necessary.

SafeHandling of Gasoline:

To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.

Wash your skin and change clothes immediately.

a. Use only an approved gasoline container.
b. Never fill containers inside a vehicle or on a truck

or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle

before filling.

c. When practical, remove gas-powered equipment

from the truck or trailer and refuel it on the ground.
If this is not possible, then refuel such equipment on

a trailer with a portable container, rather than from a
gasoline dispenser nozzle.

d. Keep the nozzle in contact with the rim of the fuel

tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.

e.

Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

f.

Never fuel machine indoors.

g.

Never remove gas cap or add fuel while the engine
is hot or running. Allow engine to cool at least two

minutes before refueling.

h. Never over fill fuel tank. Fill tank to no more than 1/2

inch below bottom of filler neck to allow space for
fuel expansion.

i. Replace gasoline cap and tighten securely.

j. If gasoline is spilled, wipe it off the engine and

WARNING: The operation of any chipper shredder

can result in foreign objects being thrown into the

eyes, which can damage your eyes severely. Always
wear the safety glasses provided with this unit or

eye shields before chipping or shredding and while

performing any adjustments or repairs.

StartingEngine

IMPORTANT: Because this manual covers several different model
units, different starting instructions may apply to your particular

engine. Some engines may have a fuel petcock, some may not.
Some engines may have On/Off switches, other may not. Some
units will utilize a choke system, while others will require priming.

These factors depend on what make and model engine comes
with your particular unit. For these reasons, please refer to the
engine operator's manual for the correct starting procedure.

Bask Starting Pr0(edure:

1. 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.

2. Open fuel shut-off valve (If equipped) and make sure the
On/Off switch is in the On position (if equipped).

3. Move choke control lever to CHOKE position, if equipped.
See Fig. 5-1. If the unit has a primer, prime the motor as
instructed in the engine operator's manual.

5. Grasp starter handle and pull rope out slowly until engine
reaches start of compression cycle (rope will pull slightly
harder at this point).

NOTE:A noise will be heard when finding the start of the
compression cycle. This noise is caused by the flails and
fingers, which are part of the shredding mechanism, and it
should be expected until the impeller reaches full speed.

6. Pull rope with a rapid, continuous, full arm stroke. Keep a
firm grip on starter handle. Let rope rewind slowly.

7. Repeat the previous steps until engine starts. When engine
starts, move choke control gradually to RUN position until
the engine is running smoothly.

_ ARNING: Never run the engine indoors or in a

poorly ventilated area. Engine exhaust contains
carbon monoxide, an odorless and deadly gas.

Stopping Engine

1. Move throttle control lever to STOP position (if equipped)
or push rocker switch to OFF. See Fig. 5-2.

Loweringthe Hopper

1. With one hand grasp the handle at the top of the hopper
and lift slightly.

2. With the other hand pull out on the release rod and lower
the hopper to the ground.

Shredding

Yard waste such as leaves and pine needles can be raked up in
the hopper for shredding. After material has been processed by

the shredder blade and flails, it will be forced out of the chute
deflector, and, if attached, into a debris collection bag.

Observe the following guidelines when shredding yard debris:

Never attempt to shred material other than normal yard
debris (leaves, twigs, pine cones, etc.).

Avoid shredding fibrous plants such as tomato vines until
they are thoroughly dried out. Fresh vines do not shred
well and tend to wrap themselves around the impeller and

flails.
Place reasonable amounts of debris into the hopper at a

time. Do not overload the hopper.
Allow the material in the hopper to be drawn into the

blades and shredded before adding additional debris
to the hopper. Failure to due so may result in a clogged

hopper, clogged chute deflector or a stalled engine.
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 &

Adjustments section. For best performance, it is also
important to keep the chipper blade sharp.

Chipping

Branches up to two inches (model series 450) or three inches
(model series 460) in diameter can be fed into the chipper chute.

Observe the following guidelines when chipping branches:

Keep both hands firmly on the branch as you feed it into
the chipper chute.

Never feed more than one branch into the chipper chute at
a time.

Never feed anything other than branches (or wood) into
the chipper chute.

Apply intermittent pressure (force, in short pulses) while
feeding larger branches into the chipper chute, to avoid

bogging or stalling the engine.
IMPORTANT: Never feed branches with a diameter greater

than two (2) inches (Model Series 450) or three (3) inches
(model series 460) into the chipper chute. Doing so can

result in serious damage to your unit's chipper blades, flails
or impeller.

NOTE: For best performance, always operate the unit with
sharp chipper blades. Ira noticeable loss in performance is
encountered while chipping branches, the chipper blades
should be replaced.
