• A variable speed dial is located on the upper arm of the saw for pre-setting maximum speed. Rotate the dial to adjust the maximum strokes per minute.

Cutting Techniques

• Always allow the blade to reach full speed before engaging the workpiece.
• Apply steady, even pressure. Do not force the tool, as this can lead to blade breakage or reduced cut quality.
• For plunge cuts, tilt the saw forward onto the front edge of the shoe, start the saw, and slowly pivot the tool down until the blade cuts through the material.

Using the LED Work Light

• The integrated LED light illuminates the work area when the trigger is depressed, improving visibility of the cut line.
