Cutting Blades - Husqvarna K 3000 Operator's Manual

Cutting blades

WARNING! A cutting blade may burst
!
and cause injury to the operator.
Never use a cutting blade at a lower
speed rating than that of the power
cutter.
Never use a cutting blade for any other
materials than that it was intended for.
General
• Cutting blades are available in two basic designs;
abrasive baldes 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 used for the cutting
blade to be fitted on the machine. See the instructions
under the heading Assembling the cutting blade.

Special blades
Some cutting blades are designed for stationary
equipment and for use with attachments.Such cutting
blades must not be used on portable power cutters.
Always contact local authorities and make sure you are
following applicable directives.
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. The blade must be of the
recommended type for the material to be cut.
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.
Check that the blade is approved for the same or higher
speed according to the aproval plate of the engine. Never
use a cutting blade with a lower speed rating than that of
the power cutter.
Ensure the blade it not cracked or damaged in any other
way.
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.
