20.Some dust created by power sanding, sawing, grinding, drilling and other construction activities contains chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:
Lead from lead based paint
crystalline silica from bricks and cement and other masonry products, and
arsenic and chromium from
21.Your risk from those exposures varies, depend- ing on how often you do this type of work. To reduce your exposure to these chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specifically designed to filter out microscopic particles.
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 minimize power losses and to prevent motor overheat- ing and burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is recommended:
Conductor length | AWG (American wire gauge) number | |
| 240 volt lines | 120 volt lines |
No. 14 | No. 14 | |
No. 14 | No. 12 | |
Over 100 feet | No. 12 | No. 8 |

Safety instructions on sawing systems
6
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 all 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 to full speed before bringing the workpiece into the saw blade.
4.Keep hands away from the blade area. See
figure 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 adjustment of blade support mechanism is done, or before any attempt is made to change the drive belts or before any periodic service or maintenance is per- formed on the saw.
7.Remove all loose items and any unnecessary work pieces from the area before starting machine.
8.Bring adjustable saw guides and guards as
close as possible to the work piece.
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 specifications. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from breakage of eye protection. See figure B.
10.
11.Wear ear protectors (plugs or muffs) during extended periods of operation. See figure D.
12.The workpiece, or part being sawed, must be securely clamped before the saw blade enters it.
13.Remove cut off pieces carefully, keeping hands away from sawblade.
14.Saw must be stopped and electrical supply cut off or machine unplugged before reaching into cutting area.
15.Avoid contact with coolant, especially guarding your eyes.
