General
WARNING! A cutting blade may burst and
!
cause injury to the operator.
•
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.

Cutting blades for different materials
WARNING! Never use a cutting blade for any
!
other purpose than that it was intended for.
Cutting plastics with a diamond blade can
cause kickback when the material melts due
to the heat produced when cutting and
sticks to the blade. Never cut plastic
materials with a diamond blade!
Cutting in metal generates sparks that may
cause fire. Do not use the machine near to
ignitable substances or gases.
Follow the instructions supplied with the cutting blade
concerning the suitability of the blade for various applications,
or consult your dealer in case of doubts.

Hand-held, high-speed machines
WARNING! Never use a cutting blade at a
!
lower speed rating than that of the power
cutter. Only use cutting blades intended for
high speed handheld power cutters.
•
Our cutting blades are manufactured for high-speed,
portable power cutters.
•
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.
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.
Abrasive blades
WARNING! Do not use abrasive blades with
!
water. The strength is impaired when
abrasive blades are exposed to water or
moisture, which results in an increased risk
of the blade breaking.
•
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 blade it not cracked or damaged in any other
way.
