Blade seating

Blade seating is a critical step in blade set-up that is commonly overlooked. Before installing the top blade, check that the mounting surfaces are clean. After the installation, the top blade will be seated which increases cut quality and blade life. In the first few revolutions of the top blade and bottom band, a wear pattern is established that determines how effectively the pair will run.

Step 1:

Step 2:

Turn the blade a few turns in opposite direction.Tublade seatingrn the blade in the opposite direction from that which it turns during normal operation. Continue spinning for 3 - 4 revolutions. This will properly seat the fine superfinished tip.

 

Step 3:
