* Continued cutting operation can result in overload of
the motor. Touch the motor and if it's hot, stop your
cutting operation once and rest for 10 minutes or so,
and then restart your cutting operation.
* Do not operate the head section or lift up the main
unit while grasping the digital display (Fig. 1) as this
could cause damage to the digital display.
4. Cutting narrow workpieces (Press cutting)
Slide the hinge down to holder (A), then tighten the
slide securing knob (A)/(B) (see Fig. 2) as indicated in
Fig. 30.
Lower the handle to cut the workpiece.
Using the power tool this way will permit cutting of
workpieces of up to 107 mm square.
Fig. 30
5. Cutting large workpieces
There may be case when a complete cutting cannot
be done depending on the height of workpiece. In this
case, mount an auxiliary board with the 6 mm flat
head screws and the 6 mm nuts using the 7 mm holes
on the fence surface (two holes on each side). (Fig.
31)
Refer to page 5 “SPECIFICATIONS” for the thickness
of the auxiliry board.

6. Cutting wide workpieces (Slide cutting)
(1) Workpieces up to 107 mm high and 312 mm wide:
Loosen the slide securing knob (A) (see Fig. 2), 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.
32. This facilitates cutting of workpieces of up to 107
mm in height and 312 mm in width.
(2) Workpieces up to 120 mm high and 260 mm wide:
Workpieces of up to 120 mm in height and up to 260
mm in width can be cut in the same manner as
described in paragraph 6-(1) above.

CAUTION
* When cutting a workpiece of 120 mm height, 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.
* 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. 32.
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.
7. Bevel cutting procedures
(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. 33, 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.
(3) Follow the procedures indicated in paragraphs 4,5 and
6 above. For maximum dimensions for bevel cutting,
refer to “SPECIFICATIONS” table on page 5.
