Cutting Blades; General; Abrasive Blades - Husqvarna K970 II Rescue Manuel D'utilisation

General

WARNING! A cutting blade may burst
!
and cause injury to the operator.
• 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 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 materials than what it was
intended to cut.
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 metal generates sparks that may
cause fire. Do not use the machine near
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.

* CAUTION! Only specialty blades.
Hand held, high speed machines
WARNING! Never use a cutting blade
!
with a lower speed rating than that of the
power cutter. Only use cutting blades
intended for high speed handheld power
cutters.
• Husqvarna 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.
