of electric shock if your body is grounded.

2. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

3. Replace damaged cords/wiring immediately. Damaged cords/wiring increase the risk of electric shock.

ELECTRICAL SAFETY (ELECTRICAL CONNECTION)

1. This air compressor is powered by a precision built electric motor. It should be connected to a power supply that is 240volts, 60 Hz, AC only (normal household current).

2. Do not operate this tool 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.

ELECTRICAL SAFETY (SPEED AND WIRING)

1. The no-load speed of the electric motor varies by model and specication. 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.

2. A line intended only for lights cannot properly carry a power tool motor. Wire that is heavy enough for a short distance will be too light for a greater distance. A line that can support one power tool may not be able to support two or three tools.

WARNING: Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualied electrician.

ELECTRICAL SAFETY

1. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk

Safety Information (continued)

WARNING: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.

CAUTION: Improper electrical

installation of this product may void its warranty and your re insurance. Have circuit wiring

such as a licensed electrician

performed by qualied personnel

who is familiar with the current national electrical code and any prevailing local electrical codes.

A qualied electrician needs to know the following before wiring:

1. The amperage rating of the electrical box should be adequate. Refer to the Specications for this information.

Air Distribution System

WARNING: Risk of bursting. Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribution lines.

Figure 1 represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system.

NOTICE: Compressed air from oil lube air compressors will contain wa ter condensation and oil mist. Several drains, traps and lters will be needed to supply air without water (including aerosols) or oil to spray equipment, air tools and accessories requiring ltered air. Always read the in struc tions for the air tools and accessories

pts-205109-051012, pts-2053019-053012, pts-206067-060612

being used.

2. The supply line should have the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information.

NOTICE: The wiring used must be rated for the motor nameplate voltage, plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire size, and maximum wire run; undersize wire causes high amp draw and overheating to the motor.

Auto(I)/Off(0) Switch: Turn this switch in the “Auto (I)” position to provide automatic power to the pressure switch and “Off (O)” to remove power at the end of each use.

Pressure Switch: The pressure switch automatically starts the motor when the air tank pressure drops below the factory set “cut-in” pressure. It stops the motor when the air tank pressure reaches the factory set “cut-out” pressure.

Safety Valve: If the pressure switch does not shut off the air compressor at its “cut-out” pressure setting, the safety valve will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch “cut-out” setting).

Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.

Air Compressor Pump: Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.

Package Contents (continued)

Part Description

Drain Valve: The drain valve is located at the base of the air tank and is used to

drain condensation at the end of each use. Check Valve: When the air compressor is operating, the check valve is “open”,

allowing compressed air to enter the air tank. When the air compressor reaches

“cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank.

Pressure Release Valve: The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches “cut-out”

pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running or after the unit reaches “cut-out” pressure.

Motor Overload Reset: This motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart:

1. Place the Auto/Off switch in the “Off” position.

2. Allow the motor to cool.

3. Depress the red reset button on the motor.

4. Place the Auto/Off switch in the “Auto” postion to restart the motor.

1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.

2. Apply a soap solution to all air line ttings and connections/piping.

3. Correct any leaks found.

NOTICE: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.

Troubleshooting (continued)

Oil and/or moisture in tank and/or air lines

Water condensation Oil blow-by in pump

It is normal for oil lube air

compressor pumps to release some oil into the tank and air lines. Air compressors will also generate water condensation that will form in the tank and air lines. Install water and oil lter traps when needed. The Typical Compressed Air Distribution System provides a guideline. Contact a call Husky Customer Service for more information.

IMPORTANT: If the tank or air

lines have excessive water and/ or oil, bring the compressor to a service center.
