Speed adjusting dial
For 4340CT, 4340FCT
Fig.3
The tool speed can be infinitely adjusted between 800
and 2,800 strokes per minute by turning the adjusting
dial. Higher speed is obtained when the dial is turned in
the direction of number 5; 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.
