If using the screw mandrel:
 Align desired accessory hole with mandrel screw head.
 Screw accessory onto mandrel by twisting clockwise until
secure.
If using the drum mandrel:
 Align appropriate sized sanding drum over mandrel and
push down to completely cover drum end of mandrel.
NOTE: If necessary, tighten the screw on the drum
mandrel head to expand the drum and securely hold the
sanding drum in place.
BALANCING ACCESSORIES
For precision work, it is important that all accessories be
properly balanced. To balance an accessory, slightly loosen
the collet nut and give the accessory or collet a 1/4 in. turn.
You should be able to tell by the sound and feel if the accessory
is running in balance. Continue adjusting in this fashion until
the best balance is achieved. Replace accessories if they
become damaged or unbalanced.
TURNING THE ROTARY TOOL ON/OFF
See Figure 8, page 13.
To turn the rotary tool ON, depress the on/off switch in the
center of the pen's handle. To turn it OFF, press the on/off
switch again.

SELECTING THE RIGHT SPEED
See Figure 8, page 13.
The rotary tool has a speed range of 4,400-23,000/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 num-
bered 1 to 5 and MAX. For example, a speed setting of 1 is
approximately 4,400 RPM, and a speed setting of MAX is
approximately 23,000 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.
