Balancing Accessories
For precision work, it is important that all accesso-
ries be properly balanced. To balance an accesso-
ry, slightly loosen the collet nut and give the
accessory or collet a 1/4 in. turn.
Retighten collet nut and run the rotary tool. You
H
should be able to judge 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.
Speed Control
The rotary tool has a speed range of 10000 to
35,000 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 (H) to set the best speed
for the job. The speed control dial (H) is numbered
from 1 to Max. For example, a speed setting of 1 is approximately 10,000 RPM, and
a speed setting of Max is approximately 35,000 RPM.
Refer to the Speed Dial Settings table to determine the proper speed based on the
material being worked and the type of accessory being used.
