General
•Cutting blades are available in two basic designs;
abrasive blades and diamond blades.
• High-quality blades are often most economical. Lower quality
blades often have inferior cutting capacity and a shorter service
life, which results in a higher cost in relation to the quantity of
material that is cut.
• Make sure that the right bushing is use d for the cutting blade to
be fitted on the machine. See the inst ructions under the heading
Fitting the cutting blade.

Blade vibration
•The blade can become out-of-round and vibrate if an
excessive feed pressure is used.
• A lower feed pressure can stop the vibration.
Otherwise replace the blade.
If you use Abrasive Blades
•The cutting material on abrasive blades consists of
grit bonded using an organic binder. ”Reinforced
blades” are made up of a fabric or fibre base that
prevents total breakage at maximum working speed if
the blade should be cracked or damaged.
• A cutting blade’s performance is determined by the
type and size of abrasive corn, and the type and
hardness of the bonding agent.
• Ensure the cutting blade is not cracked or damaged.
• Test the abrasive blade by hanging it on your finger
and tapping it lightly with a screwdriver or the like. If
the blade does not produce a resonant, ringing sound
it is damaged.
