POWER TOOL SAFETY

• Read and understand all safety warnings and instructions.
• Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
• Save all warnings and instructions for future reference.

WORK AREA SAFETY

1. Keep the work area clean and well-lit. Cluttered or dark areas invite accidents.
2. DO NOT operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks that may ignite the dust or fumes.
3. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

1. Double-insulated tools are equipped with a polarized plug (one blade is wider than the other).  This plug will fit in a polarized plug only one way.
2. If the plug does not fit fully into the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. DO NOT alter the plug in any way. Double insulation eliminates the need for the three-prong grounded power cord and grounded power supply system.
3. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.
4. DO NOT expose power tools to rain or wet conditions. Water entering the power tool will increase the risk of electric shock.
5. DO NOT abuse the cord. Never use the cord to carry the tool or pull the plug from an outlet. Keep the cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.
6. When operating a power tool outdoors, use an outdoor extension cord marked “W-A” or “W”. These cords are rated for outdoor use and reduce the risk of electric shock.

PERSONAL SAFETY

1. Stay alert, watch what you are doing and use common sense when operating a power tool. DO NOT use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
2. Dress properly. DO NOT wear loose clothing or jewellery.
3. Contains long hair. Keep hair, clothing, and gloves away from moving parts. Loose clothing, jewellery, or long hair can get caught in moving parts.
4. Avoid accidental start-ups. Verify that the switch is in the OFF position before plugging in the tool. Carrying a power tool with a finger on the switch or plugging in a tool that has the switch in the ON position invites accidents.
5. Remove adjusting keys and wrenches before turning the tool ON. A wrench or key that is left attached to a rotating part of the tool may result in personal injury.
6. DO NOT overreach. Keep proper footing and balance at all times. Proper footing and balance allow the operator to maintain better control of the tool in unexpected situations.
7. Use safety equipment. Always wear eye protection.
8. Use a dust mask, non-skid safety shoes, a hard hat, or hearing protection when appropriate.

POWER TOOL SAFETY

1. Use clamps or another practical means to secure and support the workpiece to a stable platform. Holding the work in a hand or against the body is not stable, and may lead to loss of control.
2. DO NOT force the tool. Use the correct tool for the application. The correct tool will do the job better and safer when used at the rate that it was designed to work.
3. DO NOT use a power tool if it cannot be turned ON or OFF using the power switch. A tool that cannot be controlled using the switch is dangerous and must be repaired.
4. Disconnect the plug from the outlet before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of accidental start-ups.
5. When power tools are not in use, store them out of the reach of children or untrained persons. Tools are dangerous in the hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind, and are easier to control.
7. Inspect the tool for misalignment or binding of moving parts, broken parts, and any other condition that may affect the operation of the tool. If it is damaged, have the tool serviced before using it. Many accidents are caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer for this model. Accessories that are suitable for one tool may become hazardous when used with another tool.

SERVICE

• Tool servicing must be performed by qualified personnel. Service or maintenance performed by nonqualified personnel could result in a risk of injury.
• When servicing a tool, use only identical replacement parts. Follow the instructions in the Maintenance section of this Manual.
• The use of unauthorized parts or failure to follow the instructions in the Maintenance section of this Manual may create a risk of electric shock or injury.

SPECIFIC SAFETY RULES

WARNING

1. Know your cordless angle grinder. DO NOT plug in the charger or install a battery in the tool until you have read and understood this Instruction Manual. Learn the tool’s applications and limitations, as well as the specific potential hazards related to this tool. Following this rule will reduce the risk of electric shock, fire, or serious injury.
2. Always wear eye protection. Any power tool can throw foreign objects into your eyes and cause permanent eye damage. ALWAYS wear safety goggles (not glasses) that comply with ANSI safety standard Z87.1. Everyday glasses have only impact-resistant lenses. They ARE NOT safety glasses.
3. Glasses or goggles not in compliance with ANSI Z87.1 could cause serious injury when they break.
4. Always wear gloves to protect your hands from hot sparks.
5. Always wear hearing protection and a dust mask. Use only in well-ventilated areas. The use of personal protective equipment and working in a safe environment will reduce the risk of injury.
6. Always keep your hands out of the path of the grinding disc. Avoid awkward hand positions where a sudden slip could cause your hand to move into the rotating disc.
7. To avoid injury from accidental starting, always remove the battery from the angle grinder before installing or removing grinding discs.
8. The grinding disc and guard must be securely attached as described in this Owner’s Manual before installing a battery in the tool. Failure to do so will increase the risk of serious injury if the grinding disc shatters.
9. Make sure the guard is in good condition and securely installed before operating the grinder.
10. Secure the workpiece. Use clamps or a vice to hold the work when practical. It’s safer than using your hand and it frees both hands to operate the tool.
11. DO NOT clamp the grinder in vice or use it as a fixed grinder.
12. Grinding discs must be stored in a dry location to prevent deterioration.
13. Before attaching the grinding disc, inspect it for visible defects. If it is cracked, chipped or warped do not install it.
14. Use only grinding discs in compliance with ANSI Standard B7.1 and rated for a speed greater than 11,000 RPM.
15. DO NOT remove the soft paper in the centre of the grinding disc.
    • NOTE: If this paper has been previously removed, insert some soft rubber or paper between the grinding disc and the disc flange to prevent damage to the grinding disc.
16. DO NOT alter or enlarge the center hole of the grinding disc as this could result in breaking it.
17. DO NOT over-tighten the clamp nut on the grinding disc. Excessive tightening may cause the disc to crack and possibly shatter during operation.
18. DO NOT use the grinder if the disc flange or clamp nut is missing or if the spindle is bent.
19. Check to make sure any extension cords are clear of the area to be cut. Contact with “live” wires could shock the operator or cause a fire.
20. Always hold the grinder securely with two hands while working and at all times when it is running.
21. Never turn the grinder ON with the grinding disc or any rotating parts touching the work surface
22. Never cover the air vents in the motor housing with your hands while operating the grinder.

IMPORTANT SAFETY INSTRUCTIONS
The warnings, precautions, and instructions discussed in this manual cannot cover all possible conditions and situations that may occur. The operator must understand that common sense and caution are factors that cannot be built into this product but must be supplied by the operator.

WARNING Use only attachments recommended or sold by the manufacturer.

1. DO NOT disassemble the cordless angle grinder. Take it to a qualified professional when service or repair is required. Incorrect reassembly may result in electric shock or fire.

GRINDING

1. Always select and use grinding discs that are recommended for the material to be ground. Make sure that the maximum operating speed of the grinding disc selected is not less than 11,000 RPM.
2. Secure all work before beginning the grinding operation.
3. Secure small workpieces in a vice or clamp to a workbench.
   • WARNING Never use your angle grinder with the guard removed. It has been designed for use only with the guard installed. Attempting to use the angle grinder with the guard removed will result in loose particles being thrown against the operator resulting in serious personal injury.
   • WARNING Never use your angle grinder without eye protection. Following this rule will reduce the risk of serious personal injury.
4. The efficient operation of the angle grinder begins by controlling the pressure and surface contact between the grinding disc and the workpiece. Flat surfaces are ground at an acute angle, normally between 5° and 15° (Fig. 6).
5. For maximum control, hold the angle grinder in front and away from you with both hands, keeping the grinding disc clear of the workpiece. Start your angle grinder and let the motor and grinding disc build up to full speed. Gradually lower the angle grinder until the grinding disc contacts the workpiece.
6. For best results keep the angle grinder tilted at an angle of between 5° and 15° degrees and continuously moving at a steady, consistent pace. Move the angle grinder back and forth or up and down over the work area. Keep the angle grinder moving so that an excessive amount of material is not removed from one area. If the angle grinder is held in one spot too long, it will gouge and cut grooves in the workpiece. If the angle grinder is held at too sharp an angle, it will gouge the workpiece because of the concentration of pressure on a small area.
