ELECTRICAL SAFETY (EXTENSION CORDS)

□□ Use only 3-wire extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the product’s plug. Make sure your extension

cord is not damaged. When using a power tool at a considerable distance from the power source, use an extension cord heavy enough to carry the current that the product 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.

□□ Only use 50 feet or less, round jacketed cords listed by Underwriter’s Laboratories (UL).

□□ When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

		Ampere rating
		(on air compressor data plate)
		14-16
	Cord	Wire Size (AWG)
	Length
	25 ft.	16
	50 ft.	12

Used on 12 gauge - 20 amp circuit.

NOTE: AWG=American Wire Gauge

ELECTRICAL SAFETY (ELECTRICAL CONNECTION)

□□ This air compressor is powered by a precision built electric motor. It should be connected to a power supply that is 230 volts, 60 Hz, AC only (normal household current).

□□ 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.

WARNING: When using an extension cord, keep it 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 power tool. Failure to do so can result in serious personal injury.

WARNING: Check extension cords before each use. If 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.

WARNING: Improperly connecting the equipmentgrounding conductor can result in a risk of electrical shock.

CAUTION: 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.

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

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

NOTICE: Use longer air hoses instead of long extension cords. Your air compressor will run better and last longer.

Part Description

AAUTO(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

Bbelow 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

Csetting, 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).

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

EAir 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.

FDrain 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

Gto 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

Hthe 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.

I1. 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.

JCompressor Feet: The compressor feet are used to stabilize the compressor and used as brackets when mounting to the floor.

KBelt Guard: The belt guard is a protective enclosure for moving parts.

LPump Oil Fill: The pump oil fill is used to add oil to the crankcase.

MPump Oil Drain: The pump oil drain is used to purge old oil from the pump. Loosening the drain plug will allow oil to exit the pump crankcase.

NPump Oil Sight Glass: The pump oil sight is a visual identifier for oil level in the crank case.

OMotor: The motor is the drive component powered by electricity to rotate the pump by a belt pulley system.

PAir Outlet: The air outlet is connection point to provide useable air for the tools.

PLACEMENT OF THE AIR COMPRESSOR

Pre-Operation (continued)

AIR DISTRIBUTION SYSTEM

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

□□ Use a pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air.

□□ If the piping is over 100 ft. (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 the underground lines are covered to make sure all the pipe joints are free of leaks.

□□ A flexible coupling is recommended to be installed between the globe valve/air discharge outlet and the 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 the 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.

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.

WARNING: Risk of bursting. Always use metal piping and fittings.

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

WARNING: 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.
WARNING: Risk from noise. Use ear protection (ANSI
S12.6 (S3.19), as air flow noise is loud when draining.
WARNING: 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.
NOTE: All compressed air systems generate condensate
that accumulates in any drain point (e.g., tanks, filter,
after-coolers, 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.
NOTE: If drain valve is plugged, release all air pressure.
The valve can then be removed, cleaned, then reinstalled.
NOTE: Risk of property damage. Drained water from the
air tank may contain oil and rust which can cause stains.

Maintenance

GENERAL 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.

□□ 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.

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

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

WARNING: Do not at any time let brake fluids, gasoline, petroleum-based products, penetrating oils, etc., come

in contact with plastic parts. Chemicals can damage, weaken or destroy plastic which may result in serious personal injury. Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommended using this tool for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the tool using compressed air.

ADJUSTING THE BELT TENSION

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 in. (1.6 mm) to prevent excessive belt wear. Verify the alignment by performing the MOTOR PULLY/FLYWEEL ALIGNMENT on the following page.

□□ Slide the motor into the original position, and line the motor up with the mark made earlier on the saddle.

□□ Tighten the two outside motor mounting screws enough to hold the motor in place for checking the pulley and flywheel alignment.

□□ The belt should deflect 3/16 in. (4.8 mm) at midway between the pulley and the flywheel when a five-pound (2.26 kg.) weight is applied at the midway point.

□□ When proper belt tension is achieved, tighten all four motor mounting screws. Torque to 20-25 ft-lbs (27.1–33.9 Nm).

MOTOR PULLEY/FLYWHEEL ALIGNMENT

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

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

□□ Remove belt guard.

□□ Place a straightedge (4) against the outside of the flywheel (1) and the motor drive pulley (3).

□□ Measure the distance between the edge of the belt (2) and the straightedge at points A1 and A2. The difference between measurements should be no more than 1/16 in. (1.6 mm).

□□ If the difference is greater than 1/16 in. (1.6 mm), loosen the set screw holding the motor drive pulley (3) to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measurements are within 1/16 in. (1.6 mm) of each other.

□□ Tighten the motor drive pulley set screw.

□□ Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. The points (B1 and B2) 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 previously.

□□ Retighten the motor drive pulley setscrew. Torque to 145–165 in.-lbs. (16.4–20.3 Nm).

□□ Reinstall the belt guard.

AIR COMPRESSOR INTAKE AND EXHAUST VALVES

Once a year bring the compressor to a service center and have a trained service technician check the air compressor pump intake and exhaust valves.

INSPECT AIR LINES AND FITTINGS FOR

LEAKS

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

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

□□ Apply a soap solution to all air line fittings and connections/piping.

□□ Correct any leaks found.

TORQUING THE AIR COMPRESSOR HEAD BOLTS

The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation.

□□ Torque to 14–16 ft. lbs. (19.0–21.7 Nm).

Care and Cleaning

□□ Drain the air tank of moisture after operation.

□□ When not in use, store the compressor in a cool, dry place.

□□ Disconnect the air hose and hang open ends down to allow any moisture to drain.

□□ Protect the electrical cord and air hose from damage (such as being stepped on or run over).
