counterclockwise, allows fine adjustment of the
turntable to the left.
(3) After adjusting to the desired angle, tighten the side
handle.
CAUTION
Always check that the side handle is secured and the
turntable is clamped.
If you attempt angle cutting without clamping the
turntable, then the turntable might shift unexpectedly
causing injuries.
18. Bevel cutting procedures
CAUTION
Ensure that the clamp lever is securely fixed when
beveling.
Please do this if the length of the material being cut
off is more than 25 mm long. Sometimes cutting
cannot be accomplished because the saw blade will
catch on the inside of the lower guard.
(1) Loosen the clamp lever and bevel the saw blade to
the left or to the right. When tilting the motor head to
the right pull the set pin (A) towards the rear.
The clamp lever adopts a latchet system. When
contacting the work bench and the main body, pull
the clamp lever in the direction of the arrow mark as
illustrated in Fig. 24, and change the direction of the
clamp lever.
(2) Adjust the bevel angle to the desired setting while
watching the bevel angle scale and indicator, then
secure the clamp lever.
WARNING
When the workpiece is secured on the left or right
side of the blade, the short cut-off portion will come
to rest on the right or left side of the saw blade. Always
turn the power off and let the saw blade stop
completely before raising the handle from the
workpiece.
If the handle is raised while the saw blade is still
rotating, the cut-off piece may become jammed
against the saw blade causing fragments to scatter
about dangerously.
When stopping the bevel cutting operation halfway,
start cutting after pulling back the motor head to the
initial position.
Starting from halfway, without pulling back, causes
the lower guard to be caught in the cutting groove of
the workpiece and to contact the saw blade.
CAUTION
When cutting a workpiece of 75 mm height in the left
45° bevel cutting position or a workpiece of 50 mm
height in the right 45° bevel cutting position, adjust
the lower limit position of the motor head so that the
gap between the lower edge of the motor head and
the workpiece will be 2 to 3 mm at the lower limit
position (refer to "2. Checking the saw blade lower
limit position" on page 18).
19. Bevel angle fine adjustment
(1) Grip the handle on the motor head and position it at
the bevel angle you need. Temporarily tighten the
clamp lever (Fig. 25).
CAUTION
If not tightened firmly enough the motor head might
suddenly move or slip, causing injuries. Be sure to
tighten the motor head section enough so it will not
move.
(2) When making fine adjustments of the bevel angle, turn
the knob (B) while supporting the handle with your
hand (Fig. 26).
NOTE
Turning knob (B) clockwise, allows fine adjustment of
the main unit to the left (as seen from front).
Turning knob (B) counterclockwise, allows fine
adjustment of the main unit to the right (as seen from
front).
(3) After adjusting to the desired angle, tighten the clamp
lever and clamp the motor head.
CAUTION
Always check that the clamp lever is secured and the
motor head is clamped. If you attempt angle cutting
without clamping the motor head, then the motor
head might shift unexpectedly causing injuries.
20. Compound cutting procedures
Compound cutting can be performed by following the
instructions in 16 and 18 above. For maximum
dimensions for compound cutting, refer to
"SPECIFICATIONS" table.
CAUTION
Always secure the workpiece with the right or left hand
and cut it by sliding the round portion of the saw
backwards with the left hand.
It is very dangerous to rotate the turntable to the left
during compound cutting because the saw blade may
come into contact with the hand that is securing the
workpiece.
In case of compound cutting (angle + bevel) by left
bevel, turn the sub-fence (B) counterclockwise, and
engage in the cutting operation.
In case of compound cutting (angle + bevel) by right
bevel, turn the sub-fence (A) clockwise, and engage
in the cutting operation.
21. Cutting long materials
When cutting long materials, use an auxiliary platform
which is the same height as the holder (optional
accessory) and base of the special auxiliary
equipment.
Capacity: wooden material (W × H × L)
300 mm × 45 mm × 1300 mm, or
180 mm × 25 mm × 2000 mm
22. Installing the holders ... (Optional accessory)
The holders help keep longer workpieces stable and
in place during the cutting operation.
(1) As indicated in Fig. 27, use a steel square for aligning
the upper edge of the holders with the base surface.
Loosen the 6 mm wing nut. Turn a height adjustment
bolt 6 mm, and adjust the height of the holder.
(2) After adjustment, firmly tighten the 6 mm wing nut
and fasten the holder with the 6 mm knob bolt
(optional accessory). If the length of Height
Adjustment Bolt 6 mm is insufficient, spread a thin
plate beneath. Make sure the end of Height
Adjustment Bolt 6 mm does not protrude from the
holder.
CAUTION
When transporting or carrying the tool, do not grasp
the holder.
There is the danger of the holder slipping out of the
base. Grasp the handle instead of the holder.
23. Stopper for precision cutting ... (Stopper and holder
are optional accessory)
The stopper facilitates continuous precision cutting
in lengths of 285 mm to 450 mm.
