PX-3 PAVER EXTREME MAINTENANCE BLADE DRESSING Like most cutting instruments, a Diamond Blade performs best when it is dressed. Over time and use, diamonds on the outer edge will become smooth or “glazed” over. This will reduce grinding efficiency and may cause the blade to “wander” or bend, giving the illusion of an alignment problem. When this occurs, the blade will need to be dressed. The Diamond Blade can be dressed using the MK Dressing Stick (Part #152792) and by following the steps below. 1.

PX-3 PAVER EXTREME PARTS LIST THEORY OF DIAMOND BLADES Diamond blades do not really cut; they grind the material through friction. Diamond crystals, often visible at the leading edge and sides of the rim/segment, remove material by scratching out particles of hard, dense materials, or by knocking out larger particles of loosely bonded abrasive material. This process eventually cracks or fractures the diamond particle, breaking it down into smaller pieces.
