4-1. Selling Point Descriptions
(1) Rapid cutting speed (6.3 m/min):
As shown in the table below (based on comparative cutting of 1.6 mm [1/16"] mild steel plate), the cutting
speed of the Model CE 16SA is the fastest in this class of hand shears. This is because of the high stroke
speed of the piston during actual cutting operation; the more powerful motor minimizes stroke speed loss
when the load is increased. The much higher cutting speed of the Model CE 16SA in comparison with B and
C.
For further details concerning the relationship between the cutting speed and the number and the length of the
piston strokes, refer to the explanation of cutting speed below.
(NOTE) Actual cutting speeds may vary depending on the hardness of the workpiece material, the skill of the
operator, and other variables.

From the formulae above, it can be clearly seen that increases in the values of "N" and "H" will result in faster
cutting speeds. However, it should be noted that the amount to which these values can be increased is
limited by the bounds of existing design technology. In addition, please note that there is very little difference
in the value of the constant "C" among the various manufacturers.

(3) Throw-away type blade (Easily replaceable blades have 8 cutting edges):
The Model CE 16SA, on the other hand, utilizes a throw-away blade system that eliminates the bothersome
and time-consuming regrinding of blades. When the edge of the blade becomes worn or damaged, simply
rotate the blade unit 90˚ to expose a sharp, new cutting edge. In addition, the reversible blade units utilized on
the Model CE 16SA have a total of 8 usable cutting edges - 4 on the front, and 4 on the back. As a single
cutting edge is capable of cutting approximately 400 meters of 1.6 mm [1/16"] mild steel plate, one blade unit
permits cutting of up to 3,200 meters (10,480 feet). While B utilizes a throw-away type blade, it has only 4
usable cutting edges.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Model CE 16SAHand Shear 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 Handling Instructions, and fully understands the meaning of the
precautions listed on the nameplate attached to each tool.
7-1. Handling Instructions
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 and suggestions for the use of the hand shear are listed in the Handling Instructions to
enhance the safe, efficient use of the tool by the customer. Salespersons must be thoroughly familiar with the
contents of the Handling Instructions to be able to offer appropriate guidance to the customer during sales
promotion.
7-2. Precautions on Nameplate
Each Model CE 16SA is provided with a nameplate which lists basic safety precautions (illustrated below) in its
use. Carefully ensure that the customer fully understands and follows these precautions before using the tool.
(1) For the U.S.A. and Canada
(2) For other countries

--- 7 ---
7-3. Efficient Cutting Procedures
Instruct the customer in the following techniques so that
most efficient cutting operations can be achieved.
When cutting thin workpieces (1 mm [.039"] or less) with
a hand shear, the main body of the tool should be kept
parallel with the surface of the workpiece. However,
when cutting thicker workpieces (more than 1 mm
[.039"]), the procedures described below will ensure
smooth and efficient cutting operations.
(1) As illustrated in Fig. 2, the tail portion of the main
body of the tool should be lifted slightly when the cut-
off side of the workpiece is on the left side of the tool.
(2) As illustrated in Fig. 3, the tail portion of the main
body of the tool should be lowered slightly when the
cut-off side of the workpiece is on the right side of the
tool.
Lift slightly

Lower slightly Cut-off side

7-4. Blade Service Life
Blade replacement and service life are described in the Handling Instruction as illustrated in Fig. 4 below. The
service life described is approximate and is based on straight line cutting of 1.6 mm [1/16"] mild steel plate
material with an even, clean surface. Less favorable cutting conditions may cause the service life of the blade to
be slightly shortened.
