Open the lower door and uninstall the lower blade guard by loosening the guard locking knob. 3. Adjust the lower guide and thrust bearings below the table, using the similar procedure as for the upper guides.
  • Page 16 6.2.4 Guide Post Parallelism The guide post should be parallel to the blade throughout the travel of the guide post.The guide bearings will maintain the gap to the blade at any height and won’t have to be re-set each time the guide post is moved. This setting has been accurately made by the manufacturer and should not require immediate attention, but it may be checked in the future as follows: Refer to Figure 12.
