OPERATION
Instructions for Use
   WARNING: Always observe the safety 
instructions and applicable regulations.
   WARNING: To reduce the risk 
of serious personal injury, turn 
tool off and disconnect tool from 
power source before making any 
adjustments or removing/installing 
attachments or accessories.
 
 WARNING: 
 •  Make sure all materials to be sanded 
are well secured.
 •  Apply only a gentle pressure to the 
workpiece. Excessive pressure does 
not improve the sanding effect, but 
only results in an increased load on 
the machine and causes the abrasive 
to tear.
 • Avoid overloading.
    WARNING: Do not sand magnesium!
  NOTICE: If you wrap the cord around 
the tool when you store it, leave a 
generous loop of cord such that the 
strain relief (g, Fig. 1) does not bend. 
This helps prevent premature cord 
failure.
Proper Hand Position (Fig. 5)
   WARNING: To reduce the risk of 
serious personal injury, ALWAYS use 
proper hand position as shown. 
   WARNING: To reduce the risk of 
serious personal injury, ALWAYS hold 
securely in anticipation of a sudden 
reaction. 
Proper hand position requires either one hand on 
the sander body (j) or one hand on the main grip (p) 
as shown. 
Switching On and Off (Fig. 1)
Set the sanding speed using the electronic speed 
control dial (b).
To switch the tool on, set the on/off switch to 
position I.
To switch the tool off, set the on/off switch to 
position O.
Setting the Electronic Speed Control 
Dial (Fig. 1)
The speed is infinitely variable from 8,000–12,000 
min
-1
 using the electronic speed control dial (b).
Turn the electronic speed control dial to the required 
level. The correct setting, however, is a matter of 
experience.
Generally, harder materials require a higher setting.
Dust Extraction (Fig. 3, 4)
   WARNING: Since woodworking with a 
sander produces dust, always install a 
dust bag designed in compliance with 
the applicable directives regarding dust 
emission.
   WARNING: Do not use a dust bag or 
vacuum extractor without proper spark 
protection when sanding metal.
Your sander has two dust extraction methods: a 
built-in outlet (c) which allows either the supplied 
dust bag (d) or a shop vacuum system to be 
connected; and a dust skirt (n, Fig. 4). The built-in 
outlet utilizes the DEWALT airlock connection making 
it compatible with the DEWALT dust extractor and 
airlock accessory DWV9000.
TO ATTACH THE DUST BAG
  1. While holding the sander, fit the dust bag collar 
(e) to the outlet (c) as shown in Figure 3.
  2. Turn the collar (e) clockwise to lock the dust 
bag (d) in place.
TO EMPTY THE DUST BAG
NOTE: Be sure to wear approved eye protection 
and approved dust mask when performing this 
procedure.
For efficient dust extraction, empty the dust collector 
when it is about one third full.
  1. While holding the sander, turn the collar (e) 
anticlockwise to unlock the dust bag (d).
  2. Remove dust bag from the sander and gently 
shake or tap the dust bag to empty.
  3. Reattach the dust bag back onto the outlet and 
lock into place by turning the dust bag collar 
clockwise.
You may notice that all the dust will not come 
free from the bag. This will not affect sanding 
performance but will reduce the sander’s dust 
collection efficiency. To restore your sander’s dust 
collection efficiency, depress the spring inside the 
dust bag when you are emptying it and tap it on the 
side of the waste bin or dust receptacle.
