1. PRODUCT NAME
Hitachi Disc Sanders, Models S 15SA [150 mm (6")]
S 18SA [180 mm (7")]
2. MARKETING OBJECTIVE
The Models S 15SA and S 18SA are high-power and double-insulated disc sanders with a stand-up design
specially developed to meet customer demands in European and Asian markets.
These disc sanders will make it possible to exploit new markets because they are the first products in our disc
sander line to satisfy this range of demands.
The Models S 15SA and S 18SA have the following features.
1) High-power motor
2) Convenient spindle lock
3) Dust-proof bearing-chamber
3. APPLICATIONS
•Sanding of metal and stone surfaces.
•Preliminary sanding of metal surfaces before painting, rust removal, removing old paint before repainting.
•Finishing of wood surfaces, and reducing projections of joints or assemblies.
•Preliminary sanding of wood surfaces before painting.

4-1. Selling Point Descriptions
1) High-power motor
The Models S 15SA and S 18SA are equipped with high-power motors and are more powerful than similar
products.
We could say that the ratio of the motor's maximum output to the product weight defines its performance.
Compared with typical competitor's models C-1 and C-2 in terms of this indicator, the Models S 15SA and
S 18SA prove to have the higher performance as shown in Table 1.

2) Convenient spindle lock
The Models S 15SA and S 18SA are the first disc sanders in the disc sander industry equipped with a
convenient spindle-lock mechanism.
Thanks to this mechanism, tools can be easily replaced as shown in Fig. 1.

--- 3 ---
3) Excellent overload durability
The Models S 15SA and S 18SA provide excellent overload durability thanks to the improved cooling fan and
cooling air passage design as well as the high-power motor.
Overload durability is defined as the amount of thrust force required to raise the stator coil temperature by 200
K, and the ratio of these models to similar products C-1 and C-2 is indicated in Table 2. Comparing these data,
the Models S 15SA and S 18SA prove to have the excellent overload durability against C-1 and C-2.

Maker HITACHI C-1 / C-2
Model S 15SA / S 18SA
Overload durability ratio 1.2 1
4) New dust seal
Newly-designed dust seals are adopted in the bearing chamber on the commutator side. This ensures better
dust-resistance of the ball bearing in comparison with C-1 and C-2. The key features of the new dust seal are
as follows.
(1) Width is increased to 6.5 mm (C: 2 mm)
(2) 2-step side construction is provided and each step has labyrinth grooves.

6-2. Practical Test Data
1) Comparisons in load vs. rotation speed and stator coil temp. rise
The graph below shows the relationship between the rotation speed and the stator coil temperature rise while
varying loads.
The temperature rise of the Model S 18SA (the Model S 15SA is similar) is lower than that of the similar
product C-2.
And the rotation speed of the Model S 18SA (the Model S 15SA is similar) is higher than that of C-2.
This means that the overload durability and efficiency of the Model S 18SA are superior to C-2.

7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Models S 15SA and S 18SA Disc Sanders 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 Name Plate 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 power tool cannot be completely eliminated.
Accordingly, general precautions and suggestions for the use of the Disc Sander 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. Cautions on Name Plate
The following basic precautions are listed on the Name Plate attached to the main body of each tool.
1) S 15SA
(1) For Taiwan
-- WARNING --
To reduce the risk of injury, the user must read and understand instruction manual.
AVERTISSEMENT
Afin de rèduire le risque de blessures, l'utilisateur doit lire et bien comprendre le
mode d'emploi.
(1) For the U.S.A. and Canada
2) S 18SA
CAUTION
Read thoroughly HANDLING INSTRUCTIONS before use.
(1) For China
7-3. Precautions on Usage
Never press the lock lever while the spindle is rotating:
If the lock lever is pressed while the spindle is rotating, the spindle will stop immediately. In such a case, there is
a danger that the wheel washer may be loosened so that the rubber pad and sanding disc fly off unexpectedly to
cause possible serious injury.

assembly diagram for S 15SA and the <Bold> numbers to those in the Parts List and exploded assembly diagram
for S 18SA.
8-1. Disassembly of the Armature Ass'y and the Lock Lever Ass'y
(1) Loosen the two Brush Caps [23] <23>, and take out the Carbon Brushes [22] <22>.
(2) Remove the four Tapping Screws D5 x 45 [7] <7>, and remove the Gear Cover [8] <8>, and related parts.
The Armature Ass'y [13] <13> can then be taken out together with the Inner Cover [10] <10>, the Lock Lever
[12] <12>, and related parts.
(3) As illustrated in Fig. 3, the Inner Cover [10] <10>, and related parts can be removed from the Armature Ass'y
[13] <13>, and related parts by utilizing a J-130 sleeve (special repair tool, Code No. 970907) and a J-131
plate (special repair tool, Code No. 305711).
(4) The Ball Bearing [11] <11> can be removed from the Armature Ass'y [13] <13> by utilizing the J-30 bearing
puller ass'y (special repair tool, Code No. 970804).
After the Ball Bearing has been removed, the Lock Lever [12] <12> can be easily taken off.
(5) As illustrated in Fig. 4, the Ball Bearing [15] <15> can also be removed from the ArmatureAss'y [13] <13> by

8-4. Reassembly
Reform reassembly in the reverse order of disassembly while ovserving the given precautions and taking care of
the following points.
(1) After disassembly, thoroughly remove old grease from the inside of the Gear Cover [8] <8>, and insert 15 g of
new grease (Nippeco JF-375, Code No. 930036, is recommended) prior to reassembly. When inserting
grease, apply it to the pinion gear teeth surfaces, and to the needle bearing inside the Inner Cover [10] <10>.
(2) When replacing the Ball Bearing [15] <15> on the commutator side of the Armature Ass'y [13] <13>, be very
careful to ensure that the Dust Seal [14] <14> is assembled in the proper direction. The Dust Seal [14] <14>
