See engine instruction manual.

*To check for air leaks apply a solution of soapy water around joints. While compressor is pumping to pressure and after pressure cuts out, look for air bubbles to form.

**The pump oil must be changed after the first 20 hours or operation. Thereafter, when using DEWALT synthetic compressor oil, change oil every 200 hours of operation or once a year, whichever comes first.

+ Perform more frequent in dusty or humid conditions.

Checking Safety Valve (Fig. 1)

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.

WARNING: Risk of bursting. If the safety valve does not work properly, over-pressurization may occur, causing air tank rupture or an explosion.

Checking Air Filter Element (Fig. 1)

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 unit to cool.

3.Unscrew filter (A) top from filter base by turning counterclock- wise about 5 degrees.

4.Separate filter top from base.

5.Remove element from filter base.

6.If element needs cleaning, blow out with air. Replace if needed. Purchase replacement parts from your local dealer or authorized service center. Always use identical replacement parts.

7.Place element back in filter base.

8.Reconnect filter top to filter base. While pushing in, rotate clock- wise 5 degrees.

CAUTION: Risk of unsafe operation. Do not operate without air inlet filter.

Draining Air Tank (Fig. 1)

WARNING: Risk of unsafe operation. Risk from noise. Air tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use safety glasses when draining as debris can be kicked up into face. Use ear protection (ANSI S12.6 (S3.19) hearing protection) as air flow noise is loud when draining.

English

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

2.Ensure air tank pressure gauge reads 0 PSI (0 kPa). Drain air tank if necessary.

3.Grasp wire ring on safety valve (I).

4.Pull and release ring a few times to ensure plunger moves in and out.

15

NOTE: All compressed air systems generate condensate that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). 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.

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