English
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 blade,
segmented diamond wheel with a peripheral gap
greater than 10 mm 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 specifi ed for your
power tool and the specifi c 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 specifi ed 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 fl anges that are of
correct size and shape for your selected wheel.
Proper wheel fl anges support the wheel thus reducing
the possibility of wheel breakage. Flanges for cut-off
wheels may be diff erent from grinding wheel fl anges.
f) Do not use worn down wheels from larger power
tools.
A wheel intended for larger power tool is not suitable for
the higher speed of a smaller tool and may burst.
g) When using dual purpose wheels always use the
correct guard for the application being performed.
Failure to use the correct guard may not provide the
desired level of guarding, which could lead to serious
injury.
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 the wheel is binding or when interrupting
a cut for any reason, switch off the power tool
and hold it 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
minimize 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.
g) Do not attempt to do curved cutting.
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, which
can lead to serious injury.
GENERAL SAFETY INSTRUCTIONS
FOR GRINDERS
– Attach the side handle fi rmly, hold the housing and the
side handle with both hands, and support the tool body
securely. (Fig. 2)
– Check that speed marked on the wheel is equal to or
greater than the rated speed of the grinder;
– Ensure that the wheel dimensions are compatible with
the grinder;
– Inspect the grinding wheel before use, do not use
chipped, cracked or otherwise defective products;
– Ensure that mounted wheels and points are fi tted in
accordance with the manufacturer's instructions;
– Ensure that blotters are used when they are provided
with the bonded abrasive product and when they are
required;
– Ensure that the abrasive product is correctly mounted
and tightened before use and run the tool at no-load for
30 seconds in a safe position, stop immediately if there
is considerable vibration or if other defects are detected.
If this condition occurs, check the machine to determine
the cause;
– If a guard is equipped with the tool never use the tool
without such a guard;
– Do not use separate reducing bushings or adapters to
adapt large hole abrasive wheels;
– For tools intended to be fi tted with threaded hole wheel,
ensure that the thread in the wheel is long enough to
accept the spindle length;
– Do not use cutting off wheel for side grinding;
– Ensure that sparks resulting from use do not create
a hazard e.g. do not hit persons, or ignite fl ammable
substances;
