BLADE MAINTENANCE

1.  AutoGuide - shim to tolerance and replace when shims exceed 0.100”.

2.  Upper and Lower Cutting Blades - identical, non-rotating blades, grind 

rolled edges as needed, replace when worn.

3.  Guide Blades - non-rotating blades designed to prevent jaw wear. 

These are not the primary blades for cutting rail.

4.  Jaw Hard-surfacing - build-up and hard-surface as needed.

5.  Jaw Armor

™

 - Build-up or replace as wear out.

Blade and blade seat maintenance greatly affects performance. To maximize cutting performance 

and optimize the life of replaceable parts, follow this specific sequence of checks, adjustments 

and maintenance.
