1. PRODUCT NAME
Hitachi 355 mm (14") Dry Cut Metal Saw, Model CD 14F
2. MARKETING OBJECTIVE
Generally, high-speed cutters equipped with grindstones are utilized for cutting steel materials in plumbing work
sites. However, these cutters produce sparks and dust during cutting, and steel materials are discolored due to
heat. This is the reason of an increasing demand for a cutter equipped with a tipped saw blade and free from the
above problems. The new Model CD 14F is a highly efficient and long-life dry cut metal saw equipped with a
tipped saw blade for metal cutting. The Model CD 14F is superior to the conventional high-speed cutters in
cutting performance.
3. APPLICATIONS
Cutting soft steel pipes for plumbing
Cutting soft shape steel such as angle steel and channel steel
Cutting soft steel round bars
CAUTION The Model CD 14F cannot cut stainless steel, hardened steel and shape steel less than 2 mm
thick.

4-1. Selling Point Descriptions
(1) Largest cutting dimensions in this class
Item
(2) Equipped with tipped saw blade for metal cutting
The Model CD 14F is far superior to the conventional high-speed cutters (cutting with grindstones) in cutting
performance thanks to the tipped saw blade for metal cutting. This tipped saw blade has a unique relief angle
to cause minor chipping when the cutting edge becomes worn for long-lasting cutting quality, and has about
1.5 times longer service life than those of the competitors. (See page 8, "8.3 Tipped Saw Blade for Metal
Cutting".)

(4) Stopper
The Model CD 14F is equipped with the stopper to cut workpieces at
the same length continuously. The stopper's cutting range is from
38 mm to 228 mm.
<How to use the stopper>
1. Loosen the hex. head socket screw and pull the holder.
2. Loosen the wing bolt and move the stopper to the desired position.
3. Press a workpiece against the stopper and cut it.
(5) Overload protector
The Model CD 14F is equipped with the overload protector that stops
the motor if an abnormal overload is applied to the tipped saw blade
to prevent the motor from being burnt. If this overload protector is
activated, release the trigger switch and remove the cause of trouble.
Wait several minutes until the Model CD 14F cools down, then press
the overload switch to restart the Model CD 14F.
(6) Dust box
The dust box collects cutting dust for ease of cleaning after cutting
operation. As a guide, remove cutting dust at intervals of about 20
times of cutting operation when the workpiece is SGPW65A pipe
(76.3 mm in dia., 4.2 mm in thickness).
(3) Quick-lock vise
The Model CD 14F is equipped with the quick lock vise ass'y that can securely fasten a workpiece just by
tilting the clutch toward vise (A) (to screw-fit the clutch) and turning the screw handle, and quickly release the
vise (A) just by tilting the clutch backward (to release the screw-fitted clutch). Thus the fastening time is
remarkably shortened.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model CD14F Dry Cut Metal 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 nameplate 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 electric tool cannot be completely eliminated.
Accordingly, general precautions for the use of electric power tools, and specific precautions and suggestions for
the use of the model are listed in the Instruction Manual to enhance the safe, efficient use of the machine 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.
7-2. Precautions of the Nameplate
Each Model CD 14F is furnished with a nameplate that lists the following precautions.
(1) Advise the customer to become thoroughly familiar with the contents of the Instruction Manual before
attempting to operate the machine.
(2) Eye protections are intended to prevent chips, dust and sparks from flying into the eyes of the operator during
operation. Carefully caution the customer to wear eye protection whenever operating the machine.
(3) Instruct the customer to thoroughly read the Instruction Manual prior to attempting to operate the machine.
7-3. Warning Label (A)
Warning label (A) specified by UL is affixed on
the upper lefthand portion of the motor
housing. Please instruct customers to strictly
observe the contents from 1 to 10 in warning
label (A) shown at the left.
Fig. 5

--- 7 ---
7-4. Warning Label (B)
Warning label (B) is affixed on the lower portion
of warning label (A).
Please instruct customers to strictly observe the
contents from 1 to 12 in warning label (B)
shown at the left.
Fig. 6
7-5. Grounding Instructions
In the event of a malfunction or breakdown, grounding provides a path of least resistance for electric current to
reduce the risk of electric shock.
This power tool is equipped with an electric cord having an equipment-grounding conductor and a plug with a
grounding pin, as shown in Fig. 7. The plug must be plugged into a matching receptacle that is properly installed
and grounded in accordance with all local codes and regulations.
Do not modify the provided plug if it does not fit the receptacle.
Have a proper receptacle installed by a qualified electrician. Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The equipment-grounding conductor is the one with the green
outer insulation (with/without yellow stripes). If repair or replacement of the electric cord or plug is necessary, do
not connect the equipment-grounding conductor to a live terminal.
Check with a qualified electrician or serviceperson if the grounding instructions are not completely understood, or
if in doubt as to whether the tool is properly grounded.
Use only 3-core extension cords that have 3-prong grounding plugs and 3-pole receptacles that accept the tool's
plug.
Repair or replace damaged or worn cord immediately. This power tool is intended for use on a circuit with an
receptacles similar to the one illustrated in sketch A, Fig. 7. A temporary adapter, similar to the one illustrated in
sketches B and C, may be used to connect the power tool plug to a 2-pole receptacle as shown in sketch B in
case a properly grounded receptacle is not available. The temporary adapter should be used only until a properly
grounded receptacle has been installed by a qualified electrician. The green-colored grounding lug extending
from the adapter must be connected to a permanent ground such as a properly grounded receptacle box.
