General Safety Information
caLIFOrnIa PrOPOSItIOn 65
This product or its
power cord may
contain chemicals, including lead,
known to the State of California to
cause cancer and birth defects or other
reproductive harm. Wash hands after
handling.
You can
create
dust when you cut, sand,
drill or grind materials
such as wood, paint, metal,
concrete, cement, or other masonry.
This dust often contains chemicals
known to cause cancer, birth defects,
or other reproductive harm. Wear
protective gear.
GeneraL SaFety
Since the air compressor and other
components (material pump, spray
guns, filters, lubricators, hoses,
etc.) used, make up a high pressure
pumping system, the following safety
precautions must be observed at all
times:
1. Read all manuals
included with this
product carefully. Be
thoroughly familiar with
the controls and the proper use of
the equipment.
2. Follow all local electrical and safety
codes as well as in the United
States, the National Electrical Codes
(NEC) and Occupational Safety and
Health Act (OSHA).
3. Only persons well acquainted
with these rules of safe operation
should be allowed to use the
compressor.
4. Keep visitors away and NEVER
allow children in the work area.
5. Wear safety glasses and
use hearing protection
when operating the
unit.
6. Do not stand on or use the unit as
a handhold.
7. Before each use, inspect
compressed air system and
electrical components for signs of
damage, deterioration, weakness
or leakage. Repair or replace
defective items before using.
8. Check all fasteners at frequent
intervals for proper tightness.
Motors,
electrical
equipment and controls can
cause electrical arcs that
will ignite a flammable gas
or vapor. Never operate or repair in or
near a flammable gas or vapor. Never
store flammable liquids or gases in the
vicinity of the compressor.
Compressor parts may
be hot even if the unit is
stopped.
9. Keep fingers away from a
running compressor; fast moving
and hot parts will cause injury and/
or burns.
10. If the equipment should start
to vibrate abnormally, STOP
the engine/motor and check
immediately for the cause.
Vibration is generally a warning of
trouble.
11. To reduce fire hazard, keep engine/
motor exterior free of oil, solvent,
or excessive grease.
An ASME code
safety relief valve
with a setting no higher than 170 psi
MUST be installed in the tank for this
compressor. The ASME safety valve
must have sufficient flow and pressure
ratings to protect the pressurized
components from bursting.
See compressor
specification decal
for maximum operating pressure.
Do not operate with pressure switch
or pilot valves set higher than the
maximum operating pressure.
12. Never attempt to adjust ASME
safety valve. Keep safety valve
free from paint and other
accumulations.
Never use plastic
(PVC) pipe for
compressed air. Serious injury or death
could result.
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, cracked or damaged
tanks.
Drain liquid from
tank daily.
13. Tanks rust from moisture build-up,
which weakens the tank. Make
sure to drain tank regularly and
inspect periodically for unsafe
conditions such as rust formation
and corrosion.
14. Fast moving air will stir up dust
and debris which may be harmful.
Release air slowly when draining
moisture or depressurizing the
compressor system.
SPrayInG PrecaUtIOnS
Do not
spray
flammable materials in
vicinity of open flame
or near ignition sources
including the compressor unit.
15. Do not smoke when spraying paint,
insecticides, or other flammable
substances.
16. Use a face mask /
respirator when spraying
and spray in a well
ventilated area to
prevent health and fire
hazards.
17. 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.
18. When spraying or cleaning with
solvents or toxic chemicals, follow
the instructions provided by the
chemical manufacturer.
Introduction

On/Off Switch
— This unit is
equipped with an illuminated
On / Off switch. In the “
On
” position
the button will be depressed and
the switch will light up. The switch
will remain lit as long as the button
is depressed and there is power to
the unit. The pressure switch will
automatically turn the pump / motor
on or off based on the pressure inside
the tank. If the unit is unplugged the
light will not be on. In the “
OFF
”
position the switch will not be
depressed and the light will not be on.
