3.0 Safety warnings

As with all machines, there is a certain amount of hazard involved with the use of this sander. Use the machine with the respect and caution demanded where safety precautions are concerned. When normal safety precautions are overlooked or ignored, personal injury to the operator can result.

1. Read, understand and follow the safety and operating instructions found in this manual. Know the limitations and hazards associated with this machine.

2. Electrical grounding. Make certain that the machine frame is electrically grounded and that a ground lead is included in the incoming electrical service. In cases where a cord and plug are used, make certain that the grounding plug connects to a suitable ground. Follow the grounding procedure indicated in the National Electrical Code.

3. Power on. Before connecting power to the sander, make sure the start switch is in the "OFF" position.

4. Protect yourself. Protect yourself at al l times when operating the wide belt sander. Avoid eye injury by wearing approved safety shields, goggles or glasses at all times (NOTE: Common eye glasses are only impactresistant, they are not safety glasses). Wear protective footwear. Steel toed shoes are recommended because heavy parts can fall off the conveyor table onto feet.

5. Personal protection. Before operating the machine, remove tie, rings, watch and other jewelry and roll up slee ves above the elbows. Remove all loose outer clothing and confine long hair. Protective type footwear should be used. Where the noise exceeds the level of exposure allowed in Section 1910.95 of the OSHA Regulations, use hearing protective devices. Do not wear gloves.

6. Guards. Do not operate the sander with guards off. Keep the guards in place at all times when the machine is running. If removed for maintenance purposes or any other reason, use extreme caution and replace the guards upon completion of the task and before using the machine again. Injury can result from exposure to the machine's internal moving parts.

7. Check damaged parts. Before continuing use of the machine, a guard or other part that is

damaged should be carefully checked to ensure that it will operate properly and safely and perform its intended function. Check for alignment of moving parts, binding of moving parts, breakage of parts, mounting and any other conditions that could affect its operation. A guard or other part that is damaged should be properly repaired or replaced before machine operation continues.

8. Work area. Keep the floor around the machine clean and free of scrap material, saw dust, oil and other liquids to minimize the danger of tripping or slipping. Be sure the table is free of all scrap, foreign material and tools before starting to cut. Mak e certain the work area is well lighted and that a proper exhaust system is used to minimize dust. Powermatic recommends the use of anti-skid floor strips on the floor area where the operator normally stands and that each machine’s work area be marked off. Provide adequate work space around the machine.

9. Operator position. Stand to one side of the conveyor table and make sure no one else is standing in line with the table while feeding into the machine. The wide belt sander operates at high speed and should a part slip, it will exit the machine at a high rate of speed and may res ult in inj uries to anyone sta nding directly in front of the infeed. (Keep conveyor belt clean and check pin-roll adjustments.) Maintain a balanced stance and keep your body under control at all times. Do not overreach or use excessive force to perform any machine operation.

10. Hand safety. Keep hands clear while feeding parts onto the conveyor table. The part will be forced down as it begins to feed into the machine, causing a pinching action between the part and the table. Use caution! Hands should be clear of the stock and the table to avoid pinching. Never reach into a running machine. Turn off electrical power and stop machine before attempting to retrieve parts from within the machine. Contact with internal moving parts can result in loss or injury to fingers, hands and arms.

11. Housekeeping. Before turning on machine, remove all extra equipment such as keys, wrenches, scrap, and cleaning rags aw ay f rom the machine

12. Careless acts. Give the work you are doing your undivided attention. Looking around, carrying on a conversation, and “horseplay” are careless acts that can result in serious injury.

13. Disconnect machine before performing any service or maintenance or when changing

4

blades. A machine under repair should be RED TAGGED to show it should not be used until the maintenance is complete.

any real or implied warranty and holds itself harmless for any injury or damage w hich may result from that use.

14. Maintain tools in top condition. Keep all tools sharp and clean for the best and safest performance, and follow instructions for lubricating and changing accessories. Never stand on the machine. Serious injury could occur if the sander is tipped or if the sanding belt is accidentally contacted.

15. Job completion. The operator of the sa nder is responsible for shutting the machine down when it is not in use. CAUTION: The abrasive belt will coast to a stop in normal conditions, and will only break to a stop when the emergency devices are pressed! IT IS DANGEROUS TO LEAVE A MACHINE UNATTENDED. Persons not familiar with the sander's operation could injure themselves or others. NEVER clean the sander with power "ON" and never use the hands to clear sawdust and debris; use a brush or compressed air.

16. Replacement parts. Use only Powermatic or factory authorized replacement parts and accessories; otherwise the warranty and guarantee is null and void.

17. Misuse. Do not use this Powermatic openend sander for other than its intended use. If used for other purposes, Powermatic disclaims

18. If you are not thoroughly familiar with the operation of wide belt sanders, obtain advice from your supervisor, instructor or other qualified person.

19. Drugs, alcohol, medication. Do not operate this machine while under the influence of drugs , alcoho l, or any med ication.

20. Health hazards. Some dust created by power sanding, sawing, grinding, drilling and othe r c onstruction ac t i vit ies contains chemica ls 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.

• Arsenic and chromium from chemicallytreated lumber.

Your risk from these exposures varies, depending 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.

Familiarize yourself with the following safety notices used in this manual:

This means that if preca utions are not heeded, it m ay result in minor injury a nd/or possible

machine damage.

This means that if precautions are not heeded, it may result in serious injury or possibly even

death.
