Preventing pinching
Prevent the cut from becoming constricted and pinching the cutting blade during
the cutting process.
Support the material such that the cut remains open and does not become
constricted during the entire cutting process.
Notes regarding cutting blades
The cutting blade must be suitable for use with the cut-off saw.
The cutting blade must be suitable for the material to be cut.
The speed allowed for the cutting blade must be the same as or higher than
the maximum machine spindle speed.
Mount the cutting blade such that its rotation direction is the same as that of
the machine.
Only use cutting blades with permissible cutting blade diameters.
When using cutting blades with a hole diameter greater than the machine
shaft, use the suitable adapter ring.
Only use undamaged cutting blades.
Ensure that you also follow the instructions of the cutting blade manufacturer.
Do not use cutting blades that have fallen.
Change the cutting blade only when the engine has been turned off.
Always tighten the cutting blade with the specified torque.
Test the new cutting blade for approx. 1 min at maximum speed (without
cutting).
Do not use the side surface of the cutting blade for grinding.
Only use cutting blades with use-by dates that have not expired.
When storing cutting blades, always lay them flat in an area that is protected
from frost.
