• Always bring the cutting disc into contact with the workpiece at right angles. Don't attempt to alter the
line of cut by applying lateral pressure or by bending the cutting disc while cutting is in progress.
• Secure the workpiece. Use clamps or a vice to hold the workpiece in position. The workpiece is thus
held more securely than by hand and both hands remain free to operate the product.
• Secure the workpiece and the part to be cut off in order to prevent uncontrolled movement.
▶ When working with the saw trolley, check before use that the gasoline-powered saw is mounted correctly
on the saw trolley.
▶ Switch the gasoline-powered saw off immediately at the start/stop switch in the event of the saw trolley
throttle cable sticking or if the throttle trigger sticks.
▶ Always apply full throttle when cutting.
6.4.1 Avoiding stalling
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. Support slabs or large workpieces so that the kerf remains open during and after the cutting operation.
6.4.2 Avoiding kickback
1. Always bring the cutting disc into contact with the workpiece from above.
◁ 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.
