HEALTH & SAFETY AT WORK:
This Chipper has been designed and constructed so that, in so far as reasonably practical, it will not
endanger the safety and health of those working with it. This is however subject to the machine
being properly used and maintained according to the conditions stated in this manual and
elsewhere, which have been found necessary as a result of the research and testing of the Supplier.
Assembly Instructions
On receiving your Bushranger BRC40 Chipper,
the Inlet Chute will need to be attached.
1. Remove the machine from its packaging.
2. Remove the bolts from the machine where
the inlet chute will be attached.
3. Hang the Inlet Chute on the rear of the
Chipper and attach using the two M10x25 nuts and bolts (provided). Tighten the bolts with two
spanners.
4. Fill the engine with oil. Use high quality 10W30 oil. Refer to the supplied engine operation manual
for the quantity of oil needed to fill the engine and other regular maintenance procedures relating to
the engine.

Operating the Chipper
SAFETY NOTICE
WARNING: PREVENT ACCIDENTS
Before operating the Chipper it is essential that:
The operator reads and understands this manual and has followed the safety precautions described.
The maintenance check has been properly carried out and the Chipper is in good working order.
The operator must use safety equipment, including gloves, eye protection, ear muffs and covered
shoes. Failure to do so could result in damage and risk the health and safety of the operator.
Ensure the Chipper is on a flat, firm surface.
Ensure all nuts and bolts are properly tightened.
Ensure all safety guards are in place.
Make sure the inlet chute is free of debris before starting the unit.
Check the engine oil level.
Operation
Preventing accidental injury is the sole responsibility of each user of this machine. Ensure the
operator of this machine is thoroughly familiar with the operation and safety procedures described
in this manual.
Always make sure that the machine has been switched off, and the cutter is stationary, before the
machine is moved to a different location, or opening the cutter housing.
Refuelling the Engine.
Before operating the Chipper, fuel needs to be added to the fuel tank.
During use, the engine should be left to cool before refuelling.

Introducition
Starting/ Stopping the machine:
Cold Start
Ensure the ignition switch is set to the ON position.
Ensure the petrol tank is sufficiently full, turn the fuel tap to the ON position.
Slide the Choke lever to ‘Full Choke’ position.
Slide the Throttle lever across to the fastest setting.
Pull the start cord with sufficient force to start the engine.
Once the engine has started slide the Choke lever across to the off position.
Hot Start:
Follow the procedure for a cold start, but leave the choke lever in the ‘off’ position.
For more detailed instructions on the operation and maintenance of the engine, please refer to the
supplied engine owners manual.
Stopping the Engine:
Turn the ignition switch to the ‘off’ position and wait for the cutter to stop rotating. Turn the fuel tap
to the OFF position.

Introducition
Feeding Material into the Machine.
Ensure that no contaminated material is fed into the Chipper. Metal, stones, sand and dirt will harm
the cutting edge of the blades, leading to undesirable performance. Avoid feeding stringy materials
such as cabbage trees into the Chipper as these can wrap around the cutter shaft bearing, damaging
the seals.
Avoid feeding short pieces of wood into the Chipper. These short pieces tend to bounce off the
cutting disc and act erratically. To chip these short pieces of material, combine their feeding with
larger lengths of wood.
Freshly cut green material will be cut more efficiently that old wood which has dried over an
extended period.
The maximum diameter of branches that the Chipper can process is 40mm, depending on the
hardness of the wood. The Chipper has been designed to self-feed the material into the cutting
blades. Because the Chipper has a large inlet chute, larger material has the tendency to stall the
machine. To aid in stopping this, manually feed these larger branches down the chute, allowing the
engine to maintain a high speed to effectively cut the material without stalling.
Ensure that the material is fed into the inlet chute wooded end first, leaving the leafy end to be
pulled through. This aids in the self-feeding of the machine and helps the bushy material be
effectively cut. Some of the smaller growth coming off the main branch may need to be trimmed so
that it doesn’t get jammed at the bottom of the inlet chute. As the operator becomes more familiar
with the machine, they will be able to judge which branches need to be trimmed.
If material becomes clogged at the bottom end of the inlet chute, use a spare branch to push the
blocked material down into the cutting blade. Ensure that the spare branch is of sufficient length so
that the operator does not have to reach inside the chute.
The Chipper is able to process material other than just branches. Leaves, prunings and vines can be
fed into the Chipper.
Unclogging the Cutter
If the Chipper stalls through overloading or clogging, stop the engine, ensure that the cutting disc
has completely stopped and the ignition switch is in the OFF position and the spark plug
disconnected. Open the cutter housing cover and remove all the material from the housing. Close
the cutter housing, and restart the machine. Refer to the starting procedure at the beginning of this
section for guidance. If any stringy material becomes wrapped around the rotor shaft, remove it
before it works itself into the bearing.

Introducition
Maintenance
Before carrying out maintenance or service work:
Stop the engine and wait for the cutting disc to stop rotating.
Allow the machine to cool
Find a dry, clean, level area.
Study and follow the published service procedures.
Do not work on a machine with loose clothing that could get caught in moving parts.
-Check for any loose nuts and bolts.
-Check the belt tension. The belts will stretch when they are new.
-Grease the cutter shaft bearings. Ensure not to overfill with grease as the seals could pop
out of the housing.
For engine maintenance refer to the Engine service manual document.
Tensioning/ Replacing the Belt
Remove the belt cover and check the tension of the
belt. To tension the belt, loosen and reposition the
M12 locking nuts which set the engine height then
refit the belt cover.
Adjusting the Anvil
Remove the inlet chute and loosen the two
bolts holding the anvil. Set the distance from
the edge of the anvil to the cutting blade to
2mm. Retighten the bolts and refit the chute.

Introducition
Replacing the Cutting Blade
With the engine switched off, the cutting disc stationary
and the spark plug disconnected, open the cutter
housing door and remove the two cutting blades. The
blades are double sided so in the first instance can be
rotated and refitted. Take the blades to your authorised
service dealer to resharpen the blades if both sides are
worn.
Cleaning and Storage
If you wish to clean the machine, wait for the engine to cool down and hose the machine down
inside and out. Ensure that the drainage hole at the bottom of the cutter housing is not blocked.
Do not wash the chipper with high pressure water blasters.
