For best control in close work, grip the Rotary Tool

Operating Speeds For Accessories
Set the speed indicator to fit the job to achieve the
best job results when working with different
materials.
To select the right speed for each job, use a practice
piece of material. Vary speed to find the best speed
for the accessory you are using and the job to be
done.
Your Cordless RotaryTool is equipped with a variable
speed control dial. To turn the tool ON, rotate dial to
desired number to select the operating speed needed
from 5,000 – 25,000 RPM. To turn tool OFF, rotate
dial to the "0" off position.
You can refer to the charts on page 13, 14, and 15 to
determine the proper speed, based on the material
being worked and the type of accessory being used.
These charts enable you to select both the correct
accessory and the optimum speed at a glance.
Needs for Slower Speeds
Certain materials, however, (some plastics, for ex-
ample) require a relatively slow speed because at high
speed the friction of the tool generates heat and caus-
es the plastic to melt.
Most work is done at high speed on your Cordless
Rotary Tool. Lower speeds are needed only for certain
tasks.

The "handgrip" method of holding the tool is used for
operations such as grinding a flat surface or using
cutoff wheels.
The speed of Model 780 is controlled by rotating this
dial to desired setting on dial.
