Operation Guidelines
Variable Speed Trigger
The saw is equipped with a variable speed trigger, allowing you to control the cutting speed from 0 to 3000 strokes per minute (SPM). This feature provides increased blade control and enables you to match the speed to the specific application and material being cut.

This diagram points out the variable speed trigger, which allows users to adjust the cutting speed from 0 to 3000 strokes per minute for optimal control.

Pivoting Shoe
The pivoting shoe provides leverage during cutting, which helps to extend blade life and allows for better depth-of-cut control. This feature is particularly useful when cutting through various materials or in awkward positions.

The 1-1/8 inch stroke length of the blade ensures fast and efficient cutting.
