⅜ Avoid any unreasonably forced pressure to the motor during cutting operation by
twisting or pressing the circular saw forcibly;
⅜ Avoid any use of dull saw blade.
3. Cutting procedures
CAUTION:
● Recheck that the saw blade is se-
curely clamped.
● Confirm that the clamp lever for ad-
justing the slot depth, the wing-bolt
(A) for adjusting the angle of inclina-
tion.
(1) Place the saw body (base) on the lumber, and as in Fig. 18 align the intended line of cut
with the saw blade, using the notch at the front of the base. This relationship of base to
lumber should remain unchanged regardless of the inclination of the base.
(2) Ensure that the switch is turned to the ON position before the saw blade comes in contact
with the lumber. The switch is turned ON when the trigger is squeezed; and OFF when
the trigger is released.
(3) Moving the saw straight at a constant speed will produce optimum cutting.
CAUTION:
● Before starting to saw, ensure that the saw blade has reached full speed revolution.
● Should the saw blade be stopped or made an abnormal noise during operation, turn
off the switch immediately.
● When finished with a job, pull out the battery from the main body.
● Twisting and forcibly pressing the saw during cutting can result in unreasonable
pressure on the motor, so try to go straight quietly.
● In the situation where the circular saw is continuously operated while replacing the
battery with stocked spare batteries one after another, the motor tends to overheat.
Therefore, whenever the housing becomes hot, give the saw a break for a while.
● Avoid cutting operation in a state where the base bottom is afloat from the material
being cut. Otherwise, the motor can get locked.
