SAFETY INSTRUCTIONS
CUTTING DISCS AND BLADES
!
General
Cutting discs and discs are available in two standard designs;
abrasive discs and diamond discs.
High speed portable tools
Cutting discs of the make Husqvarna are manufactured for
portable, high speed, power cutters. If other makes of cutting
discs are used, ensure the discs comply with all the directives
and requirements attributed to the specific type of power cutter.
WARNING!
Never exceed the maximum working speed of
a cutting disc.
Special discs
Some cutting discs are designed for stationary equipment and
for use with attachments, for example, rail cutting equipment.
These types of cutting discs must not be used on portable,
power cutters.
WARNING!
Never use a cutting disc for any other purpose
than that it was intended for.
Always contact local authorities and make sure you are
following applicable directives.
Abrasive discs
The cutting material in an abrasive disc consists of abrasive
corn that is held together by an organic bonding agent.
”Reinforced discs” are made up of a fabric or fibre base that
prevents total breakage at maximum working speed if the disc
should be cracked or damaged. (The term reinforced does not
refer to those cutting discs that are only reinforced around the
flange).
A cutting disc’s performance is determined by the type and size
of abrasive corn, and the type and hardness of the bonding
agent.
Characteristics that give the disc a shorter service life and
greater cutting capacity are said to make the disc ”softer”. A
disc with a longer service life and slower cutting capacity is a
disc with a ”harder” effect.
High quality cutting discs are normally more economical. Lower
quality cutting discs usually have an inferior cutting capacity and
shorter service life, which results in higher cost per processed
material.
