4. Do not stop the saw blades by lateral pressure
on the disc.
5. Always keep the saw blades sharp.
6. Ensure that the lower guard moves smoothly
and freely.
7. Never use the circular saw with its lower guard
fixed in the open position.

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 angle of inclination
As shown in Fig. 3 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.
3. Regulating the guide
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.
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.
