Important Charging Notes
1. The charger was designed to fast charge the
battery only when the battery temperature is between
40˚F (4˚C) and 105˚F (41˚C).
2. 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.
3. If battery does not charge properly:
a. Check for voltage at outlet by plugging in
some other electrical device.
b. Check to see if outlet is connected to a light
switch which turns power “off” when lights are turned
off.
c. Check battery pack terminals for dirt. Clean
with cotton swab and alcohol if necessary.
d. If you still do not get proper charging, take or
send tool, battery pack and charger to your Dremel
Service Center.
Note: Use of chargers or battery packs not sold by
Dremel may void the warranty.
Read the next sections carefully. They will help you use
your Cordless Rotary Tool correctly and help you select
the correct accessory for your job.
Stall Protection
This tool has a stall protection feature built into it to
protect the motor and battery in the event of a stall. If
you stall the tool for too long, or bind the bit in a work
piece, especially at high speeds, it will automatically
turn itself off. Simply take the tool out of the materi-
al you were stalled in, turn it off for 3 seconds, then
turn it back on again to continue using it. When the
battery becomes close to empty, the tool may shut
down automatically more frequent than normal. If
this happens, it is time to recharge the battery.
Fuel gauge
This tool is equipped with a Fuel gauge that tells you
how much charge your battery has. A fully charged
battery is indicated when all three LED lights are
illuminated. As the battery discharges, the lights will
turn off one by one until only one light is on. When
the last light starts "flashing", the battery is almost
empty. When the battery is dead, the tool will auto-
matically turn off. This will be a sudden stop as
opposed to a gradual winding down of the tool.
Simply recharge the battery and reuse.

Charging the Tool
The Cordless Rotary Tool is not fully charged. The tool
is equipped with a removable battery pack. Be sure to
charge pack prior to initial use.
To charge the tool:
1. Put the switch in the “OFF” position.
2. Squeeze release tabs on both sides of battery pack,
and remove pack from back of tool as shown on page 7.
3. Align exterior shape of battery pack with exterior
shape of charger (alignment arrows on battery columm
will point to the two arrows located on charger),
squeeze release tabs, insert battery pack into charger as
shown and release pressure on tabs so it locks in place.
4. Plug charger into the power source. The green L.E.D.
light indicates connection has been made and the
battery pack is charging. Under normal usage the tool
normally requires 3 hours charging time to reach full
capacity. When charging is complete, LED on charger
will turn off.
5. When charging is completed, squeeze release tabs on
battery pack and remove pack from charger.
6. Align exterior shape of battery pack with exterior
shape of the housing of tool as shown. Squeeze release
tabs, insert battery pack into back of tool, and release
pressure on tabs so it locks in place.
It is this high speed, along with its compact size and
wide variety of special accessories and attachments that
makes your Cordless Rotary Tool different from other
power tools. The speed enables it to do jobs low speed
tools cannot do, such as cutting hardened steel, en-
graving glass, etc.
Getting the most out of your Cordless Rotary Tool is a
matter of learning how to let this speed work for you.
