CONSIGNES DE SECURITE

Read and understand all safety precautions in this manual before operating. Failure to comply with instructions in this manual could result in personal injury, property damage, and/or voiding of your warranty. The manufacturer WILL NOT be liable for any damage because of failure to follow these instructions.

1. RISK OF FIRE OR EXPLOSION. Never spray flammable liquids in a confined

area. It is normal for the motor and pressure switch to produce sparks while operating. If sparks come into contact with vapors from gasoline or other solvents, they may ignite, causing fire or explosion. Always operate the compressor in a well-ventilated area. Do not smoke while spraying. Do not spray where sparks or flame are present. Keep compressor as far from spray area as possible.

1. RISK OF BURSTING. Do not weld, drill or modify the air tank of this compressor. Welding or modifications on the air

compressor tank can severely impair tank strength and cause an extremely hazardous condition. Welding or modifying the tank in any manner will void the warranty.

1. RISK OF ELECTRICAL SHOCK. Never use an electric air compressor outdoors when it is raining or on a wet surface, as it may cause an electric

shock.

1. RISK OF INJURY. 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.

1. RISK OF BURSTING. Check the manufacturer's maximum pressure rating for air tools and accessories. Compressor outlet pressure must be regulated so

as to never exceed the maximum pressure rating of the tool. Relieve all pressure through the hose before attaching or removing accessories.

1. RISK OF BURNS. High temperatures are generated by the pump and manifold. To prevent burns or other injuries,

DO NOT touch the pump, manifold or transfer tube while the pump is running. Allow them to cool before handling or servicing. Keep children away from the compressor at all times.

1. RISK TO BREATHING. Be certain to read all labels when you are spraying paints or toxic materials, and follow the safety instructions. Use a respirator

mask if there is a chance of inhaling anything you are spraying. Read all instructions and be sure that your respirator mask will protect you. Never directly inhale the compressed air produced by a compressor. It is not suitable for breathing purposes.

8. RISK OF EYE INJURY.

Always wear ANSI Z87.1 approved safety goggles when using an air compressor. Never point any nozzle or sprayer toward a person or any part of the body. Equipment can cause serious injury if the spray penetrates the skin.

1. RISK OF BURSTING. Do not adjust the relief valve for any reason. Doing so voids all warranties. The relief valve has

been pre-set at the factory for the maximum pressure of this unit. Personal injury and/or property damage may result if the relief valve is tampered with.

1. RISK OF BURSTING. Do not use plastic or pvc pipe for compressed air. Use only gvanized steel pipe and fittings for compressed air distribution

lines.

11. RISK OF BURSTING.

or after each use. If air tank develops a leak, replace it immediately with a new air tank or replace the entire compressor.

1. RISK TO HEARING. Always wear hearing protection when using an air compressor. Failure to do so may result in hearing loss.

DANGER

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

• Failure to properly drain condensed water from air tank, causing rust and thinning of the steel air tank.

• Drain air tank daily or after each use. If air tank develops a leak, replace it immediately with a new air tank or replace the entire compressor.

• Modifications or attempted repairs to the air tank.

• Never drill into, weld or make any modifications to the air tank or its attachments. Never attempt to repair a damaged or leaking air tank. Replace with a new air tank.

• Unauthorized modifications to the safety valve, or any other components which control air tank pressure.

• The air tank is designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures.

WARNING

1. Drain the moisture from the tank on a daily basis. A clean, dry tank will help prevent corrosion.
2. Pull the pressure relief valve ring daily to ensure that the valve is functioning properly, and to clear the valve of any possible obstructions.
3. 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.
4. To prevent damage to tank and compressor on stationary models, the tank must be shimmed 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.

1. Fasten the compressor down securely if transporting is necessary. Pressure must be released from the tank before transporting.
2. Protect the air hose from damage and puncture. Inspect them weekly for weak or worn spots, and replace if necessary.
3. To reduce the risk of electric shock, do not expose to rain. Store indoors.

BASIC AIR COMPRESSOR COMPONENTS

The basic components of the air compressor are the electric motor, Thermal Overload Protection System (TOPS), pump, and receiver (tank).

The electric motor (see A) powers the pump.

TOPS senses both temperature and current, providing more complete motor overload protection than a magnetic starter, which senses only current. If TOPS senses an overload condition, it will automatically shutdown the compressor. Allow 10-15 minutes for the unit to cool down, then press the reset button on the motor to restart the compressor.

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 and relieves air pressure in the pump and transfer tube when the air pressure in the tank reaches the kick-out pressure. As compressed air is used and the pressure level in the tank drops to the kick-in pressure, the pressure switch restarts the motor automatically, without warning and the pump resumes compressing air.

The air line outlet (see E). Connect 1 / 4 NPT air hose to this outlet.

ASSEMBLING THE COMPRESSOR

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 and parts manuals

1. 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.
2. Locate the compressor according to the following guidelines:

WARNING

Never locate the compressor in an area where there

are fumes from flammable fluids such as paint, solvents, or gasoline. It is normal for the motor and pressure switch to produce sparks while operating. If sparks come into contact with flammable fumes, they may ignite, causing a fire or explosion. Always operate the compressor in a well ventilated area.

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 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 compressors in a heated building when not in use. 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.

WARNING

Risk of injury: The shipping pallet is not designed as a base for packing compressor. Operating the compressor while it is on the pallet is your warranty.

e. To prevent damage to tank and pump, the tank must be shimmmed so the pump is level within 1/8 per lineal foot maximum to distribute oil properly. Fasten to floor and NEVER force tank feet to floor without shims when tightening. We also recommend the use of vibration pads (094-0137) under tank feet (C).
4. Connect an air hose (not included) to the compressor.

WARNING

Risk of bursting, resulting in

injury. Never use Plastic pipe for compressed air.

CAUTION

Risk of property damage. Never use lubricator

for paint spraying or similar applications.

AIR DRYERS AND AFTER COOLERS

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

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. 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

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.

COMPRESSOR CONTROLS

Refer to Fig. 3.

WARNING switch and must

For your safety, tank pressure is preset within the never be tampered with.

Pressure Switch (see A)

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.

Pressure Relief Valve (see B)

If the pressure switch does not shut down the motor when pressure reaches the preset level, this valve will pop open automatically to prevent over pressurization. To operate manually, pull the ring on the valve to relieve air pressure in the tank.

Tank Pressure Gauge (see C)

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

WARNING

Risk of electrical shock. Improper electrical grounding electrical shock. The wiring should be done by a qualified

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.

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.

NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use dual element time delay fuses (Buss Fusetron type "T" only).

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.

MOTOR RESET SWITCH AND WIRING

WARNING

Ensure that all guards and shrouds are in place before

pressing the reset switch to restart the motor.

TOPS senses both temperature and current, providing more complete motor overload protection than a magnetic starter, which senses only current. If TOPS senses an overload condition, it will automatically shut down the compressor.

Allow 10-15 minutes for the unit to cool down, than press the reset button on the motor to restart the compressor.

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 A) to restart the motor (see Fig. 5).

Note: On stationary models not supplied with a power cord, the electrical power must be wired into the pressure switch by a Licensed Electrician.

OPERATING INSTRUCTIONS

2. Make sure the main power disconnect switch is shut OFF.
3. Close the tank petcock (see E).
4. Turn ON the main power disconnect switch. Turn the pressure switch to the AUTO position (see D). The pump will start filling the tank with air. When the air pressure in the tank reaches the level preset at the factory, the pressure switch will turn off the electric motor. As air is used and the pressure level in the tank drops, the pressure switch will start the motor and the pump will begin refilling the tank.

WARNING

WARNING High temperatures are generated by the pump. To prevent burns or other injuries, DO NOT touch the pump or transfer tube while the pump is running. Allow it to cool before handling or servicing. Keep children away from the compressor at all times.

NOTE: If the unit does not operate properly, SHUT DOWN IMMEDIATELY, and contact your nearest Service Center or call the factory's Customer Service Department. DO NOT return the unit to the store where it was purchased.

COLD WEATHER STARTING

In cold weather check that the air filter is clean. ALWAYS use synthetic blend, non-detergent air compressor oil.

Open the petcock (F) (Fig. 6) to depressurize the tank to zero PSI before starting. If the compressor will not start, relocate it in a warmer location.

SHUTDOWN (Fig. 6)

1. Turn the pressure switch to the OFF position (see C).
2. Shut OFF the main power disconnect switch.
3. Reduce pressure in the tank through the outlet hose. You can also pull the tank safety valve ring (see G) and keep it open to relieve pressure in the tank.

WARNING

WANrine Escaping air and moisture can propel debris that may cause eye injury. Wear safety goggles when opening petcock.

1. Open the petcock (see F) to allow moisture to drain from the tank.

MAINTENANCE

MAINTENANCE

WARNING To avoid personal injury, always shut off and unplug the compressor and relieve all air pressure from the system before performing any service on the air compressor.

Regular maintenance will ensure trouble-free operation. Your electric powered air compressor represents high-quality engineering and construction; however, even high-quality machinery requires periodic maintenance. The items listed below should be inspected on a regular basis

DRAINING THE TANK (Fig. 6)

WARNING Condensation will accumulate in the tank. To prevent corrosion of the tank from the inside, this moisture must be drained at the end of every workday.

WARNING Be sure to wear protective eyewear. Relieve the air pressure in the system and open the petcock on the bottom of the tank to drain.

CHECKING THE OIL

Check the level of oil in the pump with the sight glass. The pump oil level must be between A and B (See Fig. 7). Do not overfill or underfill.

NOTE: Use synthetic blend non-detergent air compressor oil.

CHANGING THE OIL

Remove the oil plug (C) (Fig. 7) and drain the oil until it slows to a drip, then close. Add oil to the pump by first removing the breather plug (E). Add oil until the level viewed through the sight glass (D) is between FULL (A) and ADD (B). Never overfill or underfill the pump.

NOTE: The compressor is pre-filled with synthetic oil. Use synthetic blend, non-detergent air compressor oil.

BELT TENSION AND PULLEY ALIGNMENT

WARNING

To avoid personal injury, always shut off and pressor and relieve all air pressure from the system using any service on the air compressor.

NOTE: Drive belt tensioning and pulley alignment are done at the same time. They are discussed separately for clarity.

ADJUSTING DRIVE BELT TENSION

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 (13 mm) occurs by placing 5 lb (2.3 kg) 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 belt guard.
2. Loosen the motor mounting bolts.
3. Shift the motor to the point where the correct deflection exists.
4. Retighten the motor mounting bolts.
5. Check to ensure that the tension remained correct.
6. Reinstall the belt guard. All moving parts must be guarded.

MAINTENANCE

PULLEY ALIGNMENT

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 belt guard.
2. Loosen the motor mounting bolts.
3. Loosen the setscrew on the motor pulley.
4. Align the motor pulley with the pump flywheel (C = D = E)
5. Retighten the motor pulley setscrew.
6. Adjust the proper belt tension.
7. Retighten the motor mounting bolts.
8. Reinstall the belt guard. All moving parts must be guarded.

MAINTENANCE

CLEANING THE AIR FILTER

A dirty air filter will reduce the compressor's performance and life. To avoid any internal contamination of the pump, the filter should be cleaned frequently, and replaced on a regular basis. Felt filters should be cleaned in warm, soapy water, rinsed, and allowed to air dry before reinstallation. Paper filters should be replaced when dirty. Do not allow the filter to become filled with dirt or paint. If the filter becomes filled with paint, it should be replaced. Direct exposure to dirty conditions or painting areas will void your wa

CHECKING THE RELIEF VALVE

Pull the relief valve daily to ensure that it is operating properly and to clear the valve of any possible obstructions.

TESTING FOR LEAKS

Check that all connections are tight. A small leak in any of the hoses, transfer tubes, or pipe connections will substantially reduce the performance of your air compressor. If you suspect a leak, spray a small amount of soapy water around the area of the suspected leak with a spray bottle. If bubbles appear, repair or replace the faulty component. Do not overtighten any connections.

STORAGE

Before storing the compressor for a prolonged period, use an air blow gun to clean all dust and debris from the compressor. Disconnect the power cord and coil it up. Pull the pressure relief valve to release all pressure from the tank. Drain all moisture from the tank. Clean the filter element and filter housing; replace the element if necessary. Drain the oil from the pump crankcase and replace it with new oil. Cover the entire unit to protect it from moisture and dust.
