10. Do not attempt to pull or carry the air compressor by the hose.
11. Your tool may require more air consumption than this air compressor is capable of providing.
12. Never direct a jet of compressed air toward people or animals.
13. Protect your lungs. Wear a face or dust mask if the operation is dusty.
14. Do not use this air compressor to spray chemicals. Your lungs can be damaged by inhaling toxic fumes. A respirator may be necessary in dusty environments or when spraying paint.

ELECTRICAL SAFETY

1. 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.
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 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.
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.

Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician.

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

Improper electrical installation of this product may void its warranty and your fire insurance. Have circuit wiring performed by qualified personnel such as a licensed electrician who is familiar with the current national electrical code and any prevailing local electrical codes.

A qualified electrician needs to knows the following before wiring:

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

ELECTRICAL SAFETY (GROUNDING INSTRUCTIONS)

This product should be connected to a metallic, permanent wiring system, or an equipment-grounding terminal or lead on the product.

Air Distribution System

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.

FIGURE 1

NOTICE: Compressed air from oil lube air compressors will contain wa ter condensation and oil mist. Several drains, traps and filters will be needed to supply air without water (including aerosols) or oil to spray equipment, air tools and accessories requiring filtered air. Always read the ins truc tions for the air tools and accessories being used.

• Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air.
• If piping is over 100' (30.5 m) long, use the next larger size.
• Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.
• A flexible coupling is recommended to be installed between the globe valve/air discharge outlet and main air distribution line to allow for vibration.
• A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually too high for individual air driven tools.
• DO NOT install lubricators between the tank and any spray equipment, air tool or accessory requiring oil-free filtered air.
• Drain all traps, filters and dirt legs daily.

RISK OF BURSTING. ALWAYS use metal piping and fittings.

FIGURE 2

Part	Description
A	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.
B	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.
C	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).
D	Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank.
E	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.
F	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.
G	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.
H	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.
I	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: Place the Auto/Off switch in the "Off" position. Allow the motor to cool. Depress the red reset button on the motor. Place the Auto/Off switch in the "Auto" postion to restart the motor.

Operation

Draining the tank

(Figure 2, 4)

FIGURE 4

Risk of unsafe operation. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use eye protection [ANSI Z87.1 (CAN/ CSA Z94.3)] when draining as debris can be kicked up into face.

Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air flow noise is loud when draining.

Risk of bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.
NOTICE: Risk of property damage. Drain water from air tank may contain oil and rust which can cause stains.
NOTICE: All compressed air systems generate condensate that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains lubricating oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.
NOTICE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned, then reinstalled.

1. Set the Auto/Off switch (A, Figure 2) to "Off".
2. Slowly bleed the air from the air tank and air distribution system until tank pressure is approximately 20 psi.
3. Drain water from air tank by opening drain valve (F) on bottom of tank.
4. After the water has been drained, close the drain valve. The air compressor can now be stored.

Checking the safety valve

(Figure 5)

Do not tamper with the safety valve. Items loosened from this device could fly up and hit you. Failure to heed this warning could result in death or serious personal injury. The safety valve automatically releases air when the receiver pressure exceeds the preset maximum. Check the valve before each day of use by pulling the ring by hand.

If air leaks after releasing the safety valve ring or if the valve is stuck, do not use the air compressor until the safety valve has been replaced. Using the air compressor in this condition could result in serious personal injury.

FIGURE 5

1. Set the Auto/Off switch (A) to "On". and wait for the tank to fill. The compressor automatically shuts off when the pressure reaches the preset maximum.
2. Set the Auto/Off switch (A) to "Off".
3. Pull the ring on the safety valve (C) for 20 seconds to release the air.
4. Release the ring. Air stops escaping at about 20 psi. If air continues to escape after releasing the safety valve ring, discontinue use and seek service before using the air compressor again.

Before each start-up

(Figure 5)

Risk of unsafe operation. Firmly grasp air hose in hand when installing or disconnecting to prevent hose whip.

Risk of unsafe operation. Do not use damaged or worn accessories.

Risk of bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer's maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.

1. Place Auto/Off switch (A, Figure 5) to "Off".
2. Close the air discharge outlet.
3. Visually inspect air lines and fittings for leaks.
4. Check safety valve. See Checking the Safety Valve paragraph.
   
   Risk of unsafe operation. Compressed air from the unit may contain wa ter condensation and oil mist. Do not spray un filtered air at an item that could be damaged by moisture. Some air tools and accessories may require filtered air. Read the in struc tions for the air tools and accessories.
   NOTICE: A regulator MUST be installed when using accessories rated at less than 135 psi. The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect socket.

How to start

(Figure 2)

1. Turn the Auto/Off switch (A, Figure 2)) to "Auto" and allow tank pressure to build. Motor will stop when tank pressure reaches "cut-out" pressure.
2. When the tank pressure reaches "cutout" pressure open the air discharge valve.
   
   Risk of bursting. If any unusual noise or vibration is noticed, stop the air compressor immediately and have it checked by a trained service technician.
   NOTICE: When using regulator and other accessories refer to the manufacturers instructions.

Maintenance

Condensate forms in the tank when there is humidity in the air. Depending on the environmental conditions, drain the condensate daily and/or every hour. For instructions, see Draining the tank paragragh under Operation.
The safety valve automatically releases air when the receiver pressure exceeds the preset maximum.
Inspect the tank annually for rust, pin holes, or other imperfections that could cause it to become unsafe.
Avoid using solvents when cleaning plastic parts. Most plastics are susceptible to damage from various types of commercial solvents and may be damaged by their use.
Use clean cloths to remove dirt, dust, oil, grease, etc.

Do not allow brake fluids, gasoline, petroleum based products, etc., to come in contact with plastic parts. Chemicals can weaken or destroy plastic which, may result in serious personal injury.

When servicing, use only identical Husky replacement parts. Use of any other parts may create a hazard or cause product damage.

Always disconnect the air compressor from the power supply, release all pressure, and allow it to cool before cleaning or making repairs on the air compressor.

Oil

(Figure 6)
NOTICE: Risk of property damage. Use air compressor oil only. Multi-weight automotive engine oils like 10W30 should not be use in air compressors. They leave carbon deposits on critical components, thus reducing performance and compressor life.
NOTE: Use 30W compressor oil or a heavy duty SAE 30W, non-detergent, SF grade or better oil. DO NOT use multi-weight automotive engine oils, they will reduce compressor life. Under extreme winter condition use SAE-10 weight oil.
NOTE: Crankcase oil capacity is approximately 29 fluid ounces (857,6 ml).

FIGURE 6

Checking

1. The oil level should be to the middle of the sight glass (N).
2. If needed remove oil fill plug (L) and slowly add oil until it reaches the middle of the sight glass.

4. When proper belt tension is achieved, tighten all four motor mounting screws. Torque to 20-25 ft-lbs (27.1–33.9 Nm).
   NOTICE: Once the engine pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16" (1.6 mm) to prevent excessive belt wear. Verify the alignment by performing the following Pulley and Flywheel - Alignment.

Motor Pulley/Flywheel Alignment

(Figure 8)

FIGURE 8
The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16" (1.6 mm) to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps:

1. Turn air compressor off, lock out the power supply, and relieve all air pressure from the air tank.
2. Remove belt guard.
3. Place a straightedge (S) against the outside of the flywheel (P) and the motor drive pulley (R).
4. Measure the distance between the edge of the belt (Q) and the straightedge at points A1 and A2 in figure. The difference between measurements should be no more than 1/16" (1.6 mm).
5. If the difference is greater than 1/16" (1.6 mm) loosen the set screw holding the motor drive pulley (R) to the shaft and adjust the pulley's position on the shaft until the A1 and A2 measurements are within 1/16" (1.6 mm) of each other.
6. Tighten the motor drive pulley set screw.
7. Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 of Figure should appear to be equal. If they are not, loosen the setscrew of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment performed in step 2.
8. Retighten the motor drive pulley setscrew. Torque to 145–165 in lbs (16.4–20.3 Nm).
9. Reinstall belt guard.

Air compressors will also generate water condensation that will form in the tank and air lines. Install water and oil filter traps when needed. The Typical Compressed Air Distribution System provides a guideline. Contact a call Husky Customer Service for more information. If the tank or air lines have excessive water and/ or oil, bring the compressor to a service center.
