Mannesmann 12555-STS350 Instruction Manual page 53

 Always use undamaged clamping flanges of the proper size and form for the grinding
disc you choose. Proper flanges support the grinding disc and reduce the danger of disc
breakage. Flanges for cutting discs may be different from flanges for other grinding discs.
 Do not use grinding discs from larger electrical devices. Grinding discs for larger
devices are not designed for the higher rotational speeds of smaller devices and may break.
Further safety guidelines for cutting discs
 Avoid a blockage of the cutting disc or high contact pressure. Do not do any cuts that
are excessively deep. Overstressing the cutting disc increases the strain and the likelihood
of canting or blocking and the possibility of a machine kickback or a breakage of the tool.
 Stay out of the area in front of or behind the rotating cutting disc. If you are moving the
cutting disc away from yourself into the work piece, a kickback could cause the rotating disc
to be forced directly toward you.
 If the cutting disc jams, or if you stop working, turn the device off and hold it until the
disc stops moving completely. Never try to pull a still-rotating cutting disc out of the
cut, as this may result in a machine kickback. Determine and correct the cause for the
machine becoming jammed.
 Never turn the device back on while it is inside the work piece. Allow the cutting disc
to reach its full rotational speed before you begin your cut. Otherwise the disc may
become caught, jump out of the work piece or cause a kickback.
 Support slabs or large work pieces to avoid the risk of kickback resulting from a
jammed cutting disc. Large work pieces can bend under their own weight. The work piece
must be supported on both sides of the disc; in the area of the cut as well as on the edge.
 Exercise special care when doing "plunge cuts" into existing walls or other areas that
are not visible. In such cuts, the cutting disc may cut into gas or water pipes, electrical lines
or other objects and cause a machine kickback.
