1. Raise the GrindLazer to a height where the cutters
are easily accessible. Support GrindLazer with

24mm socket or a wrench. It is recommended to
use an impact wrench if available.
Cutter Head Replacement
1. Slide backing plate onto spindle shaft. Slide felt
washer onto shaft into the ring in the backing plate.

plate.
3. Slide felt washer onto the shaft into the space
between the cutter edge and the bearing edge.
4. Slide outer bearing cover onto shaft against the felt
washer.
5. Slide Belleville washer onto shaft against the outer
bearing cover.
NOTE:
The washer should bend outward.
6. Place hex nut onto shaft. Tighten so the nut is tight
