APPLICATION
Cutting various types of wood.
PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized conforms
to the power requirements specified on the product
nameplate.
2. Power switch
Ensure that the power switch is in the OFF position.
If the plug is connected to a receptacle while the
power switch is in the ON position, the power tool
will start operating immediately, which could cause
a serious accident.
3. Extension cord
When the work area is removed from the power
source, use an extension cord of sufficient thickness
and rated capacity. The extension cord should be
kept as short as practicable.
4. Prepare a wooden workbench (Fig. 1)
Since the saw blade will extend beyond the lower
surface of the lumber, place the lumber on a
workbench when cutting. If a square block is utilized
as a workbench, select level ground to ensure it
is properly stabilized. An unstable workbench will
result in hazardous operation.
CAUTION
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.

ADJUSTING THE SAW PRIOR TO USE
1. Adjusting the cutting depth
As shown in Fig. 2, hold the handle with one hand
while loosening the knob with the other.
The cutting depth can be adjusted by moving the
base to the desired position. In such manner adjust
the cutting depth and then securely retighten the
knob.
2. Adjusting the riving knife
Loosen the hexagonal – head bolt used to clamp
the riving knife, adjust the riving knife to the position
shown in Fig. 3 and securely retighten the bolt.
3. Adjusting the angle of inclination
As shown in Fig. 4 (A), Fig. 4 (B) by loosening the
knob on the incline gauge and the wing-bolt on the
base, the saw blade may be inclined to a maximum
angle of 45° in relation to the base. After having
completed the adjustment, reconfirm that the knob
and the wing bolt are firmly tightened.
4. Regulating the guide (Fig. 5)
The cutting position can be regulated by moving
the guide to the left or right after loosening its
wingbolt. The guide may be mounted on either the
right or left side of the tool.
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. 6)
Loosen the fixed screw on the guide piece, should
the fixing position be wrong, and make necessary
adjustment of the position.
CUTTING PROCEDURES
1. Place the base on the material, then align the
premarked line and the sawblade with the guide
piece front scale section at the front of the base.
(Fig. 6)
When the base is not slanted, use the large cutout
as the guide. (Fig. 6, Fig. 7(A))
If the base is slanted (45 degrees), use the small
front scale as the guide. (Fig. 6, Fig. 7(B))
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.
