Using The Cordless Rotary Tool; Important Charging Notes - Dremel 7700 Operating/Safety Instructions Manual

Important Charging Notes

If you anticipate long periods of non-use for your tool
it's best to unplug your charger and battery pack from
its power source. Unplugging the charger will extend
the life expectancy of the charger and battery pack.

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.
The battery pack accepts only about 80% of its maxi-
mum charge capacity with its first charge; or, after pro-
longed storage it will also require additional time on the
first charge. However, after several charge and dis-
charge cycles, the batteries should be up to full charge
capacity and delivering maximum performance.
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. Con -
centrate on guiding the tool over the work using very lit-
tle 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 effi cient work out of
the accessory.
