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. After
adjustment, ensure 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 wingbolt.
The guide may be mounted on either the right or left
side of the tool.
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. 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.
CAUTIONS
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.
Always take care in preventing the power cord from
coming near the revolving saw blade.
