2. Horizontal vise (optional accessory)
(Fig. 22 & 23)
The horizontal vise can be installed on either the left
or right side of the base. By turning the vise knob
counterclocwise, the screw is released and the vise
shaft can be moved rapidly in and out. To grip work-
pieces, turn the vise knob gently clockwise until the
projection reaches its topmost position, then fasten
securely. If the vise knob is forced in or pulled out
while being turned clockwise, the projection may
stop at an angle. In this case, turn the vise knob
back counterclockwise until the screw is released,
before turning again gently clockwise. The maximum
width of workpieces which can be secured by the
horizontal vise is 122 mm.
3. Holders and holder assembly (optional accessory)
The holders and the holder assembly can be
installed on either side as a convenient means of
supporting workpieces horizontally. Install them as
shown in Fig. 24. Then tighten the screws firmly to
secure the holders and the holder assembly.
(Fig. 24)
When cutting long workpieces, use the holder-rod
assembly (optional accessory). It consists of two
holder assemblies and two rods 12. (Fig. 25)
CAUTION:
Always support long workpieces level with the top
surface of the turn base for accurate cuts and to pre-
vent dangerous loss of control of the tool.
Switch action (Fig. 26)
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.
• When not using the tool, remove the lock-off button and
store it in a secure place. This prevents unauthorized
operation.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, press in the lock-off button and pull the
trigger. Release the switch trigger to stop.
Lock lever (Fig. 27)
For European countries only
When cutting, push the lock lever to the left to release the
handle from the raised position. When the cut is com-
pleted, release the lock lever after returning the blade to
its fully elevated position. The handle will be automati-
cally locked in the raised position.
Operation
CAUTION:
Do not apply excessive pressure on the handle when cut-
ting. Too much force may result in overload of the motor
and/or decreased cutting efficiency.
Press cutting (Fig. 28)
1.
• Workpieces up to 61 mm high x 122 mm wide can
be cut in the following way.
• Secure the workpiece with the vise. Switch on the
tool and wait until the blade attains full speed
before lowering gently into the cut. When the cut is
completed, switch off the tool and WAIT UNTIL
THE BLADE HAS COME TO A COMPLETE STOP
before returning the blade to its fully elevated posi-
tion.
2. Miter cutting
Refer to the previously covered "Positioning for
adjusting the miter angle".
Bevel cut (Fig. 29)
3.
• At a left 45° bevel angle, workpieces up to 45 mm
high x 122 mm wide can be cut.
• Loosen the lever and tilt the saw blade to set the
bevel angle. Refer to the previously covered "Posi-
tioning for adjusting the bevel angle". Secure the
workpiece with the vise. Switch on the tool and
wait until the blade attains full speed. Then gently
lower the handle to the fully lowered position while
applying pressure in parallel with the blade. When
the cut is completed, switch off the tool and WAIT
UNTIL THE BLADE HAS COME TO A COM-
PLETE STOP before returning the blade to its fully
elevated position.
CAUTION:
• During a bevel cut, it may create a condition
whereby the piece cut off will come to rest against
the side of the blade. If the blade is raised while
the blade is still rotating, this piece may be caught
by the blade, causing fragments to be scattered
around which is dangerous. The blade should be
raised ONLY after the blade has come to a com-
plete stop.
• When pressing down the handle, apply pressure in
parallel with the blade. If a force is applied perpen-
dicularly to the turn base or if the pressure direc-
tion is changed during a cut, the precision of the
cut will be impaired.
4. Compound cutting
Compound cutting is the process in which a bevel
angle is made at the same time in which a miter
angle is being cut on a workpiece. Compound cut-
ting can be performed at angle shown in the table
below.
Miter angle
Left and right 45°
Left and right 52°
At the miter angle of left 45° and bevel angle of left
45°, workpieces 45 mm high x 85 mm wide can be
cut. When performing compound cutting, refer to
"Press cutting", "Miter cutting" and "Bevel cut" expla-
nations.
Bevel angle
Left 0° – 45°
Left 0° – 40°
