SAFETY INSTRUCTIONS FOR SAWS WITH
PENDULUM GUARD OR TOW GUARD
a) Check lower guard for proper closing before each use.
Do not operate the saw if lower guard does not move
freely and close instantly. Never clamp or tie the lower
guard into the open position.
If saw is accidentally dropped, lower guard may be
bent.
Raise the lower guard with the retracting handle
and make sure it moves freely and does not touch
the blade or any other part, in all angles and depths
of cut.
b) Check the operation of the lower guard spring. If the
guard and the spring are not operating properly, they
must be serviced before use.
Lower guard may operate sluggishly due to damaged
parts, gummy deposits, or a build-up of debris.
c) Lower guard should be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise lower guard by retracting handle and as
soon as blade enters the material, the lower guard
must be released.
For all other sawing, the lower guard should operate
automatically.
d) Always observe that the lower guard is covering the
blade before placing saw down on bench or floor.
An unprotected, coasting blade will cause the saw
to walk backwards, cutting whatever is in its path.
Be aware of the time it takes for the blade to stop
after switch is released.

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 model C7YA, the saw blades range should be
from 185 mm to 184 mm.
12. Disconnect the plug from the receptacle before
carrying out any adjustment, servicing or
maintenance.
13. Do not use any abrasive wheels.

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 work piece, place the work piece on
the workbench prior to cutting. If a square block
is utilized as the workbench, adjust leveling to ensure
that it is properly stabilized. An unstable workbench
will result in hazardous operation.
