SECTION 4: OPERATING YOUR CHIPPER SHREDDER VACUUM
•
Read, understand, and follow all instructions and
warnings on the machine and in this manual before
operating. A pair of safety glasses has been
provided with this equipment.
•
Repeat until engine cranks. When engine starts,
move choke control (if equipped) gradually to RUN
position.
NOTE: See your engine manual packed with your unit
for more detailed instructions.
WARNING: Always wear safety glasses
during operation or while performing any
adjustments or repairs. Thrown objects which
ricochet can cause serious injury to the eyes.
To Empty Bag
•
Open the large zipper in the rear of the bag to
empty the contents. Be certain the zipper is closed
completely when operating the unit.
Gas & Oil Fill-Up
•
If bag is removed for any reason, follow instructions
for attaching the bag in the ASSEMBLY section.
Service the engine with gasoline and oil as instructed in
the engine manual. Read instructions carefully.
WARNING: Use extreme care when
handling gasoline. Gasoline is extremely
flammable and the vapors are explosive. Never
fuel machine indoors or while the engine is hot
or running. Extinguish cigarettes, cigars, pipes,
and other sources of ignition.
To Engage Drive
•
•
•
•
To engage the wheel drive, hold the drive clutch
control against the upper handle.
Release the drive clutch control to stop the rear
wheels from driving.
Release the drive clutch control to slow down when
negotiating an obstacle, making a turn, or stopping.
Engage control slowly to prevent the front wheels
from lifting up.
Starting Engine
WARNING: Keep bystanders, helpers, pets,
and children at least 75 feet from the machine
before starting and while operating. Do not
operate this machine unless the discharge
chute and bag have been properly installed
and secured to the machine.
Using the Chipper Shredder Vacuum
•
Place both hands on top of 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.
•
Attach spark plug wire to spark plug. Make certain
the metal cap on the end of the spark plug is
fastened securely over metal tip on the spark plug.
Make certain drive clutch control is in the
disengaged (released) position.
Engines with choke lever: Move choke lever on
engine to CHOKE position. (A warm engine may
not require choking).
Engines with primer: Prime engine as instructed
in the engine manual.
Move engine throttle control lever to FAST or
START position.
Place one foot on the left rear wheel to prevent the
unit from skidding while starting.
Grasp starter handle and pull rope out slowly until
engine reaches start of compression cycle (rope
will pull slightly harder at this point).
•
After material has been shredded by the blades on
the impeller assembly, it will be discharged into
catcher bag. 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 3” 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. For best performance, it is
also important to keep the chipper blade sharp.
NOTE: A noise will be heard at the start of the
compression cycle, which will continue to be heard till
the impeller reaches full speed.
Tire Pressure (Pneumatic tires only)
•
Keeping a firm grip on the starter handle, pull rope
with a rapid, continuous, full arm stroke. Let the
rope rewind slowly.
Maximum tire pressure under any circumstance is 30
psi. Equal tire pressure should be maintained at all
times.

a. the chipper shredder vacuum moves forward
with the drive clutch control disengaged,
b. it does not self-propel with the drive clutch
control engaged, or
c. drive belt is slipping (unit hesitates while
engine maintains the same speed).
•
Lift and place pins in the larger holes for locked or
straight ahead operation. See Figure 8.
a. Place pins in smaller holes to allow casters to
rotate freely.
b. Lock wheels in straight position when
operating on slopes.

•
Use the adjustment wheel located in the clutch
control housing to tighten or loosen the clutch
cable.
In addition, the adjustment wheel may also be used
to determine the position in which the drive clutch
control is engaged. If it is more comfortable to have
the drive engaged with the lever further away from
the handle, tighten the clutch cable. See Figure 10.
