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.
On the Model 750, there is a LO and HI switch. When
the switch indicator is in position 1 or LO, the tool runs
at about 6,500 RPM. When the switch indicator is in
position 2 or HI, the tool runs at about 13,000 RPM.
On Model 754, there is a LO and HI switch. When the
switch is in position 1 or LO, the tool runs at about
5,000 RPM. When the switch is in position 2 or HI, the
tool runs at about 10,000 RPM.
On the Model 770, there is a LO and HI switch. When
the switch indicator is in position 1 or LO, the tool runs
at about 10,000 RPM. When the switch indicator is in
position 2 or HI, the tool runs at about 20,000 RPM.
You can refer to the charts on pages 14 and 15 to
determine the proper speed, based on the material
being worked and the type of cutter or other 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 speed of Models 750, 754 & 770 is controlled by
setting this indicator on the housing.
Sharpener, and the 1453 Chainsaw Sharpener attach-
ment.
Use of other Dremel attachments not listed is not rec-
