Speed Control Dial (DW443 & DW444 Only)
The speed control dial (5 incremental settings) allows you to increase
or decrease speed from 4000 - 6800 orbits per minute. The optimal
speed setting for each application is very much dependent on per-
sonal preference. You may want to experiment on a piece of scrap to
determine what gives you the best combination of finish quality and
material removal rate for your application. Generally, you will want to
use a higher setting on harder materials and a lower setting on softer
materials. Material removal rate increases as speed increases.
Dust Collection
Your sander comes equipped with a cloth filter bag to collect the
dust generated during sanding. To empty the dust bag, first turn off
and unplug tool. Firmly pull the bag off while holding the rubber boot
(Fig. 3). Empty the bag (you may want to turn it inside out.)
NOTE: Never operate this tool unless the dust collection bag is in
place.
