Cleaning & Maintenance - Renfert MT 2 Mode D'emploi

Various factors influence the service life
of trimmer discs. Particularly in the case
of diamond-coated discs, an adequate
water supply is very important. Overhea-
ting will result in damage to the trimmer
disc.
Never use the trimmer discs to grind
metal. Muffle rings, pins, and retention
rings, etc. can also damage trimmer
discs. Investments contain extremely ab-
rasive components that will significantly
shorten the disc's service life.
