tool automatically turns off due to overload conditions, the
switch must be turned off for a few seconds to allow the
circuit to reset before continuing use.
CHARGING BATTERY PACK
1. Plug charger cord into your standard power outlet. With
no battery pack inserted, the charger's green indicator
light will go ON. This indicates the charger is receiving
power and the charger is ready for operation.
2. To remove the battery pack from the tool press both
battery release tabs and pull the battery from the tool.
3. When you insert the battery pack into the charger, the
charger's green indicator light will begin to "BLINK".
This indicates that the battery is receiving a fast
charge.
4. When the indicator light stops "BLINKING" (and
becomes a steady green light) fast charging is
complete. The battery pack is fully charged and can be
removed from the charger. The light will stop blinking
in less time if the battery pack was not completely
discharged.
5. When you begin the charging process of the battery
pack, a steady green light could also mean the battery
pack is too hot or too cold. Fast charging is only
possible when the temperature range of the battery
pack is between 0°C and 45°C. As soon as the
battery pack reaches the correct temperature range,
the battery charger will automatically switch to fast
charging.
6. The battery pack may be used even though the light
may still be blinking. The light may require more time
to stop blinking depending on temperature.
7. A substantial drop in operating time per charge may
mean that the battery pack is nearing the end of its life
and should be replaced.
8. Remember to unplug charger during storage period.
ACCESSORIES
ALWAYS TURN OFF THE TOOL BEFORE CHANGING
ACCESSORIES
Use only Dremel tested, high performance accessories.
Be sure to read the instructions supplied with your
Dremel accessory for further information on its use.
Handle and store accessories carefully to avoid
chipping and cracking.
CHANGING ACCESSORIES
A. Collet nut
B. Collet (3.2 mm)
C. Nose cap (EZ Twist integrated wrench*)
D. Dremel chuck 4486*
E. Shaft lock button
F. Wrench
*) not standard included
1. Press the 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.
2. With the shaft lock engaged, loosen (do not remove)
the collet nut. Use the collet wrench if necessary.
3. Insert the bit or accessory shank fully into the collet.
4. With the shaft lock engaged, tighten the collet nut.
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
to tighten the collet nut.
5. Screw the nose cap back into its original position.
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
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.
