1.13 Kickback and related warnings
»Kickback is a sudden reaction to a
pinched or snagged rotating wheel,
sanding disc, grinding stone or any other
accessory�
»Pinching or snagging causes rapid
stalling of the rotating accessory which
in turn causes the uncontrolled tool to
be forced in the direction opposite of the
accessory’s rotation�
»Kickback is the result of tool misuse and/
or incorrect operating procedures or
conditions and can be avoided by taking
proper precautions�
»Maintain a firm grip on the tool and
position your body and arm to allow you
to resist kickback forces� The operator
can control kickback forces, if proper
precautions are taken�

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�
»Do not attach a toothed saw blade� Such
blades create frequent kickback and loss
of control�
»Always feed the bit into the material in
the same direction as the cutting edge
is exiting from the material (which is the
same direction as the chips are thrown)�
Feeding the tool in the wrong direction
causes the cutting edge of the bit to
climb out of the work and pull the tool in
the direction of this feed�
1.14 Safety of grinding tools
»Always try to hold the tool with both
hands during operation�
»Ensure that the workpiece is kept at waist
height where possible� Never use the
tool between the legs whilst sitting on the
floor�
»Ensure that sparks and particles resulting
from use do not create a hazard� Use
screens where appropriate�
»Never bump the grinding stones onto the
workpiece, or let it hit any other objects
while grinding�
»Always allow the tool to run up to full
operating speed before applying it to the
material being worked on�
»Use clamps, or vices to hold the
workpiece� Failure to secure the
workpiece could result in serious personal
injury�
»Do not position your hand in line with and
behind the rotating disc� When the disc,
at the point of operation, is moving away
from your hand, the possible kickback
may propel the spinning wheel and the
tool directly at you�
»Do not restart grinding in the workpiece
until the disc reaches full speed then
carefully re-enter� The disc may bind,
walk up or kickback if the tool is restarted
in the workpiece�

EN

1.15 Safety of sanding tools
»Inspect the sanding disc before use� Do
not use if split or broken�
»Avoid any contact with a moving sanding
disc and always wear gloves when
possible to protect the hands�
»Beware of potentially explosive
atmospheres being caused by dust /
fumes resulting from sanding and used
dust extraction systems where possible�
»Always wear a face mask when using
the sander as protection from airborne
particles of sanded material�
»Avoid disturbing existing dust and
minimize the scattering of dust in the
workplace environment�
»Take steps to control the dust at the point
of emission�
