EZ TWIST INTEGRATED WRENCH
This nose cap has an integrated wrench allowing you
to loosen and tighten the collet nut without the use of
the standard collet wrench.
1. Unscrew the nose cap from the tool, line-up the
steel insert on inside of the cap with the collet nut.
2. With the shaft lock engaged twist nose cap counter
clockwise to loosen the collet nut. Do not engage
the shaft lock while the tool is running.

DREMEL CHUCK 4486
The Dremel chuck allows you to quickly and easily
change accessories on Dremel tools without changing
collets. Accepts accessories with 0.8 - 3.2 mm shank.
To loosen, first press shaft lock button and rotate the
shaft by hand until it engages the shaft lock. Do not
engage the shaft lock while the tool is running.
With the shaft lock engaged use the wrench or the
EZ Twist nose cap to loosen the chuck and open the
jaws.
Remove the accessory from the chuck. If necessary,
continue loosening the chuck so that the new
accessory fits between the jaws. Insert the new
accessory into the chuck far enough so that there is
approximately 6 mm between the end of the chuck
and the beginning of the working part of the accessory.
With the shaft lock engaged, tighten the chuck
using the EZ Twist nose cap or wrench to secure the
accessory.
HELPFUL TIPS WHEN USING THE DREMEL
CHUCK
• The Dremel chuck and the collet and collet nut
system are interchangeable on this tool. While the
chuck will provide you with the best experience for
changing accessories, the collet and collet nut will
provide a more precise accessory holding solution
especially in heavier side load applications.
• If you find the accessory slipping in the chuck,
use the included EZ Twist nose cap or wrench to
tighten the chuck around the bit. If further slippage
persists, switch to using the collet and collet nut.
• The jaws of the chuck can become displaced
causing the accessory to no longer run true and
concentric (run-out).
To reset the jaws, apply the following procedure:
1. Remove the accessory from the chuck.
2. Clean the chuck.
3. Press shaft lock button and tighten the chuck
until the jaws extend past the outer surface of the
chuck, approximately 3 mm.
4. Push the end of the chuck firmly against a hard flat
surface to be sure the jaws are all seated axially.
5. Continue to hand tighten the chuck until the jaws
completely close.
6. Loosen the chuck, and reinsert a straight
accessory.
7. Turn the tool by hand and observe if there is any
runout. If there is obvious run-out, repeat the
procedure.
8. With the shaft lock engaged, tighten the chuck
using the EZ Twist nose cap or wrench to
secure the accessory.
9. Turn the tool on to the lowest speed setting and
observe for run-out. If there is obvious run-out,
check that the accessory is straight before repeating
the procedure.
BALANCING ACCESSORIES
A q
For precision work, it is important that all accessories
be in good balance (much the same as the tires on
your automobile). To true up or balance an accessory,
slightly loosen collet nut and give the accessory or
collet a 1/4 turn. Re tighten collet nut and run the
rotary tool.
You should be able to tell by the sound and feel if your
accessory is running in balance. Continue adjusting in
this fashion until best balance is achieved.
