▪
If, for instance, a cutting disc becomes locked or jammed in the work piece, the
edge of the disc may fracture inside the work piece and cause a violent kickback.
The disc will them move away from or towards the operator, depending on the
direction of rotation on the locking point. This may also shatter the disc.
▪
Kickback is caused by wrong or inappropriate use of the tool and can be avoided
by following the safety advice below.
▪
Hold the electric tool tightly with both hands and assume a position, in which
you can compensate a kickback. If present, use the accessory handle to be able
to control kickback and countermovement of the running motor. With the
necessary precautions the operator can control all forces of kickback and
countermovement.
▪
Keep your hand away from the spinning attachment. A kickback can throw the
attachment onto your hand.
▪
Keep your body out of the area into which the tool is thrown by a kickback. The
tool is thrown into the direction reverse to the direction of the disc at the locking
point.
▪
Use extreme care when working around edges or sharp corners. Make sure the
attachment cannot become locked into or bounce back from the work piece.
Rotating discs tend to lock into or bounce back from edges and corners. This may
cause kickback or loss of control.
Additional Safety Notes for Grinding and Cutting
▪
Always use the safety hood intended for the kind of attachment you are using.
The safety hood must be securely attached and be adjusted in such a way that
the highest possible degree of safety is achieved, e.g. the smallest possible part
of the spinning attachment pointing to the operator is free. The safety hood is
intended to protect the operator from flying debris, fragments of a fractured disc
and accidental contact with the attachment.
▪
Use only discs intended for your electric tool and the safety hood intended for
these discs. Discs not intended for the electric tool cannot be covered in a
suitable way and are unsafe.
▪
Use discs only for the purpose they are intended for by the manufacturer. Never
use the side of a cutting disc for grinding. Cutting discs are intended for cutting
only. Lateral forces may cause fracture.
▪
The grinding surface of the centre depressed wheels must be mounted below
the plane of the safety hood edge. An improperly mounted wheel that projects
through the plane of the safety hood edge cannot be adequately protected.
▪
Do not attach a saw chain woodcarving blade or toothed saw blade. Such blades
create frequent kickback and loss of control.
