Note: This angle grinder, with the proper disc attached, can be used for grinding and cutting steel, stone,
or ceramic workpieces such as pipe, iron, steel bar, bricks, and tiles. Do not attempt to grind wood or a soft
metal such as lead. The material will quickly “fill” the disc and render it useless.
Before starting grinder, first ensure that the disc, disc guard and tool are in good condition. Position the
guard so that it will deflect hot sparks away from the operator.
1) Do not cover exhaust vents when the tool is in use. This may cause damage to the motor and reduce
the efficiency of the tool.
2) Move the grinder across the workpiece in a steady motion.
3) Diamond cutting or grinding wheels are recommended for stone, concrete or masonry.
The best results are achieved with an angle of 30° to 40° for grinding. Move the
tool back and forth with light pressure. In this manner, the workpiece does not
become too hot, discoloration will not occur, and no ridges are produced.
Under no circumstances should a cutting disc be used for grinding.
Maintenance and Inspection:
CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
1) The armature and stator (motor) are the heart of the power tool. Exercise due care to ensure they do
not become damaged or affected by oil or water.
2) The carbon brushes should be checked periodically, and worn-out brushes should be replaced. After
replacing, inspect whether the new carbon brushes can move freely in the brush holder. Keep running
the motor for 15 minutes to match the contact of the carbon brushes and commutator.
3) Regularly inspect all mountings and screws and ensure they are properly tightened. Should any of the
screws be loose, tighten them immediately. Failure to do so may result in serious damage.
4) The supply cord of the tool and any extension cord used should be checked frequently for damage.
Replace the extension cord if necessary.
5) The grease in the gearbox will require replacement after extensive use of the tool.
6) Clean and dust the tool after each use.
Accessories:
CAUTION: These accessories or attachments are recommended for use with your tool specified in this
manual. The use of any other accessories or attachments might present a risk of injury. Only use the
accessory or attachment for its stated purpose.

WARNING: Read and understand all instructions. Failure to follow all instructions listed below may
result in electric shock, fire and/or serious personal injury.
Work Area:
1. Keep your work area clean and well lit. Cluttered benches and dark areas can cause accidents.
2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable
liquids, gases, or dusts. Power tools create sparks which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors 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 outlet only one way. If the plug does not fit fully in the outlet,
reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet.
Do not change the plug in any way. Double Insulation eliminates the need for the three-wire
grounded power cord and grounded power supply system.
2. 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.
3. Don’t expose power tools to rain or wet conditions. Water entering a power tool will increase the
risk of electric shock.
4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet.
Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
5. When operating a power tool outside, 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 when operating a power tool. Do not use tool while tired or under the influence of
drugs, alcohol, or medication, as this may result in serious personal injury.
2. Dress properly. Do not wear loose clothing or jewelry and pull back long hair. Keep your hair,
clothing, and gloves away from moving parts to avoid being caught in the tool.
3. Avoid accidental starting. Be sure switch is off before plugging in the tool. Carrying tools with
your finger on the switch or plugging in tools with the switch on can cause injury.
4. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left
attached to a rotating part of the tool may result in personal injury.
5. Do not overreach. Always keep proper footing and balance. Proper footing and balance enable
better control of the tool in unexpected situations.
6. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat,
or hearing protection may be used for appropriate conditions.
Tool Use and Care:
1. Use clamps to secure and support the workplace to a stable platform. Holding the work by hand
or against your body is unstable and may lead to loss of control.
2. Do not force tool. Use the correct tool for your application. The correct tool will do the job better
and safer at the rate for which it is designed.
3. Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the
switch is dangerous and must be repaired.
4. Disconnect the plug from the power source before making any adjustments, changing
accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the
tool accidentally.
5. Store tools out of reach of children and other untrained persons. Tools are dangerous in the
hands of untrained users.
6. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with
sharp cutting edges are less likely to bind and are easier to control.
7. Check for misalignment or binding of moving parts, breakage of parts, and any other condition
that may affect the tools operation. If damaged, have the tool serviced before using. Many
SAFETY PRECAUTIONS:

6

accidents are caused by poorly maintained tools.
8. Use only accessories that are recommended by the manufacturer for your model. Accessories
that may be suitable for one tool, may become hazardous when used on another tool.
Service:
1. Tool service must be performed only by qualified repair personnel. Service or maintenance
performed by unqualified personnel could result in a risk of injury.
2. When servicing a tool, use only identical replacement parts. Follow instructions in the
Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance
Instructions may create a risk of electric shock or injury.
Additional Safety Regulations:
 Always use the proper guard with grinding or cut-off wheels. A guard protects operator from
broken wheel fragments, sparks, and debris from cutting.
 Hold tool by insulated gripping surfaces when performing an operation where the cutting tools
may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal
parts of the tool “live” and shock the operator.
 Accessories must be rated for at least the speed recommended on the tool warning label. Wheels
and other accessories running over their rated speed can fly apart and cause injury.
 When the machine is in operation, keep hands away from the cutting or grinding area.
 The disc will not stop immediately when the machine is turned off. Exercise caution.
 Do not place the tool down after use until the grinding or cutting wheels have come to complete
stop.
 Do not start the tool when the grinding or cutting wheels are touching the work area.
 Always ensure the safety guard is attached correctly and do not operate the angle grinder without
the guard attached.
 Only use grinding and cutting wheels that are approved for a maximum speed of 11,000 RPM or
greater.
 Only use grinding or cutting wheels with the correct bore size for the spindle of the grinder.
 Keep the power cord away from the cutting area during use. Always position the cord so that it
will not be caught in the workpiece when the grinder is in use.
 Always wear hearing protection, safety glasses and face mask while in operation.
 Before connecting the tool to the power supply follow the safety instructions to install the grinding
or cutting wheels. Installing the nut too tightly can cause the wheel to crack.
 Always use both hands when operating the tool.
 Use the standard parts. Do not use a coolant or water and do not use as a fixed grinder.
