and water, if necessary.
INSPECT V-BELT TENSION
1. Check V-Belt tension with tension
gauge.
2. Adjust to the specifications listed in
Chart 17.
GREASE COMPRESSOR BEARINGS
1. Remove the plastic dust cap (Key
#69) from the air end. See Figure 4.
2. Move the compressor pulley until
the grease fitting is visible through
the dust cap hole.
3. Use a grease gun extension adapter
to engage the grease fitting and
supply the proper volume of grease
as indicated on the grease delivery
chart. See Chart 18.
Use only Powerex
genuine grease.
(Part # IP600000AV). Pump grease gun
before feeding to eliminate air from
grease passage of the needle adapter.
GREASE PIN CRANK BEARING
1. Remove the V-Belt and the fan
cover (Key #24).
2. Remove the air end pulley with a
gear puller.
3. Remove the fan duct (Key #22).
4. Remove the three grease caps (Key
#72). Do not attempt to loosen or

Chart 18 - Grease Delivery
Use only Powerex genuine grease, (Part
#IP600000AV), or equivalent.
NOTE: Each pump of the grease gun equals 0.65g of grease.
The volume of grease is less after the 2nd pump since some
of the grease supply will remain in the grease passage.
!
CAUTION
The grease fitting,
located in the cen-
ter of the pin crank bearing, feeds only
the orbit scroll side bearing. Use a nee-
dle adapter to supply grease to the
housing side bearing. Pump grease gun
before feeding to eliminate air from
grease passage of the needle adapter.
Hold grease gun for 5 - 10 seconds after
feeding to prevent grease blowback
from the grease fitting.
