General Safety
(Continued)
21. Keep cleaning rags and other
flammable waste materials in a
tightly closed metal container
and dispose of later in the proper
fashion.
22. Drain tanks of moisture after each
day's use. If unit will not be used
for a while, it is best to leave drain
cock open until such time as it is to
be used. This will allow moisture
to completely drain out and help
prevent corrosion of inside of tank.
23. Inspect tank yearly for rust, pin holes
or any other imperfections that
could cause it to become unsafe.
NEVER weld or drill holes in air tank.
24. Household use only.
25. To reduce the risk of electrical shock,
do not expose to rain. Store indoors.
Never attempt to
repair or modify a
tank! Welding, drilling or any other
modification will weaken the tank
resulting in damage from rupture or
explosion. Always replace worn or
damaged tanks.
Drain liquid from
tank daily.
SPRAYING PRECAUTIONS
Do not spray
flammable materials
in vicinity of open flame or near ignition
sources including the compressor unit.
1. Spray in a well ventilated area, to
keep fumes from collecting and
causing health and fire hazards.
2. Do not spray in vicinity of open
flames or other places where a spark
can cause ignition. Do not smoke
when spraying paint, insecticides, or
other flammable substances.
3. Use a respirator when spraying.
4. Do not direct paint or other sprayed
material at the compressor. Locate
compressor as far away from
the spraying area as possible to
minimize overspray accumulation on
the compressor.
5. When spraying or cleaning with
solvents or toxic chemicals, follow
the instructions provided by the
chemical manufacturer.
6. Do not smoke when spraying paint,
insecticides, or other flammable
substances.
7. Use a face mask/
respirator when
spraying and spray in a
well ventilated area to
prevent health and fire
hazards.
8. Do not direct airstream at body.
Introduction
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.
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 flow
of air completely.
Handle - Designed to move the
compressor.
ASME Safety valve - This valve
automatically releases air if the tank
pressure exceeds the preset maximum.
Exhaust 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 exhaust tube.

Check valve - A one-way valve
that allows air to enter the tank, but
prevents air in the tank from flowing
back into the compressor pump.
Air Outlet - A quick connect coupler
designed to work in combination with
a quick connect plug to quickly and
easily join the compressor to an air
hose.
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.
Drain valve - This valve is located
underneath the tank. Use this valve to
drain moisture from the tank daily to
reduce the risk of corrosion.
Reduce tank pressure below 10 psi,
then drain moisture from tank daily to
avoid tank corrosion. Drain moisture
from tank by opening the drain valve
located underneath the tank.
