CAUTION
• Ensure that the disc rotates freely.
• Do not tighten the disc too much; otherwise, it may break.
WARNING
• When working with small pieces, secure
them with clamps or vices. Never use your hands for this purpose.
While operating the grinder:
• Do not use the power tool near flammable materials.
CAUTION
• Do not turn on the tool when the disc is in
contact with the workpiece.
DANGER
• Do not install a wood-cutting saw blade or
toothed blade. Such blades frequently cause kickbacks and loss of
control.
WARNING
• Use personal protective equipment.
Depending on the application, use a face shield, safety glasses.
As needed, use a dust mask, ear protectors, gloves, and
a workshop apron capable of stopping small abrasive
fragments or pieces of work.
• Eye protection should stop debris generated by various operations.
Dust masks or respirators should filter particles produced during the
operation. Prolonged exposure to high-intensity noise can cause
hearing loss.
WARNING
• Never hold the tool by the power cord; hold
it by the body or the auxiliary handle.
CAUTION
• Hold the tool by insulated parts when
performing operations where there is a risk of contact with hidden
wiring. Contact with a "live" wire will electrify exposed metal parts
and give an electric shock to the operator.
• Never release the power tool until the accessory comes to a
complete stop.
• Never strike the work surface with the disc.
CAUTION
• To achieve a good result during the grinding
process, the angle between the disc and the work surface should be
between 15° and 30°.
DANGER
• When the disc is spinning, do not use the
spindle lock to stop it, as it is very dangerous and can cause injury to
the user.
CAUTION
• Do not touch the disc or the workpiece
immediately after grinding. Wait for them to cool before handling.
Do not attempt to cool them with water or oil.
After operating the grinder
WARNING
• Ensure that the tool is disconnected before
inspecting, adjusting, or changing the disc.
• Do not operate the tool while carrying it at your side.
DANGER
• Sparks produced during grinding can be
hazardous if proper precautions are not taken. Ensure they do not
meet the skin or flammable substances.
• Gradually clean the tool's ventilation grilles. The motor's fan
directs dust into the housing, and excessive buildup of metallic dust
can pose an electrical hazard.
• Do not use accessories that require liquid coolants. The use of
water or other liquid coolants may result in an electric shock.
Kickback
DANGER
Kickback is a sudden reaction to a rotating
wheel, backing plate, brush, or any other accessory that becomes
trapped or snagged. This results in a rapid stop of the rotating
accessory, causing the power tool to be forcefully thrust in the
direction opposite to the rotation of the accessory at the jammed
point.

Safety warnings
When using a cordless angle grinder
For instance, if a grinding wheel becomes snagged or caught by the
workpiece, the edge of the wheel entering the snag point may
penetrate the material's surface, causing the wheel to lift or jump.
The wheel may move toward or away from the operator, depending
on the direction of the wheel's movement at the snag point.
Grinding wheels can also break under these conditions.
Kickback is the result of improper use of the power tool and/or
incorrect operating procedures or conditions, and it can be avoided
by taking the appropriate precautions, as outlined below:
a) Maintain a firm grip on the power tool and position your body
and arm to resist kickback forces. Always use the auxiliary handle, if
provided, to have maximum control over kickback or torque
reaction during startup. The operator can control torque reactions or
kickback forces by taking proper precautions.
b) Never place your hand near the rotating accessory. The accessory
can kick back onto your hand.
c) Do not position your body in the area where the power tool will
move if kickback occurs. Kickback will propel the tool in the
opposite direction of the wheel's movement at the snag point.
d) Exercise special care when working in corners, sharp edges, etc.
Avoid bouncing and snagging the accessory. Corners, sharp edges,
or bouncing tend to snag the rotating accessory and cause loss of
control or kickback.
e) Do not use a chainsaw chain, a wood carving blade, or a serrated
saw blade. Such blades frequently cause kickbacks and loss of
control.
Specific safety precautions for
Grinding operations
a) Use only types of discs recommended for your power tool and
the specific protection designed for the selected wheel. Discs for
which the power tool was not designed cannot be adequately
protected and are unsafe.
b) The grinding surface of depressed-center discs should be
mounted below the lip of the guard. An incorrectly positioned disc
protruding through the lip of the guard cannot be adequately
protected.
c) The guard must be securely attached to the power tool and
positioned for maximum safety to minimize the amount of disc
fragments, accidental contact, and sparks that could ignite clothing.
d) Discs should only be used for recommended applications. For
example, do not grind with the side of a cut-off wheel. Abrasive
discs are intended for peripheral grinding, and lateral forces applied
to these discs may cause them to fracture.
e) Always use undamaged disc flanges that are the correct size and
shape. Proper flanges support the disc, reducing the possibility of
breakage. Flanges for cut-off discs may be different from those for
grinding discs.
f) Do not use worn-out discs from larger power tools. A disc
designed for a larger power tool is not suitable for the higher speed
of a smaller tool and may shatter.
