NOTE:
The instruction for knife grinding refers to 3 different knives.
Grinding of: – rotating knives.
– rear fixed knife no. 1, front fixed knife no. 2, fourth and fifth
fixed knife.
– third fixed knife.
All knives must be ground precisely, to give the correct cutting and relief angles.
Otherwise the granulator looses its efficiency.
Be careful when you handle knives!
Knives are sharp and can cause personal injury.
Only grind the marked surfaces, and respect the specified dimensions!
NOTE:
Conair knives are made from hardened steel.
Hardened steel knives are brittle and can crack if they are dropped or are handled
carelessly.
It requires skill to grind knives, so please let a skilled, experienced crafts-
man grind the knives.
Cool the knives when you grind them
Heat is developed during grinding, so the knives must be cooled when they are
being ground. Knives which are exposed to excessive heat, are burned or blued,
loose their hardness, strength and durability.
Knives which are burned, blued, or exposed to excessive heat, can not be repaired
by grinding away the blued or burned color.
Blued or burned knives are useless.
Grinding fixture (option).
For 18 Series granulator models use the
Conair grinding fixture art.no. 3-45652.
Using the grinding fixture and a surface grinder
with magnetic table, all the knives in the granulator
can be ground with the precise, correct cutting and relief angles.
