IMPORTANT!
Practice on scrap material first to see how the
tool’s high-speed action performs. Keep in mind that your tool
will perform best by allowing the speed, along with the correct
accessory, do the work for you. Be careful not to apply too much
pressure.
Instead, lower the oscillating accessory lightly to the work
surface and allow it to touch the point at which you want to
begin. Concentrate on guiding the tool over the work using very
little pressure from your hand. Allow the accessory to do the
work.
Usually it is better to make a series of passes with the tool
rather than to do the entire job with one pass. To make a cut, for
example, pass the tool back and forth over the work. Cut a little
material on each pass until you reach the desired depth.
Slide "ON/OFF" switch
The tool is switched "ON" by the slide switch located on the
topside of the motor housing (Picture 7).
TO TURN THE TOOL "ON", slide the switch button forward.
TO TURN THE TOOL "OFF", slide the switch button backward.
Electronic monitoring
Your tool is equipped with an internal electronic monitoring
system that provides a “soft start”, which will reduce the
stresses that occur from a high torque start.
Variable speed slide switch
Your tool is equipped with a variable speed slide switch. The
speed may be adjusted during operation by sliding the switch
back or forth between any one of the settings.
To achieve the best results when working with different
materials, set the variable speed control to suit the job (See
Speed Chart, Picture 10) . To select the right speed for the
accessory in use, practice with scrap material first.
The speed of the cordless oscillating tool is controlled by setting
this slide switch on the housing.

Battery level indicator
This tool is equipped with a battery level indicator 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 becomes close to empty, the tool may shut
down automatically more frequent than normal. If this happens,
it is time to recharge the battery.
When the battery is dead, the tool will automatically turn off.
This will be a sudden stop as opposed to a gradual winding
down of the tool. Simply recharge the battery and reuse.
3 lights – 100% charge remaining
2 lights – 50% charge remaining
1 light – 25% charge remaining
1 “flashing” light - tool is about to shut off
3 “side to side” lights – battery charge is too low to run tool.
Recharge the battery.
3 “flashing” lights – battery is too hot for use.
Turn tool off and let battery cool down before resuming use.
Inserting and releasing battery pack
Release battery pack from tool by pressing on both sides of the
battery release tabs and pull away from housing (Picture 8).
To insert battery, align battery and slide battery pack into tool
until it locks into position. Do not force.

Important charging notes
1. The charger was designed to fast charge the battery only
when the battery temperature is between 32°F (0°C) and
113°F (45°C). If the battery pack is too hot or too cold, the
charger will not fast charge the battery. (This may happen
if the battery pack is hot from heavy use). When the battery
temperature returns to between 32°F (0°C) and 113°F
(45°C), the charger will automatically begin charging.
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. Remember to unplug charger during storage period.
4. 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 local Dremel Service
Center.
Note: Use of chargers or battery packs not sold by Dremel will
void the warranty.
Operating Principle
Due to the oscillating drive the application tool/accessory swings
up to 21000 times per minute for 3.0°. This allows for precise
work in narrow spaces.
Sawing
• Use undamaged faultless saw blades only.
Deformed,
blunt saw blades or saw blades that are otherwise damaged
can break.
