WIRING
1.
Local electrical wiring codes differ
from area to area. Source wiring,
plug and protector must be rated
E
for at least the amperage and
voltage indicated on motor
N
nameplate, and meet all electrical
G
codes for this minimum.
L
I
2.
Use a slow blow fuse or a circuit
breaker.
S
H
Overheating, short circuiting and fi re
damage will result from inadequate
wiring, etc.
NOTE: 120 volt, 15 amp units can be
operated on a 120 volt circuit under the
following conditions:
a. No other electrical appliances
or lights are connected to the
same branch circuit.
b. Voltage supply is normal.
c. Circuit is equipped with a 15
amp circuit breaker or a 15
amp slow blow fuse.
3.
If these conditions cannot be met or
if nuisance tripping of current
protection device occurs, it may be
necessary to operate compressor
from a 120 volt, 20 amp circuit.
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 fi lter in
the air line (6ZC63), located as near to
the gun as possible, will help eliminate
this moisture.

Oilless Compressor
Operation
DEFINITION OF TERMS
Pressure Switch - ON / OFF Switch - In
the ON position, the compressor shuts
off automatically when tank pressure
reaches the maximum preset pressure.
In the OFF position, the compressor will
not operate. This switch should be in
the OFF position when connecting or
disconnecting the power cord from the
electrical outlet or when changing air
tools.
ASME Safety Valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Discharge Tube - This tube carries
compressed air from the pump to the
check valve. This tube becomes very hot
during use. To avoid the risk of severe
burns, never touch the discharge tube.
Check Valve - One-way valve that
allows air to enter the tank, but
prevents air in the tank from fl owing
back into the compressor pump.
Drain Valve - This valve is located on
the bottom of the tank. Use this valve
to drain moisture from the tank daily to
reduce the risk of corrosion.
Outlet Pressure Gauge
Regulator
Air Hose Attachment

Regulator - The regulator controls
the amount of air pressure at the
hose outlet. Turning regulator knob
clockwise (to the right) will increase air
pressure at the outlet. Turning knob
counterclockwise (to the left) will lower
air pressure to the outlet. Turning knob
fully counterclockwise will shut off fl ow
of air completely.
Pressure Gauges - These gauges will
show air pressure in the compressor tank
and at the compressor outlet.
Outlet Pressure Gauge - Will show
air pressure at the outlet in pounds per
square inch (psi). Make sure this gauge
reads ZERO (by adjusting regulator knob
fully counterclockwise) before changing
air tools or disconnecting air hose from
outlet.
Tank Pressure Gauge - Will show air
pressure in tank while the compressor
is running, indicating compressor
is building pressure properly. This
gauge will show maximum pressure
of compressor when it shuts off
automatically at the pressure switch.
