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:

• Failure to properly drain condensed water from air tank causes rust and thinning of thesteel 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 part substitutions to alter the factory set operating pressures.
Attachments & Accessories:
• Exceeding the pressure rating of air tools, spray guns, air operated accessories, tires and other inflatables can cause them to explode or fly apart, and could result in serious injury.| • Follow the equipment manufacturers recommendation and never exceed the maximum allowable pressure rating of attachments. Never use compressor to inflate small low pressure objects such as children’s toys, footballs, basketballs, etc.
Tires:
• Over inflation of tires could result in serious injury and property damage.| • Use a tire pressure gauge to check the tires pressure before each use and while inflating tires; see the tire sidewall for the correct tire pressure.

NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires very rapidly. Adjust pressure regulator on air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent over inflation.

DANGER: RISK OF INJURY OR PROP ER TY DAMAGE WHEN TRANSPORTING OR STORING

• Oil can leak or spill and could result in fire or breathing hazard; serious injury or death can result. Oil leaks will damage carpet, paint or other surfaces in vehicles or trailers.| • Always place 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. Always keep compressor level and never lie on its side.

The filter (A) is designed to clean air entering the pump. To ensure the pump continually receives a clean, cool, and dry air supply, the filter must alwaysbe clean and the filter intake must be free from obstructions. AIR TANK DRAIN VALVE
The drain valve (F) is located at the base of the air tank and is used to drain condensation at the end of each use. See Draining Air Tank under Maintenance. TANK PRESSURE GAUGE
The tank pressure gauge (C) indicates the reserve air pressure in the tank.
REGULATOR
(sold separately, not shown)
An air pressure regulator or a separate air transformer which combines the functions of air regulation and/or moisture and dirt removal is recommended for most applications. See Air Distribution System paragraph under Installation. WARNING: Risk of Bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools and accessories. The outlet pressuremust never exceed the maximum pressure rating of the tools or accessories.
AIR COMPRESSOR PUMP
The 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.
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart:

1. Set the Auto/Off switch to OFF (O) and unplug unit.
2. Allow the motor to cool.
3. Depress the red reset button (N) on the motor.
4. Plug the power cord into the correct branch circuit receptacle.
5. Set the Auto/Off switch to AUTO (-).

INSTALLATION

Assembly

Lubrication and Oil
AIR COMPRESSOR
The air compressor pump was filled WITH oil at the manufacturer. Check air compressor pump oil level before operating unit. See Compressor Pump Oil under Maintenance.
Compatibility
Air tools and accessories that are run off the compressor must be compatible with petroleum based products. If you suspect that a material is not compatible with petroleum products, an air line filter for removal of moisture and oil vapor in compressed air is required.
NOTE: Always use an air line filter to remove moisture and oil vapor when spraying paint.
Location

• Locate the air compressor in a clean, dry, and well ventilated area.

• Locate the air compressor at least 12″ (30.5 cm) away from the wall or other obstructions that will interfere with the flow of air.

• Locate the air compressor as close to the main power supply as possible to avoid using long lengths of electrical wiring.
  NOTE: Long lengths of electrical wiring could cause power loss to the motor.

• The air filter must be kept clear of obstructions which could reduce air flow to the air compressor.

HUMID AREAS
In frequently humid areas, moisture may form in the pump and produce sludge in the oil, causing running parts to wear out prematurely. Excessive moisture is especially likely to occur if the unit is located in an unheated area that is subject to large temperature changes. Two signs of excessive humidity are external condensation on the pump when it cools down and a “milky” appearance in compressor oil. You may be able to prevent moisture from forming in the pump by increasing ventilation or operating for longer intervals.
NOISE CONSIDERATIONS
Consult local officials for information regarding acceptable noise levels in your area. To reduce excessive noise, use vibration mounts or silencers, relocate the unit or construct total enclosures or baffle walls. Contact a DEWALT service center or call 1-888-895-4549 for assistance.
ANCHORING OF THE AIR COMPRESSOR
WARNING: Risk of bursting. Excessive vibration can weaken the air tank and cause an explosion. The compressor must be properly mounted.

If help is needed anchoring the air compressor consult a licensed contractor.

1. Place the air compressor on a level, solid concrete surface. Make sure the concrete is in good condition with no cracks or damage.
2. Mark the surface using the holes in the air compressor feet as a template.
3. Drill holes in the surface for the concrete anchors. Install concrete anchors.
4. Line-up holes in surface with holes in air compressor feet.
5. Place the vibration pads (not supplied) between the floor and air compressor feet, see figure. If needed use shims to level the unit.
6. Place the 3/8″ lag screws through the air compressor feet, vibration pads and into the anchors.
7. Torque 3/8″ lag screws to 7-10 ft.-lbs (9.5-13.5 Nm).

Electrical Wiring
WARNING: Improper electrical installation of this product may void its warranty and your fire insurance. Have circuit wiring performed by qualified personnel such as a licensed electrician who is familiar with the current national electrical code and any prevailinglocal electrical codes.
WARNING: Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician.
A qualified electrician needs to know the following before wiring:

1. The amperage rating of the electrical box is adequate. Refer to the Specifications, in the parts manual, for this information.
2. If the supply line has the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of motor, for this information.

NOTE: The wiring used must be rated for the motor nameplate voltage, plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire size, and maximum wire run. Undersized wire causes high amp draw and overheating to the motor.
NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use only time delay fuses.
WARNING: Risk of electrical shock. Electrical wiring mustbe located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.

Grounding Instructions

WARNING: Risk of electrical shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.
This product must be connected to a grounded, metallic, permanent wiring system, or an equipment-grounding terminal or lead on the product.
DANGER: Risk of electrical shock. IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.
Voltage and Circuit Protection
Refer to the Voltage and Minimum Branch Circuit Requirements under Specifications.

• Voltage supply to circuit must comply with the National Electrical Code.
• Circuit is not used to supply any other electrical needs.

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.
Air Distribution System
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.

INSTALLING AND DISCONNECTING HOSES

WARNING: Risk of unsafe operation. Firmly grasp hose in hand when installing or disconnecting to prevent hose whip. Ensure regulated pressure gauge reads 0 PSI.
The next figure represents a typical air distribution system. The following are tips to remember when setting up the air compressor’s air distribution system.
NOTE: Compressed air from 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 spray equipment, air tools and accessories requiring filtered air. Always read the instructions for the air tools and accessories being used.

• Use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air.
• If piping is over 100′ (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 underground lines are covered to make sure all pipe joints are free of leaks.
• A flexible coupling is recommended to be installed between the globe valve/air discharge outlet and 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 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.

3. The belt should deflect 3/16″ (4.8 mm) at midway between the pulley and the flywheel when a 5 pound (2.26 kg.) weight is applied at the midway point.
4. When proper belt tension is achieved, tighten motor mounting screws. Torque to 20-25 ft-lbs (27.1-33.9 Nm)

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″ (1.6 mm) to prevent excessive belt wear. Verify the alignment by performing the following Motor Pulley/Flywheel -Alignment.
Motor Pulley/Flywheel Alignment
To correct misalignment, perform the following steps:

1. Set the Auto/Off lever to “OFF (O)”, unplug the unit, and relieve all air pressure from the air tank.
2. Remove outer belt guard.
3. Place a straightedge against the outside of the flywheel.
4. Measure the distance between the edge of the belt and the straightedge at points A1 and A2. The difference between measurements should be no more than 1/16″ (1.6 mm).
5. If the difference is greater than 1/16″ (1.6 mm) loosen the set screw holding the motor drive pulley to the shaft and adjust the pulley’s position on the shaft until the A1 and A2 measure- ments are within 1/16″ (1.6 mm) of each other.
6. Tighten the motor drive pulley set screw. Torque to 145-160 in-lbs. (16.4-18.1 Nm).
7. Visually inspect the motor drive pulley to verify that it is perpendicular to the drive motor shaft. Points B1 and B2 should appear to be equal. If they are not, loosen the set screw of the motor drive pulley and equalize B1 and B2, using care not to disturb the belt alignment.
8. Retighten the motor drive pulley set screw. Torque to 145-160 in.-lbs. (16.4- 18.1 Nm).
9. Reinstall outer belt guard.

Air Compressor Pump Intake and Exhaust Valves
Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.
Inspect Air Lines and Fittings for Leaks

1. Turn the Auto/Off switch to “Auto (1)” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure.
2. Set the Auto/Off switch to “Off (O)” and unplug unit.
3. Apply a soap solution to all air-line fittings and connections/ piping to look for any leaks.
4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring.
5. Drain water from air tank by opening drain valve on bottom of tank.
6. Correct any leaks found.

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