PRECAUTIONS ON USING CIRCULAR SAW
1. Do not use saw blades which are deformed or
cracked.
2. Do not use saw blades made of high speed steel.
3. Do not use saw blades which do not comply with
the characteristics specified in these instructions.
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.
8. Ensure that the retraction mechanism of the guard
system operates correctly.
9. Never operate the circular saw with the saw blade
turned upward or to the side.
10. Ensure that the material is free of foreign matters
such as nails.
11. For models C9SA2 and C9BA2, the saw blades
should be 235 mm.
12. For model C9BA2, be careful of brake kickback.
C9BA2 model features an electric brake that
functions when the switch is released. As there
is some kickback when the brake functions, be
sure to hold the main body securely.
13. Sparks can sometimes appear caused by braking
operation when the switch is turned off since
C9BA2 model employ electric brakes. Be informed,
however, that this phenomenon is not a machine
trouble.
14. For model C9BA2, when the brake becomes
ineffective, replace the carbon brushes with new
ones.
15. Disconnect the plug from the receptacle before
carrying out any adjustment, servicing or
maintenance.

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.
5. When using the side handle (Fig. 2)
Securely attach the side handle to the base with
the two flat head screws (M6
× 16) when using the
side handle.
CAUTION
To avoid possible accident, always ensure that the
portion of lumber remaining after cutting is securely
anchored or held in position.
