1. PRODUCT NAME
Hitachi Compound Saw, Model C 10FCB
2. MARKETING OBJECTIVE
The Model C 10FCB has been newly developed as a successor of the current Models C 10FC, C 10FC2 and
C 10FCA (REXON's OEM products) intended to be manufactured in the factory of Hitachi Koki Group (HKF) to
keep high quality and to adopt Hitachi Koki's original design. Vigorous sales promotion and market share
increases are anticipated with the introduction of the new Model C 10FCB. Although the Model C 10FCB is of the
same construction as the current models basically, the Model C 10FCB employs additional functions including the
following:
Capable of cutting both 2 x 6 and 4 x 4 materials at the right angle at a time without the use of a plate
Capable of narrowing the clearance between the fences thanks to the adoption of the rotary sub fence
3. APPLICA TIONS
Cutting various types of wood workpieces
Cutting workpieces of plywood, decoration panels, soft fiberboard and hard board
Cutting aluminum sashes
4. SELLING POINTS

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model C 10FCB Compound Saw 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 various Caution Plates attached to each machine.
7-1. 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 power 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 compound 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.
(1) Precautions on the name plate
Each Model C 10FCB is furnished with a Name Plate that lists the following precautions.
For the U.S.A. and Canada only
Except the U.S.A. and Canada
Instruct the customer to thoroughly read the Instruction Manual prior to attempting to operate the machine.
(2) Caution plate (A)
(3) Caution plate (B)
--- 6 ---
(4) Caution plate (C)
For the U.S.A. and Canada only
The caution plate (C) specified by the UL is affixed on the upper right-hand portion of the gear case. Please
instruct users to strictly observe the contents 1 to 9 in the caution plate (C) shown above.
8. ADJUSTMENT AND OPERATIONAL PRECAUTIONS
8-1. Cutting A Groove on The Table Insert
A groove has to be cut in the table insert, before starting operation.
Secure a piece of wood about 5-1/2" (140 mm) wide to the table with
the vise assembly, to prevent the breakage of the table insert. 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 table insert.
CAUTION: Do not cut the groove too quickly; otherwise the
table insert might become damaged.
8-2. Confirmation of Saw Blade Lower Limit Position
WARNING: To prevent an accident or personal injury, always turn off the trigger switch and
disconnect the power plug from the receptacle before adjustment.
Check that the saw blade can be lowered 1-5/8" to 1-21/32" (41 mm
to 42 mm) below the table insert. If necessary, adjust as follows:
(1) Loosen the 8 mm lock nut on the 8 mm depth adjustment screw.
(2) Turn the 8 mm depth adjustment screw as necessary to set the
Turn table

insert
lower limit position. The saw blade goes up when the 8 mm
depth adjustment screw is turned counterclockwise and down
when it is turned clockwise.
(3) Once the adjustment is complete, fully tighten the 8 mm lock nut.
NOTE: Before tightening the 8 mm lock nut, confirm that the saw blade is adjusted so that it will not cut into the
table.

8-3. 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. 16).
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 (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 6 mm wing
bolt (B) and move the vise assembly to a position where it will not contact the saw blade.

8-4. Confirmation for Use of Sub Fence
WARNING: In the case of left bevel cutting, turn the sub fence counterclockwise. Unless it is turned
counterclockwise, the main body or saw blade may contact the sub fence, resulting in an
injury.
Sub fence
In the case of direct angle cutting and angle cutting, use the
sub fence. Then, you can realize stable cutting of the
material with a wide back face. In the case of left bevel
cutting, raise the sub fence up as illustrated in Fig. 9 and
then turn it counterclockwise.
Turn.
Fence (B)This power tool is equipped with a sub fence. (See Fig. 1.)
Fig. 8
--- 8 ---
8-5. 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 on extension cords, please refer to the
Instruction Manual.) 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. Saw blade contact with 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.
(3) Press cutting
Like the Model C 10FC2, the Model C 10FCB can be used for press cutting of workpieces up to 59 mm x
144 mm (2-5/16" x 5-21/32") in a single operation by simply pushing the saw blade section (head) downward.
The customer should be cautioned that excessive pressure on the handle will not increase the cutting speed.
On the contrary, excessive pressure may result in reduced cutting efficiency (irregular or rough cutting of the
workpiece), and could also cause overload and subsequent burnout of the motor.
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 saw blade section (head) to its original position. Raising the saw blade section (head)
while the saw blade is rotating may cause unwanted cutting marks on the workpiece.
Techniques to avoid unwanted cutting marks
Uneven and unwanted cutting marks can be avoided throughout the cutting operation by gently and smoothly
pressing down on the handle, so that the entire cutting operation is accomplished in a single uninterrupted
motion.
(4) Miter cutting
Miter cutting is accomplished by turning the table. (For details, please refer to the Instruction Manual.)
(5) Bevel cutting
Bevel cutting of 0 --- 45˚ to the left is accomplished by inclining the saw blade section (head). (For details,
please refer to the Instruction Manual.)
[Caution] When the workpiece is secured on the left side, the
cut-off portion comes to rest on the side of the saw
blade as illustrated in Fig. 8. If the handle is raised
Fixed-side workpiece
Cut-off-side
workpiece
before the saw blade rotation comes to a complete
stop, there is a chance that the cut-off portion of the
workpiece could become jammed against the saw
blade, causing a hazardous condition. Instruct the
customer to ensure without fail that the saw blade
comes to a complete stop before attempting to raise
the handle.
