UsingtheChipper Shredder V acuum
Place both hands on top of the upper handle to push
unit over yard waste. Yard waste such as leaves and
pine needles can be vacuumed up through the nozzle
for shredding. After material has been shredded by the
flail blades on the impeller assembly, it will be
discharged into catcher bag or through blower chute.
Do not attempt to shred or chip any material other than
vegetation found in a normal yard (i.e. branches,
leaves, twigs, etc.) Avoid fibrous plants such as tomato
vines until they are thoroughly dried out. Materials such
as stalks or heavy branches up to 1-1/2" in diameter
may be fed into the chipper chute.
IMPORTANT: The flail screen is located inside the
housing in the discharge area. If the flail screen
becomes clogged, remove and clean as instructed in
the Maintenance section on page 9. For best
performance, it is also important to keep the chipper
blade sharp.
WARNING:
Do not at any time make any
adjustments without first stopping the
engine and disconnecting the spark plug
wire.

adjustment lever to one of five positions, ranging from
5/8" to 4 1/8" ground clearance. Raise the nozzle height
