General Electrical Cautions

This saw should be grounded in accordance with the National Electrical Code and local codes and ordinances. This work should be done by a qualified electrician. The saw should be grounded to protect the user from electrical shock.

Wire Sizes

Caution: For circuits which are far away from the electrical service box, the wire size must be increased in order to deliver ample voltage to the motor. To mini- mize power losses and to prevent motor overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is recommended.

1.Always wear leather gloves when handling saw blade. The operator shall not wear gloves when operating the machine.

2.All doors shall be closed, all panels replaced, and other safety guards in place prior to the machine being started or operated.

3.Be sure that the blade is not in contact with the workpiece when the motor is started. The motor shall be started and you should allow the saw to come up to full speed before bringing the saw blade into contact with the workpiece.

4.Keep hands away from the blade area. See Fig- ure A.

5.Remove any cut off piece carefully while keeping your hands free of the blade area.

6.Saw must be stopped and electrical supply must be cut off before any blade replacement or adjust- ment of blade support mechanism is done, or be- fore any attempt is made to change the drive belts or before any periodic service or maintenance is performed on the saw.

7.Remove all loose items and unnecessary workpieces from the area before starting machine.

8.Bring adjustable saw guides and guards as close as possible to the workpiece.

9.Always wear protective eye wear when operating, servicing, or adjusting machinery. Eyewear shall be impact resistant, protective safety glasses with side shields complying with ANSI Z87.1 specifica- tions. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in se- vere injury from breakage of eye protection. See

Figure B.

10.Nonslip footwear and safety shoes are recom- mended. See Figure C.

11.Wear ear protectors (plugs or muffs) during e x - tended periods of operation. See Figure D.
