For best control in close work, grip the Rotary Tool
like a pencil between your thumb and forefinger.
Set the speed indicator to fit the job to achieve the
best job results when working with different
ma te rials.
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 7300, 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 14,000 RPM.
You can refer to the charts on pages 16 and 17 to deter-
mine the proper speed, based on the materi al being
worked and the type of cutter or other accessory being
used. These charts enable you to select both the cor-
rect acces sory 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.
Operating Speeds For Accessories
The "handgrip" method of holding the tool is used for
operations such as grinding a flat surface or using
cutoff wheels.
Most work is done at high speed on your Cordless
Rotary Tool. Lower speeds are needed only for certain
tasks.
The speed of Model 7300 is controlled by
setting this indicator on the housing.
