TURNING THE ROTARY TOOL ON/OFF
See Figure 7, page 16.
 To turn the tool ON: push the ON/OFF ( I/O ) switch to
the ON ( I ) position.
 To turn the tool OFF: push the ON/OFF ( I/O ) switch to
the OFF ( O ) position.
SELECTING THE RIGHT SPEED
See Figures 7 - 8, page 16.
The rotary tool has a speed range of 5,000 to 35,000/min
RPM. 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.
Use the indicator mark above the speed control dial to set the
best speed for the job. The speed control dial is numbered
1 to 3. The speeds for each setting are:
 Speed (1)........................................................5,000 RPM
 Speed (2)......................................................15,000 RPM
 Speed (3)......................................................35,000 RPM
Refer to the Application Speed Recommendations table
to determine the proper speed based on the material being
worked and the type of accessory being used.

SLOWER SPEEDS
Certain materials, some plastics for example, require a
relatively slow speed because the friction of the tool generates
heat and causes the plastic to melt at high speed.
Slow speeds (15,000 RPM or less) are usually best for
polishing operations using the polishing accessories. They
may also be best for working on delicate projects, delicate
wood carving, and fragile model parts.
Higher speeds are better for carving, cutting, and shaping
wood.
Hardwoods, metals, and glass require high speed operation.
Drilling should also be done at high speeds.
To determine the optimum operational speed for different
materials and accessories, refer to the Application Speed
Recommendations table, on the next page. Look this table
over and become familiar with it.
The best way to determine the correct speed for work on
any material is to practice for a few minutes on a piece of
scrap, even after referring to the table. You can quickly
learn that a slower or faster speed is more effective just by
observing what happens when you make a pass or two at
Aluminum,
Steel
Brass, Etc.
