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.

!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.

!WARNING!

Never use a cutting blade at a lower speed rating than that of the power cutter.

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 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 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.
