FUNCTIONAL DESCRIPTION

CAUTION:
• Always be sure that the tool is switched off and
unplugged before adjusting or checking function on the
tool.
Switch action (Fig.1)
CAUTION:
• Before plugging in the tool, always check to see that
the switch trigger actuates properly and returns to the
"OFF" position when released.
To start the tool, simply pull the trigger. Release the
switch trigger to stop.
For continuous operation, pull the switch trigger and then
push in the lock button.
To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Speed adjusting dial (Fig. 2)
The tool speed can be infinitely adjusted between
1.0 m/s and 1.7 m/s by turning the adjusting dial. Higher
speed is obtained when the dial is turned in the direction
of number 5; lower speed is obtained when it is turned in
the direction of number 1.
Select the proper speed for the workpiece to be cut.
CAUTION:
• The speed adjusting dial can be turned only as far as 5
and back to 1. Do not force it past 5 or 1, or the speed
adjusting function may no longer work.
Lighting up the lamps (Fig. 3)
CAUTION:
• Do not apply impact to the light, which may cause dam-
age or shorted service time to it.
To turn on the lamp, press the "I"(ON) side of the lamp
switch. Press the "O"(OFF) side to turn it off.
NOTE:
• Use a dry cloth to wipe the dirt off the lens of lamp. Be
careful not to scratch the lens of lamp, or it may lower
the illumination.
• Do not use thinner or gasoline to clean the lamp. Such
solvents may damage it.
• After operation, always turn off the light by pressing
the "O (OFF)" side.

ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing the blade
CAUTION:
• Oil on the blade can cause the blade to slip or come off
unexpectedly. Wipe off all excess oil with a cloth before
installing the blade.
• Use caution when handling the blade so that you are
not cut by the sharp edge of the blade teeth.
Turn the blade tightening lever clockwise until it hits
against the protrusion on the frame. (Fig. 4)
Match the direction of the arrow on the blade to that of
the arrow on the wheels.
Insert the blade between the bearings of one blade guide
first and then into the other blade guide. The blade back
should contact the bearings in the lower portion of the
blade guides. (Fig. 5)
Position the blade around the wheels and insert the other
side of the blade within the upper holder and lower holder
until the blade back contacts the bottom of the upper
holder and lower holder.
Hold the blade in place and turn the blade-tightening
lever counterclockwise until it hits against the protrusion
on the frame. This places proper tension on the blade.
Make sure that the blade is correctly positioned within the
blade guard and around the wheels.
Start and stop the tool two or three times to make sure
that the blade runs properly on the wheels. (Fig. 6)
CAUTION:
• While making sure that the blade runs on the wheels
properly, keep your body away from the blade area.
To remove the blade, follow the installation procedure in
reverse.
CAUTION:
• When turning the blade tightening lever clockwise to
release the tension on the blade, point the tool down-
ward because the blade may come off unexpectedly.
Adjusting the protrusion of stopper plate (Fig. 7)
In the ordinary operation, protrude the stopper plate to
the A side fully.
When the stopper plate strikes against the obstacles like
a wall or the like at the finishing of a cut, loosen two
screws and slide it to the B side in the figure. After sliding
the stopper plate, secure it by tightening two screws
firmly.
