Operation
REMOVING AND INSTALLING SHREDDER SCREEN
The shredder screen is factory-installed inside the
processing chamber. Vacuumed or chipped material
passes through the slots in the screen before it is
discharged. The screen produces up to an 8:1 reduction
of material.
The screen is designed for use only with dry materials.
Before processing damp materials, remove the screen
to reduce clogging and to improve air flow inside the
processing chamber. The screen can be removed and
re-installed without tools.
WARNING
Before removing or installing the shredder screen,
stop engine and make sure that all moving parts have
come to a complete stop. Disconnect the spark plug
wire and secure it away from the spark plug. Failure
to follow this instruction could result in personal
injury.
