SAVE THESE INSTRUCTIONS

Place this switch (A) in the ON position to

provide automatic power to the pres- sure switch and OFF to remove power at the end of each use. PRESSURE SWITCH The pressure switch (J) 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 If the pressure switch does not shut off the air

compressor at its cut-out pressure setting, the safety valve (G) will protect against high pressure by popping out at its factory set pressure (slightly higher than the pressure switch cut-out setting).11 English CHECK VALVE When the air compressor is operating, the check

valve (F) 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.

The tank pressure gauge (B) indi-cates the reserve air pressure in the tank.

OUTLET PRESSURE GAUGE

The outlet pressure gauge (C) indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure. REGULATOR The regulator (D) controls the air pressure shown on the outlet pressure gauge. Turn regulator knob clockwise to increase pressure and counterclockwise to decrease pressure.

UNIVERSAL QUICK CONNECT BODIES

The universal quick connect body (E) accepts the three most popular styles of quick connect plugs: Industrial, automotive, and ARO. One hand push-to-connect operation makes connections simple and easy. The two quick connect bodies allow the use of two tools at the same time. DRAIN VALVE The drain valve (H) 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. COOLING SYSTEM This compressor contains an advanced design cooling system. It is normal for this fan to blow air through the vent holes in large amounts. The cooling system is working when air is expelled.

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

This motor has a manual 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. Ensure the On/Off switch (A) is in the

2. Allow the motor to cool.

3. Depress the reset button (M) on the

motor. OIL DIPSTICK The oil dipstick (K) indicates the amount of oil in the pump. Check pump oil daily, see Compressor Pump Oil under Maintenance.

The filter (N) is designed to clean air entering the pump. To ensure the pump continually receives a clean, cool, and dry air supply the filter must always be clean and the filter intake must be free from obstructions. INSTALLATION Assembly (Fig. 1) INSTALLING HANDLE CAUTION: Risk of personal injury. Avoid placing hands between handle and top panel when assembling to prevent pinching.

1. Place handle (O) into bushings on top panel (Q).

2. Depress snap buttons and slide handle through first bushings

until it stops at second bushings.

3. Reach under top panel and depress snap buttons again and

slide through second bushings.

4. Pull handle all the way up until it stops. Turn knobs (P) to lock

handle in place. IMPORTANT: Always pull handle up and lock in place before using as a dolly.

5. If not using the dolly feature, loosen knobs and push handle

down until it stops. INSTALLING HOSES

WARNING: Risk of unsafe operation. Firmly grasp hose in hand

when installing or disconnecting to prevent hose whip.

1. Ensure regulated pressure gauge reads 0 PSI (0 kPa).

2. Grasp the hose at the quick connect plug and push the

plug into the quick connect body (E). Coupler will snap into place.

3. Grasp the hose and pull to ensure coupler is seated.

WARNING: Risk of unsafe operation. Firmly grasp hose in hand

when installing or disconnecting to prevent hose whip.

1. Ensure regulated pressure gauge reads 0 PSI (0 kPa).

2. Pull coupler on quick connect body back to release quick

connect plug on hose. Lubrication and Oil CAUTION: The compressor was shipped without oil in the crankcase. A small amount of oil may be present in the pump upon receipt of the air compressor. This is due to testing and does not mean the pump contains oil. Do not attempt to operate this air compressor without rst adding oil to the crankcase. Serious damage can result from even limited operation unless lled with oil and broken in correctly. Closely follow Initial Set-up under Operation. CAUTION: Multi-viscosity motor oils, like 10W30, should not be used in an air compressor. They leave carbon deposits on critical components, thus reducing performance and compressor life. Use DeWalt synthetic or SAE 40, non-detergent air compressor oil.

1. Place unit on a level surface.

2. Remove dipstick (K) and slowly add DeWalt

synthetic or SAE 40, non-detergent air compressor oil (supplied). NOTE: See Specifications for pump oil capacity. CAUTION: Risk of unsafe operation. Overlling with oil will cause premature compressor failure. Do not overll.

3. Replace dipstick.13

English 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. The portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug.

1. The cord set and plug (R) with this

unit contains a grounding pin (S). This plug MUST be used with a grounded outlet (T). IMPORTANT: The outlet being used must be installed and grounded in accordance with all local codes and ordinances.

2. Ensure the outlet being used has the same configuration as

the grounded plug. DO NOT USE AN ADAPTER.

3. Inspect the plug and cord before each use. Do not use if there

are signs of damage.

4. If these grounding instructions are not completely understood,

or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

DANGER: Risk of electrical shock. IMPROPER GROUNDING

CAN RESULT IN ELECTRICAL SHOCK. Do not modify the plug provided. If it does not t the available outlet, a correct outlet should be installed by a qualied electri- cian. Repairs to the cord set or plug MUST be made by a qualied electrician. Extension Cords Using extension cords is not recommended. The use of extension cords will cause voltage to drop resulting in power loss to the motor and overheating. Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed. If an extension cord must be used, be sure it is:

• a3wireextensioncordthathasa3bladegroundingplug,and a 3-slot receptacle that will accept the plug on the product

• 12gauge(AWG)orlarger.(Wiresizeincreasesasgaugenum- ber decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.) Voltage and Circuit Protection Refer to the Voltage and Minimum Branch Circuit Requirements under Specications. CAUTION: Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.

• Circuit is equipped with a15 amp circuit breaker or 15 amp time delay fuse. NOTE: If compressor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked “D” in Canada and “T” in the US.

T14 English If any of the above conditions cannot be met, or if operation of the compressor repeatedly causes interruption of the power, it may be necessary to operate it from a 20 amp circuit. It is not necessary to change the cord set. 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 Place the air compressor in a clean, dry and well ventilated area at least 12" (30.5 cm) away from the wall or other obstructions that will interfere with the flow of air. Keep the compressor away from areas that have dirt and/or volatile fumes in the atmosphere. These impurities may clog the intake filter and valves, causing inefficient operation. The air compressor pump and shroud are designed to allow for proper cooling. The ventilation openings on the compressor are necessary to maintain proper operating temperature. Do not place rags or other containers on or near these openings. Place the air compressor on a flat surface resting on the rubber feet. 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 D

The low pressure at which the motor automatically restarts is called cut-in pressure. Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off, protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called cut-out pressure. Branch Circuit: The circuit carrying electricity from electrical panel to outlet. Duty Cycle: For proper operation of your air compressor, it is recommended that a 50% duty cycle be maintained; that is, the air compressor should not run more than 5 minutes in any 10 minute period.21 English Troubleshooting Guide This section provides a list of the more frequently encountered malfunctions, their causes and corrective actions. The operator or maintenance personnel can perform some corrective actions, and others may require the assistance of a qualified DeWALT technician or your dealer.
