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 (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 200mm (7-7/8") 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.
11
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.
3. Checking the saw blade lower limit position
Check that the saw blade can be lowered 12mm to 13mm (15/32" to 1/2") below the

4. Lower limit position of saw blade when cutting a large workpiece
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 procedures (1) to (4) indicated below.
(Fig. 10-b)
Furthermore, when changing the position of a 8mm
depth adjustment bolt that serves as a lower limit
position stopper of the saw blade, it becomes
necessary to shift the position of a 8mm hexagon
socket set screw that is in the screw hole for the
8mm depth adjustment bolt that serves as the
stopper.
(1) Loosen the 8mm wing nut.
(2) Insert your 6mm hexagon bar wrench from
behind of the tool and turn the 8mm hexagon
socket set screw to the left (counterclockwise)
as viewed from behind of the tool.
(3) Turn the 8mm depth adjustment bolt, change
the height where the bolt head and the gear
case contacts, and adjust the lower limit
position of the saw blade. One turn of the 8mm
depth adjustment bolt changes the lower limit
position of the saw blade by about 8mm (5/
16"), and this information can be used as a
rough guide.
NOTE: When cutting a workpiece exceeding 88mm (3-15/32") in height in right-angle
cutting or 56mm (2-7/32") in left bevel angle cutting or 31mm (1-7/32") in right
bevel angle cutting, adjust the lower limit position so that the base of the
motor head (see Fig. 10-a) will not come in contact with the workpiece.
To adjust the lower limit position of the saw blade, follow the procedures (1) to (3)
shown in Fig. 10-a.
(1) Loosen the 8mm wing nut so that the 8mm depth adjustment bolt can be turned by
hand.
12
(2) Lower the motor head, and thrun the 8mm depth adjustment bolt by hand and
make adjustments so that there can be a clearance of 2mm to 3mm (3/32" to 1/8")
between the lower limit position of the motor head and the top of the workpiece at
the saw blade's lower limit position (where the head of the 8mm depth adjustment
bolt contacts the gear case.
(3) After adjustment, turn the 8mm wing nut until it contacts the Hinge (see Fig. 10-b),
and fully tighten it.

otherwise, the position of a laser line can go out of order, resulting in
the damage of the laser marker as well as a shortened service life.
* Keep the laser marker lit only during a cutting operation. Prolonged
lighting of the laser marker can result in a shortened service life.
* Use of controls or adjustments or performance of procedures other
than those specified herein may result in hazardous radiation exposure.
NOTE: * Perform cutting by overlapping the ink line with the laser line.
* When the ink line and the laser line are overlapped, the strength and
weakness of light will change, resulting in a stable cutting operation because
you can easily discern the conformity of lines. This ensures the minimum
cutting errors.
* In outdoor or near-the-window operations, it may become difficult to observe
the laser line due to the sunlight. Under such circumstances, move to a place
that is not directly under the sunlight and engage in the operation.
* Do not tug on the cord behind the motor head or hook your finger, wood
and the like around it; otherwise, the cord may come off and the laser marker
16
may not be lit up.

Depending upon your cutting choice, the laser line
can be aligned with the left side of the cutting width
(saw blade) or the ink line on the right side.
The laser line is adjusted to the width of the saw
blade at the time of factory shipment. Adjust the
positions of the saw blade and the laser line taking
the following steps to suit the use of your choice.
(1) Light up the laser marker and make a groove
of about 5mm (3/16") deep on the workpiece
that is about 20mm (25/32") in height and
150mm (5-29/32") in width. Hold the grooved
workpiece by vise as it is and do not move it.
For grooving work, refer to "11.Groove cutting
procedures" on page 27.

(2) Then, turn the adjuster and shift the laser line.
(If you turn the adjuster clockwise, the laser
line will shift to the right and if you turn it
counterclockwise, the laser line will shift to the
left.) When you work with the ink line aligned
with the left side of the saw blade, align the
laser line with the left end of the groove. (Fig.
22) When you align it with the right side of the
saw blade, align the laser line with the right
side of the groove.
(3) After adjusting the position of the laser line,
draw a right-angle ink line on the workpiece
and align the ink line with the laser line. When
aligning the ink line, slide the workpiece little
by little and secure it by vise at a position where
the laser line overlaps with the ink line. Work
on the grooving again and check the position
of the laser line. If you wish to change the laser
line's position, make adjustments again
following the steps from (1) to (3).
17
NOTE: Check and make sure on a periodic basis if the position of the laser line is in
order. As regards the checking method, draw a right-angle ink line on the
workpiece with the height of about 20mm (25/32") and the width of 150mm
(5-29/32"), and check that the laser line is in line with the ink line [The deviation
between the ink line and the laser line should be less than the ink line width
(0.5mm)]. (Fig. 23)
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.
24).

1. Switch operation
Switch operation the tool is turned on when the switch trigger is pulled and off when
the trigger switch is released.
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 6mm knob bolt. As shown in Fig. 25, the vise
shaft has three locking grooves into which the tip
of the 6mm wing bolt is designed to fit in order to
lock the screw holder in the desired position.
To ensure that the tip of the 6mm wing bolt is
properly aligned with the desired locking groove
on the vise shaft, simply align the upper surface of
the fence to either of three v-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 6mm wing bolt; then turn the upper knob,
as necessary, to securely attach the workpiece in position.
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 56mm (2-7/32") can be fixed with a vise assembly
mounted on the left side. In case the workpiece height exceeds 56mm
(2-7/32"), mount the vise assembly on the opposite side of the inclination
of the motor head. For other compound cutting (left bevel + right miter,
right bevel + left miter and right bevel + right miter), mount the vise
assembly 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. 26 the width of the saw blade
is the width of the cut. Therefore, slide the
workpiece to the right (viewed from the
operator’s position) when length b is desired,
or to the left when length a is desired.
(2) After turning on the switch and checking that
the saw blade is rotating at maximum speed,
slowly push down the handle while holding
down the lever (A) and bring the saw blade in
the vicinity of the material to be cut.
(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 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.
19
* Every time one cutting or deep-cutting operation is finished, turn
the switch off, and check that the saw blade has stopped. Then raise
the handle, and return it to the full retract position.
* Be absolutely sure to remove the cut material from the top of the
turntable, and then proceed to the next step.
* 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.

of workpieces of up to 88mm (3-15/32") square.
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 6mm
flat head screws and the 6mm nuts using the 7mm
holes on the fence surface (two holes on each side).

Loosen the slide securing knob (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. 29. This facilitates cutting of
workpieces of up to 88mm (3-15/32") in height
and 312mm (12-9/32") in width.
Workpieces up to 91mm (3-19/32") high and
(2)
300mm (11-13/16") wide:
Workpieces of up to 91mm (3-19/32") in height
and up to 300mm (11-13/16") in width can be
cut in the same manner as described in
paragraph 6-(1) above.
CAUTION:* When cutting a workpiece of 88mm (3-15/32") 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 3mm (3/32" to
1/8") 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. 29.
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.

dimensions for bevel cutting, refer to “SPECIFICATIONS” table on page 6.
(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.
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. 30, 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.
21
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 61mm(2-13/32") height in the left 45° bevel
cutting position or a workpiece of 36mm (1-13/32") 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 3mm (3/32" to 1/8") at the lower limit position
(refer to “3. Checking the saw blade lower limit position” on page 12).
8. Miter cutting procedures
(1) Loosen the side handle and pull up the lever
for angle stoppers. Then, adjust the turntable
until the indicator aligns with desired setting
on the miter scale (Fig. 31).
(2) Re-tighten the side handle to secure the
turntable in the desired position.
(3) The miter scale (Fig. 32) 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. 33).
(5) Therefore, to cut a workpiece at a grade of 2/
10, set the indicator to position a as indicated
in Fig. 32.

Check that the miter scale and the tip of
the indicator are properly aligned.
* Operation of the saw with the miter
scale and indicator out of alignment, or
with the side handle not properly
tightened, will result in poor cutting
precision.
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 6.
22
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 subfence counterclockwise, and engage in the cutting operation.
10. Crown molding cutting procedures

properly aligned with the desired locking
groove on the vise shaft, simply align the upper
surface of the fence to either of three v-grooves
on the vise shaft surface or to the lower surface
of the screw holder.
WARNING: Always firmly clamp or vise to secure the crown molding to the fence;
otherwise the crown molding might be thrust from the table and cause
bodily harm.
Do not bevel cutting. The main body or saw blade may contact the sub
fence, resulting in an injury.
26
CAUTION: Always confirm that the motor head (see Fig. 1) does not contact the
crown molding vise ass’y when it is lowered for cutting. If there is any
danger that it may do so, loosen the 6mm knob bolt and move the crown
molding vise ass’y to a position where it will not contact the saw blade.
Position crown molding with its WALL CONTACT EDGE against the guide fence and its
CEILING CONTACT EDGE against the crown molding Stoppers as shown in Fig. 45-b.

12. 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. 48-a. Set the wood plate near the cutting section.
When cutting aluminum materials, coat the saw blade with cutting oil (non-combustible)
to achieve smooth cutting and a fine finish.
In addition, in case of a U-shaped workpiece, use the wood plate as shown in Fig. 48-b
to ensure stability in the lateral direction, and clamp it near the cutting section of the
workpiece and tighten it using both the vise assembly and the clamp available in the
market.

SAW BLADE MOUNTING AND DISMOUNTING
WARNING: * To prevent an accident or personal injury, always turn off the trigger
switch and disconnect the power plug from the receptacle before
removing or installing a saw blade.
If cutting work is done in a state where the bolt is not sufficiently
tightened, the bolt can get loose, the blade can come off, and the lower
guard can get damaged, resulting in injuries.
Also, check that the bolts are properly tightened before plugging the
power plug into the receptacle.
* If the bolts are attached or detached using tools other than the 10mm
box wrench (standard accessory), excessive or improperly tightening
occurs, resulting in injury.
1. Mounting the saw blade (Fig. 50-a, Fig. 50-b and Fig. 50-c)
(1) Use the accessory 10mm box wrench to loosen the 6mm bolt fastening the spindle
cover and then remove the spindle cover. (Only model 240V)
(2) Press in spindle lock and loosen bolt with 10mm box wrench (standard accessory).
Since the bolt is left-hand threaded, loosen by turning it to the right as shown in
Fig. 50-c.
NOTE: If the spindle lock cannot be easily pressed in to lock the spindle, turn the bolt
with 10mm box wrench (standard accessory) while applying pressure on the
spindle lock.
The saw blade spindle is locked when the spindle lock is pressed inward.

MAINTENANCE AND INSPECTION
WARNING: To avoid an accident or personal injury, always confirm that the trigger
switch is turned OFF and the power plug has been disconnected from the
receptacle before performing any maintenance or inspection of this tool.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the first sign of deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade can cause
ineffective operation and possible overload to the motor.
CAUTION: Never use a dull saw blade. When a saw blade is dull, its resistance to
the hand pressure applied by the tool handle tends to increase, making it
unsafe to operate the power tool.
