Warning! Read all warnings and instructions.
Failure to follow the below warnings and instructions
may result in electric shock, fire or serious injury.
Keep all warnings and instructions for future
reference.
The term "electric tool" refers to utility power-driven
(wired) electric tools or battery-driven (wireless)
electric tools in all the following warnings.
1. Keep the workplace clean and bright. A disordered and
dark workplace can cause accidents.
2. Do not operate electric tools in an explosive
environment with flammable liquid, gas or dust. Sparks
generated from electric tools can ignite dust or gas.
3. Keep children and bystanders away and operate
electric tools. The operator will lose control of the tool if
he is distracted.
1. The plug of electric tool must match with the socket.
Never modify the plug in any way. Do not use any
conversion plugs for electric tools that need to be
grounded. Unmodified plugs and matching sockets will
reduce the risk of electric shock.
2. Avoid human contact with grounded surfaces such as
pipes, heat sinks and refrigerators. If your body is
grounded, it will increase the risk of electric shock.
3. Do not expose electric tools to rain or humid
environments. Water entering the electric tool will
increase the risk of electric shock.
4. Do not abuse wires. Never use wires to carry, pull the
electric tool or pull its plug. Keep wires away from heat
source, oil, sharp edges or moving parts. Damaged or
entangled cords will increase the risk of electric shock.
5. When using electric tools outdoors, use an external cord
suitable for outdoor use. The cord suitable for outdoor
use will reduce the risk of electric shock.
6. If it is unavoidable to operate electric tools in a humid
environment, a residual current operated protective
device (RCD) should be used. Using RCD will reduce
the risk of electric shock.
1. Stay alert, pay attention to what you are doing and stay
awake when operating electric tools. Do not operate
electric tools when you are tired, or when you are
responding to drugs, alcohol, or treatment. Momentary
negligence when operating electric tools can cause
serious personal injury.
2. Use personal protective equipment. Always wear
goggles. Safety devices, such as the use of dust masks,
non-skid safety shoes, safety helmets, hearing
protection and other devices under appropriate
conditions can reduce personal injury.
3. Prevent accidental start. Ensure that the switch is in the
off position when connecting the power supply and/or
battery box, picking up or carrying tools. Putting a finger
on a switch that has been turned on or inserting a plug
while the switch is on may cause danger.
4. Before turning on the electric tool, remove all adjustment
keys or wrenches. Wrenches or keys left on rotating
parts of electric tools can cause personal injury.
5. Do not stretch your hands too long. Always pay attention
to your footing and body balance. In this way, the
electric tool can be well controlled in unexpected
situations.
6. Dress appropriately. Do not wear loose clothes or
accessories. Keep clothing, gloves and hair away from
moving parts. Loose clothes, accessories or long hair
may be caught in moving parts.
7. If devices for connecting with dust removal and dust
collection equipment are provided, make sure they are
well connected and used properly. Using these devices
can reduce the danger caused by dust.
1. Only use the recommended grinding wheel model and the
guard specially designed for choosing the grinding wheel.
The grinding wheels that are not designed for electric drive
cannot be adequately protected and are not safe.
2.
The guard must be firmly attached on the electric tool and
placed in the safest way. Only the smallest part of the
grinding wheel is exposed to the operator. The guard is
helpful to protect the operator from the risk of the cracked
grinding wheel fragments and accidental contact with the
grinding wheel.
3.
The grinding wheel is only used for the recommended
operation. For example: do not use the side of the cutting
wheel for grinding operation. The force applied to the side
of the grinding wheel may break the grinding wheel.
4. Always choose the undamaged grinding wheel flange
which has proper specification and shape for the selected
wheel. The proper grinding wheel flange can be used to
support the grinding wheel, reducing the breakage
possibility of grinding wheel. The cutting wheel flange can
be different from the grinding wheel flange.
1. Do not abuse electric tools, use appropriate electric tools
according to the purpose. Choosing a properly designed
electric tool will make your work more efficient and safer.
2. If the switch cannot turn on or turn off the power to the
tool, the electric tool cannot be used. Electric tools that
cannot be controlled by switches are dangerous and
must be repaired.
3. Before making any adjustments, changing accessories
or storing electric tools, the plug must be unplugged
from the power supply and/or the battery box must be
disconnected from the tool. This protective measure will
reduce the risk of accidental starting of the tool.
4. Store unused electric tools out of the reach of children,
and do not allow people who are not familiar with
electric tools or those who do not understand these
instructions to operate electric tools. Electric tools are
dangerous in the hands of untrained users.
5. Maintain the electric tools. Check whether the moving
parts are adjusted in place or stuck, check the damage
of the parts and other conditions that affect the operation
of electric tool. If damaged, the electric tool should be
repaired before use. Many accidents are caused by
poorly maintained electric tools.
6. Keep the cutting tools sharp and clean. Well-maintained
tools with sharp cutting edges are not easy to jam and
are easy to control.
7. Use electric tools ~ accessories and tool bits, etc., in
accordance with the instruction manual, considering the
working conditions and the work to be performed. Using
electric tools for operations that are inconsistent with
their purpose may cause danger.
Note: the term “Residual Current Operated Protective
Device (RCD)” can be replaced by the term

Read all safety warnings, instructions, illustrations and
regulations provided with this electric tool. Failure to
understand all the below instructions will result in electric
shock, fire and/or serious injury.
2. It is not recommended to use this electric tool for
operations such as sanding, brushing, polishing or cutting.
It may be dangerous and cause personal injury if you do
not operate the electric tool by following the specified
functions.
3. Accessory selection: please use the accessories
recommended and specially designed by the
manufacturer, otherwise it may cause unsafe operation.
4. The rated speed of accessory must be at least equal to
the maximum speed marked on the electric tool. The
accessory will crack and fly out if its operating speed is
greater than the rated speed.
5.
The outer diameter and thickness of accessory must be
within the rated capacity of electric tool: incorrect accessory
size cannot be adequately protected and controlled.
6. The shaft hole size of the grinding wheel or any other
accessories must be suitable for the spindle of electric
tool to be installed: the balance will be lost during
operation if the accessories whose hole diameter is
unmatched are installed on this electric tool, resulting that
it is out of control and dangerous by excessive vibration.
7.
Do not use the damaged accessories. Check the
accessories before using the tool each time, for example
check if the grinding wheel has fragments and cracks.
Check if the outer flange nut has cracks, tears or
excessive wear. Check whether the electric tool or
accessory is damaged when they are dropped. When
inspecting the attached accessories, keep yourself and
bystanders away from the surface of the rotating
accessories, and operate the electric tool at the maximum
no-load speed indicated on it for 1 min; the accessories
will be cracked during the test if they are damaged.
8.
Wear the protective equipment. Wear the face shield, safety
goggles or safety glasses according to the operation. Please
wear the dust mask, hearing protectors, gloves and work
apron that can block small abrasives or workpiece fragments
during operation. The eye protection cover must be able to
block the flying debris generated in various operations, and
the dust mask or cover can filter the particles generated in
the operation. The hearing loss can be caused if working in
a high-intensity noise for a long time.
9. Keep bystanders a safe distance from the work area.
Anyone entering the work area must wear protective
equipment. The work pieces or the pieces of broken
accessories may fly out and cause injury to bystanders
who are close to the operating area. The exposed metal
parts of electric tool will be charged when the cutting
accessory touches the live wire, and the operator will get
an electric shock.
10. Keep the cord away from the rotating accessories. The
cord may be cut or entangled if it is not properly
controlled, resulting that your hand or arm may be caught
in the rotating accessories.
11. Do not start the electric tool when carrying it. Otherwise, it
may entangle your clothes and cause yourself injury if you
accidentally touch the rotating accessories.
12.
Always clean up the vents of electric tool. The motor fan will
suck dust into the casing during operation, and excessive
metal powder deposits can cause electrical hazards.
13. Do not use accessories that require coolant. It may cause
electric corrosion or electric shock when using water or
other coolants.
14. Do not put down the electric tool until the accessory
completely stops moving. The rotating accessory may
grab the surface and pull the electric tool, making you
lose control of the tool.
15.
Do not operate electric tools near flammable materials.
Sparks may ignite these materials.
16.
You can only operate the electric tool by holding its
insulated grip surface if work in a place where the
cutting accessory may cut the hidden wire or its own
wire. The exposed metal parts of electric tool will be
charged when the cutting accessory touches a live
wire, and the operator will get an electric shock.
Rebound is a sudden reaction force caused by the grinder
accessories or other accessories, these grinder accessories
are out of control because the rapid block happens on the
rotating grinder accessories which get stuck or entangled. The
stuck or entanglement will cause the rotating electric tool to
produce a movement opposite to the rotation direction of
accessory at the stuck point. For example, the grinding wheel
edge that extends into the stuck point may enter the material
surface and cause the grinding wheel to crawl out or rebound
if the grinding wheel is entangled or stuck by the workpiece.
The grinding wheel may fly to or fly away from the operator.
The rebound is caused by the misuse or improper operation
of electric tool, which may be avoided by taking the
appropriate precautions given below.
1. Keep a tight grip on the electric tool, so that your body or
arms are in the correct state to resist rebound force. Always
use the auxiliary handle to maximize the control of rebound
force and torque when starting if there is an auxiliary
handle. The operator can control the reaction torque or
rebound force if the appropriate precautions are taken.
2. Never bring your hand close to the rebounding accessory,
which may rebound and touch your hand.
3.
Do not stand where the electric tool may move when
rebound occurs. The rebound will drive the tool to move
against the movement direction of the grinding wheel at the
entanglement point.
4. Pay attention when working at sharp corner, sharp edge,
etc. to prevent the accessory from bounce and
entanglement. The sharp corner and sharp edge are likely
to entangle the rotating accessories and cause rebound for
loss of control.
5. Do not install saw chain, woodcarving blade or toothed
saw blade. These saw blades will produce frequent
rebound and loss of control.
1.
Only use the recommended grinding wheel model and the
guard specially designed for choosing the grinding wheel.
The grinding wheels that are not designed for electric drive
cannot be adequately protected and are not safe.
2.
The guard must be firmly attached on the electric tool and
placed in the safest way. Only the smallest part of the
grinding wheel is exposed to the operator. The guard is
helpful to protect the operator from the risk of the cracked
grinding wheel fragments and accidental contact with the
grinding wheel.
3.
The grinding wheel is only used for the recommended
operation. For example: do not use the side of the cutting
wheel for grinding operation. The force applied to the side
of the grinding wheel may break the grinding wheel.
4. Always choose the undamaged grinding wheel flange
which has proper specification and shape for the selected
