WARNING

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement, and other masonry products.

• Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially designed to filter out microscopic particles.

The Model H3372 represents a heavy load at 142 pounds. Seek assistance before moving.

This air compressor is shipped from the manufacturer in a carefully packed carton. If you discover the machine is damaged after you have signed for delivery, and the truck and driver are gone, you will need to file a freight claim with the carrier. Save the containers and all packing materials for possible inspection by the carrier or its agent. Without the packing materials, filing a freight claim can be difficult. If you need

assistance determining whether you need to file a freight claim, or with the procedure to file one, please contact our Customer Service at (570) 546-9663.

When determining where to set up the compressor in the shop, or when taking the air compressor to a job site, the most important consideration is access to an adequate and properly fused power supply. Refer to Circuit Requirements for the needs of your particular compressor.

Also, make sure the compressor is not operating in an environment where there are any explosive, flammable or caustic fumes or gases. A clear and well ventilated area is best for its safe operation.

Place the compressor on a solid and level surface. Make sure that the hoses you attach to your pneumatic device will be unrestricted in movement and not subject to being run over by vehicles or punctured by any sharp objects in the area.

Since air compressors are often used for a sustained period of time, sometimes in restricted areas, it is also best to wear ear protection to avoid long term exposure to the sound of the electric motor and compression pump.

Long term exposure to this machine may cause hearing loss. Wear approved hearing protection while operating this machine to minimize this risk!

Unpacking

Site Placement

Do not place the compressor next to any flammable liquids or gas! The compressor cylinder head and feed pipe can reach high temperatures and could cause the flammable gas to ignite. Keep work area clear from flammable gas when using the compressor.

CIRCUIT REQUIREMENTS

Wiring:

The Model H3372 3 HP Air Compressor is wired for 220V operation.

Amperage Draw

The Model H3372 has a 3 HP motor and draws the following amperage.

H3372 Motor.................................18 Amps

Circuit Breaker Requirements

Install your air compressor on a dedicated circuit to reduce the possibility of overloading the circuit and tripping the circuit breaker. However, if an unusual load does not exist, and the circuit breaker still trips, have the circuit inspected by a qualified electrician. Never use a larger circuit breaker than stated below, or you will increase the risk of fire.

Circuit Breaker...........20 Amp Double Pole

220V Operation

Extension Cords

In the event of an electrical short, grounding reduces the risk of electric shock by providing a path of least resistance to disperse electric current. These machines are equipped with power cords having an equipment-grounding conductor. See Figure 1. The outlet must be properly installed and grounded in accordance with all local codes and ordinances.

Grounding

Figure 1. Ground plug configuration.

If you find it necessary to use an extension cord with your compressor, make sure the cord is rated Standard Service (grade S) or better. The extension cord must also contain a ground wire and plug pin. Always repair or replace extension cords when they become worn or damaged.

Overheating, short circuit and fire damage will result form inadequate wiring. Follow the guidelines in this section.

Potential for electrical shock hazard, this equipment must be grounded. Verify that any existing electrical outlet and circuit you use is actually grounded.
