The speed is infinitely variable from 8,000 to
-1
24,000 min
dial (19) for uniform cutting results in all types of
wood, plastics and in aluminium.
Turn the electronic speed control dial to the
required level.
Generally, use the low setting for large diameter
cutters and the high setting for small diameter
cutters. The correct setting, however, is a matter
of experience.
1 = 8,000 min
2 = 9,500 min
3 = 11,500 min
4 = 16,000 min
5 = 19,500 min
6 = 22,500 min
7 = 24,000 min
