Cleaning of Fuel System
When refueling your engine, it is important to refuel with high test fuel
(Not E85 Ethanol). Small engines will start easier, operate smoother
and will last longer with high test fuel. High test fuel will also last
longer before decomposing and clogging the carburetor. Any fuel that
sits longer 3-4 weeks is recommended to have fuel conditioner added
to ensure the fuel remains stable.

5.21 Blades / Rotor Maintenance
Your woodchipper will have 2 blades. Blades are a consumable item
that will need to be sharpened or replaced when they get dull.
Woodchipper blades can be sharpened 2-4 times depending on the
depth of each sharpen. These woodchipper blades are case
hardened and must be sharpened at the same angle, but not be
sharpened further than .125” from the original edge. Both blades
must be sharpened equal amounts to maintain blade balancing.
