5.Check pump oil level, see Compressor Pump Oil under Maintenance.

CAUTION: Do not operate without oil or with inadequate oil. DEWALT is not responsible for compressor failure caused by inadequate oil.

6.Check engine's oil and fuel level, see engine's instruction manual for correct procedures.

7.Visually inspect drive belt. Replace belt if frayed, cracked, or worn. NOTE: Outer belt cover must be removed to inspect drive belt.

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

Initial Set-up

Read safety instructions before setting-up air compressor.

BREAK-IN PROCEDURE

WARNING: 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 used for the first time.

•When the unloader valve has been replaced.

•When the compressor pump has been replaced.

The procedure:

1. Follow Pre-Start Checklist under Preparation for Use.

2. Rotate the unloader's manual lock to the open position to prevent air tank pressure buildup.

3. Open the pressure regulator. Pull regulator knob (F) out and rotate clockwise until it stops.

WARNING: Do not operate this unit until you read and understand the engine instruction's manual for safety, operation and maintenance instructions.

4.Prepare engine for first time use, see engine's instruction manual for correct procedure.

5.Turn the engine ON/OFF switch (C) to the ON Position.

6.Start engine, see engine's instruction manual for correct procedure.

7.Run the air compressor for 30 minutes to seat the rings and lubricate all the internal surfaces. Ensure there is no pressure build up in the air tank by observing the reading on the air tank pressure gauge.

8.Rotate the manual lock on the unloader valve into the closed position so the air tank pressure can build.

9.Close the pressure regulator. Rotate the regulator knob (F) counterclockwise to its built-in stop and push knob in to lock in place. This will allow air to build pressure in the air tank.

10.Compressed air will be available from the hose air outlet until it is used up or bled off.

OPERATING PROCEDURES

Start-up (Fig. 1)

1.Follow Pre-Start Checklist under Preparation for Use.

2.Pull out and turn regulator knob (F) counterclockwise until fully closed. Push in to lock. Regulated pressure gauge should read 0 PSI (0 kPa).

3.Rotate the manual lock unloader lever to the open position to assist with start up.

4.Turn the engine ON/OFF switch (C) to the ON Position.

5.Start engine, see engine's instruction manual for correct procedure.

6.Rotate manual lock unloader lever to the closed position to allow air tank pressure to build. NOTE: Pump will not operate with the manual lock unloader lever in the open position.
