Fig.3
CAUTION:
Before inserting the battery cartridge into the tool,
•
always check to see that the switch trigger actuates
properly and returns to the "OFF" position when
released.
To prevent the switch trigger from accidentally pulled, the
lock-off button is provided.
To start the tool, depress the lock-off button from B side
and pull the switch trigger.
Release the switch trigger to stop. After use, always
press in the lock-off button from A side.
Speed adjusting dial
Fig.4
The tool speed can be infinitely adjusted between 1.4
m/s and 2.7 m/s by turning the adjusting dial. Higher
speed is obtained when the dial is turned in the direction
of number 6; 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 6 and back to 1. Do not force it past 6 or 1, or the
speed adjusting function may no longer work.
Lighting up the lamp
Fig.5
CAUTION:
Do not apply impact to the lamp, which may cause
•
damage or shorted service time to it.
Pull the switch trigger to light up the lamp. The lamp
keeps on lighting while the switch trigger is being pulled.
The lamp goes out 10 -15 seconds after releasing the
trigger.
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.
When the tool is overloaded during operation, the
•
lamp flickers.
When the remaining battery capacity becomes
•
small, the lamp flickers.
ASSEMBLY
CAUTION:
Always be sure that the tool is switched off and the
•
battery cartridge is removed 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.6
Match the direction of the arrow on the blade to that of
the arrow on the wheels.
Fig.7
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.
Fig.8
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.
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
downward because the blade may come off
unexpectedly.
Adjusting the protrusion of stopper plate
Fig.9
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.
