The new slide compound miter saws Models C 8FSE and C 8FSHE are developed to bring to the European
market at the prices as low as the competitors’ products. The Model C 8FSHE is equipped with a laser marker
for easier alignment with the ink line and an LED light to illuminate the working surface brightly. In addition, the
Model C 8FSE that is mostly the same as the Model C 8FSHE except that it is not equipped with the laser
marker and the LED light is introduced in tandem with the Model C 8FSHE. With the new Models C 8FSE and

Laser marker (Only the Model C 8FSHE)
Use the laser marker for aligning with the ink line on the
workpiece.
(1) Cutting position can be properly adjusted by aligning the
positioning ink line with the laser line. There is no need to
make a long ink line on the workpiece.
(2) There is no need to lower the motor head to align with the
ink line because the laser marker makes a laser line on the
workpiece. In addition, cutting position can be easily
adjusted because the operator can hold the workpiece with
both hands to move.
(3) Cutting position can be easily adjusted because the laser
line can be aligned with an optionally angled ink line.
(4) Even the workpieces such as crown moldings and base
boards that have decorative surfaces and are difficult to be
made an ink line can be cut just by aligning the laser line
with the ink line on the fence side. The laser line is
adjusted to the width of the saw blade at the time of factory
shipment. Depending upon the user's 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. Adjust
the position of the laser line according to "Position
adjustment of laser line" on page 17.

LED light (Only the Model C 8FSHE)
The Model C 8FSHE is equipped with an LED light to light up
over a table brightly. The two LEDs incorporated in it light up the
materials and the point of the saw blade brightly. The LED light
can freely move at the time of right and left bevel cutting
because the support is flexible. Therefore, it lights up the
materials and the point of the saw blade brightly at any time.
Fig. 2
Lightweight
The Model C 8FSE is most lightweight (14 kg) in the class of 8” (216 mm) slide compound miter saws
because the reinforcement rib of the table is placed in the most suitable position.

Positive angle stoppers
The Models C 8FSE and C 8FSHE have positive angle
stoppers in the turn table at the right and the left of the 0°
center setting, at 15°, 22.5°, 31.6° and 45° settings.
Thanks to the positive angle stoppers, positioning can be
done more securely than the ball index method utilized in
the current Model C 8FB2. In addition, a lever is provided
at the lower tip of the turn table to secure or release the
positive angle stoppers.
Adjustment of the turn table and positioning can be easily
done while holding the side handle.
Bevel cutting range: Left 48° to right 5°
Possible range of bevel cutting is from left 48 degrees to right 5
degrees. By the simple operation of the set pin, you can set the
position of the right angle and left 45 degrees.
In addition, setting to approximately 30 degrees and 33.9
degrees for crown molding cutting can be done by this set pin.

High dust collecting performance
The dust collecting performance of the Models C 8FSE and C 8FSHE are remarkably higher than the other
models thanks to the adoption of new dust guide and gear case.

workpiece of 75 mm (2-15/16") in height as indicated in [ ] in Table 2,
adjust the saw so that there is a clearance of 2 to 3 mm (3/32" to 1/8")
between the bottom surface of the head and the top surface of the
workpiece at the lower limit position of the saw blade as shown in Fig. 6-b. (See the Instruction Manual
"Lower limit position of saw blade when cutting a large workpiece.")
Please note that, when cutting in this position, it is necessary to use an auxiliary board of 30 mm (1-3/16")
wide so that the workpiece on the fence side can be cut fully in width.

By turning the turn table to the left or right and inclining the saw blade section (head) to the left or right, the
Models C 8FSE and C 8FSHE are capable of compound cutting (bevel and miter, see Figs. 10-a and 10-b)
of workpieces with the maximum dimensions shown in Table 6.
Fig. 10-bFig. 10-a
Splinter guard, also serving for cut alignment
When cutting the ends of a workpiece, splinters may drop on the saw blade and be cut into pieces. The
Models C 8FSE and C 8FSHE are equipped with a splinter guard to prevent such splinter cutting.
(Refer to "SELLING POINTS .") Safe cutting is also ensured in bevel cutting because the splinter guard
is tilted with the saw blade.
Groove cutting
The Models C 8FSE and C 8FSHE can cut grooves at desired depth by adjusting the 6-mm depth adjustment bolt
manually. (Refer to "Groove cutting procedures" described in the Instruction Manual for details.)
NOTE: The Models C 8FSE and C 8FSHE cannot cut grooves at const ant depth unless the sa w blade
slides in parallel with the base surface.

PRECAUTIONS IN SALES PROMOTION
1. Safety instructions
In the interest of promoting the safest and most efficient use of the Models C 8FSE and C 8FSHE Slide
Compound Miter Saws by all of our customers, it is very important that at the time of sale the salesperson
carefully ensures that the buyer seriously recognizes the importance of the contents of the Instruction
Manual, and fully understands the meaning of the precautions listed on the Warning Labels, Warning Signs
and Caution Labels attached to each machine.
A. Instruction manual
Although every effort is made in each step of design, manufacture and inspection to provide protection
against safety hazards, the dangers inherent in the use of any slide compound miter saw cannot be
completely eliminated. Accordingly, general precautions and suggestions for the use of electric power tools,
and specific precautions and suggestions for the use of the slide compound miter saw are listed in the
Instruction Manual to enhance the safe, efficient use of the tool by the customer. Salespersons must be
thoroughly familiar with the contents of the Instruction Manual to be able to offer appropriate guidance to
the customer during sales promotion.
B. Warning labels and caution labels

[AUS/NZL] AS/NZS 2211.1: 2001
[Europe] EN 60825-1: 2001-11
D. Laser marker (only the Model C 8FSHE)
The Model C 8FSHE is equipped with the laser marker that complies with the Class II requirements of the
standard specified in "Relative standards." The Class II laser is defined as follows:
·
The laser power is low and it is safe by the protective measures such as blinking.
However, it is dangerous if the operator’s eyes are exposed directly to the laser for a protracted period.
·
The operator can use the laser equipment without particular training and instruction.
·
The amount of light exposure (output) is 1 mW or less at the position where the operator can be exposed
to the laser radiation during operation. (This is in the case of the U.S.A. The measuring methods and the
output values are different depending on the standards.)
The saw blade unit prevents access of the operator’s eye to the laser-emitting aperture less than 65 mm.
In addition, the amount of light exposure (output) is 1 mW or less (about 0.4 mW) at this position. Thus
the Model C 8FSHE satisfies the Class II requirements adequately. There is no ill effect on the operator’s
body if looking at the laser line on the workpiece during operation.
-14-
CAUTION: (1) Be sure to disconnect the power cord plug from the receptacle before removing the
laser marker for repair. If it is unavoidable to check the operation of the removed
laser marker with the power turned on, face the laser emitting aperture to the ground
to show the laser line on the ground.
(2) Laser radiation when open. DO NOT STARE INTO BEAM OR VIEW DIRECTL Y WITH
OPTICAL INSTRUMENTS.
The life span of the laser marker in the Model C 8FSHE is about 3,600 hours. (About 3 years: 5 hours of
use/day x 240 days/year)
2. Precautions requiring particular attention during sales promotion
A. Ambient illuminance and visibility of laser line (only the Model C 8FSHE)
The visibility of the laser line on the workpiece changes depending on the brightness of the working
environment. Instruct the customer to consider the brightness of the working environment when using the
laser marker referring to the following table.
Table 7 Ambient illuminance and visibility of laser line
Illuminance (lux)3000 or more3000 or more3000 - 2500800 - 600300 - 200150 - 8030 or less
(The working environment where the illuminance is 200 luxes or less is dark and difficult to operate the
Model C 8FSHE.)
The laser line is invisible under direct sunlight of fine weather. Prepare a shaded area or relocate to a
shaded area to operate the Model C 8FSHE.
When a laser line is dazzling, please light up the laser line with a LED light. You can watch a laser line if you
do so.
B. Precautions concerning brake
The Models C 8FSE and C 8FSHE are equipped with a "brake" that stops running when the switch is
turned off. Normally the operation is stopped in 5 - 6 seconds when the switch is turned off. If it takes 10
seconds or more to stop, absolutely avoid further use of this machine. In this event, ensure that your
customers bring this machine in their local Hitachi power tools dealer or Hitachi power tools center for
servicing.
(1) Be sure to use the carbon brushes dedicated to the Models C 8FSE and C 8FSHE (110 V to 120 V:
Code No. 999021, 220 V to 240 V: Code No. 999001). Use of other carbon brushes will adversely affect
the brake performance.
(2) If the brake should fail to work, check the carbon brushes. Replace the carbon brushes with new ones if
their length is shorter than 6 mm. If the brake still does not work, replace the armature ass’y.
-15-
ADJUSTMENT AND OPERATIONAL PRECAUTIONS
1. Confirmation of saw blade lower limit position
The lower limit of the saw blade cutting depth is factory-adjusted so that when the saw blade is fully
lowered, its cutting edge is 10 to 11 mm (13/32" to 7/16") below the upper surface of the turn table in order
to cut workpieces completely without cutting the bottom of the turn table groove. Lower the saw blade and
check that it stops at the correct position (Fig. 16-a).
When changing the position of the 8 mm depth adjustment bolt that serves as the lower limit position
stopper of the saw blade, perform the following steps.
(1) Make the tip of the 8 mm depth adjustment bolt contact with the hinge.
(2) Turn the 8 mm depth adjustment bolt with a 13-mm wrench to adjust the lower limit position of the saw
blade (Fig. 16-c).
CAUTION: Perform the adjustment carefully to ensure that the saw blade does not cut into the turn
table.

2. Confirmation for use of sub fence (Optional accessory)
The sub fence is optionally available (located at the front right of the
base). Use the sub fence for miter cutting and right bevel cutting. The
sub fence supports the workpiece widely for stable cutting. In the
case of left bevel cutting, raise the sub fence as illustrated in Fig. 17
and turn it counterclockwise.
*For the U.S.A. and Canada, the Models C 8FSHE and C8FSE are
equipped with the sub fence as a standard accessory.
Fig. 17
Sub fence
NOTE: Mount the sub fence as follows.
Insert the flat-head sc re w M6 into f ence (B) and mo unt t he sub fe nce a nd the plate. Then t ig hten
the nylon nut M6 with the attach ed 10-mm box wrench so th at the sub fence c an turn smoothly.
WARNING: In the case of left bevel cutting, turn the sub fence counterclockwise. Otherwise the
main body or the saw blade may contact the sub fence resulting in an injury. Be sure to
instruct the customers to tu rn the s ub fence c ountercl ock wise in the case of l ef t bev el
cutting.
-16-
3. Position adjustment of laser line (Only the Model C 8FSHE)
The laser line is adjusted to the width of the saw blade at the
time of factory shipment. Depending upon the cutting choice,
align the laser line with the left side of the cutting width (saw
blade) or the right side according to the following procedure.
First, make a right-angle ink line on the workpiece that is about
20 mm (25/32") in height and 150 mm (5-29/32") in width.
To cut the right side of the ink line with the saw blade as shown
in Fig. 18, align the left side of the saw blade with the ink line
on the workpiece and make a groove of about 5 mm deep on
the workpiece to the middle. Hold the grooved workpiece by
the vise as it is and do not move it. (For grooving work, refer to
the Instruction Manual "Groove cutting procedures.")
Light up the laser marker. Turn the adjuster to align the laser
line with the ink line. (Turning the adjuster clockwise will shift
the laser line position to the right and turning counterclockwise
will shift to the left.) (Fig. 19)
Thus the cutting position matches the laser line position. Align
the ink line on the workpiece 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
(Fig. 20). Work on the grooving again and check the position
of 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.

WARNING:
• Make sure before plugging the power plug into the receptacle tha t the main body and the laser
marker are turned off.
• Exercise utmost caution in handling a switch trigger for the position adjustment of the laser line,
as the power plug is plugged into the receptacle during operation. If the switch trigger is pulled
inadvertently, the saw blade can rotate and result in unexpected accidents.
• Do not remove the laser marker to be used for other purposes.
CAUTION:
• Laser radiation - Do not stare into beam.
• Laser radiation on work table - Do not stare into beam.
If your eye is exposed directly to the laser beam, it can be hurt.
• Do not dismantle it.
• Do not give strong impact to the laser marker (main body of tool); otherwise, the position of a
laser line c a n go out of o r d e r, res u l t i n g i n t h e d a m a g e o f t h e l a s e r m a r k e r a s we l l as a short e n e d
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.
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 operati on
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 obs erve 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 may not be lit up.
Instruct the above precautions on the laser marker to the customers.
-17-
4. How to use the vise assembly
(1) The vise assembly can be mounted on either the left fence
(fence (B)) or the right fence (fence (A)) by loosening 6 mm
wing bolt (A).
(2) The screw holder can be raised or lowered according to the
height of the workpiece by loosening 6 mm wing bolt (B).
After the adjustment, firmly tighten 6 mm wing bolt (B) and fix
the screw holder.
(3) Turn the upper knob and securely fix the workpiece in position
(Fig. 21).
WARNING: Always firmly 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 confirm that the motor head does no t contact the vise assembly when it is
lowered for cutting. If there is any danger that it may do so, loosen 6 mm wing bolt (B)
and move the vise assembly to a position where it will not contact the saw blade.
Fig. 21

bolt (B)
6 mm wing bolt (A)
5. Adjustment of table insert position
The table inserts are installed on the turn table. When the machine is shipped from the factory, the table
inserts are positioned so that there is no chance that the saw blade will come in contact with either side of
the saw blade slot even if the machine is used for 45° bevel cutting. Before operating the machine, adjust
the position of the table inserts so that the sides of the saw blade align with the edges of the table inserts
according to the following procedure.
First, loosen the three 6-mm machine screws that fasten the table inserts, and temporarily tighten the two
outside screws (front and back). Next, clamp a workpiece (about 200 mm (7-7/8") wide) with the vise
assembly and cut the workpiece. Align the cutting surfaces with the table inserts as shown in Figs. 22-a and
b, and securely tighten the front and back 6-mm machine screws. Finally, remove the workpiece and
securely tighten the middle 6-mm machine screw.
If adjustment is done as described, workpieces can be cut precisely by aligning the appropriate side edge
of the table inserts with the ink line on the workpiece. Adjust the table inserts as necessary for the type of
cutting desired (right-angle or left bevel cutting).

6. Cutting operation
(1) Cutting efficiency will be reduced if a dull saw blade is used,
if an excessively long extension cord is used, or if the wire
gauge of the extension cord is too small. (For details, refer
to the Instruction Manual "USE PROPER EXTENSION
CORD.") This is particularly important when cutting materials
with dimensions which are at or near the maximum capacity
for the machine.
(2) The customer should be advised to thoroughly inspect the
workpiece to ensure that there are no metallic objects (nails
in particular), sand, or other foreign matter in or on the
workpiece. Contacting such foreign matter will not only
shorten the service life of the saw blade, but could cause
serious accident. Should the saw blade tips be broken off,
the tips may fly toward the operator.
Fig. 23
(3) Press cutting ( 3
in Fig. 23)
The Models C 8FSE/C 8FSHE can be used for press
cutting of workpieces up to 65 mm square in a single
operation by simply pushing the saw blade section
3
downward in the same manner as the Model C 8FB2.
Slide the hinge to the end of holder (A) and tighten the slide
securing knob securely.
CAUTION: (For Europe and Australia)
This slide compound miter saw is equipped with a saw head lock as a safety device.
T o lo wer the saw head to cut, the lock must be released by pressing the lock lever with your thumb.
(4) Slide cutting ( 1
to 5 in Fig. 23)
Slide cutting procedures and precautions are described below.
1 Loosen the slide securing knob.
2 Grip the handle and pull the saw blade section in the arrow direction (toward the operator).
3 Push the handle downward and cut the workpiece (press cutting).
(For Europe and Australia)
Push the handle downward while holding down the lock lever with your thumb and cut the workpiece.
CAUTION: If the handle is pushed down forcibly and excessively fast, it could cause the saw blade
vibration and partial sliding which would leave unwanted cutting marks on the
workpiece. Instruct the customer to slowly and carefully press down the handle.
4 While pressing down on the handle, slide the saw blade section in the arrow direction and cut the
workpiece.
CAUTION: Interrupting the cutting operation partway through the material or sliding the saw blade
section in a jerky manner will produce unwanted cutting marks similar to those
described in
3 above. As a guide, instruct the customer to cut a workpiece of 30 mm
(1-3/16") high and 300 mm (11-7/8") wide in 10 to 15 seconds.
Carefully instruct the customer never, ever to perform slide cutting in the direction toward the operator
(reverse direction of the above). Such operation is extremely hazardous, as the saw blade could ride up
over the workpiece and cause the saw blade section to kick upward unexpectedly, causing possible serious
injury. Instruct the customer to always slide the saw blade section toward the fence while cutting, as shown
by the arrow 4 in Fig. 23.
5 On completion of the cutting operation, turn the switch off and wait for the saw blade to come to a
complete stop before raising the handle to its original position. Raising the handle while the saw blade
is still rotating may cause unwanted cutting marks on the workpiece.
-19-
NOTE:
Techniques to avoid unwanted cutting marks
Uneven and unwanted cutting marks can be avoided by shifting from 3 press cutting to 4 slide
cutting in a single, uninterrupted motion.
Techniques to avoid burnt marks
Burnt marks can be avoided by shifting from 3 press cutting to 4 slide cutting in a single,
uninterrupted motion in the same manner as the above, applying a slight lateral force toward the
cut-off side. Advise the customer that he or she will quickly develop a "feel" and skill for smooth
cutting after performing two or three practice cutting operations.
(5) Miter cutting
Miter cutting is accomplished by turning the turn table. (For details, please refer to the Instruction
Manual "Miter cutting procedures.")
(6) Bevel cutting
Bevel cutting of 0 - 45° to the left or 0 - 5° to the right is accomplished by inclining the motor head
section. (For details, refer to the Instruction Manual "Bevel cutting procedures.")
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 a bout dangerously. When
stopping the bevel cutting operation halfway, start cutting after pulling back the motor
head to the initial position. Starting from half way, 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 50 mm (1-15/16”) height in the le f t 45° bev el cutting position
or a workpiece of 70 mm (2-3/4”) height in the right 5° 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 3 mm (5/64" to 1/8") at the lower limit position
(refer to the Instruction Manual "Checking the saw blade lower limit position").
(7) Compound (miter + bevel) cutting
Compound (miter + bevel) cutting can be accomplished by combining the miter cutting and bevel cutting
operations described in paragraphs (5) and (6) above. (For details, refer to the Instruction Manual
"Compound cutting procedures.") When the saw blade is inclined 45° to the left, the turn table can be
turned up to 45° to the left and right.
(8) Cut surface quality during miter/bevel cutting
The quality of the cut surface depends on the type
Fig. 24
of cutting operation (miter or bevel), the type and
sharpness of the saw blade, whether the workpiece
is cut to the left or right, and various other factors.
In miter and bevel cutting in particular, cutting is
performed across the wood grain, so the condition
of the cut surface depends on whether the wood is
cut with or against the grain. This is the same as
when using electric portable planers. Customers
should be advised of these phenomena so that they
understand that in cases when the cut surface may
not be as smooth as expected or hoped for, it is not
caused by the performance of the saw blade or the
Models C 8FSE/C 8FSHE.
In the cutting examples illustrated in Fig. 24, the cut surfaces on the sides marked ( A ) (cut with the
-20-
grain) are better than those on the sides marked ( B ).
(9) Crown molding cutting
This machine can cut two types of crown molding workpieces by combining the miter and bevel cutting
operations. Figure 25 shows two common crown molding types having angles of (θ) 38° and 45°. For
the typical crown molding fittings, see Fig. 26.
Fig. 26Fig. 25
The table below shows the miter angle and the bevel angle settings that are ideal for the two crown molding
types.
NOTE : For convenience, positive stops are provided for the miter setting (left and right 31.6°)
positions.
For miter cut setting
If the turn table has been set to either of the angles described, move the turn table adjusting side handle
a little to the right and left to stabilize the position and to properly align the miter scale and the tip of the
indicator before the operation starts.
For bevel cut setting
Move handle on miter section to the right and left and check that the position is stable and the angle
scale and the tip of the indicator are properly aligned. Then tighten the clamp lever.

ADJUSTMENT OF COMPONENTS
1. Bevel angle adjustment
Before shipping from the factory, the height of 8-mm bolts (A) and (B) is adjusted so that the saw blade
section (head) will stop at 0° (right angle), and 45° to the left. To change the head stop positions, instruct
the customer to adjust the height of 8-mm bolts (A) and (B) by turning them.
CAUTION:
If there is any clearance between the tip of 8-mm bolt (A) (stopper for 0°) and the fixing pin, the
angle of the saw blade relative to the upper surface of the turn table may not be an exact right angle.
(8-mm bolts (A) and (B) are located at the holder (A).) Press do wn on holder (A) and lock it in
position with the clamp lever so that there is no clearance between the fixing pin and 8-mm bolt (A).

2. Ball bushing (Linear bearing)
(1) Structure of the ball bushing
The ball bushing is commonly called a linear
ball bearing. Inside the bearing is elongated
guide grooves in which steel balls circulate
and roll when a load is applied. (as indicated
by the arrow marks in Fig. 34). This type of
device is widely used in automated machine
tools. The advantage of the ball bushing is
that its friction coefficient remains largely
unchanged even when the load is increased,
ensuring smooth sliding movement.
In addition, slide pipe (B), made of bearing steel and heat treated to a high degree of hardness (HRC 62
to 65), is highly resistant to wear.
Sales persons should have a good understanding of the structure and rugged characteristics of this
exceptional mechanism to enhance sales promotion.
(2) Lubrication
If it is necessary to replace the ball bushing, apply approximately 2 grams (0.1 oz) of grease (Nippeco
SEP 3A) on the steel balls and within the guide grooves of the new ball bushing. If grease is not applied,
it will shorten the service life of the ball bushing, and subsequent abrasive contact between the steel
balls and slide pipe (B) will cause abnormal noise during slide cutting operations. Customers should be
instructed to thoroughly remove sawdust and other foreign matter from slide pipe (A) and slide pipe (B)
and liberally coat them with machine oil at least once a month.

5. Reassembly requiring adjustment
(1) Adjustment of squareness between the saw blade (dummy disc) and the fences
It is necessary to check and adjust the right-angle
orientation between the saw blade (dummy disc)
and the fence after disassembly and replacement of
the Base Ass’y [56], Turn Table [13], Fence (A) [55],
Fence (B) [47], Holder (A) [124] and Hinge (A)
Ass’y [87] and after disassembly, reassembly and
adjustment of the Ball Bushing [114]. Adjust the
squareness (rated value 0.15/100 mm) by moving
the fences along the saw blade (dummy disc).
First, adjust the squareness between the saw blade
and either fence. Then adjust flatness of the two
fences by applying a straight edge to the right and
left fence surfaces. Finally, apply a square to the
fence surface that has not been checked yet and
make sure it forms squareness (rated value
0.15/100 mm) with the saw blade.
Fig. 52
(2) Adjustment of the lower limit position of the saw blade
Adjust the unit so that the saw blade (216 mm (8-1/2")) is 10 to 11 mm (13/32" to 7/16") below the base
surface (or top surface of the table insert). Lower the Gear Case [198] (head) and make Hinge (A) Ass’y[87] contact with the Nylock Bolt M8 x 25 [190] for lower limit position adjustment. Turn the Nylock Bolt
M8 x 25 [190] with a 13-mm wrench and change the height to adjust the lower limit position of the saw

8. Adjustment of laser marker accuracy
(1) Construction of laser marker and functions of each component
The Adjuster [88] located at the side of Hinge (A) Ass’y [87] is a screw used for moving the
Laser Marker [107] horizontally. The laser line can be aligned with the left side of the cutting width
(saw blade) or the ink line on the right side by means of the Adjuster [88]. The accuracy of the
Laser Marker [107] is adjusted by the two Seal Lock Hex. Socket Set Screws M5 x 6 [103].
The Seal Lock Hex. Socket Set Screw M5 x 6 [103] located at the front is mainly used for
adjusting the squareness with the fence surface.
The Seal Lock Hex. Socket Set Screw M5 x 6 [103] located under the Laser Marker [107] is mainly
used for adjusting the squareness with the base surface (Fig. 57-a).
The laser line will shift to the right in parallel when the Adjuster [88] is turned clockwise, and shift to
the left when turned counterclockwise.
CAUTION: Exercise utmost caution in handling the switch trigger for the position adjustment of
the laser line, as the power plug is plugged into the receptacle during operation.
If the switch trigger is pulled inadvertently, the saw blade can rotate and result in
unexpected accidents.
Do not stare into beam while the laser marker is lighting.
Do not observe beam directly with an optical instrument.
If your eye is exposed directly to the laser beam, it can be hurt.
Instruct the customer not to stare into beam. In addition, instruct the cu stomer not to
give strong impact to the laser marker (m ain body of tool) and not to dismantle the laser
marker. Use of controls or adjustments or performance of procedures other than those
specified in this TECHNICAL DATA AND SERVICE MA NUAL and the Instruction Manual
may result in hazardous radiation exposure.

(2) Adjustment of the laser marker
Adjust the laser marker according to the following steps from 1) to 5).
Adjust the product accuracy first because the accuracy of the laser marker is adjusted aligning the cut
surface of the workpiece.
1) First, hold a workpiece of 60 mm (2-3/8") in height and 150 mm
Fig. 58-a
(5-15/16") in width with the vise and perform right-angle cutting.
At this time, check that Plate (A) [105], Cover (A) [104] and
the inlet of a hex. bar wrench at Hinge (A) Ass’y [87] (Fig. 57-a)
are closed to prevent saw dust from entering the laser marker.
If they are not closed, block them with tapes.
2)
Light up the Laser Marker [107] with the workpiece held in the
vise. Turn the Adjuster [88] to shift the laser line onto the cutting
surface, top edge or rear edge of the cutting surface.
3) Next, insert a 2.5-mm hex. bar wrench into the inlet and adjust
the two Seal Lock Hex. Socket Set Screws M5 x 6 [103] so that
laser beam is applied to the entire cutting surface. (Before
adjustment of the Laser Marker [107] using a 2.5-mm hex. bar
wrench, remove Caution Label (J) [109], Base Rubber [93] and
the tape adhered to the inlet.) If the laser line gets out of the
cutting surface during the laser line adjustment using the two
Seal Lock Hex. Socket Set Screws M5 x 6 [103], turn the
Adjuster [88] to shift the laser line onto the cutting surface, top
edge or rear edge of the cutting surface then adjust the accuracy

Socket Set Screws M5 x 6 [103] and the laser line.
4) To check the accuracy of the Laser Marker [107], move the Laser
Marker [107] horizontally using the Adjuster [88] again and
check that the laser beam is applied to the entire cutting surface.
If the laser beam is applied to the cutting surface in parallel, the
fine fuzz reflects the laser beam and the entire cutting surface
becomes bright.
5) Make a right-angle ink line on the workpieces of 20 mm (13/16")
in height and 150 mm (5-15/16") in width and 60 mm (2-3/8") in
height and 150 mm (5-15/16") in width respectively. Adjust the
laser marker and perform cutting. If the ink line matches the
cutting position, the accuracy adjustment is completed. (Visually
check that the laser marker accuracy is 0.35/100 or less for both
the squareness with the base surface and the squareness with
the fence surface.)
