(2) Push up the base tip and jog the base back and
forth. (Fig. 11)
(3) You can adjust the base position in three stages.
Move the base at an interval of about 15 mm,
find the position where the base hooks, and
press in the base lever with your fingers. The
base is secured when you hear the clicking
sound. (Fig. 12)
9. Adjusting the blade reciprocating speed
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. 13)
(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.
CAUTION:
⅜ When cutting at low speed (scale of 1 – 2), never cut a wooden board more than
25/64" (10 mm) thick or a mild steel plate more than 5/64" (2 mm) thick. The load on
the motor can result in overheating and damage.
⅜ Although this unit employs a powerful motor, prolonged use at a low speed will
increase the load unduly and may lead to overheating. Properly adjust the saw blade
to allow steady, smooth cutting operation, avoiding any unreasonable use such as
sudden stops during cutting operation.
