Safety Warnings and Precautions

WARNING: When using tool, basic safety precautions should always be followed to reduce the risk of personal injury and damage to equipment.

Read all instructions before using this tool!

1. Keep work area clean. Cluttered areas invite injuries.

2. Observe work area conditions. Do not use machines or power tools in damp or wet locations.

Don’t expose to rain. Keep work area well lighted. Do not use electrically powered tools in the presence of flammable gases or liquids.

3. Keep children away. Children must never be allowed in the work area. Do not let them handle machines, tools, or extension cords.

4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit rust.

Always lock up tools and keep out of reach of children.

5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do the work of a larger industrial tool. There are certain applications for which this tool was designed.

It will do the job better and more safely at the rate for which it was intended. Do not modify this tool and do not use this tool for a purpose for which it was not intended.

6. Dress properly. Do not wear loose clothing or jewelry as they can be caught in moving parts.

Protective, electrically non-conductive clothes and non-skid footwear are recommended when working. Wear restrictive hair covering to contain long hair.

7. Use eye protection. Always wear ANSI approved impact safety goggles. Wear a full face shield if you are producing metal filings or wood chips. Wear an ANSI approved dust mask or respirator when working around metal, wood, and chemical dusts and mists.

8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or across running machines.

9. Maintain tools with care. Keep tools clean for better and safer performance. Follow instructions for changing accessories. Inspect tool periodically and if any part appears broken or damaged, have it repaired by an authorized technician. The handles must be kept clean, dry, and free from oil and grease at all times.

10. Disconnect power. Disconnect tool from air compressor when not in use and before changing accessories, maintaining, repairing, or cleaning.

11. Remove adjusting keys and wrenches. Check that adjusting wrenches are removed from the tool or machine work surface before connecting it to its power source.

12. Avoid unintentional starting. Be sure the air compressor switch is in the Off position when

not in use and before connecting to this tool. Do not carry any tool with your finger on the trigger, whether it is connected or not.

13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool when you are tired.

14. Take caution as some woods contain preservatives such as copper chromium arsenate

(CCA) which can be toxic. When cutting these materials extra care should be taken to avoid inhalation and minimize skin contact.

15. Check for damaged parts. Before using any tool, any part that appears damaged should be carefully checked to determine that it will operate properly and perform its intended function.

Check for alignment and binding of moving parts; any broken parts; and any other condition that may affect proper operation. Any part that is damaged should be properly repaired or replaced by a qualified technician. Do not use the tool if the trigger does not operate properly.

16. Guard against electric shock. Prevent body contact with grounded surfaces such as pipes, radiators, ranges, and refrigerator enclosures.

17. Replacement parts and accessories. When servicing, use only identical replacement parts.

Use of any other parts will void the warranty. Only use accessories intended for use with this tool. All accessories used must be rated 18,000 RPM or greater. Before each use, inspect the accessory for damage or excess wear. Never use a damage or worn out accessory.

18. Do not operate tool if under the influence of alcohol or drugs. Read warning labels on prescriptions to determine if your judgment or reflexes are impaired while taking drugs. If there is any doubt, do not operate the tool.

19. Use proper size and type extension cord. If an extension cord is required for the compressor, it must be of the proper size and type to supply the correct current to the tool without heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical damage to the tool.

20. Maintenance. For your safety, service and maintenance should be performed regularly by a qualified technician.

21. Use clean, dry, regulated, compressed air at 90 PSI. Do not exceed the recommended

90 PSI. Never use oxygen, carbon dioxide, combustible gases, or any other bottled gas as a power source for this tool.

22. This tool has no safety shield. DO NOT USE GRINDING DISCS, GRINDING WhEELS OR

CUT-OFF WhEELS WITh ThIS TOOL.

Note: Performance of the compressor powering this tool (if powered by line voltage) may vary depending on variations in local line voltage. Extension cord usage may also affect compressor performance.

WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities, contain chemicals known [to the State of California] to cause cancer, birth defects or other reproductive harm. Some examples of these chemicals are:

*Lead from lead-based paints

*Crystalline silica from bricks and cement or other masonry products

*Arsenic and chromium from chemically treated 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 specially designed to filter out microscopic particles. (California health & Safety Code 25249.5, et seq.)

Sanding

Step 1: Identify the area you will be sanding. Make sure you are using the appropriate grit sandpaper for the material you will be working with.

Step 4: You can vary the speed of the Sander/Drill to suit different sanding applications by varying the pressure placed on the TRIGGER.

Step 5: It is recommended that you sand in a random pattern to avoid sanding a side to side into your work surface. Do not sand any one area too heavily, or for more than a few seconds at a time.

Step 6: Every few minutes during continuous sanding, check the condition and wear of the sandpaper. If necessary, peel and replace the sandpaper. Do not use torn or severely worn sandpaper, you may damage your work surface or suffer physical injury.

Step 7: When you are done sanding, remove the Sander/Drill from the work surface and release pressure on the TRIGGER to stop the Sander/Drill.

MAINTENANCE

Your Sander/Drill is best operated with an Airline Oiler. If you are using the Sander/Drill without an Airline Oiler, follow the steps below for maintenance.

Step 1: Disconnect the Sander/Drill from the air hose.

Step 2: Apply a few drops of PNEUMATIC TOOL

OIL through the air line before each use, or every hour if used continuously.

Step 3: Apply a few drops of oil to the TRIGGER

(10) as shown in Figure 6. Work the

TRIGGER a few times to lubricate.

CAUTION

Do not use detergent oil or additives as these lubricants will cause accelerated wear to the seals in the tool.
