Per OSHA
regulations, ALL
power must be locked out before per-
forming any maintenance.
This service should
be performed by an
authorized Powerex Service Center to
avoid failure.
1. Remove the plastic dust cap. Use
only one of two locations found on
the air end (See Figure 2).
2. Rotate the compressor pulley until
the grease fitting is visible through
the dust cap hole (See Figure 2).
This will allow regreasing of the
main bearings.
3. Use a grease gun extension adaptor
to engage the grease fitting and
supply the proper volume of grease
as indicated on the grease delivery
chart (See Grease Delivery chart
below & Figure 2).
Use only Powerex
genuine grease.
Pump grease gun before feeding (this
eliminates air from the grease passage
of the extension adapter. (Complete
Grease Kit Part Number IP616200AJ and
Grease Tube Part Number IP600000AV).
4. Replace plastic dust cap.
The bearings on the scroll compressor
are regreaseable to allow extended
compressor life. Service should be per-
formed every 10,000 hours of opera-
tion.
1. Remove the V-Belts and the fan
cover.
2. Remove the air end pulley and cool-
ing fan with a gear puller (See
Figure 3).

AIR FROM GREASE PASSAGE OF THE
NEEDLE ADAPTER. Hold grease gun for
5 - 10 seconds after feeding to prevent
grease blowback from the grease fit-
ting.
6. Replace grease caps, fan shroud,
pulley, etc.
