Since the air compressor and other components (material pump, spray guns, filters, lubricators, hoses, etc.) used make up a high pressure pumping system, the following safety precautions must be observed at all times:

DANGER

BREATHABLE AIR WARNING

This compressor/pump is not equipped and should not be used "as is" to supply breathing quality air. For any application of air for human consumption, the air compressor/pump will need to be fitted with suitable in-line safety and alarm equipment. This additional equipment is necessary to properly filter and purify the air to meet minimal specifications for Grade D breathing as described in Compressed Gas Association Commodity Specification G 7.1, OSHA 29 CFR 1910. 134, and/or Canadian Standards Associations (CSA).

DISCLAIMER OF WARRANTIES

In the event the compressor is used for the purpose of breathing air application and proper in-line safety and alarm equipment is not simultaneously used, existing warranties shall be voided, and the manufacturer disclaims any liability whatsoever for any loss, personal injury or damage.

General Safety

• Read all manuals included with this product carefully. Be thoroughly familiar with the controls and the proper use of the equipment.
• Follow all local electrical and safety codes as well as the United States National Electrical Codes (NEC) and Occupational Safety and Health Act (OSHA).
• Only persons well acquainted with these rules of safe operation should be allowed to use the compressor.
• Keep visitors away and NEVER allow children in the work area.
• Wear safety glasses and use hearing protection when operating the unit.
• Do not stand on or use the unit as a handhold.
• Before each use, inspect compressed air system and electrical components for signs of damage, deterioration, weakness or leakage. Repair or replace defective items before using.
• Check all fasteners at frequent intervals for proper tightness.

⚠ WARNING Motors, electrical equipment and controls can cause electrical arcs that will ignite a flammable gas or vapor. Never operate or repair in or near a flammable gas or vapor. Never store flammable liquids or gases in the vicinity of the compressor.

⚠ WARNING Never operate compressor without a beltguard. This unit can start automatically without warning. Personal injury or property damage could occur from contact with moving parts.

- Do not wear loose clothing or jewelry that will get caught in the moving parts of the unit.

CAUTION Compressor parts may be hot even if the unit is stopped.

• Keep fingers away from a running compressor; fast moving and hot parts will cause injury and/or burns.
• If the equipment should start to vibrate abnormally, STOP the engine/motor and check immediately for the cause. Vibration is generally an indication of trouble.

- To reduce fire hazard, keep engine/motor exterior free of oil, solvent, or excessive grease.

⚠ WARNING An ASME code safety relief valve with a setting no higher than the Maximum Allowable Working Pressure (MAWP) of the tank MUST be installed in the air lines or in the tank for this compressor. The ASME safety valve must have sufficient flow and pressure ratings to protect the pressurized components from bursting. The flow rating can be found in the parts manual. The safety valve in the intercooler does not provide system protection.

⚠ WARNING Maximum operating pressure is 135 psi for single stage compressors. Do not operate with pressure switch or pilot valves set higher than 135 psi (single stage).

- Never attempt to adjust ASME safety valve. Keep safety valve free from paint and other accumulations.

Important Safety Information (Continued)

⚠ WARNING

Never attempt to repair or modify a tank! Welding, drilling or any other modification will weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked

or damaged tanks.

NOTICE

Drain liquid from tank daily.

• Tanks rust from moisture build-up, which weakens the tank. Make sure to drain tank regularly and inspect periodically for unsafe conditions such as rust formation and corrosion.
• Fast moving air will stir up dust and debris which may be harmful. Release air slowly when draining moisture or depressurizing the compressor system.

Spraying Precautions

Do not spray flammable materials in vicinity of open flame or near ignition sources including the compressor unit.

• Do not smoke when spraying paint, insecticides, or other flammable substances.
• Use a face mask/respirator when spraying and spray in a well ventilated area to prevent health and fire hazards.
• Do not direct paint or other sprayed material at the compressor. Locate compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor.
• When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer.

INSTALLATION INSTRUCTIONS

Grounding

This product must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric shock by providing an escape wire for the electric current. This product is equipped with a cord having a grounding wire with an appropriate grounding plug. The plug must be plugged into an outlet that is properly installed and grounded in accordance with all local codes and ordinances. Do not use grounding adapter.

WARNING

Risk of electric shock. Improper use of grounding plug can result in a risk of electrical shock. Plug must be plugged into an outlet that is properly installed and grounded in accordance with local

codes and ordinances by a qualified electrician.

This product comes from the factory ready for use on a nominal 120 volt circuit and has a grounding plug similar to the plug illustrated in Figure 2. If the listed conditions cannot be met or if nuisance tripping of the current protection device occurs, it may be possible to operate the compressor from a 120 volt 20 amp circuit. See Figure 2.

Check motor data plate for 240 volt compatibility. A 240 volt unit must be operated on a 240 volt circuit. The cord must only plug into a 240 volt grounded outlet and may require a new cord and plug. See Figure 3. This product may be modified to operate at 240V. To do so, a 240V power cord needs to be purchased and installed on the unit and wired into the pressure switch just like the 120V cord. The panel on the back of the motor needs to be opened and the flag terminals need to be moved so that the brown wire that is on terminal #1 is on terminal #7 and the white wire that is on terminal #3 needs to be moved to terminal #1 (where the brown wire was originally). See Figure 4.

WARNING

All wiring and electrical connections should be performed by a qualified electrician. Installation must be in accordance with local codes and national electrical codes. If not properly grounded, the electrical shock, particularly when used in damp locations, in proximity of plumbing, outdoors.

this tool can cause an electrical shock, particularly when used in damp locations, in proximity of plumbing, outdoors.

WARNING

Installation of grounding plug can result in electric shock. When repair or replacement of the cord or plug is required, do not connect the grounding wire to either flat blade terminal. The

wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire. Never connect green (or green and yellow) wire to a live terminal.

INSTALLATION INSTRUCTIONS (CONTINUED)

Use only a 3-wire extension cord that has a 3-blade grounding plug and a 3-slot receptacle that accepts the plug on the product. Make sure your extension cord is not damaged. When using an extension cord, be sure to use one heavy enough to carry the current your product draws. For lengths less than 25 ft. 16-3 AWG extension cords shall be used. An undersized cord results in a drop in the voltage and loss of power and overheating. (NOTICE: Table below shows the correct size to use depending on cord length. When in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.)

Use of an extension cord may cause excess heat to motor. This could lead to tripped breaker (at electrical panel) or tripped thermal overload (on compressor motor). If this occurs, eliminate extension cord and plug compressor directly into electrical outlet. Avoid using extension cords; use longer air hose(s) instead.

Check with a qualified electrician or serviceman when the grounding instructions are not completely understood, or when in doubt as to whether the product is properly grounded. Do not modify the plug provided; if it does not fit the outlet, have the proper outlet installed by a qualified electrician. Only connect the product to an outlet having the same configuration as the plug. Do not use an adapter with this product.

INSTALLATION INSTRUCTIONS (CONTINUED)

Lubrication

Refererating compressor, ensure oil is filled to the center of the sight gauge (see figure 5).

Using a plotype of oil may shorten pump life and damage valves.

RECOMMENDED OIL (2 OPTIONS)

Single viscosity SAE30 ISO100 nondetergent compressor oil. Part number ST125303AV (0.5 qt) or ST126701AV (4 qt).

10W30 synthetic oil such as Mobile 1 or CE0032 (1 qt).

OIL CAPACITY

Approximately 8.5 oz.

Remove cap from oil fill opening. Install breather (found in parts bag with this manual). Check oil level. See specification label on compressor pump for the proper oil capacity and oil type. All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install appropriate water/oil removal equipment and controls as necessary for the intended application.

Do not use regular automotive oil. Additives in regular motor oil can cause valve deposits and reduce pump life. For maximum pump life, drain and replace oil after the first fifty (50) hours of operation. Then perform oil changes every three (3) months.

On/Off Cycling of Compressor

Pis of WARNING drain tank every day to prevent corrosion and possible injury due to tank damage. Do not operate drain with more than 40 psi in tank or drain valve may be damaged. Drain tank of moisture daily using the drain valve in the bottom of the tank.

NOTICE

Unit care and maintenance. Drain liquid from tank daily.

In the AUTO position, the compressor pumps air into the tank. When a shut-off (preset "cut-out") pressure is reached, the compressor automatically shuts off.

If the compressor is left in the AUTO position and air is depleted from the tank by use of a tire chuck, tool, etc., the compressor will restart automatically at its preset "cut-in" pressure. When a tool is being used continuously, the compressor will cycle on and off automatically.

In the OFF position, the compressor will not operate.

Drain Tank. Disconnect, tag, unplug and lock out power source; release pressure. Drain moisture from tank by opening drain valve underneath tank (See Figure 8).

Figure 8

MOISTURE IN COMPRESSED AIR

Moisture in compressed air will form into droplets as it comes from an air compressor pump. When humidity is high or when a compressor is in continuous use for an extended period of time, this moisture will collect in the tank. When using a paint spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun as droplets mixed with the spray material.

IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective. A filter in the air line, located as near to the gun as possible, will help eliminate this moisture.

TROUBLESHOOTING GUIDE

MAINTENANCE AND INSPECTION INSTRUCTIONS

WARNING

Disconnect, tag and lock out power source then release all pressure from the system before attempting to install, service, relocate or perform any maintenance.

In order to maintain efficient operation of the compressor system, check the air filter and oil level before each use. The ASME safety valve should also be checked daily (see Figure 9). Pull ring on safety valve and allow the ring to snap back to normal position. This valve automatically releases air if the tank pressure exceeds the preset maximum. If air leaks after the ring has been released, or the valve is stuck and cannot be actuated by the ring, the ASME safety valve must be replaced.

WARNING

Do not tamper with the ASME safety valve.

Figure 9 - ASME Safety Valve

Tank

WARNING

Never attempt to repair or modify a tank! Welding, drilling or any other modification will weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked

or damaged tanks.

Drain liquid from tank daily.

The tank should be carefully inspected at a minimum of once a year. Look for cracks forming near the welds. If a crack is detected, remove pressure from tank immediately and replace.

Compressor Lubrication

See Installation. Add oil as required. The oil should be changed every three months or after every 200 hours of operation; whichever comes first.

If the compressor is run under humid conditions for short periods of time, the humidity will condense in the crankcase and cause the oil to look creamy. Oil contaminated by condensed water will not provide adequate lubrication and must be changed immediately. Using contaminated oil will damage bearings, pistons, cylinders and rings and is not covered under warranty. To avoid water condensation in the oil, periodically run the compressor with tank pressure near 120 psi for single stage compressors by opening the drain cock or an air valve connected to the tank or hose. Run the pump for an hour at a time at least once a week or more often if the condensation reoccurs.

IMPORTANT: Change oil after first 50 hours of operation.

Air Filter

Never run the compressor pump without an intake air filter or with a clogged intake air filter. The air filter element should be checked monthly (see Figure 10). Operating compressor with a dirty filter can cause high oil consumption and increase oil contamination in the discharge air. If the air filter is dirty it must be replaced.

Components

Turn off all power and clean the cylinder head, motor, fan blades, air lines, aftercooler and tank on a monthly basis.

MAINTENANCE AND INSPECTION INSTRUCTIONS (CONTINUED)

Belts

Look to bring the power then release all pressure from the tank to prevent unexpected movement of the unit.

Check belt tension every 3 months. Adjust belt tension to allow 3/8 inch to 1/2 inch deflection with normal thumb pressure. Also, align belts using a straight edge against the face of the flywheel and touching the rim on both sides of the face. The belts should be parallel to this straight edge (see Figure 11). Dimension A should be the same as B and C to ensure proper alignment of the belts.

Slots in the bed-plate allow for sliding the motor back and forth to adjust belt tension.
