Speed adjusting dial
CAUTION: The speed adjusting dial is not for
using low speed rated blades but for obtaining a
speed which is suitable to material of workpiece.
Useonlybladeswhichareratedforatleastthemaxi-
mumnoloadspeedstatedintheSPECIFICATIONS.
CAUTION:Thespeedadjustingdialcanbe
turned only as far as 6 and back to 1. Do not force it
past 6 or 1, or the speed adjusting function may
no longer work.
Thetoolspeedcanbeadjustedbyturningtheadjusting
dial. Higher speed is obtained when the dial is turned in
the direction of number 6; lower speed is obtained when
it is turned in the direction of number 1.
Refer to the table to select the proper speed for the
workpiece to be cut. However, the appropriate speed
may differ with the type or thickness of the workpiece. In
general, higher speeds will allow you to cut workpieces
faster but the service life of the blade will be reduced.
