2. Positioning the table insert
[Right angle cutting] [Left bevel angle cutting] [Right bevel angle cutting]
Fig. 9-a Fig. 9-b Fig. 9-c
Table inserts are installed on the turntable. When shipping the tool from the factory, the table inserts
are so fixed 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 fixed 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 6mm machine screws, then secure the left side table insert and temporarily tighten
the 6mm machine screws of both ends. Then fix a workpiece (about 7-7/8" (200mm) wide) with the
vise assembly and cut it off. After aligning the cutting surface with the edge of the table insert,
securely tighten the 6mm machine screws of both ends. Remove the workpiece and securely tighten
the 6mm 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 shown in Fig. 9-b and Fig. 9-c following the 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 cut-
ting.

3. Checking the saw blade lower limit position
Check that the saw blade can be lowered 11/32" to 13/32" (9mm to 10mm) below the table insert as
shown in Fig. 10-a.
If necessary, adjust as follows:
(1) Loosen the 8mm wing nut and the two 8mm nuts on the 8mm depth adjustment bolt.
(2) Turn the 8mm depth adjustment bolt as necessary to set the lower limit position.
(3) Once the adjustment is complete, fully tighten the two 8mm nuts and the 8mm wing nut.
NOTE: Before tightening the two 8mm nuts and the 8mm wing nut, confirm that the saw blade is
adjusted so that it will not cut into the turntable.
Fig. 10-a Fig. 10-b
4. 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 8mm bolt (A), 8mm bolt (C) and the 8mm bolt (B).
When changing the adjustment, change the height of the 8mm bolt (A), 8mm bolt (C) or the 8mm bolt
(B) by turning them.
When changing the bevel angle to the right 45°, pull the fixing pin on the direction shown in Fig. 11 and
incline the motor head to the right.
When adjusting the motor head to 0°, always return the fixing pin to its initial position.
Fig. 11-a Fig. 11-b
5. Securing the workpiece
WARNING: Always clamp or vise to secure the workpiece to the fence; otherwise the workpiece
might be thrust from the table and cause bodily harm.
6. Installing the holders ... (Optional accessory)
The holders help keep longer workpieces stable and in place dur-
ing the cutting operation.
(1) As indicated in Fig. 12, use a steel square for aligning the upper
edge of the holders with the base surface.
(2) After aligning, secure the holders with the 6mm knob bolts (Op-
tional accessory).

8. Using an ink line
(1) Right angle cutting
Loosen the 8mm knob bolt and contact the tip of the guard
with the workpiece.
Aligning the ink line on the workpiece with the groove of the
guard, the workpiece is cut on the ink line (Fig. 14).
Fig. 14
(2) Miter cutting and compound cutting
(Miter cutting + bevel cutting)
Upon lowering the motor section, the safety cover is raised and
the saw blade appears.
Align the ink line with the saw blade (Fig. 15).
CAUTION: In some arrangements when the turntable is
rotated, the guard projects from the fence sur-
face. Loosen the 8mm knob bolt and push the
guard to the retracted position. Never lift the
safety cover while the saw blade is rotating.

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. This may cause hazardous conditions (see Fig. 16).

1. Switch operation
The trigger switch lock-off button is designed to prevent inadvert-
ent operation of the power tool. To operate the power tool, it is nec-
essary to first fully insert the lock-off button into the hole on the
handle as shown in Fig. 17.
The trigger switch will not operate unless the lock-off button has
been pushed in.
When the trigger switch is released, the power goes off and the
lock-off button automatically returns to its initial position, locking
the trigger switch.
Fig. 17
WARNING: Always remove the lock-off button from the handle when the power tool is not in
use. This will ensure that the power tool cannot be turned on accidentally or by
someone (especially a child) who is not qualified to use the power tool. If the lock-off
button is left in the handle, serious personal injury can result. Since the lock-off button
fits rather tightly, it may be necessary to turn it to the left and right during mounting
and removing.
2. Using the Vise Assembly (Standard accessory)
The vise assembly can be mounted on either the left fence (Fence
(B)) or the right fence (Fence (A)), and can be raised or lowered
according to the height of the workpiece.
To raise or lower the vise assembly, first loosen the 8mm knob
bolt. As shown in Fig. 18, the vise shaft has three locking grooves
into which the tip of the 8mm knob bolt is designed to fit in order
to lock the screw holder in the desired position.
To ensure that the tip of the 8mm knob bolt is properly aligned
with the desired locking groove on the vise shaft, simply align the
upper surface of the fence to either of two grooves on the vise
shaft surface or to the lower surface of the screw holder.
Therefore, the vise assembly can be attached in either of three
positions to ensure proper height adjustment.
After adjusting the height, firmly tighten the 8mm knob bolt; then
turn the upper knob, as necessary, to securely attach the workpiece
in position.
Fig. 18
CAUTION: Always confirm that the motor head (see Fig. 1) does not contact the vise assembly
when it is lowered for cutting. If there is any danger that it may do so, loosen the
8mm knob bolt slightly and move the vise assembly to a position where it will not
contact the saw blade.
In case of compound cutting of left bevel angle and left miter angle, a workpiece of
up to 45mm can be fixed with a vise assembly mounted on the left side. In case the
workpiece height exceeds 45mm, mount the ivse assembly on the opposite side of
the inclination of the motor head. For other compound cutting (left bvel + right miter,
right bevel + left miter and right bevel + right miter), mount the vise asembly on the
opposite side of the inclination of the motor head to avoid the contact of the vise
assembly with the motor head.

3. Cutting Operation
(1) As shown in Fig. 19 the width of the saw blade is the
width of the cut. Therefore, slide the workpiece to the
right (viewed from the operators position) when length
b is desired, or to the left when length a is desired.
(2) Once the saw blade reaches maximum speed, push
the handle down carefully until the saw blade
approaches the workpiece.
(3) Once the saw blade contacts the workpiece, push the
handle down gradually to cut into the workpiece.
(4) After cutting the workpiece to the desired 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.
* Always remove the lock-off button from the handle and store it in a secure place
after completing the work.
4. Cutting narrow workpieces (Press cutting)
Slide the hinge down to holder (A), then tighten the slide securing
knob as indicated in Fig. 20.
Lower the handle to cut the workpiece.
Using the power tool this way will permit cutting of workpieces of
up to 2-15/16" (75mm) square.
NOTE: When cutting a workpiece of over 2-15/16" (75mm)
square, adjust the gap between the holder (A) and the
hinge to 25/32" (20mm).
Using the power tool this way will permit cutting of
workpieces of up to 3-15/16" (100mm).
Fig. 20
5. Cutting wide workpieces (Slide cutting)
(1) Workpieces up to 4-7/32" (107mm) high and 12" (305mm) 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 4-7/32" (107mm) in height and 12"
(305mm) in width.
(2) Workpieces up to 4-23/32" (120mm) high and 10-7/32" (260mm)
wide: Workpieces of up to 4-23/32" (120mm) in height and up
to 10-7/32" (260mm) in width can be cut in the same manner as
described in paragraph 5-(1) above.
Fig. 21
CAUTION: * When cutting a workpiece of 4-23/32" (120mm) 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 5/64" to 1/8" (2 to 3mm) 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 opera-
tion.
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.
6. 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 6mm flat head screws and the 6mm nuts
using the 7mm holes on the fence surface (two holes on each side).
(Fig. 22)
Refer to page 9 "SPECIFICATIONS" for the thickness of the auxiliry
board.
Fig. 22
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 fixing pin
towards the rear.
(2) Adjust the bevel angle to the desired setting while watching
the bevel angle scale and indicator, then secure the clamp le-
ver.
(3) Follow the procedures indicated in paragraphs 4 and 5 above.
For maximum dimensions for bevel cutting, refer to
SPECIFICATIONS table on page 9.
Fig. 23
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 danger-
ously.
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.
CAUTION: When cutting a workpiece of 2-15/16" (75mm) height in the left 45° bevel cutting
position or a workpiece of 1-3/4" (45mm) 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 5/64" to 1/8" (2 to 3mm) at the
lower limit position (refer to 3. Checking the saw blade lower limit position on
page 14).

8. Miter cutting procedures
(1) Loosen the side handle and adjust the turntable until the indi-
cator aligns with the desired setting on the miter scale (Fig. 26).
(2) Re-tighten the side handle to secure the turntable in the de-
sired position.
(3) The miter scale (Fig. 24) 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. 25).
(5) Therefore, to cut a workpiece at a grade of 2/10, set the indicator
to position a as indicated in Fig. 24.
NOTE: * Positive stops are provided at the right and left of
the 0° center setting, at 15°, 22.5°, 31.6°, 35.3° and
45° settings.
Check that the miter scale and the tip of the indica-
tor are properly aligned.
* Operation of the saw with the miter scale and indi-
cator out of alignment, or with the side handle not
properly tightened, will result in poor cutting preci-
sion.
Fig. 26
9. Compound cutting procedures
Compound cutting can be performed by following the instructions in 7 and 8 above. For maximum
dimensions for compound cutting, refer to SPECIFICATIONS table on page 9.
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 be-
cause the saw blade may come into contact with the hand that is securing the
workpiece.
10. Crown molding cutting procedures
Fig. 27 shows two common crown molding types having angles of (θ) 38° and 45°.
For the typical crown molding fittings, see Fig. 28.
