NOTE
Values of the inclined gauge provided on the base
merely serve as a rough guideline. For cutting
operation at an inclined posture, use the circular
saw after adjusting the angle between the base and
the saw blade with a protractor, etc.
3. Regulating the guide (Fig. 16)
The cutting position can be regulated by moving
the guide to the left or right after loosening its knob
bolt. The guide may be mounted on either the right
or left side of the tool.

4. Fine tuning of parallelism
It is possible to fine-tune the parallelism of the saw
blade to the base using the parallelism adjustment
screw.
Adjustment has already been made at the time of
shipment from the factory. However, in the unlikely
event of parallelism being faulty, adjust as follows.
(1) Unfasten only the mounting screws of the saw
cover hinge portion (Fig. 17).

(2) Retract the lower guard into the saw cover.
(3) Insert wood chip in the rear side of the saw
blade base, and mark the position on the base
(Fig. 18).

(4) Move the marked wood chip to the front of the
base, and turn the parallelism adjustment screw
so that the marking corresponds to the base side
(Fig. 19).

NOTE
After parallelism adjustment, if the saw cover hinge
portion is loose, tighten the M5 U-Nut. Do not over
tighten the nut as this may result in deformation
of the bevel plate.
(5) After adjustment, fasten the mounting screws
tightly in place.
NOTE
Parallelism may be slightly faulty if the cutting
depth is adjusted after parallelism adjustment.
5. Adjusting the guide piece
On the circular saw, it is possible to make fine
adjustment of the fixing position of the guide piece,
where the saw blade and the premarked line are
to be aligned.
When the saw is shipped from the factory, the
linear portion of a front scale on the guide piece
is aligned with the central position of the saw blade
(Fig. 20).
