Sharpening Knives - Granulators with Open Cutter

Keep the complete set of knives together as one unit.

✐NOTE: To avoid unbalance, all the knives belonging to the cutter must be ground exactly the same.

Be careful when handling the knives, they are sharp and can cause personal injury.

✐NOTE: Get an experienced craftsman to sharpen the knives.

Only sharpen the marked surfaces and respect the given dimensions!

The knives must be sharpened exactly, to get the correct cutting and relief angles. Otherwise the efficiency of the granulator will be impaired.

The knife must be cooled during sharpening. The knives must not be burned or blued under any circumstances, otherwise they will loose their hardness and dura- bility.

If the knife is blued or burned, they can not be repaired by grinding down the blued or burned area. The hardened knife is then completely spoiled and has lost all its hardness and durability.

Use the Conair grinding jig SF-20 (accessory, art no. 3-030324) and a surface grinder with magnetic table. The jig gives exact correct cutting and relief angles.
