DANGER:
WARNING:
WORK AREA SAFETY
1. Keep your work area clean and well lit.
Cluttered workbenches and dark areas invite
accidents.
2. Do not operate power tools in explosive
atmospheres, such as in the presence of
flammable liquids, gases, or dust. Power tools
create sparks which may ignite the dust or
fumes.
3. Keep bystanders, children, and visitors
away while operating a power tool.
Distractions can cause you to lose control.
4. Make your workshop childproof with padlocks
and master switches. Lock tools away when not
in use.
5. Make sure the work area has ample lighting
so you can see the work and that there are no
obstructions that will interfere with safe
operation before using your power tool.
PERSONAL SAFETY
SAFETY INSTRUCTIONS
1. Know your power tool. Read the operator’s
manual carefully. Learn the power tools
applications and limitations, as well as the
specific potential hazards related to this tool.
2. Stay alert, watch what you are doing, and
use common sense when operating a power
tool.
3. Do not use tool while tired or under the
influence of drugs, alcohol, or medication. A
moment of inattention while operating power
tools may result in serious personal injury.
4. Dress properly. Do not wear loose clothing
or jewelry. Pull back long hair. Keep your hair,
clothing, and gloves away from moving parts.
Air vents often cover moving parts and should
also be avoided. Loose clothing, jewelry, or
long hair can be caught in moving parts.
5. Avoid accidental starting. Be sure switch is
in “OFF” position before plugging in. Do not
carry tools with your finger on the switch.
Carrying tools with your finger on the switch or
plugging in tools that have the switch in the
“ON” position invites accidents.
6. Remove adjusting keys or wrenches
before turning the tool “ON.” A wrench that is
left attached to a rotating part of the tool may
result in personal injury.
7. Do no overreach. Keep proper footing
and balance at all times. Proper footing and
balance enables better control of the tool in
unexpected situations.
8. Always secure your work. Use clamps or a
vise to hold work when practical. It is safer
than using your hand and frees both hands to
operate tool.
9. Use safety equipment. Always wear eye
protection. Dust mask, non-skid safety shoes,
hard hat, or hearing protection must be used
for appropriate conditions.
10. Do not use on a ladder or unstable
support. Stable footing on a solid surface
enables better control of the tool in
unexpected situations.
TOOL USE AND CARE SAFETY
1. Always use clamps or other practical ways
to secure and support the work piece to a
stable platform. Holding the work by hand or
against your body is unstable and may lead to
loss of control.
2. Do not force the tool. Use the correct tool
and blade for your application. The correct tool
and blade will do the job better and safer at
the rate for which it is designed.
3. Do not use the tool if switch does not turn
it “ON” or “OFF.” Any tool that cannot be
controlled with the switch is dangerous and
must be repaired.
4. Disconnect the plug from the power source
before making any adjustments, changing
accessories, or storing the tool. Such
preventive safety measures reduce the risk of
starting the tool accidentally.
5. Never leave the tool running. Always turn it
off. Do not leave the tool until it comes to a
complete stop.
6. Store idle tools out of the reach of children
and other untrained persons. Tools are
dangerous in the hands of untrained users.
7. Maintain tools with care. Keep cutting tools
sharp and clean. Properly maintained tools
with sharp cutting edges are less likely to bind
and are easier to control.
8. Check for misalignment or binding of
moving parts, breakage of parts, and any
other condition that may affect the tool’s
operation. If damaged, have the tool serviced
WARNING:
BE SURE to read
and understand all instruction before
operating this power tool. Failure to follow
all instructions listed below may result in
electric shock, fire, and/or serious
personal injury.

provides optimum pressure. It features a 2 HP induction motor for quiet operation and
oil-free pump for long-lasting, reliable performance.
The procedures described in this manual are solely for this 29-gallon air compressor at a
maximum pressure of 150 PSI.
PRODUCT FEATURES
Electric Motor
The motor is used to power the pump. It is equipped with a thermal overload protector.
If the motor overheats for any reason, the thermal overload protector will shut it down in
order to prevent the motor from being damaged.
Air Compressor Pump
The pump compresses the air and discharges it into the tank via the piston that moves up
and down in the cylinder.
Safety Valve
This valve is used to prevent the compressor from building too much pressure. If the
pressure reaches the preset level of the motor, it will automatically pop open. You can also
pull the ring on the valve to open manually.
Pressure Switch
This switch turns the compressor on and off manually. ALWAYS set this switch to the OFF
position when the compressor is not being used and before unplugging.
Air Pressure Regulator
The regulator is used to adjust the pressure inside the line to the tool that is being used.
Turn the knob clockwise to increase the pressure and counter-clockwise to decrease the
pressure.
Tank Pressure Gauge
The gauge measures the pressure level of the air that is stored in the tank. It cannot be
adjusted by the operator and it does not indicate the pressure inside the line.
Tool Pressure Gauge
The gauge measures the regulated outlet pressure.
Air Outlet (Universal Coupler)
The outlet is connected to the 1/4” (6.4 mm) NPT air hose.
Air Tank Ball Valve
The ball valve is used to remove moisture from the air tank after the compressor is shut off.
Air Tank
The tank is where the compressed air is stored.
Power Cord
This compressor should be used on a nominal 120V grounded circuit. Use a power cord
that is equipped with a grounding plug. Verify that the compressor is plugged into an
outlet that has the same configuration as the plug. Do not use an adapter with this
compressor.
This air compressor is ideal for a wide range of jobsite applications. The 29-gallon design
