• The spring loaded pin must be in the first hole
(closest to the end of the tube) of the hose adapter
to operate the nozzle vac.
• Place both hands on top of the upper handle and
fully lift the drive control against the upper handle to
propel the unit over yard.
• Use the speed control to choose either the high or
low speed. The speed control may be moved either
while the unit is propelling or before engaging the
wheels.
IMPORTANT:Move the speed control only when the
engine is running. Changing the speed control setting
with the engine off can damage the yard vacuum.
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.
_, WARNING:
Do not attempt to shred,
chip, or vacuum any material larger than
specified on the machine or in this
manual. Personal injury or damage to the
machine could result.
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 16. 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 engine
and disconnecting spark plug wire.
USING THEHOSE ASSEMBLY
