3. Obey all local regulations for the storage and handling of fuel.
4. Do not smoke when fueling, or fuel where fumes could be ignited by fire or sparks.

1

5. Do all fueling outdoors over non-flammable surfaces. If fuel is spilled on the unit, wipe the unit dry and
properly dispose of the wiping rag. ALWAYS MOVE THE UNIT AT LEAST 10 FEET (3 meters) from
the fueling spot and fuel supplies before starting the engine.
6. Always remove the engine fuel cap very slowly to equalize tank pressure and avoid fuel spurting out.
Keep your face and eyes away from the tank while loosening the cap.
7. Do not fuel a running or hot engine. Do not loosen the fuel cap until the engine has stopped. Then
wait several minutes for the engine to cool before pouring fuel.
Operate the Chipper/Shredder only on a level surface. Do not operate the unit on paved or gravel
surfaces.
Before starting, check that all screws, nuts, bolts and other fasteners are properly secured.
OPERATION
All chute safety covers and hand stops, deflectors and feed chutes must be in proper position. Do not
operate if any safety devices or fastening parts are missing from the unit.
Before starting make sure that the grinding chamber contains no foreign objects that could interfere with
operation or eject from the intake openings at high speed.
Operate only when there is good visibility. Do not operate at dusk or at night.
Do not let hands or any other part of your body, or your clothing, enter either of the Chipper/Shredder
intake openings, or go near the discharge opening unless the engine spark plug wire is disconnected and
Chipper/Shredder shaft is not rotating.
The zone of operation is anywhere except on the discharge side or in front of the Chipper chute. Do not
stand directly in front of the Chipper feed chute. Do not peer down into the Shredder hopper. Materials
can be thrown back out of the intakes. Do not go on the discharge side of the unit during operation.
Allow engine to warm up. Then operate at maximum throttle speed setting. Never change the engine
governor setting or over speed the engine to gain power.
Side branches should be lopped off to avoid clogging the hopper or chute.
DISCONNECT THE SPARK PLUG WIRE FROM THE SPARK PLUG TO ENSURE AGAINST
ACCIDENTAL STARTING DURING ANY OF THE FOLLOWING OPERATIONS:
1. Repairsoradjustmentstounitorengine.
2. Beforetransportorstorage,orwheneveryouare going to leave the unit unattended.

2

MAINTENANCEANDSTORAGE
Clean leaves, debris and fuel off the unit to avoid the possibility of fire.
Keep the unit in good working condition. Clean the unit at regular intervals, and check each time for loose or
missing parts.
Do all items of maintenance explained in this Chipper/Shredder Owners Manual. Do not attempt disassembly
or repairs not included in instructions from BCS or the engine manufacturer. Some adjustments and internal
servicing of both engine and the BCS Chipper/Shredder should be done by BCS trained service personnel at
an authorized BCS servicing dealer or distributor.
Shut down the engine immediately if a foreign object gets into the grinding chamber, or the unit suddenly
makes loud noises or vibrates excessively.
When the Chipper/Shredder is stopped for servicing, inspection, storage or to change an accessory, make
sure the spark plug wire is disconnected from the spark plug. Allow the machine to cool before making any
inspections, adjustments, etc.
Allow the unit to cool before putting it away. Keep it out of the reach of children, and where sparks cannot
ignite the gasoline fumes.
Do not store the unit with fuel in the system. Disconnect the fuel line at the carburetor inlet and drain the fuel
into a fuel container. Then reconnect the fuel line. Start and run the engine until it
stops from lack of fuel.
Dispose of the drained gasoline safely.
Store the cleaned and drained Chipper/Shredder in a well-ventilated place, protected from dampness and
the weather.

3. ALWAYSOPERATETHECHIPPER/SHREDDERATFULLTHROTTLE.
4. Chippingandshreddingmaybedonesimultaneously.
DANGER
Material can be thrown out from both feed and discharge openings.
1. Wear safety goggles and a hat.
2. Do not look into shredder hopper or place your head over it when the unit is running.
3. Do not go on the discharge side of the unit or directly in front of the Chipper chute.

. WARNING
Inspect what you plan to feed into the hopper. Remove glass, metal, brick, stones, long or thick
branches, or anything else that could damage the machine or fly out at high speed.

5

CHIPPINGWOOD
1 Wood with a diameter of 3-3/4” can be fed through the Chipper chute.
2 Put the thickest end of the branch into the chute. Side branches must be bent to fit or lopped off. Try
to find the right feed pressure being careful that it is not too much! Do not over feed the unit. Pull back
when engine slows down and wait for its speed to resume before continuing to feed wood. The
engine must maintain its speed under load in order to keep the centrifugal clutch fully engaged.
Proper feed pressure and engine speed are important for the life of the unit.
3 NEITHER PULL OUT NOR PUSH IN the short pieces with your hands. Use the next log or branch to
feed the short pieces through the Chipper each time. Short pieces sometimes feed themselves
through the chipper but very often they are thrown out.
DANGER
DO NOT PUT HANDS DOWN INTO THE CHUTE WHEN THE UNIT IS RUNNING.
WARNING
Do not go on the discharge side of the unit or stand directly in front of the intake chute when
feeding the Chipper. Keep to one side of the chute.

6

SHREDDING
1. Be very careful about what you put into the hopper. The Shredder cannot handle cloth, string, plastics,
glass, rubber, rocks or paving, brick, large wood chunks, metal, thick branches and long vines.
Any
material more than two centimeters (about ¾”) thick can jam the Shredder.
2. Soggy soil, green garden wastes and wet grass clippings may need to be mixed with dry wood chips or
leaves to avoid clogging the Shredder.
3. Preparation of the material may help in feeding it through the hopper. Cutting branches off stems, for
example, helps the mass of material slide down the hopper walls. Adding too much material at a time
can clog the works. Pushing thick weeds or branches into the hopper with force overfeeds the flails
(knife blades) and jams the Shredder. Rods and tubes can replace the curved “Swiss cheese” screen
for improved shredding of wet materials or finer chips (see “Changing Discharge Screen").
4. Cleaning the Bio 100 discharge screen or clearing internal blockage requires temporary removal of the
belt cover and the discharge screen. It may also be necessary to remove the hopper to remedy
internal blockage. In order to remove objects between the Chipper hopper and the rotating parts it is
necessary to remove the hopper assembly, which is held by eight sets of M8
x 20 bolts, lock washers
and hex nuts.

DANGER
Shredder grabs and pulls material down into the
hopper with surprising speed. Do not wear rings,
bracelets, jewelry, watches or any other items
that could be caught by the material, drawing
your hands into the Shredder. Hold the material
very lightly. Do not force the material into the
shredder. Gloves, when worn for shredding,
should be large enough to slip off your hands if
caught by the material.
WARNING
Always shut down the engine and wait until all
movement stops before clearing the hopper or
discharge screen, and before removing the
hopper to remove a blockage.

IMPORTANT
THIS DISASSEMBLY ROUTINE SHOULD BE FOLLOWED TO REMOVE THE SCREEN EITHER FOR
CLEANING OUT DEBRIS OR REPLACEMENT WITH RODS AND TUBES.
1. Shutoffengine,disconnectthesparkplug wire and wait for unit to stop rotating before starting to work.
2. Remove the belt cover, held in place by 2 M8 bolts, flat washers and hex nuts.
WARNING
The Bio 100 has a centrifugal clutch and the Chipper/Shredder shaft may continue to
rotate silently after engine shut-down. After shutting down the engine, check the paint mark
on the end of the Chipper/Shredder shaft to be sure the shaft has stopped rotating before
you work on the unit.
WARNING
The engine-grounding lever over the spark plug boot has a sharp point to penetrate the boot
and ground the ignition. Be careful of this point when disconnecting the spark plug wire.
