Base Roller Rails are available on all new bricksaws.
They provide easy repair of annoying divets.
Divets are caused through the vibration of the bricksaw carriage when the bricksaw is left unattended with the engine running.
This problem applies to petrol engine bricksaws only.
To repair divets, simply turn the base roller rails over.
Base Roller Rails are not recommended for old bricksaws.
