Important Safety Instructions
Important Safety Instructions
WARNING: Do not operate this unit until you read and understand
this instruction manual for safety, operation and maintenance
instructions.
WARNING: Some dust created by power sanding, sawing, grind-
ing, drilling, and other construction activities contains chemicals
known (to the State of California) to cause cancer, birth defects or
other reproductive harm. Some example of these chemicals are:
• lead from lead-based paints
• crystalline silica from bricks and cement and other masonry
products
• arsenic and chromium from chemically-treated lumber
Your risk from these exposures varies, depending on how often
you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety
equipment, al ways wear OSHA/MSHA/NIOSH approved, properly
fit ting face mask or res pi ra tor when us ing such tools.
When using air tools, basic safety precautions should always be followed to reduce the risk of of personal injury.
WARNING: This product contains chemicals, including lead,
known to the State of California to cause cancer, and birth
defects or other reproductive harm. Wash hands after handling.
SAVE THESE INSTRUCTION
DANGER: RISK OF EXPLOSION OR FIRE
WHAT CAN HAPPEN HOW TO PREVENT IT
• It is normal for electrical
contacts within the motor
and pressure switch to
spark.
• Always operate the compressor in a well ventilated area
free of combustible materials,
gasoline, or solvent vapors.
7
English
DANGER: RISK TO BREATHING (ASPHYXIATION)
WHAT CAN HAPPEN HOW TO PREVENT IT
• The compressed air directly
from your compressor is not
safe for breathing. The air
stream may contain carbon
monoxide, toxic vapors
or solid particles from the
air tank. Breathing these
contaminant's can cause
serious injury or death.
• Air obtained directly from the
compressor should never
be used to supply air for
human consumption. In order
to use air produced by this
compressor for breathing,
suitable filters and in-line
safety equipment must be
properly installed. In-line
filters and safety equipment
used in conjunction with the
compressor must be capable
of treating air to all applicable
local and federal codes prior to
human consumption.
• Sprayed materials such as
paint, paint solvents, paint
remover, insecticides and
weed killers, may contain
harmful vapors and poisons.
• Work in an area with good
cross ventilation. Read and
follow the safety instructions
provided on the label or safety
data sheets for the materials
you are spraying. Always use
certified safety equipment:
OSHA/MSHA/NIOSH
respiratory protection designed
for use with your specific
application.
• If electrical sparks from
compressor come into contact with flammable vapors,
they may ignite, causing fire
or explosion.
• If spraying flammable materials, locate compressor
at least 20' (6.1 m) away
from spray area. An additional length of hose may be
required.
• Store flammable materials in
a secure location away from
compressor.
• Restricting any of the compressor ventilation openings
will cause serious overheating and could cause fire.
• Never place objects against
or on top of compressor.
• Operate compressor in
an open area at least 12"
(30.5 cm) away from any
wall or obstruction that would
restrict the flow of fresh air to
the ventilation openings.
• Operate compressor in a
clean, dry well ventilated area.
Do not operate unit indoors or
in any confined area.
• Unattended operation of
this product could result in
personal injury or property
damage. To reduce the risk
of fire, do not allow the
compressor to operate unattended.
• Always remain in attendance
with the product when it is
operating.
• Always turn off and unplug
unit when not in use.

DANGER: RISK OF INJURY OR PROP ER TY DAMAGE WHEN
TRANSPORTING OR STORING
WHAT CAN HAPPEN HOW TO PREVENT IT
• Oil can leak or spill and could
result in fire or breathing
hazard; serious injury or
death can result. Oil leaks will
damage carpet, paint or other
surfaces in vehicles or trailers.
• Always place compressor
on a protective mat when
transporting to protect against
damage to vehicle from leaks.
Remove compressor from
vehicle immediately upon arrival
at your destination. Always keep
compressor level and never lie
on its side.
WARNING: RISK OF BURSTING
Air Tank: The air tank on your Air Compressor is designed and may
be UM coded (for units with air tanks greater than 6 inch diameter)
according to ASME Section VIII, Div. 1 rules. All pressure vessels
should be inspected once every two years. To find your state pressure
vessels inspector, look under the Division of Labor and Industries in
the government section of a phone book or call 1-800-4-D
EWALT for
assistance.
The following conditions could lead to a weakening of the air tank and
result in a violent air tank explosion:
WHAT CAN HAPPEN HOW TO PREVENT IT
• Failure to properly drain
condensed water from
air tank, causing rust and
thinning of the steel air tank.
• Drain air tank daily or after
each use. If air tank develops
a leak, replace it immediately
with a new air tank or replace
the entire compressor.
• Modifications or attempted
repairs to the air tank.
• Never drill into, weld, or make
any modifications to the air
tank or its attachments. Never
attempt to repair a damaged or
leaking air tank. Replace with a
new air tank.
• Unauthorized modifications
to the, pilot valve, safety valve
or any other components
which control air tank
pressure.
• The air tank is designed
to withstand specific
operating pressures. Never
make adjustments or parts
substitutions to alter the factory
set operating pressures.
Attachments & accessories:
• Exceeding the pressure
rating of air tools, spray guns,
air operated accessories,
tires and other inflatables can
cause them to explode or
fly apart, and could result in
serious injury.
• Follow the equipment
manufacturers
recommendation and never
exceed the maximum
allowable pressure rating
of attachments. Never use
compressor to inflate small
low pressure objects such
as children’s toys, footballs,
basketballs, etc.
9
English
Tires:
• Over inflation of tires could
result in serious injury and
property damage.
• Use a tire pressure gauge to
check the tires pressure before
each use and while inflating
tires; see the tire sidewall for
the correct tire pressure.
NOTE: Air tanks, compressors and
similar equipment used to inflate
tires can fill small tires similar to
these very rapidly. Adjust pressure
regulator on air supply to no more
than the rating of the tire pressure.
Add air in small increments and
frequently use the tire gauge to
prevent over inflation.
WARNING: RISK OF ELECTRICAL SHOCK
WHAT CAN HAPPEN HOW TO PREVENT IT
• This air compressor is
powered by electricity.
Like any other electrically
powered device, If it is not
used properly it may cause
electric shock.
• Never operate the
compressor outdoors when it
is raining or in wet conditions.
• Never operate compressor
with protective covers
removed or damaged.
• Repairs attempted by
unqualified personnel can
result in serious injury or
death by electrocution.
• Any electrical wiring or
repairs required on this
product should be performed
by a D
EWALT factory
service center or a D
EWALT
authorized service center in
accordance with national and
local electrical codes.
• Electrical Grounding:
Failure to provide adequate
grounding to this product
could result in serious injury
or death from electrocution.
See Grounding
Instructions under
Installation.
• Make sure the electrical circuit
to which the compressor is
connected provides proper
electrical grounding, correct
voltage and adequate fuse
protection.
WARNING: RISK FROM FLYING OBJECTS
WHAT CAN HAPPEN HOW TO PREVENT IT
• The compressed air stream
can cause soft tissue
damage to exposed skin and
can propel dirt, chips, loose
particles and small objects
at high speed, resulting in
property damage or personal
injury.
• Always wear certified safety
equipment: ANSI Z87.1 eye
protection (CAN/CSA Z94.3)
with side shields when using
the compressor.
• Never point any nozzle or
sprayer toward any part of
the body or at other people or
animals.
