dusty or smoky, wear a respirator.

Transporting the Machine

•Always turn off the engine.

•The engine should be turned off when the machine is moved between areas and when transporting or

storing the machine.

Wood Chipper

•When transporting in a vehicle: properly secure your machine to prevent turnover, fuel spillage and damage.

Fuelling

•Petrol is an extremely flammable fuel. Keep clear of naked flames. Do not spill any fuel –do not smoke near

fuel or the machine.

•Always shut off the engine before refuelling.

•Do not fuel a hot engine –fuel may spill and cause a fire. Open the fuel cap carefully to allow any pressure

build-up in the tank to release slowly and avoid fuel spillage. Fuel your machine only in well ventilated areas.

If you spill fuel, wipe the machine immediately –if fuel gets on your clothing, change immediately.

•To reduce the risk of serious or fatal burn injuries, check for fuel leakage. If fuel leakage is found, do not start

or run the engine until leak is fixed.

During Operation

•Make sure you always have good balance and secure footing.

Chute Safety Switch Installation

The safety switch must be installed to prevent the machine from operating if the chutes are not correctly

installed.

After installing the chutes, install the safety switch bracket –to do this, remove a bolt from each of the chutes

and place the bracket in position, then re-install the bolts.

Ensure that the safety switch arm is fully pushing the [black] microswitch "in", otherwise, the engine will not start.

If the safety switch arm is not fully pushing the microswitch "in", remove the safety switch assembly and bend

the arm as shown below (approximately 10mm should be ample), then re-install the safety switch

Operation

Adding Oil

WARNING! Using the wrong oil can damage your engine and void warranty.

Acceptable oil grades; 10W-30, 10W-40, 15W-30 OR 15W-40.

1. Remove the oil filler cap and wipe the dipstick with a clean rag.

2. Fill the recommended oil up to its brim.

3. If the oil level is below the brim of the filler, top up with the

recommended oil.

Starting the Engine

IMPORTANT! Do not restart the unit with material in the hopper chute. The additional drag may cause severe

wear on the drive belt or you may damage the pull starter on the engine and void any warranty.

1. Air Filter

2. Choke

3. Fuel ON / OFF

4. Petrol filler cap

5. Fuel tank

6. Oil filler

7. Pull start & grip

1. Ensure the machine is on stable level ground so it won’t 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. Refer to section on adding oil and fuel to your engine.

3. Slide the choke lever all the way to the left (cold start) or for warm start slide the lever to the centre position

half way between the left (OPEN) and right (CLOSED) sides.

4. Slide the fuel ON/OFF lever to the right (ON) position.

5. Pull the starting cord until the engine starts.

6. Once the engine has warmed up slide the choke lever right to the “OPEN” position.

7. Adjust the throttle to achieve the desired operating speed.

Chipping

IMPORTANT! Never put your hands or fingers in the chipper chute. For the protection of others, do not leave the

machine unattended.

IMPORTANT! Do not move the unit with the engine running. The resultant tilting may starve the engine of oil and

cause it to seize.

IMPORTANT! DO NOT throw the ends of branches that are larger than 15mm diameter into the hopper chute.

Push them down the chipper chute using another piece of wood.

IMPORTANT! DO NOT continue chipping if the drive belt is slipping or smoking. To readjust the belt, see

maintenance information.

WARNING! Never operate the machine with the small maintenance cover plate in its open position or removed.

Serious injury can result.

1. Green timber will chip much faster than dry timber. Do not chip wood that 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.

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 drive. Alternatively,

check if the blades are blunt.

4. Rotating the branches as you chip can reduce the incidence of bark wrapping around the shaft and causing

jamming.

5. If the chipper becomes jammed, the engine should be stopped immediately (if it has not stalled). Disconnect

the spark plug wire and move it away from the spark plug. Remove the offending material before restarting.

Shredding

WARNING! Do not push material into the hopper chute with your hands. Use a green branch or a piece of

softwood. Wear eye protection.

IMPORTANT! Do not attempt to shred objects such as glass, metal, plastic bottles or rocks.

IMPORTANT! Beware of a sudden jerk as the branches are tugged into the hopper.

WARNING! Never put your hands or feet under the machine when it is running.

WARNING! Do not rotate the hopper assembly without first disconnecting the spark plug lead from the spark

plug moving the lead away from the spark plug.

IMPORTANT! If material that is wrapped around the shaft is not removed, the shaft becomes hot and “boils” the

oil out of the shaft bearings. The bearings will then fail.

1. This machine is not designed to be used for Palm leaves and doing so will void warranty.

2. 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 hopper chute as they may wrap around the shaft. This

could cause jamming of the unit and cause severe injury to the operator.

3. Preferably wear gloves when feeding small branches into the hopper chute, hold the branches loosely and

release them long before they contact the rotating blades.

4. Leaves shred very well, especially if they don’t contain long sticks and they are kept loosely stacked in the

hopper 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. Move the machine backwards a short distance as material

builds up underneath.
