▶ 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 wiring or objects that can cause kickback.
▶ Do not attempt to do curved cutting. 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, which
can lead to serious injury.
Safety warnings specific for sanding operations:
▶ Use proper sized sanding disc paper. Follow manufacturers recommendations, when selecting
sanding paper. Larger sanding paper extending too far 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 applying excessive load to the brush. The wire bristles can easily penetrate
light clothing and / or skin.
▶ If the use of a guard is specified for wire brushing, do not allow any interference of the wire wheel
or brush with the guard. Wire wheel or brush may expand in diameter due to work load and centrifugal
forces.

treated wood; asbestos or materials that contain asbestos. Determine the exposure of the operator and
bystanders by means of the hazard classification of the materials to be worked. Implement the necessary
measures to restrict exposure to a safe level, for example by the use of a dust collection system or by
the wearing of suitable respiratory protection. The general measures for reducing exposure include:
▶ working in an area that is well ventilated,
▶ avoidance of prolonged contact with dust,
▶ directing dust away from the face and body,
▶ wearing protective clothing and washing exposed areas of the skin with water and soap.
