This unit has a built-in electronic control
circuit that makes it possible to adjust the
variable speed of the saw blade either
both by pulling a switching trigger or
turning a dial. (Fig. 15)

(1) If you pull the trigger further in, the
speed of the blade accelerates. Begin
cutting at a low speed to ensure the
accuracy of your target cut position.
Once you've obtained a sufficient
cutting depth, increase the cutting
speed.
(2) On the dial scale, "5" is the maximum
speed and "1" the minimum. The high
speed is generally suitable for soft
materials such as wood, and the low
speed is suitable for hard materials
such as metal. We recommend that
you use the following as a rough guide
in selecting the suitable speed for the
materials you are cutting.
Example of materials
to be cut
Mild steel pipes /
