the housing and excessive accumulation of
powdered metal may cause electrical hazards.
n) Do not operate the power tool near
flammable materials. Sparks could ignite
these materials.
o) Do not use accessories that require liquid
coolants. Using water or other liquid coolants
may result in electrocution or shock.
p)
Your hand must hold on the handle when you
are working. Always use the auxiliary handles
supplied with the tool. Loss of control can cause
personal injury.
FURTHER SAFETY
INSTRUCTIONS FOR ALL
OPERATIONS
KICKBACK AND RELATED WARNINGS
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush 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
20V Cordless Brushless Angle Grinder
blade or toothed saw blade. Such blades
create frequent kickback and loss of control.
ADDITIONAL SAFETY
INSTRUCTIONS FOR
GRINDING AND CUTTING-
OFF OPERATIONS
SAFETY WARNINGS SPECIFIC FOR GRINDING
AND ABRASIVE CUTTING-OFF OPERATIONS:
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. For example:
do not grind with the side of cut-off
wheel. Abrasive cut-off wheels are intended for
peripheral grinding, side forces applied to these
wheels may cause them to shatter.
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.
ADDITIONAL SAFETY
WARNINGS SPECIFIC FOR
ABRASIVE CUTTING-OFF
OPERATIONS:
a)
Do not "jam" the cut-off wheel or apply
excessive pressure. Do not attempt
to make an excessive depth of cut.
Overstressing the wheel increases the loading
and susceptibility to twisting or binding of the
wheel in the cut and the possibility of kickback or
wheel breakage.
