depth, turn the power tool OFF and let the
saw blade stop completely before raising
the handle from the workpiece to return it
to the full retract position.
CAUTION: *Increased pressure on the handle will not increase the cutting speed.
On the contrary, too much pressure may result in overload of the
motor and/or decreased cutting efficiency.
WARNING: * Confirm that the trigger switch is turned OFF and the power plug
has been removed from the receptacle whenever the tool is not in
use.

CAUTION: *If the handle is pressed down with excessive or lateral force, the
saw blade may vibrate during the cutting operation and cause
unwanted cutting marks on the workpiece, thus reducing the
quality of the cut.
Accordingly, press the handle down gently and carefully.
*In slide cutting, gently push the handle back (rearwards) in a single,
smooth operation.
Stopping the handle movement during the cut will cause unwanted
cutting marks on the workpiece.
WARNING: * For slide cutting, follow the procedures indicated above in Fig. 21.
Forward slide cutting (toward the operator) is very dangerous
because the saw blade could kick upward from the workpiece.
Therefore, always slide the handle away from the operator.
*Always return the carriage to the full rear position after each
crosscut operation in order to reduce the risk of injury.
*Never put your hand on the side handle during the cutting operation
because the saw blade comes close to the side handle when the
motor head is lowered.
and 305mm (12") wide:
Loosen the slide securing knob, grip the
handle and slide the saw blade forward.
Then press down on the handle and slide
the saw blade back to cut the workpiece
as indicated in Fig. 21. This facilitates
cutting of workpieces of up to 65mm (2-9/
16") in height and 305mm (12") in width.
and 280mm (11") wide:
Workpieces of up to 75mm (2-15/16") in
height and up to 280mm (11") in width can
be cut in the same manner as described
in paragraph 5-(1) above.

Fig. 22
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 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 safety cover
to be caught in the cutting groove of the workpiece and to contact
the saw blade.
Scale
Clamp lever
(1) Loosen the clamp lever and bevel the saw
blade to the left.
(2) Adjust the bevel angle to the desired
setting while watching the scale and
indicator, then secure the clamp lever.
(3) Follow the procedures indicated in
paragraphs 4 and 5 above. For maximum
dimensions for bevel cutting of up to
39mm (1-9/16") in height and 305mm (12")
width.
7. Miter cutting procedures

desired setting on the miter scale (Fig. 25).
a
(2) Re-tighten the side handle to secure the
turntable in the desired position.
(3) The miter scale (Fig. 23) indicates both the
cutting angle on the angle scale and the
gradient on the grade scale.
(4) The gradient, which is the ratio of the
height to the base of the triangular section
to be removed, may be used for setting
the miter scale instead of the cutting
angle, if desired (see Fig. 24).
(5) Therefore, to cut a workpiece at a grade
of 2/10, set the indicator to position a as
indicated in Fig. 23.

8. Compound cutting
Compound cutting can be performed by following the instructions in 6 and 7 above.
At a bevel angle of 45° and a miter angle of 45°, a workpiece of 39mm (1-9/16") in height
and up to 220mm (8-21/32") in width can be cut.
CAUTION: Always secure the workpiece with the right hand side for compound
cutting. Never rotate the turntable to the right for compound cutting,
because the saw blade might then contact the clamp or vise that
secures the workpiece, and cause personal injury or damage.
9. Groove cutting procedures

Grooves in the workpiece can be cut as indicated in Fig. 46 by adjusting the 8mm depth
adjustment bolt.
Cutting depth adjustment procedure:
(1) Loosen the 8mm wing nut and turn the 8mm depth adjustment bolt by hand.
(2) Adjust to the desired cutting depth by setting the distance between the saw blade
and the surface of the base (see b in Fig. 26).
(3) The 8mm wing nut must be properly tightened after the adjustment has been
completed.
22
Page 23
NOTE: When cutting a single groove at either end of the workpiece, remove the
unneeded portion with a chisel.
10. Cutting easily-deformed materials, such as aluminum sash
Materials such as aluminum sash can easily deform when tightened too much in a vise
assembly. This will cause inefficient cutting and possible overload of the motor.
When cutting such materials, use a wood plate to protect the workpiece as shown in
Fig. 28.
When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible)
to achieve smooth cutting and a fine finish.
