7. PRECAUTIONS IN SALES PROMOTION
In the interest of promoting the safest and most efficient use of the Models SB 10S2 and SB 10V2 Belt 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 caution 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 tool cannot be completely eliminated. Accordingly,
general precautions and suggestions for the use of the belt 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. Precautions on Caution Plate
Each of the Models SB 10S2 and SB 10V2 is provided with a caution plate which lists basic safety precautions in
its use (illustrated below). 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 Australia, New Zealand, South Africa and Israel
(3) For Taiwan
(4) For China
--- 6 ---
8. DUST COLLECTION
8-1. Dust Collector
This is a system in which the housing is provided with a dust fan on its side so that air pressure from the dust fan
causes grinding dust to be drawn in from the inlet and collected in a dust bag.
8-2. To Maintain Dust Collecting Performance
When moist dust is drawn in, the dust collecting section becomes clogged and impairs dust-collecting
performance. Instruct the customer to operate the equipment in a dry location as much as possible.
A clogged dust bag impairs dust-collecting performance. Instruct the customer to frequently clean the dust
bag.
Overflow of dust in the dust bag impairs dust-collecting performance. Instruct the customer to empty the dust
bag when dust has been collected to about 70 % of bag capacity.
8-3. Others
Should sparks created from sanding smolder in the dust bag after sanding a steel plate etc., there is a risk of
burning. Instruct the customer to always remove sanding dust from the dust bag.

9-6. Insulation Test
On completion of disassembly and repair, measure the insulation resistance and conduct the insulation test
(dielectric strength test).
Insulation resistance: 7 M Ω or higher with DC 500 V megohm tester
Dielectric strength: AC 4,000 V for 1 minute .................... 220 V --- 240 V (and 110 V for the U.K. products)
AC 3,750 V for 1 minute .................... 120 V for the U.S.A. and Canada products
AC 3,000 V for 1 minute .................... 110 V --- 127 V
(except for the U.K., U.S.A. and Canada products)
No flasheover or breakdown shall occur during the test.
9-7. No-load Current Value
After no-load operation for 30 minutes, the no-load current value should be as follows at a frequency of 50/60 Hz.
Note: The sanding belt should be installed and the dial should be set to "5" for no-load operation.
