SAFETY INSTRUCTIONS
CUTTING BLADES
General
Cutting blades are available in two basic designs; abrasive
discs and diamond blades. Only abrasive discs and diamond
blades may be used and only within their respective application
areas.
Abrasive discs
The cutting material on abrasive discs 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. (The
term reinforced does not refer to those cutting blades that are
only reinforced around the flange).
A cutting blade’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 blade a shorter service life and
greater cutting capacity are said to make the blade ”softer”. A
blade with a longer service life and slower cutting capacity is a
blade with a ”harder” effect.
High quality cutting blades are normally more economical.
Lower quality cutting blades usually have an inferior cutting
capacity and shorter service life, which results in higher cost per
processed material.

ABRASIVE DISCS, TYPES AND USES
Use
!
WARNING!
A cutting blade may burst and cause injury to
the operator.
High speed portable tools
Our cutting blades are manufactured for high-speed, portable
power cutters. If blades from other manufacturers are used,
ensure that the blades conform to all regulations and demands
that concern this type of power cutter.
!
!
Always contact local authorities and make sure you are
following applicable directives.
WARNING!
Never use a cutting blade for any other
purpose than that it was intended for.
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.
WARNING!
Never use a cutting blade at a lower speed
rating than that of the power cutter.
