Mains Plug Replacement 
(Middle East and Africa)
If a new mains plug needs to be fitted:
  •  Safely dispose of the old plug.
  •  Connect the brown lead to the live terminal in 
the plug.
  •  Connect the blue lead to the neutral terminal.
 
 WARNING: No connection is to be 
made to the earth terminal.
Follow the fitting instructions supplied with good 
quality plugs. Recommended fuse: 13 A.
Using an Extension Cable
If an extension cable is required, use an approved 
3–core extension cable suitable for the power input 
of this tool (see Technical Data).The minimum 
conductor size is 1.5 mm
2
; the maximum length 
is 30 m.
When using a cable reel, always unwind the cable 
completely.
ASSEMBLY AND ADJUSTMENTS
    WARNING: To reduce the risk of 
injury, turn unit off and disconnect 
machine from power source before 
installing and removing accessories, 
before adjusting or changing set-
ups or when making repairs. Be sure 
the trigger switch is in the OFF position. 
An accidental start-up can cause injury.
Fitting Sanding Discs (fi g. 2)
The tool uses 125 mm (5") hook and loop sanding 
discs with an 8 hole dust extraction pattern.
  1. Place the tool on a table, sanding pad (f) up.
  2. Place the sanding disc (i) directly on top of the 
sanding pad.
  3. Hold the sanding pad with one hand and align 
the dust extraction holes.
  4. Press the disc firmly onto the sanding pad.
Setting the Electronic Speed Control 
Dial (fi g. 1)
DWE6423
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 (fi g. 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 D
EWALT 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.
