Preparing the Engine
CAUTION
If a blue plug is fitted beneath the petrol filler cap it may be
discarded. It is for transportation purposes only.
PLEASE READ AND UNDERSTAND THE ENGINE MANUFACTURES ENGINE OWNERS MANUAL PRIOR TO OPERATING
THE MACHINE.
When filling the fuel tank, always leave an air space of about
5mm to allow for expansion of the fuel.
CAUTION
CAUTION
DO NOT START your engine before making sure that it has
been filled with the right amount of the correct grade of oil.
See engine instruction book for details.
USE ONLY CLEAN FRESH PETROL AT ALL TIMES, preferably un-leaded, with an octane rating of at least 77. Four
stroke (cycle) engines use straight fuel.
ENGINE MAINTENANCE
OIL
Engines are shipped without oil. Place the unit on a level position, unscrew the ‘OIL FILL’ cap and slowly pour oil into the
sump. Fill untill the oil begins to overflow out the filler hole. The
capacity is approximately 600 ml. Check the oil level before running the engine, screw the filler cap firmly in place. See engine
instruction book for details.
Regular attention to a few simple items will ensure long and trouble-free service from your unit. Carry out the regular maintenance described in the engine manual, and check the engine
mounting bolts regularly to be sure they are tight.
NOTE: THE ENGINE IS WARRANTED BY THE ENGINE
MANUFACTURER AND NOT MASPORT. YOUR SPECIALIST
MASPORT SERVICE DEALER CAN ASSIST WITH ENGINE
RELATED WARRANTY MATTERS.
WARNING
OIL FILL
CHANGING THE ENGINE OIL.
ENGINES should be checked for oil level every 8 hours running
(or daily), and the oil should be drained and replaced after every
50 hours of use.
FUEL
WARNING
PETROL VAPOUR IS HIGHLY FLAMMABLE AND EXPLOSIVE. HANDLE WITH EXTREME CARE. STORE IN AN
APPROVED CONTAINER. DO NOT FILL TANK WHEN
ENGINE IS RUNNING OR IS STILL HOT. DO NOT ALLOW
OPEN FLAME, MATCHES OR SMOKING NEARBY. FILL
TANK OUTDOORS IN A WELL VENTILATED AREA. WIPE
AWAY ANY SPILLS AND MOVE THE MOWER AWAY FROM
ANY PETROL FUMES BEFORE STARTING ENGINE.

Before making any adjustments to your unit make sure that
the engine is turned off and that the blade has STOPPED
ROTATING. Always disconnect the spark plug wire and make
sure it cannot accidentally contact the spark plug before
touching anything under the housing.
Operating Instructions
Operating Instructions
TRANSPORT
STARTING
1. To move the unit around, put one foot on either wheel and tilt
the unit backwards until it passes its balance point.
1. Ensure the Recycler is on stable level ground so it wont tip
over. Do not operate the machine on a hard surface such as concrete, as discharged material will rebound and may damage people or property.
2. Before starting the engine, check that the engine mounting
plate is roughly horizontal. If not refer to maintenance instructions.
3. Turn switch to “ON” position.
DANGER: NEVER MOVE UNIT WHILE THE ENGINE IS
RUNNING.
4. Both Units. Push choke lever to
position and throttle lever
to fast position.
5. Pull the starting cord until the engine starts. Push the choke
lever off.
6. Adjust the throttle to achieve the desired operating speed.
7. Once the engine is hot, it is not necessary to use the choke
when restarting.
8. Do not restart the unit with material in the chipper tube or
shredder chute. The additional drag may cause severe wear on
the drive belt or you may damage the pull starter on the engine.
Chipping
IMPORTANT NEVER PUT YOUR HANDS OR FINGERS IN THE
CHlPPER TUBE.For the protection of others DO NOT LEAVE
THE MACHINE UNATTENDED WHEN IT IS RUNNING.
1. Branches up to 65mm diameter (50mm for the 3.5 model) can
be chipped using the chipper tube on the right side of the unit.
Green timber will chip much faster than dry timber. Do not chip
wood which contains nails.
2. If the unit cannot be placed on the surface on which the chips
will be spread, then a sheet of plastic or canvas can be laid
under the machine to collect the chips. Alternatively, a plastic bin
can be placed under the machine through the front support. (The
bin is not supplied with the unit.)
2. When crossing rough terrain or sloping areas, hold the
handle/chute firmly at each side with both hands (to prevent tipping). In some instances it may be easier to walk backwards,
towing the unit.
3. With the chute removed, the unit will fit in some larger station
wagons, but it must be tied in position if left upright. Once the
engine is filled with oil, it cannot be tipped on its side unless the
oil is drained out.
PREPARATION
1. Wear safety glasses at all times while operating the machine.
Hearing protection is also recommended, especially for
extended operating periods.
2. Avoid wearing loose-fitting clothing.
3. Before starting the machine, check that all screws, nuts, bolts
and other fasteners are properly secured. Replace damaged
or unreadable warning and operating decals.
4. Use extra care in handling gasoline and other fuels. They are
flammable and vapours are explosive.
a)
Use only approved containers.
b)
Never remove fuel cap or add fuel with engine running.
Allow engine to cool before refuelling Do not smoke
c)
Never refuel the machine indoors.
d)
Never store the machine or fuel container inside where
there is an open flame, such as a gas water heater.
NOTE: DO NOT MOVE THE UNIT WITH THE ENGINE RUNNING. THE RESULTANT TILTING MAY STARVE THE ENGINE
OF OIL AND CAUSE IT TO SEIZE
3. If the engine is slowing substantially while chipping, reduce the
rate you are feeding branches into the machine. This will also
make the resultant chips smaller and will extend the life of the
belt drive. Alternatively, check if the blade is blunt.
NOTE: DO NOT throw the end of branches which are larger than
15mm diameter into the shredder chute. Push them down the
chipper tube using another piece of wood.
4. Rotating the branches as you chip can reduce the incidence of
bark wrapping around the shaft and causing jamming.
5. Branches with multiple smaller branches connected can be fed
into the chipper tube until you are left with a handful of small
leaves and small branches. This handful can then be dropped
into the shredder chute.
6. If the chipper becomes jammed, the engine should be stopped
immediately (if it has not stalled). Remove the offending material
before restarting. This may involve lowering the shredder mesh,
turning the shredder assembly backwards (with the spark plug
disconnected) and prising the material out of the tube with a long
knife, screwdriver etc.
NOTE: DO NOT continue chipping if the drive belt is slipping or
smoking. To readjust the belt, see maintenance information.
NEVER operate the machine with the small maintenance cover
plate in its open position or removed. Serious injury would result
if someone put their finger into the hole which is under the cover
plate.
5
Shredding
DANGER:
A. DO NOT PUSH MATERIAL INTO THE SHREDDER CHUTE
WITH YOUR HANDS. USE A GREEN BRANCH OR A PIECE
OF SOFTWOOD.
B. WEAR EYE PROTECTION.
1. Many organic materials as well as leaves and branches can be
shredded. Vines will need to be cut into short lengths (about
300mm) before feeding them into the shredder as they may wrap
around the shaft. This could cause jamming of the unit and could
also cause severe injury to the operator.
IMPORTANT DO NOT ATTEMPT TO SHRED HARD OBJECTS
SUCH AS GLASS, METAL, PLASTIC BOTTLES OR STONES.
2. Preferably wear gloves when feeding small branches into the
shredder chute, hold the branches loosely and release them long
before they contact the rotating blades.
BEWARE OF A SUDDEN JERK AS THE BRANCHES ARE
TUGGED INTO THE SHREDDER.
3. Branches over 15mm diameter will rattle around inside the
shredder for some time and may damage the shredding screen.
These branches should be fed into the chipper tube instead.
4. Leaves shred very well, especially if they don’t contain long
sticks and they are kept loosely stacked in the shredder chute,
i.e., don’t force them down the chute if it becomes clogged. Stop
the engine and free the jam.
5. Keep watching the area under the machine to ensure that the
shredded material has not built up to the point where further
shredded material cannot escape. This may prevent proper discharge and could cause kickback of material through the feed
opening. Use a stick to push material aside, not your foot.
6. Control the rate of feeding material into the shredder chute so
that the motor is not overloaded. In particular, try and avoid rapid
changes in engine speed caused by instantaneous bulk feeding
DANGER: NEVER PUT YOUR HANDS OR FEET UNDER THE
MACHINE WHEN IT IS RUNNING.
7. If the shredder screen becomes clogged, stop the engine and
pull the R clip from the pin which protrudes under the belt guard
near the front leg. Using the T grip below the chipper tube, pull
the pin out of the shredder screen. Generally this will cause the
screen to open downwards. If it is jammed, it can be gently
prised down using the shredder rod or a large screwdriver.
DANGER: DO NOT ROTATE THE SHREDDER ASSEMBLY
WITHOUT FIRST DISCONNECTING THE SPARK PLUG LEAD
FROM THE SPARK PLUG.
8. Once a jam is cleared, push the screen into place and replace
the pin. Note that the T grip must be horizontal for the pin to go
fully through the screen. Replace the R clip.
9. If the screen is blocking repeatedly when shredding material
such as wet leaves, try mixing some dry material with the wet
material to scour the screen clear or use the (optional extra) bar
grate. See paragraph 11.
10. After shredding “stringy” material such as palm leaves,
remove the shredder chute and check that they have not
wrapped tightly around the ends of the rotor, inside the chamber.
If so, carefully remove them with a flat screwdriver. Some varieties of palm leaves can be cut in the chipper tube.
NOTE: If material which has wrapped around the shaft is not
6
removed, the shaft becomes hot and ‘boils’ the oil out of the shaft
bearings. The bearings will then fail.
11. USE OF (OPTIONAL EXTRA) BAR GRATE. For shredding
soft, bulky or wet material such as weeds or vegetable matter, an
optional bar grate can be purchased. To fit the bar grate, turn the
engine off, remove the spark plug lead and the belt guard. Pull
out both R clips securing the shredder mesh rods, remove the
rods and the mesh. Insert the bar grate from below and insert the
rods through the grate. Reconnect the R clips, the belt guard and
the spark plug lead.

1.1 Become familiar with the owner’s manual before attempting
to operate this equipment.
1.2 Do not allow children to operate this equipment.
1.3 Do not operate this equipment in the vicinity of bystanders..
1.4 Carbon monoxide can be extremely dangerous in enclosed
areas; do not run the machine in an enclosed area since the
exhaust from the engine contains carbon monoxide, which is
colourless, odourless and tasteless.
1.5 Do not allow hands or any other part of the body or clothing
inside the feeding chutes, discharge area, or near any moving
part.
1.6 Before inspecting or servicing any part of the machine, shut
off the power source, disconnect the spark plug lead from the
spark plug, and make sure that all moving parts have come to a
complete stop.
2. OPERATION
2.1 When feeding shreddable material into the equipment be
extremely careful that pieces of metal, rocks, bottles, cans or
other foreign objects are not included.
2.2 If the cutting mechanism strikes any foreign objects or if the
machine should start making any unusual noise or vibration,
immediately shut off the engine and allow the machine to stop.
Disconnect the spark plug wire from the spark plug
and take the following steps:
1) Inspect for damage.
2) Replace or repair any damaged parts.
3) Check for and tighten any loose parts.
Do not attempt to repair the machine unless you are competent
to do so.
2.3 Keep the engine clean of debris and other accumulations to
prevent damage to the engine or possible fire.
2.4 Keep all guards and deflectors in place and in good working
condition .
2.5 Always stand clear of the discharge area when operating this
machine.
2.6 Keep your face and body away from the feed opening.
2.7 Do not overreach. Keep proper balance and footing at all
times.
2.8 Do not tamper with the engine governor settings on the
machine: the governor controls the maximum safe operating
speed and protects the engine and all moving parts from damage
caused by overspeed. Seek authorised service if a problem
exists.
3. MAINTENANCE AND STORAGE
3.1 When this equipment is stopped for servicing, inspection, or
storage, or to change an accessory, make sure the spark plug
lead is disconnected from the spark plug. Allow the machine to
cool before making any inspections, adjustments, etc. Maintain
the machine with care and keep it clean.
3.2 Store the machine out of the reach of children and where
gasoline vapour will not reach an open flame or spark. For
extended storage periods, drain the petrol. Always allow the
machine to cool before storing.
Basic Maintenance
TOOLS REQUIRED
a) Two 13mm open-ended ring spanners
b) 5mm allen key.
c) 10” crescent.
1. Every 5-10 hours of operation, check the oil level and top up if
necessary. Change the oil in accordance with the instructions in
the engine booklet.
2. Regularly check the condition of the engine air cleaner, especially in dusty environments.
3. The drive belt may stretch after a short period of use, but
should then stabilise for a considerable time if not overloaded or
constantly slipping.
If the engine is not approximately level (i.e. if it is hanging backwards away from the chute) then the spring pressure on the belt
may be reduced and the belt may slip.
To return the engine to level: Remove the belt guard; loosen
the four engine mounting bolts using two 13mm spanners; raise
the engine mounting plate until the engine is tilting slightly forward; pull the engine back in its mounting slots and tighten the
two rear engine mounting bolts. Check that the engine is now
level, tighten the remaining engine bolts and replace the belt
guard.
NOTE:Replace the drive belt when the engine has reached the
end of its slotted hole and is sloping backwards.
4. If the engine is vibrating badly, the 10mm engine pivot bolts
under the engine mounting plate may need tightening. Do not
tighten them fully, and after tightening check that the engine still
pivots by lifting it by hand. If it does not pivot, the belt will slip as
the weight of the engine keeps the belt tight. Removing the pivot
bolts and greasing them at least once a year will increase the life
of the pivot bushes. New Nyloc nuts may be necessary after
removing them a few times.
5. To remove the chipper blade for sharpening/replacement .
• Disconnect the spark plug lead from the spark plug
• Loosen the upper bolt on the maintenance cover plate and
remove the lower bolt.
• Remove the plastic shredder chute (4 bolts).
• Rotate the maintenance cover plate to expose the hole under
the plate.
• Rotate the shredder-chipper rotor until the chipper blade is
opposite the two maintenance holes.
• With a sharp object such as a nail, remove wooden debris from
the allen key holes in the two countersunk chipper blade bolts
• Remove the bolts and the chipper blade using an allen key and
a 13mm spanner. [BEWARE OF THE SHARP EDGE ON THE
CHIPPER BLADE.]
• Sharpen blade to 45°. Do not remove more than 2mm of material as this will cause rotor imbalance, i.e., the minimum blade
dimensions are:–
30mm
45°
• Never reuse a cracked chipper blade.
• Use new Nylock nuts when replacing the chipper blade, and
new bolts if they appear damaged. Ensure the blade is sitting flat
on the rotor surface before tightening .

the maintenance hole.
8. Check the condition of the shredder shaft. If it is badly grooved
(i.e. grooves greater than 1 mm deep) then replace it. Similarly
replace worn spacers (see lengths below.)
9. Repeat the same operation for the other two shredder shafts .
10. When replacing the shafts and blades, use new Nyloc nuts
on the shaft bolts and install new bolts if they are damaged or
worn. Do not reuse cracked or badly worn blades.
11. The blades must be installed as shown below. Of particular
importance, the blade X must be opposite the chipper blade or it
will hit the chipper blade bolts when it rotates on its own shaft.
Disconnect the engine from the unit by removing the belt guard,
the drive belt, the belt tensioning spring, and the two engine pivot
bolts.
ROTOR REMOVAL
1. Remove the 3.5” pulley from the rotor assembly by first removing the circlip, then loosening the boss screw and withdrawing
the pulley using a puller. Penetrating fluid injected through the
boss screw hole may assist removal.
2. Remove the shredder chute.
3. Remove the 13mm bolt from the rotor shaft adjacent to the
chipper tube.
4. Take the 4 nuts from the bearing bolts.
5. Loosen all four bearing boss screws using an 1/8” allen key.
6. With a brass (or similar) drift, drive the shredder shaft partially
through the bearing on the chipper tube side of the machine.
