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.
For best control in close work, grip the
Rotary Tool like a pencil between your
thumb and forefinger.
The “handgrip” method of holding the tool
is used for operations such as grinding a
flat surface or using cutoff wheels.
USING THE CORDLESS ROTARY TOOL
The first step in learning to use the Cordless
Rotary Tool 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.
When you turn on the tool for the first time,
hold it away from your face. Accessories can
be damaged during handling, and can fly apart
as they come up to speed. This is not
common, but it does happen.
Practice on scrap materials first to see how the
Cordless Rotary Tool cuts. Keep in mind that
the work is done by the speed of the tool and
by the accessory in the collet. You should not
lean on or push the tool into the work.
Instead, lower the spinning accessory lightly to
the work and allow it to touch the point at
which you want cutting (or sanding or etching,
etc.) 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 best to make a series of passes
with the tool rather than attempt to do all the
work in one pass. To make a cut, for example,
pass the tool back and forth over the work,
much as you would a small paint brush. Cut a
little material on each pass until you reach the
desired depth. For most work, the deft, gentle
touch is best. With it, you have the best
control, are less likely to make errors, and will
get the most efficient work out of the
accessory.
