DESCRIPTION
General
The shredding chamber is designed to shred materials
that have been vacuumed directly into the unit through
the extra-wide vacuum intake nozzle or through the flexi-
ble vacuum hose, eliminating the need to manually load
or feed material into the shredder.
Selective vacuum-shredding can be performed with the
optional 20 foot long, large-diameter, quick-connect hose
while the unit is stationary, permitting
precisely-
controlled vacuuming of areas such as flower or shrub
beds, or other confined or landscaped areas.
Large yard, garden, or other open, flat surface areas
can be cleaned up quickly and efficiently using the
Chipper Vacuum’s self-propelled feature, which permits
vacuuming of materials while the unit propels itself.
Shredding Action
Material is drawn into the shredding chamber by the
vacuum action of the spinning rotor, and is pulled into
the path of patented shredding hammers that are rotat-
ing at the same high speed as the rotor. The hammers
cut and grind the material into progressively smaller
pieces, and the flow of air then conveys the fully
shred-
ded,reduced waste into the discharge bag.
Vacuum Action
In addition to the shredding hammers and chipping
knives, the rotor has fan blades integrated into its
design. When the rotor is spinning, a constant, powerful
vacuum action is created, which aggressively pulls
waste into the shredder chamber for shredding.
These spinning fan blades also create a blowing force
that ejects the shredded or chipped material out of the
discharge chute and into the discharge bag, making
room for more material to be pulled in and processed.
Vacuum/Shredding
l Vacuum/Shredding can be performed in confined
areas using the vacuum hose attachment, or on
large, flat areas using the
3-speed power drive and
extra-wide vacuum intake nozzle.
l Areas containing rocks, gravel, or other hard materi-
als should be avoided, as these types of materials
will damage the shredding hammers or reduce their
service life. Use of the unit to vacuum non-organic
materials will void the product warranty.
l Areas to be vacuumed should be inspected for
rocks, gravel, and other debris before use. All mate-
rials and other debris that could damage the shred-
ding hammers should be removed and properly dis-
posed of before starting the unit.
l Se particularly watchful for small, sharp objects such
as old nails, pieces of glass, and small metal objects
such as cans, can lids, bottle tops, etc.
l Review all operating safety instructions in this manu-
al before proceeding.
l Determine where the discharge bag will be emptied,
and if possible, plan a vacuum path that will allow
you to access this area easily while vacuuming.
Chipper Operation
The chipper is designed to handle tree limbs and
branches up to 2-l/2” in diameter on 5 HP models, and
up to 3” diameter on 13 HP models. The unit can also
process tough organic matter such as corn stalks and
berry canes.
Chipping operations should be performed while the unit
is stationary, and positioned so that the operator has
firm footing and easy access to the chipper cone area.
Tree limbs and branches should be inserted “butt end”
first into the chipper cone, and are fed into the chipper
block. The sharp cutting edges and angle of the blades
actually pull the tree limbs and branches into the chipper
block, cutting the material into small chips.
The chips of material then pass through a slot in the
rotor behind the chipper knives, where air flow conveys
them through the fan chamber and into the discharge
bag.
Blower Operation
The vacuum force makes it possible to use the unit as a
large-area, self-driven blower for clean-up of grass clip-
pings or other debris that you may not want to collect for
disposal or recycling.
Using the Chipper Vacuum in this mode requires the
removal of the discharge bag, and the attachment of the
optional deflector elbow. The deflector elbow is needed
to direct the powerful exhaust stream to either side of
the unit.
When used in this manner, the operator walks behind
the unit, allowing the discharge deflector elbow to blow
the lightweight debris toward an area where it can be
easily gathered later for disposal, or, as in the case of
grass clippings or other organic matter, be allowed to
decompose naturally as an added nutrient for the soil.

provided to help you understand the hazard levels associated with each signal word used in this manual.
e
The signal word “DANGER” is used when a serious
injury or fatality will result if the safety instructions
that follow this signal word are not obeyed.
A WARNING
The signal word “WARNING” is used when a seri-
ous injury or fatality could result if the safety
instructions that follow this signal word are not
obeyed.
A CAUTION
The signal word “CAUTION” is used when person-
al injury, or property or equipment damage could
result if the safety instructions that follow this sig-
nal word are not obeyed.
A DANGER
You must read and understand this manual and all
safety instructions and labeling completely, before
attempting to assemble, set-up, transport, operate,
service, or install any options or accessories on
this unit.
This Chipper Vacuum is a powerful machine
designed for chipping of tree limbs and branches
up to 2 l/2” in diameter (3” on 8 HP models), and is
capable of amputating or causing serious injury to
fingers, hands, feet, and other extremities if acci-
dental contact with rotating chipper or shredder
blades should occur.
Always keep hands, feet, and other extremities out
of the chipper cone and vacuum intake areas, and
never wear loose fitting clothing or jewelry that
could get caught on tree limbs or branches, and
pull your hands, or other body parts into the rotat-
ing chipper blades.
GENERAL
Safe operation of the Chipper Vacuum requires that all
operating and safety instructions be obeyed by everyone
who uses, services, or otherwise handles the unit.
l Inspect the chipper cone for any debris, or other
BEFORE START-UP
material that may have fallen in during unpacking
and assembly. Always disconnect the spark plug
wire trom me spark plug betOre attempting to remove
any objects from the chipper cone.
l Never fill the fuel tank indoors! Gasoline vapors are
explosive, and can easily travel unnoticed to sources
of ignition, such as pilot lights or open flames on
water heaters, furnaces, stoves, dryers or sparks
from electric motors and other electrical appliances,
or smoking materials. Contact with these or any
other ignition sources will cause an explosion or fire,
serious personal injury, and damage to property and
equipment.
Although the instructions and warnings appearing in
this manual cover most normal operating conditions,
everyone using the Chipper Vacuum must also always
follow safe work practices while operating, servicing, or
handling the Chipper Vacuum unit under any conditions
not specifically covered in this manual.
The primary operator of the Chipper Vacuum must
always be alert for the presence of bystanders, who are
likely to be unaware of the operating and safety require-
ments necessary for safe operation. It is the operator’s
responsibility to prevent bystanders from being exposed
to potential hazards whenever the Chipper Vacuum is
being used.
If you do not understand any portion of these safety
instructions, or any other
part of the instructions in this
manual, contact your local factory-authorized dealer for
help, or request factory assistance by calling: Customer
Service Department

on a firm, level, earthen or grassy area where the
unit will be stable and will stay in position. Never
attempt to operate the unit on a slope greater than
20 degrees, or on wet or slippery surfaces where
you or someone else could slip and fall toward the
chipper cone opening.
l Never operate the unit on rocky, gravel, or
stone-
covered surfaces, as this material could be sucked in
to the shredder housing through the vacuum intake
openings and cause damage to the shredder.
l This equipment shall not be operated in the vicinity
of bystanders. Never operate the unit where children,
pets, or others who may be unaware of the potential
hazards associated with chipping, shredding, or vac-
uuming operations could enter the area unexpectedly
and be exposed to these hazards.
l Never use the optional hose kit to vacuum up rocky,
gravel, or stone-covered surfaces,, as this material
will cause damage to the shredderand other internal
components.
l Never operate in an area where sparks from the
muffler could ignite surrounding dry brush or other
flammable materials. See following Fire Hazard
Warning!
l Wear hearing protection when the Chipper Vacuum
is to be used for prolonged periods of time, or when-
ever noise reaches an uncomfortable level.
A CAUTION
SPARK/FIRE HAZARD
GAS ENGINES MAY REQUIRE A SPARK
ARRESTER FOR SAFE OPERATION
If the engine on this unit is not equipped with a
spark arrester and is to be used on any forest,
brush, or grass-covered unimproved land, a spark
arrester must be added to the muffler before using
the engine on such land. The arrester must be
maintained in effective working order by the opera-
tor. In the State of California, the above is required
by law (Section 4442 of the California Public
Resources Code.) Other states may have similar
laws. Federal laws apply on federal lands. See your
authorized engine service center for muffler spark
arrester options.
SAFE WEARING APPAREL
l Always wear safety goggles to protect your eyes
from flying debris when operating the Chipper
Vacuum. One pair of safety goggles has been pro-
vided with the unit for your immediate use. All oth-
ers in and around the immediate area must also
wear approved safety glasses to protect their eyes
from flying debris.
l Always wear properly-fitted leather work gloves to
protect your hands from cuts and scratches caused
by tree limbs and branches. Never wear gloves with
pull-ties or straps, as these straps could get entan-
gled with branches and draw your hands into the
chipper cone cutting areas.
l Never wear loose-fitting clothing, hanging jewelry,
ties, scarves, or other items that could get caught on
tree limbs or branches, and draw body parts into the
cutting areas of the chipper cone.
l Always tie up long hair and prevent it from hanging
down, where it could become tangled in branches or
get caught in rotating parts and pull you into the cut-
ting areas.
l Even if you are wearing heavy-duty leather work
gloves, never, ever place your hands in the chipper
cone while the unit is running. If you must reach in
to clear a jam or free up branches, shut the unit off,
allow the rotor to come to a complete stop, discon-
nect the spark plug wire at the spark plug, and care-
fully remove or clear the jammed material.
OPERATING SAFETY

al for anv exceptions.
* If you are not using the discharge bag to collect
chipped debris, always direct the debris flow away
from yourself and others, and always stay clear of
the discharge area to avoid being struck by ricochets
or material being ejected from the machine.
l Never force material as it is being fed into the
machine, as this may result in a sudden kickback of
the material with sufficient force to injure you or other
bystanders.
l Never allow material to build up around the engine
during Chipper Vacuum operation. This could result
in a fire, or overheating of the engine.
l When using the Chipper Vacuum as a walk-behind,
large-area blower, always make sure the area to be
cleared of debris is free of gravel, stones, and other
hard debris that could be propelled with great force
by the powerful blowing action possible with this unit.
l Never continue to operate the machine if it starts
making unusual noise or vibration. Shut the engine
off immediately, allow the rotor to stop, disconnect
the spark plug wire from the spark plug, and do the

CONTROLS
A. Choke
The choke controls the fuel to air ratio, and helps make
cold starts easier by providing a rich, easily-ignited fuel
mixture.
B. Throttle
The throttle controls engine speed, and allows you to
conserve fuel by powering down during idle periods, or
to achieve optimal chipping/shredding/vacuuming power
by running the engine at full speed.
C. Vacuum Nozzle Variable Suction ControW
The vacuum nozzle Variable Suction Controlru is direct-
ly above and behind the vacuum nozzle, and has four
quick-set opening settings for variable nozzle suction
control:
l closed (for vacuuming with the optional hose
attachment)
l 113 open,
* 213 open
l full open.
Smaller nozzle openings provide the necessary vacuum
force for smaller debris, while a larger opening provides
the suction necessary for larger debris like large leaves.
D. Vacuum Nozzle Height Control
The vacuum nozzle height control lever is located at the
rear frame in front of the discharge bag. Three height
settings are available: Low, Medium, and High.
The low setting is suitable for smooth, hard surfaces,
while the medium and high settings are used for differ-
ent terrain conditions. Settings are easily changed by
simply positioning the control lever into one of three dif-
ferent slots.
The height adjustment control may be fine-tuned by
means of an rod adjustment that permits precise posi-
tion control for vacuuming of smooth surfaces. See the
adjustment procedure in the TROUBLESHOOTING
&
REPAIR section.
Operating Controls Locations (5 HP model shown)
E. Drive Speed Control
The Chipper Vacuum is self-propelled, and features
three forward speeds to help match vacuuming action to
surface conditions The drive speed control lever is
mounted on the handle within easy reach of the opera-
tor, permitting quick changes in travel speed. This fea-
ture allows you to rapidly adjust to changing conditions.
F. Power Drive Bail Lever
The power drive bail lever operates the clutch, the
mechanism that transfers power from the drive shaft to
the transmission.
Pulling the bail lever down against the Chipper Vacuum
handle engages the transmission, which drives the unit
forward for vacuum/shredding or moving the unit around
your yard and garden.
Releasing the lever disengages the transmission, stop-
ping the power drive motion, and allowing the unit to
come to a stop to make adjustments, empty the bag, or
perform chipping or hose vacuuming operations.

SITE LOCATION
1. Select an area that will provide stable footing for
both the Chipper Vacuum and the operator. Do not
operate on wet, slippery surfaces, or in areas with
heavy pedestrian traffic that may distract you from
alert operation of the unit.
2. Locate the Chipper Vacuum near the waste materials
to be chipped to reduce unnecessary lifting and
carrying.
3. Trim and stack the materials to be chipped for more
efficient and safe operation of the Chipper Vacuum.
4. Provide sufficient room for maneuvering around the
Chipper Vacuum. Never set up the work area so that
operators must over-reach or have to step over
materials to be processed.
5. Review all operating safety instructions before
proceeding.
6. Determine whether you wish to use the discharge
bag to collect the chipped material, or the discharge
deflector elbow to direct the chipper discharge to a
safe area.
7. The optional discharge deflector elbow should only
be used when the unit is positioned over a sofi
surface such as soft dirt or grass, and should always
be directed to the side and away from the operator.
8. If the discharge bag is to be used, be sure to allow

2. Inspect the chipper cone and make sure that it is
firmly attached to the shredder housing.
3. Check all parts to ensure that they are properly
attached and that all fasteners are properly tight-
ened.
4. If a discharge bag is not going to be used to accu-
mulate waste material, make sure the discharge
deflector elbow is directed away from the operator,
and that the area selected for accumulation of
chipped or shredded material will not cause ejected
material to be deflected toward the operator or
bystanders.
5. If a discharge bag is being used, make sure it is
attached to the discharge chute securely, and is
correctly supported by using all four support straps.
6. Open the Variable Suction ControlrM intake flap on
the nozzle, and check to make sure no unwanted
debris or other objects are stuck in the nozzle.
7. Fill the fuel tank to a level no closer than
l/2” from
the bottom of the filler neck. Obey all safety precau-
tions while handling and fueling the unit. Use regular,
unleaded gas only.

START-UP
The controls required to start the Chipper Vacuum are
located on the engine, and are marked “Choke” and
“Throttle” (Figure 1). A more detailed description of
engine operation and all related precautions and proce-
dures can be found in the engine manufacturer’s manual
supplied with each Chipper Vacuum.

Operation
Starting The Engine - Manual Start Units
1. Move choke lever to full choke position.
2. Move throttle lever to “fast”.
3. Place foot on front wheel to hold unit firmly in place,
and adopt a stable stance.
4. Pull starting rope out slowly one time and allow to
return normally.
5. Pull starting rope out with a steady pull, and allow
rope to return normally.
6. When engine starts, gradually move choke lever to
“no choke” position.
7. Maintain throttle speed at ‘fast” for best perfor-
mance.
Starting The Engine - Electric Start Units
I. Move choke lever to full choke position.
2. Move throttle lever to “fast”.
3. Turn key to “stall position
4. Release key when engine starts, allowing key to
return to “on’ position.
5. When engine starts, gradually move choke lever to
“no choke” position.
6. Maintain throttle speed at ‘fast” for best perfor-
mance.
Idle Speed
Use the “idle” position on the throttle lever to reduce
stress on the engine when chipping or vacuumfshred-
ding is not being performed. Lowering the engine speed
to “idle” will help extend engine life, as well as conserve
fuel and reduce the noise level of the equipment.
WALK BEHIND VACUUM/SHREDDING
Normal operator position for power-drive, walk-behind
vacuum/shredding is directly behind the unit holding the
units handle securely with two hands. This position pro-
vides the best combination of unit control, forward and
side
vrsrbrlrty, and overall operator safety (Figure 2).

Figure 2. Pull Bail Lever Down And Grip Against
Handle To Engage Transmission
The powered wheel drive is engaged by pulling the full-
width bail lever down where it can be comfortably
gripped against the chipper vacuum handle. Releasing
the bail stops the forward movement and disengages
the transmission, making it easier to turn or maneuver
the unit.
11

Operation
Drive Speed Selector
Forward speed is selected using the speed control lever
mounted on the right side of the handle. The speed
control lever has three positions: slow, medium or fast
(Figure 3).
The ability to select different speeds for differing types of
waste material pick-up and varying surface conditions
helps give you precise control over the unit, which is fur-
ther enhanced by the 3-position vacuum height adjust-
ment and 4-position vacuum intake opening adjustment.
(These adjustment features will be covered later.)
SLOW SPEED -POSITION #l
Slow drive speed is selected when the lever is pulled all
the way back toward the operator into position number
one (Figure 3).
Slow speed is recommended for initial use to help the
operator get accustomed to the driving characteristics of
the unit, and to move the unit very short distances, or for
using the flexible vacuum hose.
Slow speed is also recommended for vacuum/shredding
of wet leaves on heavy density ground cover such as
long, wet grass or thick weeds, or wherever heavier
materials or rougher ground covering requires concen-
trated vacuuming action.
MEDIUM SPEED -POSITION #2
Medium drive speed is selected by moving the lever to
position
#2 (Figure 3).
Medium speed is used when vacuuming leaves that may
be moist, or clinging to medium length ground cover.
FAST SPEED -POSITION #3
Fast drive speed is selected by moving the speed selec-
tor lever to position #3 (Figure 3).
Fast speed is recommended for vacuum/shredding of
light, dry leaves or debris on short or light density
ground cover. It may also be used by experienced oper-
ators to move the Chipper Vacuum long distances.
A CAUTION
Changing drive speed should only be done while
the unit is stopped and the bail lever,+ completely
released. Attempting to change drive speed while
the unit is running may damage the transmission or
cause premature wear of transmission and clutch
components.
Speed Selector Lever
Figure 3. Speed Selector Lever And Positions
A WARNING
Release the bail lever immediately to stop the for-
ward travel of the unit if you see, step on, or sus-
pect to encounter any dangerous debris such as
rocks, gravel, glass, or other hard or sharp objects
anywhere in the path of the Chipper Vacuum.
Clear the debris before proceeding, and dispose of
the material properly to prevent contact with it
again later.
Allowing the Chipper Vacuum to vacuum these
types of materials may result in personal injury to
the operator or bystanders, and will damage the
shredding hammers, reducing shredding efficien-
cy, and voiding the warranty.
CHIPPING
General
Variations in the size and hardness of the materials
being chipped will affect how quickly the material is
pulled in to the chipping knives. Small diameter
softwood branches will chip more readily than larger
diameter hardwood tree limbs, so be prepared for
different feeding speeds when changing the type of
material you are chipping. Kiln-dried dimensional
lumber may be too hard to chip properly.
l Always maintain a stable, well-balanced stance to
one side of the unit when operating the chipper
(Figure 4).
l Never stand directly in front of the chipper cone
when performing chipping operations, since occa-
sional kick-backs or twirling of branches and limbs
may occur, resulting in
you being struck by the tree
limb or branches.
12

Operation
l Hold tree limbs and branches carefully as they are
being put into the chipper cone, releasing your grip
as soon as the self-feeding action of the chipper
knives begin to pull the material in.
l Longer pieces may have a tendency to twirl around
forcefully as they are being drawn into the chipping
knives. Hold the material safely away from the chip-
per cone area until the material is properly controlled
by the chipper cone.
l Never wrap your fingers around tree limbs and
branches, or hold so tightly that you can’t let go
quickly if the tree limb or branch is suddenly and
forcefully pulled into the chipper block chipping
knives. Short pieces may be pushed into the chipper
using longer limbs and branches. Stand to the side
when feeding shod pieces, since they may kick back.

er, and will help you maintain control as the material
is drawn into the chipper block. FLEX HOSE VACUUM/SHREDDING
2. Large, hard or dried-out tree limbs that tend to resist
chipping can be processed by rotating them manual-
ly as you alternately insert and retract them in the
chipper cone.
3. If the material to be chipped is extremely hard and
kicks back forcefully, or cannot be easily controlled
while it is being fed into the unit, remove the material
immediately and set it aside. You may need to sharpen
the chipper blades to process the material. Consult
the repair section of this manual for sharpening instruc-
tions, or take your unit to an authorized service center.
4. If normal chipping operation begins to require addition-
al feeding force to process material, the chipper
knives may be in need of routine sharpening. See the
repair section of this manual for sharpening instruc-
tions, or take your unit to an authorized service center.
5. Always try to maintain adequate control of the tree
limbs and branches being fed into the chipper cone
to prevent them from whipping around and causing
injury to you or damage to the cone. Larger limbs
and branches may have a tendency to kick back
toward the operator, so always be alert as you feed
materials into the cone. Always, feed the large end of
the limb in first.
6. Avoid chipping limbs or branches that you suspect
may have imbedded objects such as hooks, eyelets,
nails, screws, or other metal items that could dam-
age the chipping knives. If possible dispose of them
Vacuum/shredding of confined areas such as plant beds
and decorative landscaping can be performed quickly
and effectively using the 15’ flexible vacuum hose avail-
able for your Chipper Vacuum.
Changing over to flex hose vacuuming can be done
quickly and requires no tools.
To convert your unit for use with the
20’ flexible vacuum
hose, just follow these easy steps:
1. Shut the unit off if it is running, and allow the rotor to
come to a complete stop. (Make sure any material
being shredded or chipped is completely processed
before stopping the unit.) When the rotor is fully
stopped, no noise or vibration will be noticeable.
2. Set the vacuum intake nozzle flap adjustment to the
closed position.
3. Remove the vacuum hose intake plug from the
vacuum hose opening, and store it where it won’t get
damaged or lost (Figure 5). Placing the plug into the
chipper cone opening will keep it readily available
when you want to resume walk-behind vacuuming.
NOTE: When removing the vacuum hose intake plug or
hose connector end, align the seam on the cap or hose
connector with the seam on the vacuum intake opening,
then pull out to snap it out of the intake opening groove,
and unscrew to remove.
13

Operation
4. lnserl the connector end of the vacuum hose into the
intake opening, using care to fully seat the connector
in the opening. If the connector is not fully inserted,
and electrical interlock switch will keep the unit from
starting or running (Figure 6).
5. Place the hand-held vacuum intake nozzle in the
area to be vacuumed, using care to avoid twisting
and minimize bends in the hose.
6. Visually inspect the area to be vacuumed to make
sure it is clear of small pets, non-shreddable materi-
als, and any other hazards that could damage the
shredding hammers if vacuumed into the unit.
7. Perform the Checks Before Start-Up described earli-
er in this manual.
8. Stan the unit in accordance with standard starting
instructions for the type of unit you have.
9. For maximum vacuum force, set the throttle control
on the engine to the maximum speed setting.
lO.To reduce vacuum force, adjust the moveable ring to
gradually open the vacuum adjustment port
(Figure 7).
11. Using the vacuum intake nozzle, vacuum the area
you wish to clear, using care to avoid vacuuming
rocks, gravel, and other hard or sharp objects that
are not shreddable.
12. Use extra care near landscape borders that may be
separating grassy areas from landscape rock or
stone.
13. Se watchful for small children, pets or other animals
that may enter the area.
A WARNING
The chipper vacuum is equipped with an electrical
safety interlock switch which prevents the unit from
operating when the vacuum intake cap or hose is
removed from the inlet opening. See your dealer if
the safety interlock switch is not operating properly.
A DANGER
Never reach into the shredding chamber area of an
electric start unit unless the start key has been
removed and the spark plug wire has been discon-
nected.
Always wear work gloves to protect your hands
from sharp edges and objects that may have been
vacuumed into the unit.

SHUTTING DOWN
When you’re done using the Chipper Vacuum, following
these simple but worthwhile steps will help you shut
down the unit properly so ihat your next use will be
trouble-free.
A DANGER
The engine and surrounding parts become
extremely hot during normal use, and will cause
serious burn injuries if touched before the engine
has cooled. Allow the engine to cool completely
before touching these hot surfaces.
1. When you have completed processing the materials
to be chipped or vacuum/shredded, shut the unit off
and allow the rotor to come to a complete stop
before proceeding
14

Operation
2. Remove the spark plug wire from the spark plug to
prevent the possibility of inadvertent starting. On
electric-start models, remove the key to prevent any-
one from inadvertently activating the electric start
feature. Although the unit won’t start with the spark
plug removed, the rotor will turn, and serious injury
could result if your hands are in the area of the rotor
or chipper knives.
3. Inspect the following areas for any remaining materi-
als that may have built up or become caught during
operations:
l vacuum intake nozzle
l vacuum hose intake opening
l chipper cone
l discharge chute
l engine air intake area
l transmission/clutch area
NOTE: Do not spray water on the transmission to clean
it, A/though it is sealed to protect it during normal use,
doing so may force water into the transmission housing,
causing corrosion or transmission failure. Use a small
brush or air stream to clear debris away from this area.
MATERIAL COLLECTION &DISPOSAL
Direct Bagging
Chipped material may be collected using the discharge
collection bag. Check the bag frequently to make sure it
is filled to a level you can comfortably handle when
removing and emptying the bag.
1. To remove the bag, shut the unit off, and let the
rotor come to a complete stop. Unhook the rear and
front support straps, (Figure 8) then loosen the cinch
strap that holds the bag opening to the discharge
chute. (Figure 9)
2. Pull the bag off and away from the discharge tube
(Figure lo), and using both hands, grip the bag
securely at the front and rear to balance the weight
as you lift it.
3. Place the bag down in the disposal area, and unzip
the zipper opening completely. Lift the bag by the
other end and the contents of the,bag should empty
out easily.
4. Zip the bag closed, and reinstall in the reverse
sequence followed for bag removal. Tighten cinch
strap securely (Figure 11).

Operation
A safe collection area should be located where children,
pets, and bystanders will not come into contact with
chipped material as it is being discharged, or be hit by
deflected pieces that may ricochet away from the collec-
tion area with great force.
When using direct discharge, check the discharge area
frequently for accumulation of material near the dis-
charge port, and make sure the material can be safely
ejected away from the unit. Letting material accumulate
directly in front of the units discharge port may cause a
jam.
