PRE-START CHECKLIST 

• Drain water from air compressor tank and condensation from 

  air lines. (Please refer to air compressor’s operation manual.)

• Lubricate the tool.(Please refer to the “Maintenance” section 

  in the manual.)

WARNING: Risk of unsafe operation. Firmly grasp air hose with 

hand when installing or disconnenting to prevent hose whip.

WARNING: Risk of bursting. Too much air pressure causes a  

hazardous risk of bursting. Check the manufacture’s maximum  

pressure rating for air tools and accessories. The regulator output 

pressure must never exceed the maximun pressure rating.

NOTE: The use of a quick connect set makes connecting easier

IMPORTANT:The use of air filters and air line lubricators 

is recommended.

SANDER PAD ASSEMBLY

• Disconnect the tool from the air supply before assembling or  

  disassembling the 

sander pad.

• To disassemble the 

sanding pad (B), slide the supplied wrench 

  between the 

sander pad (B) and skirt (G) until the wrench is in 

  contact with the flats of the 

balance shaft nut (H)

• Hold the 

wrench firmly and rotate the sander pad (B) 

  counterclockwise to loosen it from the tool. 

Using A Palm Sander Continued

9)   When using the tool, always adopt a firm footing and/or position 

and grip the tool firmly to counteract any forces or reaction 

forces that may be generated while using the tool.

10) Use only genuine Dewalt spare parts or parts which perform 

      equivalently. Do not make temporary or permanent repairs with 

      unauthorized parts. 

11) Do not lock, tape, wire, etc., the on/off trigger in the run 

position. The trigger must always be free to return to 

the “off” position when it is released.

12) Always shut off the air supply to the tool and depress the 

trigger to release air from the feed hose before fitting, 

adjusting or removing the working attachment.

13) Check hoses and fittings regularly for wear. Replace if 

necessary. Do not carry the tool by its hose. Ensure the 

hand is removed from the on/off trigger when carrying 

the tool with the air supply connected.

14) Take care against entanglement of moving tool parts 

with clothing, ties, hair, cleaning rags, etc. This will 

cause the body to be drawn towards the tool and can 

be very dangerous.

15) Safe working practices and observe all relevant legal 

requirements when installing, using or maintaining the tool.

16) Only install the tool when an easily accessible and easily 

operable on/off switch is incorporated in the air supply.

17) Take care that the tool exhaust air does not 

cause problems or blow onto another person.

18) Never lay a tool down unless the working attachment has 

stopped moving.

19) Always begin sanding with sandpaper coarse enough to 

remove high spots on the surface to be sanded.  

Progress to finer grit sandpaper until the desired finish is 

obtained.

20) Always use sandpaper appropriate for the surface 

being sanded.
