Speed change
To adjust the tool speed, turn the speed change dial. The tool speed can be adjusted between 1,000 and 3,000 strokes per minute.
The reference table on the right denotes the relationship between the number set- tings on the speed change dial and the approximate strokes per minute a t that setting.
Refer to the table on the right to select suggested speed for the workpiece to be cut. However, proper speed may differ depending upon the type or thickness of the workpiece.

In general, higher speeds will allow you to cut a workpiece faster but the service life of the blade will be reduced.
CAUTION :
Adjust the speed change dial only within the range of numbers 1 through 6. Do not force the dial beyond this range.
