Automatic Lower Crash Protection System
Many Engine Blocks have interference in the lower area of the bores and can damage honing stones and holders. Every
time the H85A starts honing a cylinder, the machine will check bores for interference avoiding potential damage to honing
stones and holders. Variances in lower bores are common. Rottler H85A Control senses lower bore interference prior to
rotation and stroking stroking motion starting at full power, eliminating any stone or holder damage.
