If this is not possible, please bring the product to Hilti Service.

6 Types of work
6.1 Cutting techniques 9
There is a risk of kickback if the gasoline-powered saw comes into contact with the working surface in the
area indicated.
Kickback is the result of product misuse and/or incorrect operating procedures or conditions. To prevent
kickback, follow the safety instructions and the instructions for use below.
▶ Do not bring the accessory tool into contact with the working surface in the area marked.
▶ Allow the gasoline-powered saw to reach full speed before starting the cut.
▶ Apply pressure to the product so that the accessory tool enters the material slowly.
▶ Apply moderate pressure, adjusting the rate of advance to suit the material being cut.
A decrease in the rate of cutting progress may be an indication of blunt/dull (“polished”) diamond
segments. The diamond segments can be resharpened by making a few cuts in an abrasive
material (Hilti sharpening plate or sand-lime block).
▶ Guide the gasoline-powered saw smoothly and without applying lateral pressure to the cutting disc.
▶
Always hold the gasoline-powered saw and the saw trolley firmly with both hands on the grips provided.
Keep the grips dry, clean and free from oil and grease.
▶ Make sure there is no-one in the working area and, in particular, in the direction in which the cut is to be
made. Keep everyone approx. 15 m away from your workplace.
6.2 Avoiding stalling 8
If the cutting disc binds, the product tends to pull away from the operator.
