Guide Post

The guide post assembly is used for two purpos- es: 1) To properly position the blade guard to pro- tect the operator from the exposed blade between the workpiece and the upper wheel housing, and

2)to position the upper blade guides close to the workpiece for blade support.

In order to cut accurately and safely, position the bottom of the upper blade guides approximately

14" above the workpiece—this positioning pro- vides the greatest blade support and minimizes the amount of blade exposed to the operator dur- ing operation.

To properly position the guide post:

1.DISCONNECT BANDSAW FROM POWER!
