2.Move compressor into an inclined position so drain valve (J) is at the lowest point (this will assist in removing moisture, dirt, etc. from air tanks)

3.Place a suitable container under the drain valve to catch discharge.

4.Grasp black lever on drain valve.

5.Slowly rotate lever to gradually bleed air from air tank.

CAUTION: Risk of Property Damage. Drain water from air tank may contain oil and rust which can cause stains.

6.When air tank pressure gauge reads 10 PSI (68.9 kPa), rotate valve to the fully open position.

7.Close drain valve when finished.

CHECKING OIL

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and surrounding parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 2). Allow compressor to cool prior to servicing.

1.Ensure engine ON/OFF switch (C) is in the OFF Position.

2.Place unit on a flat level surface.

3.Remove dipstick (L) and wipe clean.

4.Insert and remove dipstick without

threading dipstick into crankcase as shown in figure.

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: Risk of Unsafe Operation. Overfilling with oil will cause premature compressor failure. Do not overfill.

6. Replace dipstick and tighten securely.

CHANGING OIL

NOTE: Pump oil contains substances that are regulated and must be disposed of in accordance with local, state and federal laws and regulations.

WARNING: Hot surfaces. Risk of burn. Aftercooler, pump head, and surrounding parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 2). Allow compressor to cool prior to servicing.

1.Ensure engine ON/OFF switch (C) is in the OFF Position.

2.Allow the unit to cool.

3.Disconnect spark plug wire.

4.Drain air tank.

5.Locate a suitable container under pump drain plug (J).

6.Remove the dipstick (L) from crankcase.

7.Remove the oil drain plug (M).

8.Allow ample time for all oil to drain out. (Tilting the compressor towards the drain plug will assist in draining.)

9.Install the oil drain plug.

10.Fill pump with DEWALT synthetic compressor oil. Oil should not exceed top raised line on side of crackcase. (Oil will be even with bottom of threads in crankcase fill port.)

11.Install dipstick.

12.Reconnect spark plug wire.
