CAUTION
Risk of disc breakage or kickback. Application of excessive pressure causes distortion of the cutting disc.
Sticking or stalling of the cutting disc increases the probability of kickback or disc breakage.
▶ Avoid applying excessive pressure when cutting and don’t allow the cutting disc to stick and stall.
▶ Don’t attempt to make an excessively deep cut.
1. Cutting through thick workpieces should be accomplished, as far as possible, by making a several cuts.
Avoid making excessively deep cuts.
2. Never attempt to cut through more than one workpiece at a time.
3. Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
6.3 Avoiding kickback 9
Kickback is a sudden reaction to a pinched or snagged rotating wheel. Snagging or binding brings the
rotating accessory tool to an abrupt stop. This causes the product to be accelerated in the direction opposite
to the accessory tool’s direction of rotation at the point of binding. For example, if a cutting disc is snagged
or pinched by the workpiece, the edge of the cutting disc entering the pinch point can dig into the surface
of the material causing the cutting disc to climb out or kick back. If this happens the cutting disc moves
toward or away from the operator. The further forward the cutting disc binds, the higher the probability of a
kickback. Cutting discs can also break under these conditions. A kickback is the result of product misuse
and/or incorrect operating procedures or conditions. It can be avoided by taking the proper precautions as
described below.
If the cutting disc binds when the product is cutting in the direction of the ground, the product can jump
forward in an uncontrolled manner.
If the cutting disc binds when the product is cutting vertically, for example in a wall, the product can jump
upward in an uncontrolled manner.
1. Always bring the cutting disc into contact with the workpiece from above, with the throttle trigger fully
depressed.
▶ Allow the cutting disc to contact the workpiece only at a point below its rotational axis.
2. Take special care when inserting the cutting disc in an existing kerf.
7 Care and maintenance
WARNING
Risk of injury. Touching the rotating cutting disc or hot parts of the machine may lead to injury or burns.
▶ Switch the engine off and allow the product to cool down before all maintenance, repairs, cleaning or
servicing.
