MOISTURe In COMPReSSeD AIR

Moisture in compressed air will form
into droplets as it comes from an air
compressor pump . When humidity is high
or when a compressor is in continuous
use for an extended period of time, this
moisture will collect in the tank . When
using a paint spray or sandblast gun,
this water will be carried from the tank
through the hose, and out of the gun as
droplets mixed with the spray material .
IMPORTAnT: This condensation will cause
water spots in a paint job, especially
when spraying other than water based
paints . If sandblasting, it will cause the
sand to cake and clog the gun, rendering
it ineffective .
A filter in the air line, located as near to
the gun as possible, will help eliminate
this moisture .
Maintenance (Continued)
4 . Check the safety valve by
performing the following steps:
a . Plug the compressor in and run
until shut off pressure is reached
(see Operating Procedure) .
b . Wearing safety glasses, pull the
ring on the safety valve to release
pressure from compressor tank .
Protect yourself from fast-moving
air being released; do not allow
fast-moving air to be directed
toward your face (See Figure 12) .
Figure 12
c . The safety valve should
automatically close at
approximately 40-50 PSI . If the
safety valve does not allow air
to be released when you pull
on the ring, or if it does not
close automatically, it MUST be
replaced .

tension / alignment . To adjust belt:
a . Remove belt guard .
b . Remove belt .
c . Loosen the four fasteners holding
the motor to the baseplate .
d . Shift the motor in the proper
direction . Tighten the four
fasteners holding motor to
baseplate . The belt must
be properly aligned when
adjustment is made .
e . To align belt, lay a straightedge
against the face of the flywheel
touching the rim at two places
(See Figure 13) .
