high pressure pumping system, the fol-
lowing safety precautions should be
observed at all times. Only persons well
acquainted with these rules of safe oper-
ation should be allowed to use the air
compressor.
from damage or puncture. Keep hose
and power cable away from sharp
objects, chemical spills, oil, solvents,
and wet floors.
5. Never point a spray gun at oneself or
any other person. Accidental dis-
charge may result in serious injury.
6. Check hoses for weak or worn condi-
tion before each use, making certain
all connections are secure; do not
use if deficiency is found. Notify an
authorized service facility for exami-
nation or repair.
!
WARNING:
All electrical work should be
done by a qualified (licensed or
certified) electrician. On a prop-
erly wired circuit, the black
wires supply a voltage potential
even when the unit is off.
7. Release all pressures within system
slowly; dust and debris may be harm-
ful.
1. Read instruction manuals for each
component carefully, before attempt-
ing to assemble, disassemble or
operate your particular system.
!
WARNING:
Disconnect power and depres-
surize system before servicing
air compressor! (Turn pressure
regulator knob fully clockwise
after shutting off compressor.)
2. 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.
3. Do not exceed pressure rating of any
component in system.

Safety Instructions (continued)
8. Follow all local electrical and safety
codes, as well as the National
Electrical Code (NEC) and the
Occupational Safety and Health Act
(OSHA).
19. When spraying with solvent or toxic
chemicals, follow instructions provid-
ed by the chemical manufacturer.
20. Spray in a well ventilated area, to
keep fumes from collecting and caus-
ing health and fire hazards.
9. Wiring and fuses should follow electri-
cal codes, current capacity, and be
properly grounded.
21. 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.
10. Electric motors must be securely and
adequately grounded. See grounding
instructions and extension cord infor-
mation in this manual.
22. Use a respirator when spraying.
11. Always disconnect power source
before working on or near a motor, or
its connected load. If power discon-
nect point is out-of-sight, lock it in the
open position and tag to prevent
unexpected application of power.
23. NEVER reset safety valve or pres-
sure switch. Keep safety valve free
from paint and other accumulations.
This provides safety against over
pressure.
24. Do regular maintenance; keep all
nuts, bolts, and screws tight, to be
sure equipment is in safe working
condition .
12. Guard all moving parts; keep visitors
away. Never allow children in work
area.
13. Use only a properly grounded outlet
that will accept a three pronged plug,
and wear shoes to prevent shock
hazards.
25. Keep cleaning rags and other flam-
mable waste materials in a tightly
closed metal container and dispose of
later in the proper fashion.
14. Be careful when touching exterior of
operating motor; it may be hot
enough to cause injury.
26. 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 com-
pletely drain out and help prevent
corrosion of inside of tank.
15. Protect power cable from coming in
contact with sharp objects.
16. Clean electrical or electronic equip-
ment with an approved cleaning
agent, such as dry, nonflammable
cleaning solvent.
27. 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.
17. To avoid spontaneous combustion,
discard waste rags into approved
metal waste cans.
28. Do not wear loose clothing or jewelry
that will get caught in the moving
parts of the unit.
18. Never store flammable liquids or
gases in vicinity of compressor.

Spraying Precautions
3. 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 com-
pressor.
!
WARNING:
Do not spray flamma-
ble materials in vicin-
ity of open flame or
near ignition sources including
the compressor unit.
4. When spraying or cleaning with sol-
vents or toxic chemicals, follow the
instructions provided by the chemical
manufacturer.
1. Do not smoke when spraying paint,
insecticides, or other flammable sub-
stances.
2. Use a face mask/respira-
tor when spraying and
spray in a well ventilated
area to prevent health and
fire hazards.

WHAT IS COVERED UNDER THE LIMITED THREE YEAR WARRANTY

pressor for the three-year period from the date of purchase. This warranty is specif-
ic to this air compressor. Warranties for other RIDGID products may vary.
HOW TO OBTAIN SERVICE
To obtain service for this RIDGID air compressor you must return it, freight prepaid,
to a service center authorized to repair RIDGID air compressors. You may obtain the
location of the service center nearest you by calling (toll free) 1-800-4-RIDGID or by

and either repair or replace any defective part, at Campbell Hausfeld’s option at no
charge to you.
WHAT IS NOT COVERED
This warranty applies only to the original purchaser at retail and may not be trans-
ferred. This warranty does not cover normal wear and tear or any malfunction, fail-
ure or defect resulting from misuse, abuse, neglect, alteration, modification or repair
by other than a service center authorized to repair RIDGID branded air compressors.
Expendable materials, such as oil, filters, etc. are not covered by this warranty.
Gasoline engines and components are expressly excluded from coverage and you

Any implied warranties, including warranties of merchantability or fitness for a par-
ticular purpose, that cannot be disclaimed under state law are limited to three years
from the date of purchase. Campbell Hausfeld is not responsible for direct, indirect,
incidental, special or consequential damages. Some states do not allow limitations
on how long an implied warranty lasts and/or do not allow the exclusion or limitation
of incidental or consequential damages, so the above limitations may not apply to
you. This warranty gives you specific legal rights, and you may also have other
rights, which vary from state to state.
