MAINTENANCE AND STORAGE
Blade Sharpening Cont’d. 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 assembly (#40) must be removed. The
steps in the flail housing and impeller cleaning
section should be followed to remove it and the
shredder screen (#60). (A)
