IMPORTANT SAFETY INSTRUCTIONS

READ ALL INSTRUCTIONS BEFORE USING

WARNING

• To prevent personal injury or property damage, do not attempt to start engine until all assembly

steps are complete and you have read and understand the safety and operating instructions in this
manual.

• Under California law, and under laws of several other states, you are not permitted to operation

internal combustion’s engine using hydrocarbon fuels on any forest covered, brush covered, or
grass covered land, or on land with grain, hay, or other flammable agricultural crop, without an
engine spark arrester in continuous effective working order. The engine on your power equipment,
like most outdoor power equipment, is an internal combustion engine that burns gasoline, a
hydrocarbon fuel. Therefore, your power equipment must be quipped with a spark arrester muffler
in continuous effective working order. The spark arrester must be attached to the engine exhaust
system in such a manner that flames or heat from the system will not ignite flammable material.
Failure of the owner/operator of the equipment to comply with this regulation is a misdemeanor
under California law, and may also be a violation of other state and/or federal regulations, laws,
ordinances, or codes. Contact your local fire marshal or forest service for specific information
about what regulations apply in your area.

• Wear approved safety glasses when operating this equipment. The operation of any powered

machine can result in foreign objects being thrown by high-speed rotating parts.

• Wear work gloves, sturdy footwear, and hearing protection when operating this equipment.

• Remove hearing protection and watch for traffic when operating near, or when crossing roadways.

• Before inspecting or servicing any part of equipment, shut off engine, disconnect spark plug wire

from spark plug, and make sure that all moving parts have come to a complete stop. Be aware that
rotating blades slow down gradually after engine is shut off.

• Exercise extreme caution on slopes and avoid excessively steep slopes.

• Never leave equipment unattended when engine is running. Shut off engine and disconnect spark

plug wire from spark plug before leaving equipment. Turn off fuel shut-off if equipped.

• Do not vacuum any burning or smoldering materials such as cigars, cigarettes, ashes, or cinders.

• Do not run engine in an enclosed area. Engine exhaust contains carbon monoxide gas, a deadly

poison that is odorless, colorless, and tasteless.

• Do not operate this equipment near buildings, windows, or air conditioners.

• Do not allow hands or any other part of the body or clothing inside the vacuum inlet.

• Do not start engine or operate this equipment with any safety guards or housing removed.

• Before removing or installing collection bag, shut off engine, disconnect spark plug wire from spark

plug, and allow all moving parts to come to a complete stop.

• Empty the collection bag after each use. Decomposing debris could generate enough heat to

catch fire. Before emptying the collection bag, shut off engine, disconnect spark plug and allow all
moving parts to come to a complete stop.

• If equipment jams or becomes clogged, immediately shut off engine, disconnect spark plug and

allow all moving parts to come to a complete stop. Use only a wooden stick to clear away debris.

DANGER

Gasoline is highly flammable and its vapors are explosive. To prevent personal injury or property
damage:

• Do not add fuel if engine is running or still hot from recent operation. Allow engine to cool for at least

three minutes.

• Do not fill fuel tank indoors. After filling, wipe up any spills and move away from gasoline fumes

before starting engine.

• Do not allow open flame, matches, or smoking in area.

• Fill fuel tank with fresh, clean unleaded regular automotive gasoline, (leaded regular and unleaded

or leaded premium grades of gasoline are acceptable substitutes).

• Do not mix oil with gasoline.

• Clean the area around the fuel fill cap and remove the cap from the fuel tank. Insert a clean funnel

into the fuel tank.

• Fill the tank to 1/2 inch below the bottom of the filter neck to provide space for any fuel expansion.

SAFETY INTERLOCK SYSTEM

Your machine is equipped with a safety interlock system which prevents the engine from starting
unless a vacuuming attachment and the fan cover are installed.

The system also stops the engine if the operator attempts to remove an attachment or the fan cover
while the engine is running.

If the safety interlock system fails, shut off the engine and do not operate the machine until the system
has been repaired. Contact your local servicing dealer or the factory for assistance.

Testing the Safety Interlock System

The following test should be performed prior to each day’s use of your machine.

1. Start the engine.

2. Disconnect the three-pronged connector (on end of cord extending from attachment) - See fig. 1.

• If the engine begins to stall, the system is working properly. Reconnect the three-pronged connec-

tor by gently but firmly pushing the connector onto the switch. The two longer prongs fit on either
side of the switch button housing; the shorter prong depresses the switch button.

• If the engine does not begin to stall, it means that the system is not functioning properly (Briggs &

Stratton.) Stop the engine by moving the Engine Throttle Control (on right side handlebar) to the
STOP position. (Honda) Turn switch on side of engine to off position. Refer to Figure 1, Page 19.
Disconnect the spark plug wire from the spark plug. Do not operate the machine until the safety
interlock system has been inspected and repaired.

WARNING

To avoid personal injury or property damage, do not operate machine unless
safety interlock system is functioning properly.

OPERATION

VACUUMING ATTACHMENTS AND SHREDDER SCREENS IDENTIFICATION

To install shredder screen, remove
faceplate (ref. Figure 1) by removing (4)
knobs on front of machine. Insert shredder
screen as shown and reinstall knobs.

Shredder Screens

The shredder screen (see Figure

2) fits inside the chamber,
completely surrounding the vacuum
fan blades. Material that has been
chipped or vacuumed must pass
through the slots in the screen
before it is discharged. The size of
the slots in the screen determine
how finely materials are shredded.
The standard, 1 1/8" slotted screen
supplied with all machines will
produce up to an 8:1 reduction of
material. The optional, 3/4" slotted
screen will produce more finely
shredded material at a ratio of up
to 11:1.

Vacuum Inlet/Chipper Adapter

For vacuuming, install vacuum inlet
as shown in Figure 3, Page 13. For
chipping and/or shredding without the
vacuum inlet assembly, use chipper
adapter Figure 4 as shown on Page

13.

12

Vacuum Attachment

The vacuum inlet assembly can be adjusted
to varying heights by raising or lowering the
two front casters. Then the front edge of the
housing should be about 2" off the ground.

Chipper Adapter

The chipper adapter is used instead of the
vacuum inlet assembly when large volumes
of material are being chipped. The use of this
adapter aids in the self-feeding
characteristics of the chipper shoot.

WARNING: When operating without the collec-

tion bag, or when the collection bag flap is open,

be aware that the shredded material will scatter

over a fairly large area. Check your surround-

ings before beginning operation.

Operation

Tips for Using the Chipper

Your experience is vitally important to
successful chipping. We suggest that you start out
slowly by feeding limited quantities of material into
the chipper. Bulk and lengths can be gradually
increased if the Material is being processed
without difficulty.

The chipper is designed to be self-feeding.
However, the physical characteristics of materials
vary and will therefore require different operating
techniques, as explained in the chipper operating
instructions.

Always avoid overfeeding materials into
the chute. Overfeeding causes the engine to labor
and slow down which reduces chipper
performance. Best results are obtained when the
engine is running at or near full speed.

Whenever possible, process branches
while they are still fresh - green wood chips more
easily than dry wood.

Extremely crooked branches, or bunchy
material such as pine boughs should be cut or
trimmed so that they will feed easily into the
chipper chute.

Alternating dry materials with wet or green
materials helps prevent clogging of the shredder
screen.

Keep the chipper cutting blade sharp.
Severe vibration or slow progress when you feed
material into the machine is a sign that the blade
may be dull. (Extremely hard wood, stringy wood,
or wood containing knots can be difficult to chip
even with a freshly sharpened blade. Try
processing some softer wood. If the chipping
performance is still poor then the blade is probably
dull.)

Certain types of thin, flexible shoots may
slip past the chipper blade without being cut. To
avoid clogging the collection bag or discharge
chute, empty the collection bag more frequently
when processing shoots. The shoots can be easily
separated from the wood chips, and discarded.

Positioning the Chute Extension for
Light or Heavy-Duty Chipping

A chute extension (shown in Figure 1) is
attached to the top of the chipper chute.
The chute extension is hinged to allow
folding for compact storage and easier
maneuverability of the machine.

In the folded position, the chute extension
has an opening that permit light brush and
thin branches to be fed into the
chipper chute. In the upright position, the
chute extension accepts larger, bulkier
material. Refer to Figure 1 for instruction on
how to unfold and fold the chute extension.

IMPORTANT: Be sure to lock the chute
extension with the latch when the chute
extension is in the upright, unfolded
position.

Operation

Chipper Operating Instructions

1. Make sure that a vacuuming attachment and the collection bag are properly installed. The vacuum inlet cap (page
13, figure 4) is recommended for use when performing large-scale chipping projects.

2. Make sure you are wearing safety goggles, work gloves, sturdy footwear, and hearing protection.

3. Start the engine. The chipper blade (and the vacuuming attachment) are now in full operation.

4. Park the machine on level ground. Place the GEAR SHIFT LEVER in neutral and set parking brake.

5. To feed material into the chipper chute, stand a foot or two away from either side of the chipper chute. Do not stand
near the hot engine exhaust or muffler.

• Do not point your arms into the chute keep them perpendicular (a 90° angle) to the branch.

• Keep your face and body safely away from the chipper chute and branches.

• Drop light brush, stalks, vines, or branches up to about 2" in diameter into the chute and the self-feeding action

will pull them downward. If necessary, help guide the material downward until your hands begin to come near the
top of the chute and then let go! NEVER PUT YOUR HANDS INSIDE THE CHIPPER CHUTE! If necessary, push
the material further downward with a long stick or branch.

• Larger branches, particularly hard wood may require that you control the rate of feed. Hold one end of the branch

firmly with one or both hands and feed the branch slowly into the chipper chute (rotating the branch may help it
to feed more easily). If the engine labors, pull the branch upward to allow the engine to regain speed. Continue
to alternately feed and retract the branch until your hands begin to come near the top of the chute and then let
go! NEVER PUT HANDS INSIDE THE CHIPPER CHUTE!

• Do not reach into the chipper chute to retrieve material that is below the top of the chute. Shut off the engine,

disconnect the spark plug wire, and wait for all moving parts to stop before attempting to retrieve any materials.

6. If a piece of wood is too large or hard to be processed, you should put it aside for firewood.

7. If a branch causes the engine to stall, remove the branch and restart the engine. Stalling does not harm the engine.

8. Empty the collection bag frequently when using the chipper.

9. To stop the engine, Briggs & Stratton equipment, move the Engine Throttle Control to the STOP position. For Honda
equipment, reduce engine speed to slow, turn engine STOP control to off, on side of engine. Remove any hearing
protection and listen for all moving parts to come to a complete stop.

Clearing the Machine of Clogs and Jams

A clog or jam in the machine can cause the vacuuming and chipping operations to decrease or even stop completely.
If this occurs, take the following steps:

1. STOP THE ENGINE IMMEDIATELY and disconnect the spark plug wire from the spark plug. Wait for all moving
parts to come to a complete stop.

2. Check (and clean, if necessary) the following areas in this order:

• Check that the collection bag is not overfilled. To remove and empty bag, see Page 9.

• While the bag is removed, check that the discharge deflector is not clogged or jammed. Use a stick to clear

away any debris.

• Check that the vacuuming attachment is not clogged or jammed. Remove the attachment and thoroughly clean

the opening. While the attachment is removed, check the inlet opening to the machine. Use a stick to clear
away any debris.

• Check that the shredder screen (if installed) is not clogged.

TRANSPORT DRIVE/PARKING BRAKE

Transport Drive

• Operate the machine in a large, level, open area until you are familiar with its operation. Begin with

speed No. 1 and gradually work up to speed No. 4. (Figure 1)

• To avoid damaging the transmission, always release the Clutch Lever (Figure 2) and wait for the

wheels to stop before shifting gears.

• Forward momentum may cause the machine to gradually coast to a stop after the Wheel Drive is

released (especially when in 3rd or 4th gear). Allow for this coasting distance when stopping the
machine.

• Engage the Clutch Lever slowly when starting off in 3rd or 4th gear. The machine may hesitate

briefly before the wheels begin turning.

• Shift to a lower forward gear if the wheel lose traction when going up a slope (always avoid exces-

sively steep slopes). Before shifting, turn the machine sideways on the slope to prevent rolling of
the machine and to relieve strain on the transaxle.

• Never force the shift lever as damage may result. If shifting is difficult, it may be necessary to

manually move the machine a few inches forward or backward while moving the shift lever.

Parking Brake

Located on left side of machine. Lower
