Fig.3:

1. Lever

This tool can be operated with an orbital or a straight-line cutting action. To change the cutting action, turn the lever to the desired cutting action position. Refer to the table to select the appropriate cutting action.

NOTE:
Orbital action means that the saw blade moves up and down, and back and forth at the same time. This increases the efficiency of cutting.

Speed adjusting dial Fig.4:

1. Speed adjusting dial

The strokes per minute can be adjusted just by turning the speed-adjusting dial. This can be done even while the tool is running. The dial is marked 1 (lowest speed) to 5 (full speed). Turn the speed adjusting dial between 1 and 5 according to your work. Refer to the table to select the proper speed for the workpiece to be cut. However, the appropriate application may differ with the shape and hardness of the workpiece. In general, orbital cutting action is suitable for soft materials.

NOTE:
Orbital cutting action is suitable for most soft materials such as wood, however, sometimes not, according to the shape or the hardness of the workpiece, etc.

The number   on the   adjusting dial| Strokes per minute
---|---
5| 3,000
4| 2,500
3| 2,000
2| 1,500
1| 1,000
The workpiece to be cut| The number   on the  adjusting dial
---|---
Wood| 5
Autoclaved lightweight

concrete

| 4 – 5
Iron pipes, cast iron pipes, and aluminum| 2 – 4
Plastics| 1 – 3
