1. Use the correct tool for the job. This tool was designed for a specific function. Do not modify or alter this tool or use it for an unintended purpose. This tool is NOT suited for
   a. Use on small areas, corners and edges.
   b. Use with wire brushes.
   c. Cutting, roughing or polishing
   d. Wet grinding
   e. Removing wallpaper.
   f. Grinding ceiling textures.

2. Do not use the tool if any parts are damage broken or misplaced. Repair or replace the parts.

ELECTRICAL SAFETY

WARNING! Do not touch or handle a live tool with any part of your body that is wet or damp. Wet skin reduces resistance to electrical current, increasing the danger of a serious or fatal shock.
WARNING! To reduce risk of electric shock, be certain that the plug is connected to a properly grounded receptacle.
WARNING! All wiring should be performed by a qualified electrician.

1. Disconnect tool from power source before cleaning, servicing, changing parts/accessories or when not in use.

8. Grounded tools must be plugged into an outlet that is properly installed and grounded in accordance with all codes and ordinances. Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. If the tool should electronically malfunction or break down, grounding provides a low resistance path to carry electricity away from the user.
   a. Never remove the grounding prong or modify the plug in any way, as this will render the tool unsafe.
   b. Do not use any adapter plugs.

POWER CORD

1. Insert the power cord plug directly to the power supply whenever possible.
   Use extension cords or surge protectors only when the tool’s power cord cannot reach a power supply from the work area.

2. Do not operate this tool if the power cord is frayed or damaged as an electric shock or surge may occur, resulting in personal injury or property damage.
   a. Inspect the tool’s power cord for cracks, fraying or other faults in the insulation or plug before each use.
   b. Discontinue use if a power cord feels more than comfortably warm while operating the tool.
   c. Have the power cord replaced by a qualified service technician.
   3. Keep all connections dry and off the ground to reduce the risk of electric shock. Do not touch plug with wet hands.

3. Prevent damage to the power cord by observing the following:
   a. Do not pull on the cord to disconnect the plug from an outlet.
   b. Keep cord away from heat, oil, sharp edges or moving parts.
   c. Never use the cord to carry the tool.
   d. Place the electrical cord in a position that prevents it from coming into contact with the tool and from getting caught by the workpiece. The cord should always stay behind the tool.

4. Do not allow people, mobile equipment or vehicles to pass over unprotected power cords.
   a. Position power cords away from traffic areas.
   b. Place cords in reinforced conduits.
   c. Place planks on either side of the power cord to create a protective trench.

POWER TOOL PRECAUTIONS

1. DO NOT use any power tool with a malfunctioning power switch or control.
   A power tool that fails to respond to the controls is dangerous and could cause an injury. A qualified technician must repair and verify the power tool is operating correctly before it can be used.

2. Do not allow the tool to run without load for an extended period of time, as this will shorten its life.

3. Do not cover the air vents. Proper cooling of the motor is necessary to ensure normal life of the tool.

4. Avoid unintentional starting. Ensure the switch is off when connecting to the power source.

5. Disconnect the power source before installing or servicing the tool.

6. After making adjustments, make sure that any adjustment devices are securely tightened.

7. Remove adjusting keys and wrenches before using the tool. The tool may eject an attached wrench or a key and cause an injury to you or a bystander.

8. Never force the tool. Excessive pressure could break the tool, resulting in damage to your workpiece or serious personal injury. If your tool runs smoothly under no load, but does not run smoothly under load, then excessive pressure is being used.

9. Only use accessories that are specifically designed for use with the tool.
   Ensure the accessory is tightly installed.

10. Only use an accessory that exceeds the No Load Speed rating (see Specifications).

SANDING PRECAUTIONS

1. Keep hands and fingers away from sanding area. Any part of body coming in contact with moving parts could cause injury.

3. To maintain complete control, firmly hold your sander. Do not place hands over air vents. Proper cooling of the motor is necessary to ensure normal life of the tool.

4. Never force the tool. Excessive pressure could bend or break the sander, resulting in damage to the tool, your workpiece or serious personal injury.
   If your sander runs smoothly under no load, but does not run smoothly under load, then excessive pressure is being used.

5. This tool will not stop moving immediately. Do not lay the tool down or leave it unattended until it has come to a complete stop. A part that is moving could make the tool jump or grab a surface and pull the tool out of your control.

6. Use an appropriate dust respirator when working for an extended period of time. This will help prevent breathing in the fine dust created while working.

7. Do not sand drywall if asbestos is suspected to be present in the material.
   Asbestos fibres can easily become airborne, creating a risk of serious illness if proper precautions are not taken. Hire a professional to test for asbestos before sanding.

VIBRATION PRECAUTIONS

1. This tool vibrates during use. Repeated or long-term exposure to vibration may cause temporary or permanent physical injury. Take frequent breaks when using the tool.
2. If you feel any medical symptoms related to vibrations (such as tingling, numbness, and white or blue fingers), seek medical attention as soon as possible.

   a. Pregnant
   b. Impaired blood circulation to the hands
   c. Past hand injuries
   d. Nervous system disorders
   e. Diabetes
   f. Raynaud’s Disease

KICKBACK PRECAUTIONS

Kickback is a sudden reaction to a pinched or snagged cutting accessory. The tool kicks out and away from the workpiece while the cutting accessory is still active. This can inflict a serious injury on the user or a bystander. Kickback can also damage the tool or workpiece.

1. Maintain a firm grip on the tool and position your body and arms to allow you to resist a kickback. Kickback will propel the tool in the direction opposite to the cutting accessory’s teeth or direction of rotation. A snagged rotary cutting bit may pull the tool out of the grasp of the user.

2. If kickback occurs:
   a. the cutting accessory may pass over a body part, causing a seriously injury;
   b. a rotary bit may wrench the user’s arm causing muscle or joint injuries; and
   c. the tool may strike bystanders.

3. Use clamps or a vice to hold down smaller workpieces.

4. Use special care when working on corners, sharp edges or flexible material. These workpieces have a tendency to snag the cutting accessory.
