English
○ To lower the saw head to cut, the lock must be released
by pressing the lever (A) with your thumb.
(1) When you push down the handle while pushing the
lever (A), check that the lower guard revolves smoothly
(Fig. 6).
(2) Next, check that the lower guard returns to the original
position when the handle is raised.
10. Oblique angle
Before the power tool is shipped from the factory, it is
adjusted for 0°, right angle, left 45° bevel cutting angle
and right 45° bevel cutting angle with the 8 mm set
screw, 8 mm bolt (A) and 8 mm bolt (B).
When changing the adjustment, change the height of
the 8 mm set screw, 8 mm bolt (A), or 8 mm bolt (B) by
turning them.
When changing the bevel angle to the right 45°, pull the
set pin (A) on the direction shown in Fig. 7-b and incline
the motor head to the right.
When adjusting the motor head to 0°, always return the
set pin (A) to its initial position as shown in Fig. 7-b.
11. Checking the saw blade lower limit position
Check that the saw blade can be lowered 9 mm to
10 mm below the table insert.
When you replace a saw blade with a new one, adjust
the lower limit position so that the saw blade will not cut
the turntable or complete cutting cannot be done.
To adjust the lower limit position of the saw blade, follow
the procedure (1) indicated below. (Fig. 8)
Furthermore, when changing the position of a 8 mm
depth adjustment bolt that serves as a lower limit position
stopper of the saw blade.
(1) Turn the 8 mm depth adjustment bolt, change the height
where the bolt head and the hinge contacts, and adjust
the lower limit position of the saw blade.
NOTE
Confi rm that the saw blade is adjusted so that it will not
cut into the turntable.
PRIOR TO CUTTING
1. Cutting a groove on the guard
Holder (A) has a guard (see Fig. 10) into which a groove
must be cut when using the tool for the fi rst time. Loosen
the 6 mm knob bolt to retract the guard slightly.
After placing a suitable wooden piece to sit on the
fence and the table surfaces, fi x it with the vise. Slide
the motor head backwards to the end. Then tighten the
slide securing knob. After the switch has been turned on
and the saw blade has reached maximum speed, slowly
lower the handle to cut a groove on the guard. (See
Fig. 19)
CAUTION
Do not cut the groove too quickly; otherwise the guard
might become damaged.
Do not use slide cutting for grooving tasks.

PRACTICAL APPLICATIONS

WARNING
○ To avoid personal injury, never remove or place a
workpiece on the table while the tool is being operated.
○ Never place your limbs inside of the line next to warning
sign while the tool is being operated (see Fig. 9). This
may cause hazardous conditions.
CAUTION
○ It is dangerous to remove or install the workpiece while
the saw blade is turning.
○ When sawing, clean off the shavings from the turntable.
○ If the shavings accumulate too much, the saw blade from
the cutting material will be exposed. Never subject your
hand or anything else to go near the exposed blade.
1. Switch operation
Pulling the trigger turns the switch on. Releasing the
trigger turns the switch off .
2. Using the Vise Assembly (Standard accessory)
(Fig. 11)
(1) The vise assembly can be mounted on either the left
fence {Fence (B)} or the right fence {Fence (A)}.
(2) The screw holder can be raised or lowered according to
the height of the workpiece.
(3) Turn the upper knob and securely fi x the workpiece in
position.
WARNING
Always fi rmly clamp or vise to secure the workpiece to
the fence; otherwise the workpiece might be thrust from
the table and cause bodily harm.
CAUTION
Always confi rm that the motor head does not contact the
vise assembly when it is lowered for cutting. If there is
any danger that it may do so, move the vise assembly to
a position where it will not contact the saw blade.
3. Positioning the table insert (Fig. 12)
Table inserts are installed on the turntable. When
shipping the tool from the factory, the table inserts are
so fi xed that the saw blade does not contact them. The
burr of the bottom surface of the workpiece is remarkably
reduced, if the table insert is fi xed so that the gap
between the side surface of the table insert and the saw
blade will be minimum. Before using the tool, eliminate
this gap in accordance with the following procedure.
(1) Right angle cutting
Loosen the three 5 mm machine screws, then secure
the left side table insert and temporarily tighten the 5 mm
machine screws of both ends. Then fi x a workpiece
(about 200 mm wide) with the vise assembly and cut it
off . After aligning the cutting surface with the edge of the
table insert, securely tighten the 5 mm machine screws
of both ends. Remove the workpiece and securely
tighten the 5 mm center machine screw. Adjust the right
hand table insert in the same way.
(2) Left and right bevel angle cutting
Adjust the table insert in the manner same procedure for
right angle cutting.
CAUTION
After adjusting the table insert for right angle cutting, the
table insert will be cut to some extent if it is used for bevel
angle cutting.
When bevel cutting operation is required, adjust the
table insert for bevel angle cutting.
4. Confi rmation for use of sub fence (A) (Fig. 13)
WARNING
When right angle cutting, loosen the 6 mm wing bolt,
then slide the sub fence (A) outward and remove it.
Failure to do so may result in the main body or saw blade
coming into contact with the sub fence (A) and causing
injury.
This power tool is equipped with a sub fence (A).
In the case of direct angle cutting and left bevel angle
cutting, use the sub fence (A). Then, you can realize
stable cutting of the material with a wide back face.
When right angle cutting, loosen the 6 mm wing bolt,
then slide the sub fence (A) outward and remove it, as
shown in Fig. 13.
5. Confi rmation for use of sub fence (B) (Fig. 13)
WARNING
When left angle cutting, loosen the 6 mm wing bolt, then
slide the sub fence (B) outward. Failure to do so may
result in the main body or saw blade coming into contact
with the sub fence (B) and causing injury.
