Adjusting Blade

Guides

Each blade guide assembly consists of Guide Blocks and a Support Bearing.

The blade guides keep the blade stable dur- ing operation, so make sure they are properly adjusted before starting the bandsaw.

These instructions are hazardous if done while the machine is connect- ed to power. Disconnect power during this entire procedure!

Guide Blocks

Each guide block consists of an upper and lower ceramic block that stabilizes the blade from up/ down movement during operation.

The lower block is designed to remain in a fixed position, and the upper block is designed to be adjusted during each blade change. When the machine is new, the lower block is set at the factory and should not need to be adjusted (see Section 8: Service Adjustments for more infor- mation about the lower guide). The upper block, however, should be adjusted every time you install a new blade or re-install an old blade.
