7.3 Working behavior and working technique
•Forcomplexcuttingprocesses,cuttingdirectionandorderofthecutstobeperformedmustbespeciedinadvance
to prevent pinching of the cut off wheel by the removed part and injury from dropping parts.
• Always hold the power tool with both hands. Have the right hand on the rear handle, the left hand on the top handle.
Firmly grasp the handles with your thumb.
• Operate the power tool at high speed when possible.
• Direction change (cutting radius below 5 m [approx. 15 ft]), side pressure, twisting or tilting of the power tool during
cutting is forbidden.
• When shortening work pieces use a secure support and secure the work piece against slipping and twisting. The
work piece must not be held with your foot or by another person.
• Always be ready for sudden kickback of the work piece and warrant the possibility of securely backing away.
• Make sure that cut off sections cannot fall resulting in injury or property damage.
7.4 Cutting metal
Metals are heated and melted at the point of contact by the fast rotation of the cut off wheel.

• Before cutting, specify and mark the cutting joint, and approach the material with the cut off wheel at medium
speed. Only when the guide groove is cut, continue cutting at full throttle and increased pressure.
• Only cut straight and vertically. Do not tilt or twist.
• For a secure and smooth cut, it is best to pull or to move the power tool in a controlled fashion. When moving the
power tool, do not push the cut off wheel into the material in addition to the thrust caused by the wheel’s rotation.
• Large diameter round rods are best cut in steps.
• Thin tubes can be cut with a single sinking cut.
• Tubes with large diameters should be treated like large diameter rods. To avoid tilting and for better control of the

• Double T carriers or angled steel should be cut in steps.

• Material under stress (supported or material in a wall) always has to be grooved slightly on the compression side
and then cut from the tension side so that the cut off wheel is not pinched.
Always wear breathing protection equipment at dry cutting.
7.5 Cutting Mineral Materials

Recommendation: Use the water connection of the power tool and cut off wheels suitable for wet cutting when
cutting mineral materials.
When cutting with water supply, the dust is reduced, visibility is improved and the cut off wheel service life is increased
by the cooling effect of the water.
