These chemicals may include (but are not limitedto) the following:
• 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, always wear
MSHA/NIOSH approved, properly fitting face masks or respirators when
using such tools.
Always follow basic safety precautions when using air tools to reduce the
risk of personal injury.
Bursting
Rust can weaken the tank. Drain the condensed water from the tank after
each use to reduce rusting. If a leak is detected in the tank, replace the tank
immediately. Do not weld, drill or modify the air tank of this compressor.
Welding or modifications on the air compressor tank can severely impair
tank strength and cause an extremely hazardous condition. Welding or
modifying the tank in any manner will void the warranty.
Check the manufacturer's maximum pressure rating for air tools and
accessories. Compressor outlet pressure must be regulated so as to never
exceed the maximum pressure rating of the tool. Relieve all pressure
through the hose before attaching or removing accessories.
Do not adjust the pressure switch or relief valve for any reason. Doing so
voids all warranties. They have been preset at the factory for the maximum
pressure of this unit. Personal injury and/or property damage may result if
the pressure switch or the relief valve are tampered with.
Do not use plastic or pvc pipe for compressed air. Use only galvanized steel
pipe and fittings for compressed air distribution lines.

HazardWarnings(cont'd)
Riskof Eyeor HeadInjury
What could happen:
• Air powered equipment and power tools are capable
of propelling materials such as fasteners, metal chips,
saw dust, and other debris at high speed, which could
result in serious eye injury.
• Compressed air can be hazardous. The air stream
can cause injury to soft tissue areas such as eyes,
ears, etc. Particles or objects propelled by the stream
can cause injury.
• Tool attachments can become loose or break and fly
apart propelling particles at the operator and others in
the work area.
How to prevent it:
• Always wear ANSI approved Z87.1 safety glasses with side shields.
• Never leave operating tool unattended. Disconnect air hose when tool is
not in use.
For additional protection, use an approved face shield in addition to
safety glasses.
Make sure that any attachments are securely assembled.
Never point any nozzle or sprayer toward a person or any part of the
body. Equipment can cause serious injury if the spray penetrates the
skin.

HazardWarnings(cont'd)
Riskof Fireor Explosion
What could happen:
• Abrasive toolssuch as sanders and grinders, rotating
tools such as drills, and impact tools such as nailers,
staplers, wrenches, hammers, and reciprocating saws
are capable of generating sparks which could result in
ignition of flammable materials.
• It is normal for the compressor motor and pressure
switch to produce sparks while operating. If sparks
come into contact with vapors from gasoline or other
solvents, they may ignite, causing fire or explosion.
• Exceeding the maximum pressure rating of tools or
accessories could cause an explosion resulting in
serious injury.
How to prevent it:
Never operate tools near flammable substances such as gasoline,
cleaning solvents, etc.
Work in a clean, well ventilated area free of combustible materials.
Never use oxygen, carbon dioxide or other bottled gases as a power
source for air tools.
• Use compressed air regulated to maximum pressure at or below the
rated pressure of any attachments.
• Never connect to an air source that is capable of exceeding 200 psi.
• Always verify prior to using the tool that the air source has been
adjusted to the rated air pressure range.
• Never spray flammable liquids in a confined area. Do not spray where
sparks or flame are present.
• Do not smoke while spraying.
• Keep compressor as far from spray area as possible.

Riskof HearingLoss
What could happen:
• Long term exposure to noise produced from the
operation of air tools can lead to permanent hearing
loss.
How to prevent it:
• Always wear ANSI $3.19 hearing protection when using a compressor.
What could happen:
HazardRiSkto Breathing/Inhalation
• Abrasive tools such as grinders, sanders, and cut-off
tools generate dust and abrasive materials which can
be harmful to human lungs and respiratory system.
• Some materials such as adhesives and tar contain chemicals whose
vapors could cause serious injury with prolonged exposure.
How to prevent it:
• Always wear MSHA/NIOSH approved, properly fitting face mask or
respirator when using such tools. Read all instructions and be sure that
your respirator mask will protect you.
• Always work in a clean, dry, well ventilated area.
• Never directly inhale the compressed air produced by a compressor. It is
not suitable for breathing purposes.
• Be certain to read all labels when you are spraying paints or toxic
materials, and follow the safety instructions.

Riskof Injury
What could happen:
• Tools leftunattended, or withthe air hose attached
can be activated by unauthorized persons leading to
their injuryand/or injury to others.
• Air toolscan propelfasteners or other materials
throughoutthe work area.
• A wrench orkey that is leftattached to a rotatingpart
of the tool increases the riskof personal injury.
• Using inflatornozzles for duster applications can
cause serious injury.
• Air tools can become activated by accident during
maintenance or tool changes.
• Air tools can cause the work-piece to move upon
contact leading to injury.
• Loss of control of the tool can lead to injury to self or
others.
Poor quality, improper, or damaged tools such as
grinding wheels, chisels, sockets, drills, nailers,
staplers, etc., can fly apart during operation,
propelling, particles throughout the work area causing
senous injury.
• Fasteners could ricochet or be propelled causing
serious injury or property damage.
• Improperly maintained tools and accessories can
cause serious injury.
There is a risk of bursting if the tool is damaged.
The compressor unit starts automatically. Serious
injury could occur from contact with moving parts.
