Safety Warnings Specific For Grinding And Abrasive Cutting-Off Operations; Safety Warnings Specific For Wire Brushing Operations - Rubi A230 PRO Manual Del Usuario

installing an accessory, position bystanders and yourself
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.
h) 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.
i) 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.
j) Hold power tool by insulated gripping surfaces, 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.
k) 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.
l) 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.
m) 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.
n) 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.
o) Do not operate the power tool near flammable materials.
Sparks could ignite these materials.
p) 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 accessory. Pinching or
snagging causes rapid stalling of the rotating accessory which in
turn causes the uncontrolled 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.

ORIGINAL INSTRUCTIONS
• 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 over the power tool.
Safety Warnings Specific for Grinding and
Abrasive Cutting-Off Operations:
• 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.
• 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, accidental contact with
wheel and sparks that could ignite clothing.
• 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 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.
• Do not use worn down wheels from larger power tools. Wheels
intended for larger power tools are not suitable for the higher
speed of a smaller tool and may burst.
Additional Safety Warnings Specific for Abrasive
Cutting-Off Operations:
• 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.
• 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.
• 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 occur. Investigate
and take corrective action to eliminate the cause of wheel
binding.
• 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.
• 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.
• 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 wiri.
Safety warnings specific for sanding operations
• Do not use excessively oversized sanding disc paper. Follow
manufacturers recommendations, when selecting sanding
paper. Large sanding paper extending beyond the sanding
pad presents a laceration hazard and may cause snagging,
tearing of the disc, or kickback.

Safety warnings specific for wire brushing operations

• Be aware that wire bristles are thrown by the brush even
during ordinary operation. Do not overstress the wires by
