BEFORE USING THIS PRODUCT
IMPORTANT SAFETY PRECAUTIONS
WARNING Improper operation or maintenance of this product could result in serious injury and/or property
damage. Read and understand all of the warnings and safety instructions provided before using this equipment.
SAVE ALL INSTRUCTIONS
The air compressor should be operated on a dedicated 15-amp circuit. If the circuit does not have 15 free amps
available, a larger circuit must be used. Always use more air hose before utilizing extension cords. Low voltage
could cause damage to the motor.
■Risk of Moving Parts. If the air compressor is in operation, all guards and covers should be attached or installed
correctly. If any guard or cover has been damaged, do not operate the equipment until the proper personnel have
correctly repaired the equipment. The power cord should be free of any moving parts, twisting and/or crimping while in
use and while in storage.
■Risk of Burns. There are surfaces on your air compressor that while in operation and thereafter can cause serious
burns if touched. The equipment should be allowed time to cool before any maintenance is attempted. Items such
as the compressor pump and the outlet tube are normally hot during and after operation.
■Risk of Falling. Operation of the air compressor should always be in a position that is stable. Never use the air
compressor on a rooftop or elevated position that could allow the unit to fall or be tipped over. Use additional air hose
for elevated jobs.
■Risk from Flying Objects. Always wear approved safety glasses with side shields when the air compressor is in use.
Turn off the air compressor and drain the air tank before performing any type of maintenance or disassembly of the
hoses or fittings. Never point any nozzle or sprayer toward any part of the body or at other people or animals.
■Risk to Breathing. Avoid using the air compressor in confined areas. Always have adequate space (30 cm) on all
sides of the air compressor. Also keep children, pets, and others out of the area of operation. This air compressor does
not provide breathable air for anyone or any auxiliary breathing device. Spraying material will always need to be in
another area away from the air compressor to not allow intake air to damage the air compressor filter.

other function.

PARTS & FEATURES
Drain Valve: Used to drain condensation from the air tank. Located at bottom of tank.
Motor Thermal Overload: The motor has an automatic thermal overload protector. If the motor overheats, this protector will shut off
the motor. The motor must be allowed 30 minutes to cool before restarting.
Quick Connect: Offers a quick release feature for attaching and removing the air hose.
Oil-Free Pump: Oil free direct driven pump that compresses air, which is distributed to the tank.
Tank Safety Valve: Used to allow excess tank pressure to escape into the atmosphere. This valve should only open when the tank
pressure is above the maximum rated pressure.
Outlet Pressure Gauge: Indicates the outgoing air pressure to the tool and is controlled by the regulator.
Tank Pressure Gauge: Indicates the reserve air pressure in the tank.
Regulator: The regulator controls the air pressure coming from the air tank. To increase the pressure, turn the knob clockwise and to
decrease the pressure turn the knob counterclockwise.
INSTALLATION & ASSEMBLY
Lubrication and Oil This compressor requires no lubrication or oiling. No break in procedure is required by the user.
This product is factory tested to ensure proper operation and performance.
Location of the Air Compressor The air compressor should always be located in a clean, dry, and well-ventilated
environment. The unit should have at minimum, 30cm of space on each side. The air filter intake should be free of
any debris or obstructions. Check the air filter on a daily basis to be sure it is clean and in working order.
Extension Cords Use only a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot receptacle that will
accept the plug on the product. Make sure your extension cord is in good condition. When using an extension cord, be
sure to use one heavy enough to carry the current your product will draw. Cords must not exceed 25 feet and No. 12
AWG size must be used. An undersized cord will cause a drop in line voltage resulting in loss of power and
overheating.
Grounding Instructions This product should be grounded. In the event of an
electrical short circuit, grounding reduces the risk of electric shock by
providing an escape wire for the electric current. This product is equipped with
a cord having a grounding wire with an appropriate grounding plug. The plug
must be plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances. Check with a qualified
electrician or service personnel if these instructions are not completely
understood or if in doubt as to whether the tool is properly grounded.

OPERATION PROCEDURES
Daily Start-Up Procedures
1. Set the On/Off switch to the off position.
2. Check the air compressor visually for any damage or obstruction.
3. Close the drain valve.
4. Plug the power cord into the proper receptacle.
5. Turn the On/Off switch to the On position and the compressor should start and build air pressure in the tank to cut-out
pressure and then shut off automatically.
6. Adjust the regulator to a PSI setting that is recommended for your application.
7. The air compressor is now ready for use.
WARNING Improper installation of the grounding plug can result in a risk of electric shock. If repair or
replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal. The wire
with insulation having an outer surface that is green with or without yellow stripes is the grounding wire. Check with a
qualified electrician or serviceman if the grounding instructions are not completely understood, or if in doubt as to
whether the product is properly grounded. Do not modify the plug provided; if it will not fit the outlet, have the proper
outlet installed by a qualified electrician.
Daily Shut-Down Procedures
1. Set the Auto-On/Off lever to the Off position.
2. Unplug the power cord from the receptacle.
3. Set the outlet pressure to zero on the regulator.
4. Remove any air tools or accessories.
5. Open the drain valve allowing air to bleed from the tank. After all of the air has bled from the tank, close the drain
valve to prevent debris buildup in the valve.
Water that remains in the tank during storage will corrode and weaken the air tank, which could cause the tank to
rupture. To avoid serious injury, be sure to drain the tank after each use or daily.
CAUTION When draining the tank, always use ear and eye protection. Drain the tank in a suitable location;
condensation will be present in most cases of draining.

CAUTION To ensure efficient operation and longer life of the air compressor unit, a routine maintenance
schedule should be followed. The following schedule is geared toward a consumer whose compressor is used in a
normal working environment on a daily basis. If necessary, the schedule should be modified to suit the condition under
which your compressor is used. The modifications will depend upon the hours of operation and the working
environment. Air compressors used in an extremely dirty and/or hostile environment will require a greater frequency of
all maintenance checks.

STORAGE
For storing the air compressor, be sure to do the following:
1. Turn the unit off and unplug the power cord from the receptacle.
2. Remove all air hoses, accessories, and air tools from the air compressor.
3. Perform the daily maintenance schedule.
4. Open the drain valve to bleed all air from the tank.
5. Close the drain valve.
6. Store the air compressor in a clean and dry location.
WARNING The air compressor should be turned off and unplugged from the power source before any
maintenance is performed as well as the air bled from the tank and the unit allowed time to cool. Personal injuries
could occur from moving parts, electrical sources, compressed air or hot surfaces.
TROUBLE SHOOTING GUIDE
The air compressor should be turned off and unplugged from the power source before any maintenance is performed
as well as the air bled from the tank and the unit allowed time to cool. Personal injuries could occur from moving
parts, electrical sources, compressed air, or hot surfaces.
Problem Possible Correction
Air leaks at the check valve or
at the pressure relief valve.
A defective check valve results in a constant air leak at the pressure release valve
when there is pressure in the tank and the compressor is shut off. Drain the tank, then
remove and clean or replace the check valve.
Air leaks between head and
cylinder.
Be sure of proper torque on head bolts. If leak remains, contact a service technician.
Air leak from safety valve.
Operate the safety valve manually by pulling on the ring. If the valve continues to leak
when in the closed position, it should be replaced.
Pressure reading on the
regulated pressure gauge
drops when an accessory is
used.
If there is an excessive amount of pressure drop when the accessory is used, replace
the regulator.
NOTE:
Adjust the regulated pressure under flow conditions (while accessory is being used). It
is normal for the gauge to show minimal pressure loss during initial use of the tool.
Excessive tank pressure.
Move the Auto-On/Off lever to the Off position. If the unit doesn't shut off, unplug it from
the power source and contact a service technician.
Motor will not start.
Make sure power cord is plugged in and the switch is on. Inspect for the proper size
fuse in your circuit box. If the fuse was tripped reset it and restart the unit. If repeated
tripping occurs, replace the check valve or contact your service technician.
Excessive moisture in the
discharge air.
Remove the water in the tank by draining after each use. High humidity environments
will cause excessive condensation. Utilize water filters on your air line.
NOTE:
Water condensation is not caused by compressor malfunction. Be sure the
compressor's air output is greater than your tool's air consumption rate.
Air leaks from the tank body
or tank welds.
Never drill into weld or otherwise modify the air tank or it will weaken. The tank can
rupture or explode. Compressor cannot be repaired. Discontinue use of the air
compressor.
