WORK AREA
GENERAL SAFETY RULES
Keep your work area clean and well lit. Cluttered benches and dark areas
invite accidents.
Do not operate power tools in an explosive atmosphere, such as in the presence of
flammable liquids, gases, or dust. Power tools create sparks that may ignite dust or
fumes.
Keep bystanders, children, and visitors away while operating a power tool.
Distractions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed.
ELECTRICAL SAFETY
Grounded tools must be plugged into a properly installed and grounded outlet in
accordance with all applicable codes and ordinances. Never remove the grounding prong or modify the plug in any way. Do not use adaptor plugs. Check with a
qualified electrician if you are in doubt as to whether the outlet is properly
grounded. If the tool should electrically malfunction or break down, grounding provides
a low-resistance path to carry electricity away from the user.
Double insulated tools are equipped with a polarized plug (one blade is wider than
the other). This plug will only fit into a polarized outlet one way. If the plug does
not fit fully into the outlet, reverse the plug. If it still does not fit, contact a
qualified electrician to install a polarized outlet. Do not change the plug in any
way. Double insulation
eliminates the need for the three-wire grounded power cord
and grounded power supply system.
Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is grounded.
Do not expose power tools to rain or wet conditions. Water entering a power tool will
increase the risk of electric shock.
Do not abuse the power cord. Never use the power cord to carry the tool or pull
the plug from an outlet. Keep the power cord away from heat, oil, sharp edges, or
moving parts. Replace damaged power cords immediately. Damaged power cords
increase the risk of electric shock.
When operating a power tool outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the risk of
electric shock.
PERSONAL SAFETY
Stay alert. Watch what you are doing, and use common sense when operating a
power tool. Do not use a power tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating a power tool may
result in serious personal injury.
Dress properly. Do not wear loose clothing or jewellery. Contain long hair.
Keep your hair, clothing, and gloves away from moving parts. Loose clothes,
jewellery, or long hair can get caught in moving parts.
9
GENERAL SAFETY RULES
Avoid accidental start-ups. be sure the power switch is off before plugging in the
tool. Carrying a power tool with your finger on the power switch or plugging in a power
tool with the power switch on invites accidents.
Remove adjusting keys or wrenches before turning the power tool on. A wrench or
a key that is left attached to a rotating part of the power tool may result in personal
injury.
Do not overreach. Keep proper footing and balance at all times. Proper footing and
balance enables better control of the power tool in unexpected situations.
Use safety equipment. Always wear eye protection. A dust mask, non-skid safety
shoes, a hard hat, and hearing protection must be used for appropriate conditions. Always
wear ANSI-approved safety goggles and a dust mask/respirator when using or performing
maintenance on this tool.
TOOL USE AND CARE
Use clamps (not included) or other practical ways to secure and support the
workpiece to a stable platform. Holding the work by hand or against your body is
unstable, and may lead to loss of control.
Do not force the tool. Use the correct tool for your application. The correct tool will
do the job better and safer at the rate for which it is designed. Do not force the tool, and
do not use the tool for a purpose for which it is not intended.
Do not use the power tool if the power switch does not turn it on or off. Any tool that
cannot be controlled with the power switch is dangerous, and must be replaced.
Disconnect the power cord 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.
Store idle tools out of reach of children and other untrained persons. Tools are
dangerous in the hands of untrained users. Keep children away from power tools.
Maintain tools with care. Properly maintained tools are less likely to bind, and are easier
to control. Do not use a damaged tool. Tag damaged tools “Do not use” until repaired.
Check for misalignment or binding of moving parts, broken parts, and any other
condition that may affect the tool’s operation. If damaged, have the tool serviced
before using. Many accidents are caused by poorly maintained tools.
Use only accessories that are recommended for your model by the manufacturer.
Accessories that may be suitable for one tool may become hazardous when used on
another tool.

GLOSSARY OF TERMS
Become familiar with these terms before operating the unit.
CFM: Cubic feet per minute.
SCFM: Standard cubic feet per minute; a unit of measure of air delivery.
PSI: Pounds per square inch ; a unit of measure of pressure.
Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use
your accessory. When the tank pressure drops to a certain level, the motor will restart
automatically. The pressure at which the motor automatically restarts is called "cut-in"
pressure.
Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in
the air tank begins to build. It builds to a certain pressure before the motor automatically
shuts off - protecting your air tank from pressure higher than its capacity. The pressure at
which the motor shuts off is called "cut-out" pressure.
Branch Circuit: Circuit carrying electricity from the electrical panel to the outlet.
DUTY CYCLE
Air compressors should be operated on not more than a 50% duty cycle. This means that
forcing an air compressor to pump air more than 50% of one hour is considered misuse,
because the air compressor is undersized for the required air demand. Maximum compressor
pumping time is 30 minutes per hour.

INSTALLATION
GROUNDING INSTRUCTIONS
DANGER! Risk of Electric Shock. In the event of a short circuit, grounding
reduces the risk of shock by providing an escape route for the electric current.
This air compressor must be properly grounded.
The portable air compressor is equipped with a cord that has a grounding wire with an
appropriate grounding plug (see following illustrations). The plug must be used with an
outlet that has been installed and grounded in accordance with all local codes and
ordinances.
1. The cord set and plug with this unit contains a grounding pin. This plug MUST be
used with a grounded outlet.
IMPORTANT: The outlet being used must be installed and grounded in accordance with
all local codes and ordinances.
2. Make sure the outlet being used has the same configuration as the grounded plug.
DO NOT USE AN ADAPTOR. (See illustration)
3. If these grounding instructions are not completely understood, or if in doubt as to
whether the compressor is properly grounded, have the installation checked by a
qualified electrician.
Risk of Electric Shock. IMPROPER GROUNDING CAN RESULT IN ELECTRIC
SHOCK. Do not modify the plug provided. If it does not fit the available outlet,
a correct outlet should be installed by a qualified electrician. Repairs to the cord
set or plug MUST be made by a qualified electrician.

INSTALLATION
EXTENSION CORDS
Grounded tools require a three-wire extension cord. Double-insulated tools can use
either a two- or three-wire extension cord.
You must use a heavier gauge extension cord as the distance from the supply outlet
increases. Using an extension cord with an inadequately wire size causes a serious drop
in voltage, resulting in loss of power and possible damage to the tool. (See Table A.)
The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14-gauge cord can carry a higher current than a 16-gauge cord. When using
more than one extension cord to make up the total length, make sure each cord contains
at least the minimum wire size required. (See Table A.)
If you are using one extension cord for more than one tool, add the nameplate amperages
and use the sum to determine the required minimum cord size.
If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate that it is acceptable for outdoor use.
Make sure your extension cord is properly wired and in good electrical condition.
Always replace a damaged extension cord or have it repaired by a qualified electrician
before using it.
Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

Follow these instructions once you are finished using the compressor for the day:
1. Pull out on the safety valve to release the remaining air pressure from the tool, and then
disconnect the air hose from the compressor.
2. Remove any moisture in the air tank by opening the drain valve. Retighten the drain valve
once all moisture has been removed.
3. WARNING! Allow the air compressor to completely cool, and then store the unit in a
clean, dry, safe location, out of reach of children.

OPERATION
USING THE TIRE GAUGE
Place the opening of the tire gauge on the valve stem of the tire, and hold it firmly in place
for at least 2 seconds. If necessary,check twice for accuracy.
The sidewall of your tire will specify the maximum PSI or KPA rating, but the pressure level
for everyday driving will be specified in your vehicle's owner's manual, and should be
followed. It is recommended that you review your vehicle's owner's manual for optimum tire
pressure by season, or contact your tire manufacturer for more details.
NOTE: Check tire condition and pressure at least once per month and before any long trip.
Never exceed the maximum cold tire inflation pressure shown on the tire sidewall. The tire
pressures should be checked when the tires are cold. On hot days, the pressures will be 4 to
8 psi (28 - 50 KPA) higher after high-speed driving.
USING THE TIRE CHUCK
1. Connect the tire chuck to the hose using PTFE tape on the threads. You may also attach the
tire chuck to a quick-connect male plug for quick and easy removal in the future.
2. Connect the hose to the compressor, and turn the switch to the ON position. Allow the
pressure to build up to the maximum pressure level in the tank.
3. Adjust the regulator pressure to MAXIMUM position. In maximum output pressure position
(135 PSI), the tire will fill up quicker and more accurately. However, it is extremely important to
monitor the air flow using the tire gauge as it is in process of being filled in order to ensure that
you do not overfill the tire.
NOTE: If maximum pressure is not used for compressor output when filling a tire, the tire may
not fill, because there may be a pressure lock between the tire and the hose, which is normal.
In light of this, always use maximum pressure from the compressor, and continue to monitor
the pressure with a gauge.
4. Place the tire chuck on the tire valve stem and press it firmly into place in order to prevent
air from leaking out of the tire.
5. Remove the tire chuck from the valve stem, and check the pressure using a tire gauge.
This process needs to be followed throughout the process of filling each tire in order to ensure
of accuracy and to prevent overfilling.

MAINTENANCE
1. WARNING! Make sure the power switch of the air compressor is in its “OFF” position, all
air pressure has been released from the unit, and the unit is unplugged from its electrical
outlet before performing any inspection, maintenance, or cleaning procedures or leaving
the unit unattended.
2. Before each use, inspect the general condition of the air compressor. Check for loose
screws, misalignment or binding of moving parts, cracked or broken parts, damaged
electrical wiring, loose air fittings, and any other condition that may affect the safe
operation of the compressor. If abnormal noise or vibration occurs, have the problem
corrected before further use. Do not use damaged equipment.
3. Purge the air tank of all air and moisture every day in order to prevent corrosion. To do
so, slowly and carefully unscrew the drain valve (no more than four threads) until the
compressed air and condensation begin to be released from the tank. Allow sufficient
time for all of the air and condensation to escape from the Tank, and then firmly
retighten the drain valve.
4. CAUTION! All maintenance, service, or repairs not mentioned in this manual must be
performed by a qualified service technician.
