Kickback And Related Warnings - Husqvarna K 535i Manual De Usuario

tool. Accessories running faster than their rated
speed can break and fly apart.
• 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.
• Always use undamaged wheel flanges that are of
correct diameter for your selected wheel. Proper
wheel flanges support the wheel thus reducing the
possibility of wheel breakage.
• Do not use worn down reinforced wheels from larger
power tools. Wheels intended for a larger power tool
are not suitable for the higher speed of a smaller tool
and may burst.
• 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 and flanges must properly
fit the spindle of the power tool. Wheels and flanges
with arbour holes that do not match the mounting
hardware of the power tool will run out of balance,
vibrate ecxessively and may cause loss of control.
• Do not use damaged wheels. Before each use,
inspect wheels for chips and cracks. If power tool or
wheel is dropped, inspect for damage or install an
undamaged wheel. After inspecting and installing the
wheel, position yourself and bystanders away from
the plane of the rotating wheel and run the power
tool at maximum no load speed for one minute.
Damaged wheels 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 shop 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 a broken wheel 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. Cutting
accessory contacting a "live" wire may make
exposed metal parts of the power tool "live" and
could give the operator an electric shock.
• Never lay the power tool down until the accessory
has come to a complete stop. The spinning wheel
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.

Kickback and related warnings

• Kickback is a sudden reaction to a pinched or
snagged rotating wheel. Pinching or snagging
causes rapid stalling of the rotating wheel which in
turn causes the uncontrolled power tool to be forced
in the direction opposite of the wheel'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 line with the rotating
wheel. 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,
segmented diamond wheel with a peripheral gap
greater than 10 mm or toothed saw blade. Such
blades create frequent kickback and loss of control.
• Do not "jam" the 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.
