WARNING
Avoid electrical shock hazard. Never use this compressor with a damaged or frayed electrical cord or extension cord. Inspect all electrical cords regularly. Never use in near water or in any environment where electric shock is possible.

SAFETY VALVE
This compressor is equipped with a safety valve that is set to avoid over- pressurization of the air tanks. This valve is factory pre-set and will not function unless tank pressure reaches this pressure.

WARNING
DO NOT ATTEMPT TO ADJUST OR ELIMINATE THIS SAFETY DEVICE. ANY ADJUSTMENTS TO THIS VALVE COULD CAUSE SERIOUS INJURY. If this device requires service or maintenance, see an Authorized DEWALT Service Center.

Attachments and Accessories
For any attachment or accessory you will be using with this compressor, the maximum allowable recommended pressure should be clearly marked on the product or should be clearly noted within the operations manual. Exceeding the pressure rating of these attachments (including, but not limited toair tools, air operated accessories, spray guns, air hose, air hose connections, tires and other inflatables) could cause them to fly apart or explode and could result in serious injury.

Never exceed the maximum allowable pressure recommended by the manufacturer of any attachment or accessory you use with this compressor.

DUTY CYCLE
To ensure long life of your DEWALT air compressor, do
not operate on more than the duty cycle indicated on the technical data plate. If, for example, this air compressor pumps air more than 25% of one hour, then the compressor’s capability is less than the air delivery required by the application. Always match the air volume requirements of the attachment or accessory with the air volume delivery of the compressor.
To avoid overheating of the electric motor, this compressor is designed for intermittent operation as indicated on the technical dataplate (for example, S3-25 means 2.5 minutes ON, 7.5 minutes OFF).

DPC16PS ONLY
Caution : Risk of personal injury. Avoid placing hands between handle and top panel when assembling to prevent pinching.

1. Place handle (5) into bushings on top panel (7).

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 (15) 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.

CAUTION
The compressor was shipped with oil in the crankcase. Please check carefully if the oil is at the right level. Do not attempt to operate this air compressor without first checking the oil level in the crankcase. Serious damage can result from even limited operation unless filled with oil and broken in correctly. Closely follow Initial Set-up under Operation having completed all required steps.

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 (13) and check oil level. Gradually add DEWALT synthetic or SAE 40, non-detergent air compressor oil if required. NOTE: See Specifications for pump oil capacity.

Caution
Risk of unsafe operation. Overfilling with oil will cause premature compressor failure. Do not overfill.

Reposition dipstick.

NOTE: Some units (DPC6MRC, DPC10RC) are equipped with an oil-free pump. There is no oil to replace or check.

ELECTRICAL CONNECTION
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts.
Damaged or entangled cords increase the risk of electric shock.
Single-phase compressors are supplied with an electrical cable and a two-pole & earth plug. The compressor must be connected to a grounded power socket.

IMPORTANT
Never use the ground socket instead of the neutral wire. The ground connection must be made to meet safety standards (EN 60204). The plug of the power cable must not be used as a switch, but must be fitted in a power socket controlled by a suitable differential switch thermalbreaker).

DANGER
RISK OF ELECTRICAL SHOCK. IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.
Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be installed by a qualified electrician.
Repairs to the cord set or plug MUST be made by a qualified electrician.

PREPARATION FOR USE

PRE-START CHECKLIST

1. Ensure the On/Off switch (6) is in the OFF position.

2. Plug the power cord into the correct branch circuit receptacle. See Electrical Connection (above).

3. Ensure air tank is drained, see Draining Air Tank under Maintenance.

4. Ensure the drain valve (2) is closed.

5. Ensure safety valve (14) is functioning properly, see Checking Safety Valve under Maintenance.

6. Check pump oil level, see Compressor Pump Oil under Maintenance. (DPC16PS Only)

7.  Turn regulator knob (4) counterclockwise until fully closed. Ensure regulated pressure gauge reads 0 bar (0 psi).

8. Attach hose and accessories.
   Warning : Risk of unsafe operation. Firmly grasp hose.

9. Ensure all covers and labels are in place, legible (for labels) and securely mounted. Do not use compressor until all items have been verified.

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 regulator outlet pressure must never exceed the maximum pressure rating.

INITIAL SET-UP
Warning: Do not operate this unit until you read and understand this instruction manual for safety, operation and maintenance instructions.

BREAK-IN PROCEDURE

CAUTION : Risk of property damage. Serious damage may result if the following break-in instructions are not closely followed.
This procedure is required before the air compressor is put into service for the first time and when the check valve or a compressor pump/motor has been replaced.

1. Ensure the On/Off switch (6) is in the OFF position.
   NOTE : If hose is not connected to Quick Connect body, pull coupler back until it clicks to prevent air from escaping through the quick connect.

2. Plug the power cord into the correct branch circuit receptacle. See Voltage and Circuit Protection under Installation.

3. Open the drain valve (counter-clockwise) fully to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

4. Move the On/Off switch to the ON position. The compressor will start.

5. Run the compressor for 20 minutes.

6. After 20 minutes, close the drain valve by turning clockwise. The tank will fill to cut-out pressure and the motor will stop.

7. Compressed air will be available until it is used or bled off.

STARTING

Check that the mains power matches that indicated on the electrical data-plate – the permissible tolerance range is +/-5%. Turn or press into position “0”. Fit the plug in the power socket and start the compressor, turning the pressure switch knob into position “I”.
The compressor is fully automatic, and is controlled by the pressure switch which stops it when tank pressure reaches maximum value and restarts it when it falls to minimum value. The pressure difference between maximum and minimum values is usually about 2 bar (29 psi). E.g.: the compressor stops when it reaches 8 bar (116 psi) – maximum operating pressure) and restarts automatically when the pressure inside the tank drops to 6 bar (87 psi). After connecting the compressor to the power line, load it to maximum pressure and check exactly how the machine is operating.
NOTE : The head/cylinder/delivery tube unit can reach high temperatures. Take care when working near these parts, and do not touch them to avoid possible burns.

IMPORTANT
The electro-compressors must be connected to a power socket protected by a suitable differential switch (thermal-breaker). The motor is equipped with an automatic thermal breaker located inside the winding – this stops the compressor when motor temperature reaches excessively high values (180oC). If the breaker is tripped, the compressors restart automatically after 10 to 15 minutes.
ADJUSTING OPERATING PRESSURE
You do not have to use the maximum operating pressure at all times. On the contrary, the pneumatic tool being used often requires less pressure. On compressors supplied with a pressure reducer, operating pressure must be correctly adjusted.

Adjust pressure to the required value by turning the knob (4) clockwise to increase pressure and anti-clockwise to reduce it. When you have obtained optimum pressure, lock the knob by pressing it downward. For pressure reducers equipped without a pressure gauge, the set pressure can be seen on the graduated scale located on the reducer body.
On pressure reducers equipped with a pressure gauge, pressure can be seen on the gauge itself.

WARNING : Some pressure regulators do not have “push to lock”, therefore simply turn the knob to adjust the pressure.

STOPPING THE COMPRESSOR

1. Turn or press the switch/button into position “0” (according to the type of pressure switch fitted on the compressor). DO NOT turn off the unit by switching off at the socket or pulling out the plug.
2. Turn regulator knob (4) counterclockwise until fully closed. Ensure regulated pressure gauge reads 0 bar (0 psi).
3. Remove hose and accessory.
4. Drain the air tank, see Draining Air Tank under Maintenance. Ensure air tank pressure gauge reads 0 bar (0 psi).
