Note: Use of power adapters or battery packs not sold by
Dremel may void the warranty.
ELECTRONIC MONITORING
Your tool is equipped with an internal electronic monitoring
system that helps to maximize motor and battery
performance by limiting the current to the tool when
overload and stall conditions occur. If you stall the tool for
too long, or bind the bit in a work piece, especially at high
speeds, the tool will automatically turn itself off thanks to
the fallback built into it. Once this happens, slide lever to
"0" position, simply take the tool out of the material you
were stalled in, turn it back on again, adjust the speed
if necessary, and continue using it. When the battery is
close to empty, the tool may shut down automatically
more frequently than normal. If this happens, it is time to
recharge the tool.
ACCESSORIES
ALWAYS TURN OFF THE TOOL BEFORE CHANGING
ACCESSORIES

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.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock engaged twist nose cap clockwise

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.

BALANCING ACCESSORIES
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.
The Dremel tool can be equipped with DREMEL
attachments. Please find the compatibility list on page 8.

GETTING STARTED
The first step in using the multitool is to get the "feel" of it.
Hold it in your hand and feel its weight and balance. Feel
the taper of the housing. This taper permits the tool to be
grasped much like a pen or pencil.
IMPORTANT! Practice on scrap material first to see how
the tool's high-speed action performs. Keep in mind that
your multitool will perform best by allowing the speed,

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
