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 to your side. Accidental contact with
the spinning accessory may snag clothing, pulling the accessory towards your body.
n) Regularly clean the power tool's 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 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,
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 towards 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 an 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 the 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
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 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.
c) Wheels must be used only for recommended applications. For example: do not
grind with the side of the cut-off wheel. Abrasive cut-off wheels are intended for
peripheral grinding; side forces applied to these wheels may cause them to shatter.
d) 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.
e) Do not use worn down wheels from larger power tools. Wheels intended for
larger power tools are 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.
b) Do not position your body in line with and behind the rotating wheel. When
the wheel, at the point of operation, is moving away from your body, the possible
kickback may propel the spinning wheel and the power tool directly at you.
c) When wheel is binding or when interrupting a cut for any reason, switch off
the power tool and hold the power tool motionless until the wheel comes to a
complete stop. Never attempt to remove the cut-off wheel from the cut while
the wheel is in motion otherwise kickback may occur. Investigate and take
corrective action to eliminate the cause of wheel binding.
d) Do not restart the cutting operation in the workpiece. Let the wheel reach full
speed and carefully re-enter the cut. The wheel may bind, walk up or kickback if
the power tool is restarted in the workpiece.
e) Support panels or any oversized workpiece to minimise the risk of wheel
pinching and kickback. Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the line of cut and near the edge
of the workpiece on both sides of the wheel
f)
Use extra caution when making a 'pocket cut' into existing walls or other
blind areas. The protruding wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
Safety Warnings Specific for Sanding
Operations
a) Do not use excessively oversized sanding disc paper. Follow manufacturer's
recommendations, when selecting sanding paper. Larger sanding paper
extending beyond the sanding pad presents a laceration hazard and may cause
snagging, tearing of the disc, or kickback.
Safety Warnings Specific for Wire
Brushing Operations
a) Be aware that wire bristles are thrown by the brush even during ordinary
operation. Do not overstress the wires by applying excessive load to the
brush. The wire bristles can easily penetrate light clothing and/or skin.
b) If the use of the guard is recommended for wire brushing, do not allow any
interference of the wire wheel or brush with the guard. Wire wheel or brush may
expand in diameter due to work load and centrifugal forces.
Additional Grinder Safety
WARNING: When using straight and depressed centre cutting-off wheels (type
41 and 42) plus grinding wheels that grind on the edge only (type 1), a cutting guard or
cut-off guard must be fitted.
WARNING: DO NOT operate a grinder without the appropriate guards in place.
Reset the guard if the work angle or the position of the person operating the machine
changes.
WARNING: Always check for an expiry date of the grinding or cutting disc before
use (remove from tool if necessary). This will be either printed on the label or stamped
on the inner steel ring of the disc. DO NOT use an expired disc as it may shatter in use.
•
The grinding surface of the 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
•
Do not touch grinding or cutting discs after use until they have cooled down
•
Reset the on/off switch of the tool to the 'off' position whenever the power is
interrupted
•
The machine can be subject to overload if too much application force is
exerted. Overload can lead to overheating and damage of the power tool. After use,
continue to run the tool at no-load for several minutes in order to cool it down by
using the fan of the motor
•
When operating the grinder, it is an essential safety requirement that the
correct type of guard is installed for each application to prevent injury.
For example, a cutting guard must be installed when using a cutting or diamond
disc, and a grinding guard must be used with grinding discs
•
Grinding tool accessories must be mounted, used and stored in compliance
with the manufacturer's recommendations
