18.Keep hands in sight and clear of all moving parts and cutting surfaces.

19.All visitors should be kept at a safe distance from the work area. Make your workshop completely safe by using padlocks, master switches, or by removing starter keys.

20.Know the tool you are using; its application, limitations, and potential hazards.

General Electrical Cautions

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

Wire Sizes

Caution: For circuits that are a great distance 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 overheating and burnout, the use of wire sizes for branch circuits or electrical extension cords according to the following table is recommended:

Safety Requirements for Abrasive Sanding Machines

Abrasive sanding can be hazardous to operators and bystanders. Sanding sparks, chips and dust particles thrown off by the sanding disc can cause serious injury if contacted or inhaled. To avoid such injuries you must comply with the following safety requirements:

1.Always wear protective eyewear when operating machinery. Eye wear shall be impact resistant, safety glasses with side shields which comply with ANSI Z87.1. Use of eye wear which does not comply with ANSI Z87.1 specifications could result in severe injury from the breakage of the eye protection.

2.Wear leather safety gloves, arm guards, leather aprons and safety shoes.

3.A dust collection system is recommended. The operator should also wear a dust mask at all times.

4.Additional precautions may be necessary for sanding materials which are flammable or have

other hazardous properties. You should always consult the manufacturer of such materials for instructions on sanding and handling.

5.Do not force or jam the workpiece into the sanding disc.

6.Before sanding, always allow the motor to come up to operating speed, then check the sanding disc for wobble, run-out, or any unbalanced condition. If the disc is not operating accurately and smoothly, immediately stop the motor and make repairs before attempting any sanding operations.

7.Abrasive discs must be stored in a controlled environment . Relative humidity should be 35% to 50% and the temperature should be between 60° and 80° Fahrenheit. Failure to do so could cause premature disc failure.

8.Examine the face of the sanding disc carefully. Excessive sanding that wears down to the backing material can tear the disc. Never use a disc which shows backing, nicks or cuts on the surface or edge, or damage due to creasing or poor handling.

9.When installing a new disc, be certain the disc is accurately centered on the drive wheel. Failure to do so could cause a serious unbalanced condition.

10.Always present the workpiece to the wheel while resting the workpiece firmly on the table. Failure to do so could result in damage to the workpiece or throwing of the workpiece off the wheel.

11.Safety shoes which comply with ANSI Z41.1 should be worn.

12.Personal hearing protection such as ear plugs or ear muffs should be used to protect against the effect of noise exposure.
