5.2 Blade Guides
1. Check the rollers for performance and wear every blade change. Make sure the rollers are clean and
spinning freely. If not, rebuild them. Replace any rollers which have worn smooth or have become
cone shaped.

2. Inspect the blocks at every blade change for damage or wear.
As the blocks wear, the front inside corner will wear more than the body of the block. When the
corner wears far enough, sawing performance will be affected even if the body of the block is
adjusted properly to the blade. At this point, the block should be replaced. If you have access to the
appropriate equipment, you can grind or mill the blocks to a new flat surface and reuse them. It is
recommended you develop a routine schedule for replacing the blade guide blocks based on your
sawing conditions and experience.
3. Check the ceramic inserts are properly spaced from the bottom of the blade every 25 hours of
operation. As the rollers wear, the gap between the blade and inserts will become larger. Use the
provided shim or a feeler gauge to check the inserts are adjusted 0.3-0.5 mm from the blade.
See Figure 5-1. To adjust the disks up, loosen the bottom guide disk mounting bolt and clamp bolt.
