2. GENERAL POWER TOOL SAFETY WARNINGS
WARNING Read all safety warnings and all 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.
The term "power tool" in the warnings refers to your mains-operated (corded)
power tool or battery-operated (cordless) power tool.
1) Work area safety
a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b) Do not operate power tools in explosive atmospheres, such as in the
presence of flammable liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
c) Keep children and bystanders away while operating a power tool.
Distractions can cause you to lose control.
2) Electrical safety
a) Power tool plugs must match the outlet. Never modify the plug in any
way. Do not use any adapter plugs with earthed (grounded) power tools.
Unmodified plugs and matching outlets will reduce risk of electric shock.
b) Avoid body contact with earthed or grounded surfaces, such as pipes,
radiators, ranges and refrigerators. There is an increased risk of electric
shock if your body is earthed or grounded.
c) Do not expose power tools to rain or wet conditions. Water entering a
power tool will increase the risk of electric shock.
d) Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the power tool. Keep cord away from heat, oil, sharp edges
or moving parts. Damaged or entangled cords increase the risk of electric
shock.
e) When operating a power tool outdoors, use an extension cord suitable
for outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
f) If operating a power tool in a damp location is unavoidable, use a
residual current device (RCD) protected supply. Use of an RCD reduces
the risk of electric shock.
3) Personal safety
a) 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

4
inattention while operating power tools may result in serious personal injury.
b) Use personal protective equipment. Always wear eye protection.
Protective equipment such as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will reduce personal
injuries.
c) Prevent unintentional starting. Ensure the switch is in the off-position
before connecting to power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your finger on the switch or
energising power tools that have the switch on invites accidents.
d) Remove any adjusting key or wrench before turning the power tool on.
A wrench or a key left attached to a rotating part of the power tool may result
in personal injury.
e) Do not overreach. Keep proper footing and balance at all times. This
enables better control of the power tool in unexpected situations.
f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair,
clothing and gloves away from moving parts. Loose clothes, jewellery or
long hair can be caught in moving parts.
g) If devices are provided for the connection of dust extraction and
collection facilities, ensure these are connected and properly used. Use
of dust collection can reduce dust-related hazards.
4) Power tool use and care
a) Do not force the power tool. Use the correct power tool for your
application. The correct power tool will do the job better and safer at the rate
for which it was designed.
b) Do not use the power tool if the switch does not turn it on and off. Any
power tool that cannot be controlled with the switch is dangerous and must
be repaired.
c) Disconnect the plug from the power source and/or the battery pack
from the power tool before making any adjustments, changing
accessories, or storing power tools. Such preventive safety measures
reduce the risk of starting the power tool accidentally.
d) Store idle power tools out of the reach of children and do not allow
persons unfamiliar with the power tool or these instructions to operate
the power tool. Power tools are dangerous in the hands of untrained users.
e) Maintain power tools. Check for misalignment or binding of moving
parts, breakage of parts and any other condition that may affect the
power tool’s operation. If damaged, have the power tool repaired before
use. Many accidents are caused by poorly maintained power tools.
f) Keep cutting tools sharp and clean. Properly maintained cutting tools with
sharp cutting edges are less likely to bind and are easier to control.
g) Use the power tool, accessories and tool bits etc. in accordance with

5
these instructions, taking into account the working conditions and the
work to be performed. Use of the power tool for operations different from
those intended could result in a hazardous situation.
5) Service
a) Have your power tool serviced by a qualified repair person using only
identical replacement parts. This will ensure that the safety of the power
tool is maintained.
b) Only have the replacement carbon brushes provided replaced by the
after-sales service at your store or by an approved specialist. This will
ensure the power tool remains reliable.
Safety Warnings Common For Grinding Operations
a) This power tool is intended to function as a grinder. Read all safety
warnings, instructions, illustrations and specifications provided with this
power tool. Failure to follow all instructions listed below may result in electric
shock, fire and/or serious injury.
b) Operations such as sanding, wire brushing, polishing or cutting-off are
not recommended to be performed with this power tool. Operations for which
the power tool was not designed may create a hazard and cause personal injury.
c) Do not use accessories which are not specifically designed and
recommended by the tool manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe operation.
d) The rated speed of the accessory must be at least equal to the maximum
speed marked on the power tool. Accessories running faster than their rated
speed can break and fly apart.
e) The outside diameter and the thickness of your accessory must be within
the capacity rating of your power tool. Incorrectly sized accessories cannot be
adequately guarded or controlled.
f) Threaded mounting of accessories must match the grinder spindle thread.
For accessories mounted by flanges, the arbour hole of the accessory must
fit the locating diameter of the flange. Accessories that do not match the
mounting hardware of the power tool will run out of balance, vibrate excessively and
may cause loss of control.
g) Do not use a damaged accessory. Before each use inspect the accessory

6
such as abrasive wheels for chips and cracks, backing pad for cracks, tear
or excess wear. If power tool or accessory is dropped, inspect for damage
or install an undamaged accessory. After inspecting and installing an
accessory, position yourself and bystanders away from the plane of the
rotating accessory and run the power tool at maximum no-load speed for
one minute. Damaged accessories will normally break apart during this test time.
h) Wear personal protective equipment. Depending on application, use face
shield, safety goggles or safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron capable of stopping small
abrasive or workpiece fragments. The eye protection must be capable of
stopping flying debris generated by various operations. The dust mask or
respirator must be capable of filtrating particles generated by your operation.
Prolonged exposure to high intensity noise may cause hearing loss.
i) Keep bystanders a safe distance away from work area. Anyone entering
the work area must wear personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and cause injury beyond
immediate area of operation.
j) Hold power tool by insulated gripping surfaces only, when performing an
operation where the cutting accessory may contact hidden wiring or its
own cord. Cutting accessory contacting a "live" wire may make exposed metal
parts of the power tool "live" and shock the operator.
k) Position the cord clear of the spinning accessory. If you lose control, the
cord may be cut or snagged and your hand or arm may be pulled into the
spinning accessory.
l) Never lay the power tool down until the accessory has come to a
complete stop. The spinning accessory may grab the surface and pull the power
tool out of your control.
m) Do not run the power tool while carrying it at your side. Accidental contact
with the spinning accessory could snag your clothing, pulling the accessory into
your body.
n) Regularly clean the power tool’s air vents. The motor’s fan will draw the
dust inside the housing and excessive accumulation of powdered metal may
cause electrical hazards.
o) Do not operate the power tool near flammable materials. Sparks could

7
ignite these materials.
p) Do not use accessories that require liquid coolants. Using water or other
liquid coolants may result in electrocution or shock.
Kickback And Related Warnings
Kickback is a sudden reaction to a pinched or snagged rotating wheel, backing
pad or any other accessory. Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncontrolled power tool to be forced
in the direction opposite of the accessory’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the workpiece, the
edge of the wheel that is entering into the pinch point can dig into the surface of
the material causing the wheel to climb out or kick out. The wheel may either
jump toward or away from the operator, depending on direction of the wheel’s
movement at the point of pinching. Abrasive wheels may also break under these
conditions.
Kickback is the result of power tool misuse and/or incorrect operating procedures
or conditions and can be avoided by taking proper precautions as given below.
a) Maintain a firm grip on the power tool and position your body and arm to
allow you to resist kickback forces. Always use auxiliary handle, if provided,
for maximum control over kickback or torque reaction during start-up. The
operator can control torque reactions or kickback forces, if proper precautions are
taken.
b) Never place your hand near the rotating accessory. Accessory may
kickback over your hand.
c) Do not position your body in the area where power tool will move if
kickback occurs. Kickback will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
d) Use special care when working corners, sharp edges etc. Avoid
bouncing and snagging the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory and cause loss of control or
kickback.
e) Do not attach a saw chain woodcarving blade or toothed saw blade. Such
blades create frequent kickback and loss of control.

Safety Warnings Specific For Grinding :
a) Use only wheel types that are recommended for your power tool and the
specific guard designed for the selected wheel. Wheels for which the power
tool was not designed cannot be adequately guarded and are unsafe.
b)The grinding surface of centre depressed wheels must be mounted below
the plane of the guard lip. An improperly mounted wheel that projects through
the plane of the guard lip cannot be adequately protected.
c) The guard must be securely attached to the power tool and positioned for
maximum safety, so the least amount of wheel is exposed towards the operator.
The guard helps to protect the operator from broken wheel fragments, accidental
contact with wheel and sparks that could ignite clothing.
d) Wheels must be used only for recommended applications.
e) Always use undamaged wheel flanges that are of correct size and shape
for your selected wheel. Proper wheel flanges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off wheels may be different from
grinding wheel flanges.
f)Do not use worn down wheels from larger power tools. Wheel intended for
larger power tool is not suitable for the higher speed of a smaller tool and may
burst.
3. SPECIFIC SAFETY RULES
-Check that speed marked on the wheel is equal to or greater than the rated
speed of the grinder;
-Ensure that the wheel dimensions are compatible with the grinder;
-Abrasive wheels shall be stored and handled with care in accordance with
manufacturer’s instructions;

considerable vibration or if other defects are detected. If this condition occurs,
check the machine to determine the cause;

9
-Do not use separate reducing bushings or adapters to adapt large hole abrasive
wheels;
-For tools intended to be fitted with threaded hole wheel, ensure that the thread in
the wheel is long enough to accept the spindle length;
-Check that the work piece is properly supported;
-Do not use cutting off wheel for side grinding;
-Ensure that sparks resulting from use do not create a hazard e.g. do not hit
persons, or ignite flammable substances;
-Ensure that ventilation openings are kept clear when working in dusty conditions.

Depending on whether your operation is cutting or grinding, select the correct
protective cover. Failure to use the right cover for operation could result in injury.
When using a grinding or cutting-off wheel, the protective guard must be fitted on
the tool so that the closed side of the cover always points toward the operator.
Install the guard: release the lock lever of the guard and insert it on the gear head,
and turn/adjust in any desired position for maximum performance, then close the

11
lock lever. Make sure that the fastening lever is properly locked after setting the
guard. To remove the protective cover, follow the installation procedure in reverse.
The protective cover can be turned to a desired angle, but not more than 45°on
left side or right side.
Grinding and Surface Processing
In order to grind surface, you should use a coarse abrasive disk with a sunken
centre. You can use the abrasive disks with diameter of 115mm. The maximum
thickness of disks is 6mm.
Mounting the Wheels /Disks
Place the back flange A over the spindle making sure that it fits tight. Place the
grinding disc B on the top of the back flange, ensuring the bore fits into the step of
the flange. Mount the concave recess side of the external flange C over the
spindle. Press the spindle lock button to lock the spindle firmly, then tighten the
external flange with the spanner in clockwise direction. Allow the angle grinder to
run in idle at least 1 minute with the grinding disc correctly assembled, a vibration
disc should be immediately replaced.
