5

Leaking seals

Contact a DEWALT factory service center or a DEWALT

 

 

authorized service center.

 

 

 

6

Defective safety valve

Operate safety valve manually by pulling on ring. If valve still

 

 

leaks, it must be replaced.

 

 

 

7

Prolonged excessive use of air

Decrease amount of air usage.

 

 

 

8

Compressor is not large enough for accessory

Check the accessory air requirement. If it is higher than the

 

 

SCFM or pressure supplied by your air compressor, a larger

 

 

compressor is needed to operate accessory.

 

 

 

9

Hole in air hose

Check and replace air hose, if required.
