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 |

NOTE: ALWAYS ensure the switch (B) is in the OFF (O) position and unit is
unplugged before removing or replacing pressure switch cover. PRESSURE
SWITCH
The pressure switch (not shown) automatically starts the motor when the air
tank pressure drops below the factory set cut-in pressure. It stops the motor
when the air tank pressure reaches the factory set cut-out pressure.
SAFETY VALVE
This valve (E) is designed to prevent system failures by relieving pressure
from the system when the compressed air reaches a predetermined level. The
valve is preset by the manufacturer and must not be removed or modified in any
way. CHECK VALVE
When the air compressor is operating, the check valve (I) is open, allowing
compressed air to enter the air tank. When the air compressor reaches cut-out
pressure, the check valve closes, allowing air pressure to remain inside the
air tank. AIR INTAKE FILTER
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:
- Set the Auto/Off switch to OFF (O) and unplug unit.
- Allow the motor to cool.
- Depress the red reset button (N) on the motor.
- Plug the power cord into the correct branch circuit receptacle.
- Set the Auto/Off switch to AUTO (-).
INSTALLATION
Assembly
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:

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.

A qualified electrician needs to know the following before wiring:
- The amperage rating of the electrical box is adequate. Refer to the Specifications, in the parts manual, for this information.
- 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.

This condensate contains lubricating oil and/or substances which may be
regulated and must be disposed of in accordance with local, state, and federal
laws and regulations.
-
Set the Auto/Off switch to “OFF (O)”.
-
Pull ring on safety valve allowing air to bleed from the tank untiltank pressure is approximately 20 PSI. Release safety valvering.
-
Drain water from air tank by opening drain valve (clockwise) onbottom of tank.
WARNING: Risk of bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank causing a risk of air tank rupture.
NOTICE: Risk of property damage. Drain water from air tank may contain oil and rust which can cause stains. -
After the water has been drained, close the drain valve (counterclockwise). The air compressor can now be stored.
NOTE: If drain valve is plugged, release all air pressure. The valve can
then be removed, cleaned, then reinstalled.
Compressor Pump Oil (Fig. 3)
NOTICE: Risk of property damage. Use air compressor oil only. Multi-
weight automotive engine oils like 10W30 should not be used in air
compressors. They leave carbon deposits on critical components, thus reducing
performance and compressor life.
NOTE: Use synthetic blend, non-detergent air compressor oil.
NOTE: Crankcase oil capacity is approximately 37 fluid ounces (1094.2
ml).
Checking
- The oil level should be to the middle of the sight glass (X).
- If needed, remove oil fill plug (Y) and slowly add oil until it reaches the middle of the sight glass.
Changing
WARNING: Drain tank to release air pressure before removing the oil fill
plug or oil drain plug.
-
Remove the oil fill plug (Y).
-
Remove the oil drain plug (W) and drain oil into a suitable container.
-
Replace the oil drain plug (W) and tighten securely
-
Slowly add compressor oil until it reaches the middle of the sight glass (X).
NOTE: When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full.
CAUTION: Overfilling with oil will cause premature compressorfailure. Do not overfill. -
Replace oil fill plug (Y) and tighten securely.
Belt Replacement
WARNING: This unit starts automatically. ALWAYS shut off and unplug the
compressor, 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. Hot surfaces. Risk of burn. Pump head, and surrounding
parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 1).
Allow compressor to cool prior to servicing.
- Set the Auto/Off lever to “OFF (O)”, unplug the unit, and relieveall air pressure from the air tank.
- Remove the outer belt guard (Z).
- Mark motor position on saddle.
- Loosen the motor mounting screws and slide the motor toward the air compressor pump.
- Remove the belt and replace with a new one.
- See the Adjusting Belt Tension before tightening motor mounting screws.
Adjusting Belt Tension
- Slide motor into original position, line the motor up with the mark made earlier on saddle.
- Tighten two outside motor mounting screws enough to hold the motor in place for checking pulley and flywheel alignment.
- 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.
- 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:
- Set the Auto/Off lever to “OFF (O)”, unplug the unit, and relieve all air pressure from the air tank.
- Remove outer belt guard.
- Place a straightedge against the outside of the flywheel.
- 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).
- 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.
- Tighten the motor drive pulley set screw. Torque to 145-160 in-lbs. (16.4-18.1 Nm).
- 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.
- Retighten the motor drive pulley set screw. Torque to 145-160 in.-lbs. (16.4- 18.1 Nm).
- 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
- Turn the Auto/Off switch to “Auto (1)” and allow tank pressure to build. Motor will stop when tank pressure reaches “cut-out” pressure.
- Set the Auto/Off switch to “Off (O)” and unplug unit.
- Apply a soap solution to all air-line fittings and connections/ piping to look for any leaks.
- Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring.
- Drain water from air tank by opening drain valve on bottom of tank.
- Correct any leaks found.
IMPORTANT: Even minor leaks can cause the air compressor to overwork,
resulting in premature breakdown or inadequate performance.
Air compressor Head Bolts – Torquing
The air compressor pump head bolts should be kept properly torqued. Check the
torques of the head bolts after the first five hours of operation. Torque to
20-24 ft.-lbs. (28-32 Nm).
