Kickback And Related Warnings - Ribimex RIBITECH PRM115/501 Manuel D'instructions Et D'utilisation

14- 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.
15- Do not operate the power tool near flammable materials. Sparks could ignite these materials.
16- Do not use accessories that require liquid coolants. Using water or other liquid coolants may result in
electrocution or electric shock.

3.4- Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged rotating disk, 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.
a- Maintain a firm grip on the power tool and position your body and arms 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. The accessory may kickback over your hand.
c- Do not position your body in the area where the power tool will move if kickback occurs. Kickback
will propel the tool in the 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 over the power tool.
3.5- Specific Safety Instructions for grinding and cutting operation
a- Use only disk types that are recommended for your tool and the specific guard designed for the
selected disk. Disks for which the tool was not designed cannot be adequately guarded and are unsafe.
b- 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.
c- Disks must be used only for their recommended applications. For example: do not grind with the side
of the cut-off disk. Abrasive cut-off disks are intended for peripheral grinding; side forces applied to these
disks may cause them to shatter.
d- Always use undamaged disk flanges that are of correct size and shape for your selected disk. Proper
disk flanges support the disk thus reducing the possibility of disk breakage. Flanges for cut-off disks may be
different from grinding disk flanges.
e- Do not use worn out disks from larger power tools. Disks intended for larger power tools are not
suitable for the higher speed of a smaller tool and may burst.
3.6- Specific Safety Instructions for abrasive cutting operations
a- Do not "jam" the cut-off disk or apply excessive pressure. Do not attempt to make an excessive
depth cut. Overstressing the disk increases the loading and susceptibility to twisting or binding of the disk
in the cut and the possibility of kickback or disk breakage.
b- Do not position your body in line with and behind the rotating disk. When the disk, at the point of
operation, is moving away from your body, the possible kickback may propel the rotating disk and the tool
directly at you.
