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.
(Maximum output may vary depending on market area.) 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) 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.
5. SPECIFICATIONS Model S 15SA S 18SA Item 150 mm (6") 180 mm (7") Capacity Power source AC single phase 50 or 60 Hz Voltage (V) Current (A) Power input (W) Voltage, current and power input 4,000 /min Rotation speed (no-load)
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.
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.
