Notes

*Blade Centre Spigot / Hub

Blade centre hubs are removable and can be replaced to provide for different blade centre holes.
Special blade centre disks can be ordered to accommodate other blade dimensions.
Changing the blade centring disk does not effect the location and dimensions of the blade fixing screws.

** Blade Screws

Use only high-tensile (10.9 or 12.9) screws for attaching the blade

Unused screw holes should be plugged with grub screws

For flush cutting, countersink screws are required and the countersinks in the blade must be sufficiently deep to avoid damage to the exposed face of the screws.
If the blade is too thin to accomodate the head of the screw, spacer plates are available and must be used.
