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, inviting 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.
CAUTION:
Damaged cord must be replaced or repaired.
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 POWER TOOL 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. After
adjustment, ensure that that riving knife moves in
accordance with the adjusted cutting depth.
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 wing bolt.
The guide can be mounted on either the left or the
right sides.
CUTTING PROCEDURES
1. Place the saw body (base) on the lumber, and align
the marked off line with the saw blade by use of the
front scale. When the saw blade is not inclined, the
right-hand side is the reference (Fig. 6 (A)); when the
saw blade is inclined (45°), the left-hand side (marked
"45" on the base) is the reference (Fig. 6 (B)).
2. Turn ON the switch before the saw blade contacts the
lumber. The switch is turned ON when the trigger is
squeezed, and turned OFF when the trigger is
released.
3. Moving the saw straight at a constant speed will
produce optimum cutting.
CAUTIONS:
Before starting to saw, confirm that the saw blade
has attained full-speed revolution.
