37. Make sure that the lubricator is full and is me-
tering oil to the air motor. Do this by turning off
the main Power Pack valve, removing the main air
hose from the Power Pack to the Spinmaster and
turning the main valve on again. Air should flow
into the atmosphere with a very light oil mist that
would coat your hand. Now check the lubricator
drip adjustment. If the air lubricator is not func-
tioning correctly, rust could disable the air motor.
See Air Lubricator Adjustment Maintenance page

 Make sure the Power Pack main air valve is fully
open. See Power Hook-Up pg.11.
 Make sure that the air supply (volume and Pressure)
from the rig source is sufficient to get maximum
performance from the main Spinmaster motor
(250-300 scfm @100 psi).
 Make sure that the air hose from the rig air supply
to the Spinmaster Power Pack is at least 1 1/4"
in size (1 1/2" air hose gives best performance
especially when the supply hose is longer than 25
foot) or the Spinmaster air motor will starve for
air. See Power Hook-up pg.11. In addition, any
fittings that are on the air supply hose to the Power
Pack must have equal or greater flow capacity as
the supply hose.
 The air filter on the Power Pack may be clogged.
See Changing Air Filter Element pg.33.
 The muffler on the Spinmaster air drive motor could
be restricting the air flow through the motor.
Clean or replace the muffler. For part number see
Drawings pg.48,52.
 The gripping pressure output on the Power Pack
could be set too high. For proper adjustment, see
Adjusting Grip Pressure pg.34.
 The drive rollers could be touching one another
