CAUTION:

Drain the moisture from the tank on a daily basis. A clean, dry tank will help prevent corrosion.

Pull the tank safety valve ring daily to ensure that the valve is functioning properly, and to clear the valve of any possible obstructions.

To provide proper ventilation for cooling, the compressor must be kept a minimum of 12 inches (31 cm) from the nearest wall, in a well-ventilated area. Restricting any of the compressor ventilation openings will cause overheating and could cause fire, never place objects against or on top of compressor.

Fasten the compressor down securely if transporting is necessary. Pressure must be released from the tank before transporting.

Protect the air hose and interconnect cord from damage and puncture. Inspect them weekly for weak or worn spots, and replace if necessary.

Risk of electric shock or injury - Use indoors only.

On oil-lubed compressors, oil can leak or spill and could result in fire or breathing hazard. Oil leaks will damage paint, carpet or other surfaces in vehicles or trailers. Always place the compressor on a protective mat when transporting to protect against damage to vehicle from leaks. Remove compressor from vehicle immediately upon arrival at your destination.

To prevent damage to tank and compressor on stationary models, the tank must be shimmied so the pump base is level within 1/8" to distribute oil properly. All feet must be supported, shimmering where necessary, prior to attaching to the floor. Fasten all feet to floor. We also recommend the use of vibration pads (094-0137) under tank feet.

GLOSSARY OF TERMS

CFM: Cubic feet per minute; a unit of measure of air flow.

PSI: Pounds per square inch; a unit of measure of air pressure.

Cut-in pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to factory set low pressure point, the motor will restart automatically. The low pressure at which the motor automatically restarts is called "cut-in" pressure.

Cut-out pressure: When an air compressor is turned on and

begins to run, air pressure in the air tank begins to build. It builds to the factory set high pressure point before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called "cut-out" pressure.

Well-ventilated: Means of providing fresh air in exchange for dangerous exhaust or vapors.

Dedicated circuit: An electrical circuit reserved for the exclusive use of the air compressor.

OVERVIEW

BASIC AIR COMPRESSOR COMPONENTS

The basic components of the air compressor are the electric motor, pump, pressure switch and tank (see Fig. 1).

The electric motor (see A) powers the pump.

The pump (see B) compresses the air and discharges it into the tank.

The tank (see C) stores the compressed air.

The pressure switch (see D) shuts down the motor when the tank reaches a pre-set "cut-out" pressure. As compressed air is used and the tank drops to a pre-set "cut-in" pressure, the switch restarts the motor automatically, and the pump resumes compressing air.

ASSEMBLY

ASSEMBLING THE COMPRESSOR

This compressor was shipped with oil in the pump crankcase. Check oil before operating the air compressor, see Check Oil under Maintenance.

1. Unpack the air compressor. Inspect the unit for damage. If the unit has been damaged in transit, contact the carrier and complete a damage claim. Do this immediately because there are time limitations to damage claims.

The carton should contain:

• air compressor - operator/parts manual

• Check the compressor's serial label to ensure that you have received the model ordered, and that it has the required pressure rating for its intended use.

• Locate the compressor according to the following guidelines:

a. For optimum performance, locate the compressor close to the power panel, as specified in ELECTRICAL POWER REQUIREMENTS, and as close as possible to the place where the air will be used. This ensures maximum power to the compressor and maximum air pressure to the tool. If both of these conditions cannot be met, it is better to locate the compressor close to the power panel, and use a longer air hose or distribution line to reach the usage area.
b. The flywheel side of the compressor must be at least 12 inches (31 cm) from any wall or obstruction, in a clean, well-ventilated area, to ensure sufficient air

flow and cooling.

c. In cold climates, locate the compressor in a heated building. This will reduce problems with lubrication, motor starting and freezing of water condensation.
d. Remove the compressor from the shipping pallet and place it on the floor or a hard, level surface. The compressor must be level to ensure proper lubrication of the pump and good drainage of the moisture in the tank.

CAUTION: The shipping pallet is not designed as a base for an operating compressor. Operating the compressor while it is on the pallet will void your warranty.

e. To prevent damage to tank and pump, the tank must be shimmed so the pump is level within 1/8" per lineal foot

Fig. 2

1. Connect an air hose or distribution line (not included) to the compressor.

Air dryers and after coolers

An air dryer or aftercooler is installed directly in the air line.

To remove this moisture, run the main air line downhill to a moisture trap and drain. Air/water filters should also be installed in the positions shown.

Air pressure regulation

The air pressure gauge on the pressure switch measures air pressure inside the tank, not pressure in the air line. Install an air regulator in the drop line for each tool, to regulate air pressure to that tool. Never exceed the maximum pressure rating of the tool.

Air lubrication

Install an air lubricator only for those tools requiring lubrication. Do not use a lubricator for paint spraying or similar applications. The oil will contaminate the paint and ruin the job.

Shut-off valves

Install shut-off valves in each drop line, to isolate the tool and its accessories for servicing. You can also install a bypass line around an accessory.

Moisture removal and air filtration

As the air cools, moisture will condense in the lines. This moisture must be removed before it reaches the tool being used.

COMPRESSOR CONTROLS

Main Power Disconnect

Install a main power disconnect switch in the power line to the compressor, near the compressor's location. It is operated manually, but when it is in the ON position, the compressor will start up or shut down automatically based on air demand. ALWAYS operate this switch to OFF when the compressor is not being used.

Pressure switch (see A)

This switch turns on the compressor. It is operated manually, but when in the ON position, it allows the compressor to start up or shut down automatically, without warning, upon air demand. ALWAYS set this switch to OFF when the compressor is not being used.

WARNING: For your safety, tank pressure is preset within the switch and must never be tampered with.

This switch must not be adjusted by the operator; doing so will void the warranty. The pressure switch controls the level of air pressure in the tank by automatically starting and stopping the motor, as required to maintain the factory preset pressure level.

The pressure switch also automatically bleeds pressure from the pump head when the pump stops. This feature eliminates back pressure in the pump, ensuring easier starting. Tank Safety Valve (see B)

Used to allow tank pressure to escape into the atmosphere. If the pressure switch does not shut off the compressor at its "cutout" pressure setting, the safety valve will protect against high

pressure by releasing tank pressure at its factory set pressure (slightly higher than the pressure switch "cut-out" setting). To operate manually, pull the ring on the valve to relieve air pressure in the tank.

Pressure Release Valve (see C)

The pressure release valve (located on the bottom of the pressure switch), is designed to release compressed air from the compressor head and outlet tube when the compressor reaches "cut-out" or is shut off. The pressure 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 brief release after reaching "cut-out" pressure.

Tank Pressure Gauge (see D)

This gauge measures the pressure level of the air stored in the tank. It is not adjustable by the operator, and does not indicate line pressure.

ELECTRICAL POWER REQUIREMENTS

MOTOR RESET SWITCH

WARNING: Ensure that all guards and shrouds are in place before pressing the reset switch to restart the motor.

If the motor shuts down because of overload, wait 10-15 minutes so the motor can cool down, then press (NEVER force) the reset switch (see E) to restart the motor (see Fig.4).

ELECTRICAL WIRING

Refer to the air compressor's serial label for the unit's voltage and amperage requirements. Ensure that all wiring is done by a licensed electrician, in accordance with the National Electrical Code. Use electrical conduit to protect the wiring.

MAIN POWER PANEL

For best performance and reliable starting, the air compressor must be installed on a dedicated circuit, as close as possible to the electrical power panel. Provide circuit breaker or fuse protection at your main power panel. Use time delay fuses on the circuit, because the compressor will momentarily draw several times its specified amperage when first started.

MAIN POWER DISCONNECT SWITCH

Install a main power disconnect switch in the line from the panel to the compressor. The main power disconnect switch must be located near the compressor, for ease of use and safety. When turned OFF, the main power disconnect switch shuts off all

power to the compressor. When it is turned ON, the compressor will start and stop automatically, controlled by the pressure switch.

LOW VOLTAGE PROBLEMS

Low voltage will cause difficult starting or an overload. Low voltage can be caused by a low supply voltage from the local power company, other equipment running on the same line, or inadequate wiring. If any other electrical devices are drawing from the compressor's circuit, it may fail to start.

Low voltage to the compressor can be caused by a supply wire of insufficient gauge for the distance between the compressor and the power source. The longer the distance, the larger the wire gauge (lower the number) must be, to overcome the inherent voltage loss caused by the wire resistance. Refer to the National Electrical Code to determine proper wire size for your circuit.

If the wiring is not adequate, the input voltage will drop by 20 to 40 volts at startup. Low voltage or an overloaded circuit can result in sluggish starting that causes the circuit breaker to trip, especially in cold conditions.

GROUNDING INSTRUCTIONS

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

OPERATING INSTRUCTIONS

BREAK-IN OF THE PUMP

NOTE: The pump is shipped with break-in oil which should be changed after the first 8 hours of operation.

This unit starts automatically.

ALWAYS shut off the main power disconnect, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in

use. Do not use the unit with the shrouds or belt

guard removed. Serious injury could occur from contact with moving parts.

Proper belt tension and pulley alignment must be maintained for maximum drive efficiency and belt life. The correct tension exists if a deflection (see A) of 1 / 2 (13mm) occurs by placing 10 lbs. (4.6kg) of force see B) midway between the motor pulley and the pump flywheel (See Fig.8). This deflection can be adjusted by the following procedure. The pulley should be carefully aligned with the flywheel, and all setscrews should be kept tight.

1. Remove the front of the beltguard by removing the screws using a Torx T25 bit.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct deflection exists (A & B).
4. Retighten the motor mounting bolts to 130-180 in.-lbs.
5. Check to ensure that the tension remained correct
6. Reinstall the belt guard. All moving parts must be guarded.

WARNING:

This unit starts automatically.

ALWAYS shut off the main power disconnect, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in Do not use the unit with the shrouds or belt I removed. Serious injury could occur from act with moving parts.

MAINTENANCE

NOTE: Once the motor pulley has been moved from its factory set location, the grooves of the flywheel and pulley must be aligned to within 1/16 to prevent excessive belt wear.

To check pulley alignment, remove the belt guard and place a straightedge (see A) against the pump flywheel (see B) (See Fig. 9). Measure and record the distance from the straightedge to the edge of the drive belt at point C. Then measure the distance from the straightedge to the edge of the drive belt again at points D and E. Both distances should be the same as at point C. If D or E are different from C, there is a misalignment which must be corrected before the compressor is run. To correct a pulley misalignment, use the following procedure.

1. Remove the front of the belt guard by removing the screws using a Torx T25 bit.
2. Loosen the motor mounting bolts.
3. Loosen the setscrews on the motor pulley.
4. Align the motor pulley with the pump flywheel (C-D-E must be equal).
5. Retighten the motor pulley setscrews.
6. Adjust the proper belt tension.
7. Retighten the motor mounting bolts to 130-180 in.-lbs.
8. Reinstall the belt guard. All moving parts must be guarded.
