7.1 Cut-Off Wheels
7.2 Permissible cutting area and danger from kickback or pinching
For processing of metals (hot cutting) and processing of mineral materials (cold cutting), different cut off wheels are
offered. Only use cut off wheels approved for the material being cut.Diamond cut off wheels are only approved for
cutting mineral materials. When installing the diamond cut off wheel, always observe the rotating direction indicated on
the diamond cut off wheel; otherwise, the cutting effect will reduce quickly from diamond loss.
Rotating direction of the cut off wheel in the installed condition: Chap. 5.1, page 16
Abrasive resin cut off wheels must not be exposed to moisture. The water connection for wet cutting must not be used
when using abrasive resin cut off wheels. Abrasive resin cut off wheels must not be used in high humidity or in rain.
The power tool’s spindle is designed for cut off wheels with an arbor of 20 mm.Cut off wheels with a 1” arbor must only
be installed with the spindle adapter disk supplied with the power tool.
Installation of cut off wheels with 1” arbor: Chap. 5.2, page 17
-Cut off wheels with other arbor sizes must not be installed! Never modify the arbor of the cut off wheel!

process. No body parts must be located in the extended swivel range of the cut off wheel.
Only use cut off wheels that correspond to the standards ANSI B7.1, EN 12413 and EN 13236 and that are
undamaged.
The maximum spindle speed of the power tool is 4,550 min-1 [4,550 RPM].
Only use high speed reinforced cut off wheels marked with a permissible maximum operating speed of at least
4,550 min-1 [4,550 RPM].
The upper part of the cut off wheel must not
be used for cutting!
Only the lower part of the cut off wheel
must be used for cutting!
Danger of injury from kickback! Kickback results when the upper part of the cut off wheel is used for cutting. The
power tool is pushed towards the user’s head uncontrolledly and at high speed
• Never cut with the upper area of the cut off wheel!
• Take special care at insertion into cutting areas already started!
Danger of injury from pinching!
Pinching results when the cutting point becomes more narrow (crack or tensioned work piece).
The power tool is accelerated forwards uncontrolledly and under high energy.
• Always perform cutting and repeated insertion into cutting points already started at the maximum speed.
• Always support the work piece so that the cutting point is under tension so that the cut off wheel is not clamped
when cutting any further.
• When starting cutting, carefully move the cut off wheel to the work piece; do not apply it suddenly.
• Never cut several work pieces at once!
• Ensure that no other work piece is touched when cutting.
