English
and specifications provided with this power tool.
Failure to follow all instructions listed below may result
in electric shock, fire and / or serious injury.
•
Do not use accessories which are not
specifically designed and recommended by the
tool manufacturer. Just because the accessory can
be attached to your power tool, it does not assure safe
operation�
• The rated speed of the accessory must be at
least equal to the maximum speed marked on the
power tool. Accessories running faster than their
rated speed can break and fly apart.
• The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot
be adequately guarded or controlled�
•
The arbour size of wheels, flanges, backing
pads or any other accessory must properly fit the
spindle of the power tool. Accessories with arbour
holes that do not match the mounting hardware of the
power tool will run out of balance, vibrate excessively
and may cause loss of control�
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive wheels
for chips and cracks, backing pad for cracks, tear or
excess wear, wire brush for loose or cracked wires.
If power tool or accessory is dropped, inspect for
damage or install an undamaged accessory. After
inspecting and installing an accessory, position
yourself and bystanders away from the plane of
the rotating accessory and run the power tool at
maximum no-load speed for one minute. Damaged
accessories will normally break apart during this test time�
• Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and workshop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various operations.
The dust mask or respirator must be capable of filtrating
particles generated by your operation� Prolonged
exposure to high intensity noise may cause hearing loss�
•
Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments of
workpiece or of a broken accessory may fly away and
cause injury beyond immediate area of operation�
• Hold the power tool by insulated gripping
surfaces only, when performing an operation where
the cutting accessory may contact hidden wiring
or its own cord. Cutting accessory contacting a "live"
wire may make exposed metal parts of the power tool
"live" and could give the operator an electric shock�
• 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�
• 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�
• Do not run the power tool while carrying it at your
side. Accidental contact with the spinning accessory
could snag your clothing, pulling the accessory into
your body�
• Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing and
excessive accumulation of powdered metal may cause
electrical hazards�
• Do not operate the power tool near flammable
materials. Sparks could ignite these materials�
• 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 acces-
sory� Pinching or snagging causes rapid stalling of the
rotating accessory which in turn causes the uncon-
trolled 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�
• 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�
• Never place your hand near the rotating
accessory. Accessory may kickback over your
hand�
• 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�
• 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�
• Do not attach a saw chain woodcarving blade
or toothed saw blade. Such blades create frequent
kickback and loss of control�
Safety guidelines during power tool
operation
Safety warnings specific for wire brushing
operations
• Please note that a brush can scatter wire even
during normal work. Do not apply excessive
pressure on the power tool, this will increase
wear and wire scattering. Scattering wire can easily
penetrate light clothes and rip into skin�
• No foreign materials are allowed between the
wire brush and the protective housing.
• Follow recommendations on mounting of brushes -
the direction of the arrow on the brush must be the
same as that on the power tool reducer�
• When processing workpieces of small size or
weight, fix them securely. If workpieces are too small
to be fixed securely, do not process them. Large-size
workpieces must have adequate support, must not
slack, and their ends should not vibrate�
