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
0,2 - 0,25 mm from the blade.
