Blade Safety Brochure



There are many reasons a segment may chip or detach during operation. These are avoidable if good housekeeping and safety is practiced, one of the more common is “dirty clamp plates” and this is the focus of this circular. Segments can become chipped or may detach in the event of the blade not being secured correctly causing the blade to flutter and chip. This is more common in blades which carry a higher segment, as these are more vulnerable than a standard segment. The most common cause of this is dirty clamp plates. Clamp plates may have grit or remnants of previous discs blotter glue which prevents the clamp plates adhering to the blade blank firmly. This causes the blade to flutter and in turn chips the segment or in some cases segment loss.

Granites and other stone types with large pieces of natural elements offer less tolerances than cementitiuos material when cutting. This coupled with poor cutting practices and habits from the saw operative exacerbate the chances of segment damage. Typical site environments cannot avoid the transfer of sand or other dusty gritty particles to material, plant and machinery; open windy conditions can blow dusty particles around freely. But with vigilance and good practice before any incidents this can be addressed and avoided. As petrol saws seem to be the standard go-to saw for most site cutting applications due to their versatility, it’s important to carry out routine regular checks before and during cutting and especially when mounting the blade.

This is most common on petrol disc cutters due to the multiple variables and vibration properties which cannot be avoided with these saws.
