IMPORTANT: The vacuum bag may have an air
escape located on the upper left hand side. See figure

operated in wet, sandy or muddy conditions.
The bag may be emptied using the large zipper as

TO ENGAGE DRIVE
iMPORTANT: Always release the drive ciutch han-
die before moving the shift iever.
With the engine running near top speed, move shift
lever into one of the six FORWARD positions or two
REVERSE positions. Select a speed appropriate for
the conditions that exist. Use the slower speeds until
you are familiar with the operation of the chipper-
vacuum.
To engage the wheel drive, hold the drive clutch
handle against the chipper-vacuum handle. Releasing
the drive clutch handle stops the wheels from driving.
Release the drive clutch handle to slow down when
negotiating an obstacle, making a turn or stopping.
Engage slowly to prevent front wheels from lifting up.
HOW TO USE THE CHIPPER
Do not attempt to shred or chip any material other
than vegetation found in a normal yard (i.e., branches,
leaves, twigs, etc.). Material such as stalks or heavy
branches
up to 3" in diameter may be fed into the
chipper chute. See figure 10.
WARNING: Material up to a maximum of
3" in diameter may be fed into the
chipper chute. Do not attempt to shred or
chip any material larger than 3" in diame­
ter. Personal injury or damage to the
machine could result. A

IMPORTANT: There is a flail screen 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 important to keep the
chipper blades sharp. Refer to Maintenance section,
page 9. If the composition of the material being dis­
charged changes (becomes stringy, etc.) or if the rate
at which the material is discharged slows down
considerably, it is iikely that the chipper blades are
dull and need to be sharpened or replaced.
ADJUSTMENTS
A WARNING: Do not at any time make any
adjustment to the unit without first stop­
ping engine and disconnecting spark
plug wire.
HEIGHT ADJUSTMENT
The height adjustment knob is located on the right
hand side of the chipper-vacuum. See figure 11. Turn
the knob clockwise to raise the nozzle. Turn the knob
counterclockwise to lower. (Be careful not to turn
knob too far—rod could come out of ferrule.)
