Additional Safety Instructions For Grinding And Cutting-Off Operations - Ratio AR1050NM Manual De Instrucciones

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 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.
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 or toothed saw blade. Such blades create
frequent kickback and loss of control.
ADDITIONAL SAFETY INSTRUCTIONS FOR
GRINDING AND CUTTING-OFF OPERATIONS
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 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
operator from broken wheel fragments and accidental contact with wheel and sparks that could
ignite clothing.
d) Wheels must be used only for recommended 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 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.
f) Do not use worn down wheels from larger power tools. Wheel intended for larger power tool is
not suitable for the higher speed of a smaller tool and may burst.
ADDITIONAL SAFETY INSTRUCTIONS FOR
CUTTING-OFF OPERATIONS
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
