ING: RISK OF BURSTING

Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission published Release # 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent upon several factors, some of which include operating conditions, ambient conditions, proper installations, field modifications, and the level of maintenance. The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of the air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized air to suddenly and forcefully escape, posing risk of injury to consumers.
Your compressor air tank must be removed from service by the end of the year shown on your tank warning label. 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

ELECTRICAL SAFETY
Extension Cords
Using extension cords is not recommended. The use of extension cords will cause voltage to drop resulting in power loss to the motor and overheating.
Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed.
If an extension cord must be used, be sure to follow these guidelines:
- Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the air compressor's plug.
-
When using the air compressor at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the compressor will draw. An undersized extension cord will cause a drop in line voltage, resulting in a loss of power and causing the motor to overheat. Use the chart provided below to determine the minimum wire size required in an extension cord.
-
Only round jacketed cords listed by Underwriter's Laboratories (UL) should be used.

** Used on 12 gauge - 20 amp circuit.
Note: A.W.G. = American Wire Gauge
- When working with the air compressor outdoors, use an extension cord that is designed for outside use. This is indicated by the letters "W-A" on the cord's jacket.
- Before using an extension cord, inspect it for loose or exposed wires and cut or worn insulation.
WARNING: Keep the extension cord clear of the working area. Position the cord so that it will not get caught on lumber, tools, or other obstructions while you are working with a compressor. Failure to do so can result in serious personal injury.
WARNING: Check the extension cords before each damaged, replace immediately. Never use the air compressor with a damaged cord since touching the damaged area could cause electrical shock resulting in serious personal injury.
NOTE: Use longer air hoses instead of long extension cords. Your air compressor will run better and last longer.
Electrical Connection
- This air compressor is powered by a precision built electric motor. It should be connected to a power
supply that is 120 volts, 60 Hz, AC only (normal household current).
- Do not operate this compressor on direct current (DC). A substantial voltage drop will cause a loss of power and the motor will overheat. If the air compressor does not operate when plugged into an outlet, double check the power supply.
Speed and Wiring
- The no-load speed of the electric motor varies by model and specification. The motor speed is not constant and decreases under a load or with lower voltage. For voltage, the wiring in a shop is as important as the motor's horsepower rating.
- A line intended only for lights cannot properly carry a compressor motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one compressor may not be able to support two or three compressors.
Grounding Instructions
WARNING: Risk of electrical shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.
The portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug.
- The cord set and plug 16 with this unit contains a grounding pin 17. This plug MUST be used with a grounded outlet 18.

Oil-free Universal Motor
Your air compressor features permanently lubricated bearings.
Manual On/Off Power Switch
This switch is used to start or stop the air compressor. Moving the switch to the (ON) position will provide automatic power to the pressure switch which will allow the motor to start when the air tank pressure is below the factory set cut-in pressure. When in the (ON) position, the pressure switch stops the motor when the air tank pressure reaches the factory set cut-out pressure. Moving the switch to the (OFF) position will remove power from the motor and stop the air compressor.
Air intake filter
This filter is designed to clean air coming into the pump. To ensure the pump continually receives a clean, cool, dry air supply this filter must always be clean and ventilation opening free from obstructions.
Electric Motor & Air Compressor Pump
The motor is used to power the pump. The electric motor has a thermal overload protector. If the motor overheats for any reason, the thermal overload will cut off power, thus preventing the motor from being damaged. Wait until the motor is cool.
Air compressor pump: to compress air, the piston moves up and down in the cylinder. On the down stroke, air is drawn in through the air intake valve while the exhaust valve remains closed. On the upstroke, air is compressed, the intake valve
closes and compressed air is forced out through the exhaust valve, into the discharge line, through the check valve and into the air tank.
Safety Valve
This valve is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be modified in any way.
Air Tank Drain Valve
The drain valve is used to remove moisture from the air tank.
Air Tank Pressure Gauge
The tank pressure gauge indicates the pressure of the air in the tank.
Regulated Pressure Gauge
The current line pressure is displayed on the regulator pressure gauge. This pressure can be adjusted by rotating the pressure regulator knob.
Pressure Regulator Knob
Use the pressure regulator knob to adjust the amount of air being delivered through the hose.
The air pressure coming from the air tank is controlled by the regulator knob. Turn the pressure regulation knob clockwise to increase discharge pressure, and counterclockwise to decrease discharge pressure. Follow tool operating instructions for recommended pressure range.
Air Tank
The tank is used to store the compressed air.
Quick Coupler
The outlet is used to connect the 1/4 in. NPT air hose.
Overload Protector (not shown)
This air compressor is equipped with a thermal overload device which will turn the air compressor off automatically, if the air compressor becomes overheated. If the motor turns OFF repeatedly, check for the following possible causes first: Low Voltage from the outlet. Lack of proper ventilation or outside air or room temperature too high. Extension cord too long or wrong gauge wire used.

Pneumatic tool (NOT INCLUDED) Male quick- connect plug Air hose with quick coupler fitting (NOT INCLUDED)- Connect the power cord to the power supply.
- Turn the ON/OFF switch ① to the ON (I) position.
- Rotate the pressure regulator knob ④ to the desired line pressure. Turning the knob clockwise increases air pressure at the outlet; turning the knob counterclockwise reduces air pressure at the outlet.
NOTE: Before connecting or disconnecting air tools, turn the regulator knob counterclockwise to stop the flow of air. - Following all safety precautions in this manual and the manufacturer's instructions in the air tool manual, you may now use your air-powered tool.
- If using an inflation accessory with a quick-connect fitting, control the amount of air flow with the pressure regulator knob. Turning the knob fully counterclockwise will completely stop the flow of air.
NOTE: Always use the minimum amount of pressure necessary for your application. Using a higher pressure than needed will drain air from the tank more rapidly and cause the unit to cycle on more frequently. - When finished, always drain the tank and unplug the unit. Never leave the unit plugged in and/or running unattended.
WARNING: Check the air tool manual to ensure correct air pressure regulator setting for optimum operation of your air tools. If you are using an air tool not originally included in the package contents list (not necessarily supplied with the air compressor model you have purchased), your tool may require more air consumption than this air compressor is designed to supply. Always read your air tool owner's manual to match the correct air supply to your air tool to avoid damage to the tool or risk of personal injury.
Duty cycle:
To avoid overheating of the electric motor, this compressor is designed for intermittent operation as indicated on the dataplate: 5 minutes ON / 5 minutes OFF. This indication is equivalent to a S3 50% duty cycle: if the compressor run time exceeds 5 minutes in any 10 minute period, then the application requires more air than the compressor is capable to deliver.
ENGLISH
