Sharpen Knives—450M Only (If Equipped)

E77215-UN-30SEP14

Knives can be sharp. Prevent personal injury by wearing suitable gloves when handling knives.

Protect eyes. Always wear appropriate eye protection when sharpening knives. Flying metal debris and sparks can cause serious injury.

Sharpen knives every 10 hours of operation. Depending on crop conditions, a more frequent sharpening schedule is necessary.

Avoid metal from getting overheated during sharpening. To avoid overheating cutting edge, keep flap wheel moving along the edge of knife and take small amounts of material in each pass. If steel is blued, it decreases integrity of blade and allowing the cutting edge to wear quickly.

A flap wheel (A) is recommended for sharpening knives. Use 60 grit or similar.

Always keep cutting knives sharp. Sharp knives save power and provide higher capacity.
