PRIOR TO OPERATION
1. Power source
Ensure that the power source to be utilized con-
forms 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.

such as nails.
11. For model C7ST, the saw blades range should be
from 185 mm to 180 mm.

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 se-
curely anchored or held in position.
ADJUSTING THE POWER TOOL PRIOR TO USE
1. Adjusting the cutting depth
To adjust cutting depth, loosen the lever (A) and,
while holding the base with one hand, move the
main body up and down to obtain the prescribed
cutting depth. After adjusting to the prescribed cutting
depth, tighten the lever (A) securely (Fig. 2).
CAUTION
Should this lever (A) remain loosened, it will create a
very hazardous situation. Always thoroughly clamp it.
2. Adjusting the angle of inclination
By loosening the lever (A) at the scale, the saw
blade can be inclined up to maximum angle of 45°
against the base.
The angle of inclination can also be regulated by
loosening the lever (A) at the scale (Fig. 3).
CAUTION
It is very hazardous to allow this lever (A) to remain
loosened. Always thoroughly clamp it.
