Safety Instructions

This manual contains information that is
very important to know and understand.
This information is provided for SAFETY
and to PREVENT EQUIPMENT PROB­LEMS. To help recognize this information,
observe the following symbols.

Safety Signal Words

Danger indicates an imminently haz­ardous situation which, if not avoided,
WILL result in death or serious injury.

Warning indicates a potentially haz­ardous situation which, if not avoided,
COULD result in death or serious injury.

Caution indicates a potentially hazardous
situation which, if not avoided, MAY
result in minor or moderate injury.

Notice indicates important information,
that if not followed, may cause damage
to equipment.

Since the air compressor and other com­ponents (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 safety codes as well
as the United States 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
(meeting ANSI Z87.1 or
in Canada CSA Z94.3-99)
and use hearing protec­tion when operating the pump or unit.
Everyday glasses are not safety
glasses.

6. Do not stand on or use the pump or
unit as a handhold.

7. Before each use, inspect compressed
air system, fuel 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.

9. Do not wear loose clothing or jewelry
that will get caught in the moving
parts of the unit.

Before Using the Air Compressor

Never operate
compressor without
a beltguard. Com­pressors can start automatical­ly without warning. Personal
injury or property damage
could occur from contact with
moving parts.

Compressor parts
may be hot even if
the unit is stopped.

CAUTION:

10. Keep fingers away from a running
compressor; fast moving and hot
parts will cause injury and/or burns.

11. 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.

12. Check fuel level before starting the
engine. Do not fill the gas tank
indoors. Wipe off any spilled gas
before starting the engine.

13. To reduce fire hazard, keep
engine/motor exterior free of oil, sol­vent, or excessive grease.

14. Do not tamper with governor setting
on engine. Overspeeding the unit
severely shortens engine life and may
also be very hazardous.

15.

Tanks rust from moisture build-up,
which weakens the tank. Make sure to
drain tank daily and inspect periodical­ly for unsafe conditions such as rust
formation and corrosion

Safety Instructions (continued)

NEVER refuel a run­ning or hot engine.
Explosive fuel can cause fires
and severe burns. Avoid over­filling fuel tank.

Gasoline vapor is highly flam­mable. Refill outdoors or only in
well ventilated areas. Do not
store, spill or use gasoline near
an open flame or heat devices
such as a stove, furnace, or
water heater, which utilize a
pilot light, or any device that
can create a spark. If gasoline
is accidentally spilled, move
unit away from the spill area
and avoid creating any source
of ignition until gasoline vapors
have dissipated.

Motors, electrical
equipment and con­trols can cause electrical arcs
that will ignite a flammable gas
or vapor. Never operate or

Carbon monoxide can
cause severe nausea,
fainting or death. Do
not operate unit
inside a closed building or a
poorly ventilated area.

repair in or near a flammable
gas or vapor. Never store flam­mable liquids or gases in the
vicinity of the compressor.

Never remove or attempt to
adjust safety valve. Keep safety
valve free from paint and other
accumulations.

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.

DANGER:

16. Fast moving air will stir up dust and
debris which may be harmful.
Release air slowly when draining
moisture or depressurizing the com­pressor system.

17.

STOP the engine whenever leaving the
work area, before cleaning, making
repairs or inspections. When cleaning,

repairing or inspecting, make certain all
moving parts have stopped. Disconnect
the spark plug wire and keep the wire
away from the plug to prevent acciden­tal starting.

18. Allow engine to cool before storing.

19. Do not smoke when spraying paint,

insecticides, or other flammable sub­stances.

20. Use a face mask/respirator when

spraying and spray in a well ventilat-

ed area to prevent health and fire
hazards.

21. 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.

22. When spraying or cleaning with sol­vents or toxic chemicals, follow the
instructions provided by the chemical
manufacturer.

Spraying Precautions

Do not spray flam­mable materials in
vicinity of open
flame or near ignition sources
including the compressor unit.

Breathable Air Warning

This compressor/pump is not equipped and should not be used “as
is” to supply breathing quality air. For any application of air for
human consumption, the air compressor/pump will need to be fitted
with suitable in-line safety and alarm equipment. This additional
equipment is necessary to properly filter and purify the air to meet
minimal specifications for Grade D breathing as described in
Compressed Gas Association Commodity Specification G 7.1 - 1966,
OSHA 29 CFR 1910. 134, and/or Canadian Standards Associations
(CSA).
DISCLAIMER OF WARRANTIES
In the event the compressor is used for the purpose of breathing air
application and proper in-line safety and alarm equipment is not
simultaneously used, existing warranties shall be voided, and
Campbell Hausfeld disclaims any liability whatsoever for any loss,
personal injury or damage.

ASME Safety Valve

A safety valve that automatically releases
the air if the air receiver (tank) pressure
exceeds the preset maximum.

PSI (Pounds per Square Inch)

Measurement of the pressure exerted by
the force of the air. The actual psi output
is measured by a pressure gauge on the
compressor

SCFM (Standard Cubic Feet per
Minute)

Sometimes called CFM (Cubic Feet per
Minute). Measurement of air volume
delivered by the compressor.

Air Delivery

A combination of psi and SCFM. The air
delivery required by a tool is stated as
(number) SCFM at (number) psi. The
combination of these figures determines
what size unit is needed.

Air Tank Capacity

The volume of air stored in the tank and
available for immediate use. A large tank
allows the intermittent use of an air tool
with an air requirement higher than the
compressor’s rated delivery.

Regulator

A control that adjusts the line pressure to
the proper amount needed to operate
spray guns and air tools.

Tank Pressure Gauge

Indicates tank pressure in psi.

Line Pressure Gauge

Displays the current line pressures. It is
regulated by the regulator knob.

Cut-in/Cut-off Pressure

Specific psi at which a compressor starts
and stops while refilling the air tank.

Glossary of Terms

1. Remove the air compressor from the
carton.

2. Place the compressor on a secure,
stationary work surface and look it
over carefully.

Unpacking and Checking Contents

Do not operate unit if damaged
during shipping, handling or
use. Damage may result in
bursting and cause injury or
property damage.

For your own safety, never
operate unit until all assembly
steps are complete and until
you have read and understood
the entire operator’s manual.

To reduce the risk of injury, if
any parts are missing, do not
attempt to assemble the air
compressor until the missing
parts are obtained and installed
correctly.
