blade Sharpening

Sharpening of the shredder blade, flail blades and chipper blades
are required maintenance to be performed by a professional
service center or knowledgeable and experienced owners
only. Sharpening of the blades will keep the chipper-shredder
performing at a higher quality than with dull blades. Sharp
blades will chip or shred material faster and easier, and cause
the engine and other parts to work less. Blades are not covered
under warranty as they are a wear item, and therefore should be
sharpened regularly to keep their edge and to ensure a longer life
of the blades, other parts and engine.
1. Make sure spark plug wire is disconnected.
2. Disconnect the recoil housing on the front of the engine.
3. To get to the blades and impeller, the outer flail housing
