Before the first start-up

The motor of the garden shredder is supplied without petrol and oil in it.

Fuel the garden shredder as described under "Fuelling".

Fuelling

Oil

Use high-quality oil of the classes SF, SG, SH SJ or better.
Together with the recommended oil no other specific additives are needed.
Do not mix the oil with petrol.

Air-cooled engines operate with higher temperatures than vehicle engines. When using non-synthetic multigrade oil types (5W-30, 10W-30, etc.) at temperatures above 4^ C a higher than normal oil consumption occurs. The oil level needs to be checked more frequently.
* When using the engine at temperatures under 4^ synthetic oil must be used. Otherwise the engine may be damaged.
When using SAE 30 oil at temperatures under 10^ it is hard to start the engine and the cylinder bore may be damaged due to insufficient lubrication.

Oil capacity: 0.6 l

Oil filling

1. Remove the oil filling plug (3). 16
2. Slowly pour oil into the hole.
3. Tighten the oil filling plug.
4. Wipe off oil residues/spilling.

Oil level checking

Remove the oil filling plug (3).

Petrol

Utmost care is required when handling fuel. Keep away Keep away smoke and open flames (risk of explosion).smoke and open flames (risk of explosion).

Clean fresh non-leaded petrol having an octane number of 85 as a minimum.
Do not fill in leaded petrol, diesel or other non-approved fuels.

Do not use petrol having a smaller octane number than 85 ROZ. This may lead to severe engine damages due to increased engine temperatures.
If you frequently operate the device at high speeds, you should use petrol with a higher octane number.
The use of unleaded petrol is recommended for environment protection reasons.

Storing fuel (petrol)

Fuels have only a limited shelf-life, they are subject to ageing. Outdated fuels and fuel mixtures may result in starting problems. Therefore, store only that quantity of fuel which you can use within a month.
Only store fuels in containers approved and identified for this. Keep fuel containers in a dry and safe area.
Make sure that fuel containers are kept out of the reach for children.

Working with the garden shredder

Do not forget!

• Choose a working position alongside the equipment or behind it. Never stand near the ejection opening.
• Longer material that is protruding from the device could spring back when it is drawn in by the blades! Observe safety distance!
• Never reach into the filling or ejection opening.
• Keep your face and body away from the filling opening.
• Never place hands, other parts of the body or clothing into the filler funnel, ejection channel or in the vicinity of other moving parts.
• Check that no chopped residues are in the filling hopper before switching on the equipment.
• Only start shredding when the petrol engine has reached its max. speed.
• Do not tip or tilt the machine when the engine is running.
• When filling, be careful that no pieces of metal, stones, bottles or other objects unintended for processing, enter the filling hopper.
• Immediately switch off the equipment and allow it to come to a stop, if foreign objects enter the filling hopper or if the equipment starts to make unusual noises or vibrates. Carry out the following checks:

inspect for damage,
- replace or repair damaged parts,
- check the equipment and tighten loose parts.

You must not repair the equipment yourself if you are unauthorized to do so.

What can I shred?

Yes:

organic household and garden waste

e. g. hedge and tree cuttings, bushes, perennial herb, dead flowers

No:

• glass, metal, plastic, plastic bags, stones, cloth, roots with soil, food left-overs, fish or meat.

What kind of material can be

shredded with the filling hopper (1) and how to feed it?

Shrub parts, leaves, organic waste and thin branches can be chopped.
Thin and long shrub parts and branches are dragged in rapidly. Release the material quickly.
Process material which contains a lot of water and tends to sticking alternately with woody material to prevent the device from getting blocked.
Do not feed too much material at the same time into the filling hopper to prevent the cutting tool from getting blocked.
Use a wooden rod to feed hardly accessible material to the cutting tool.

What kind of material can be

shredded with the side hopper (31) and how to feed it?

Thicker branches must be fed through the side hopper.
Make sure to feed the branches slowly to avoid the cutting tool from getting overloaded or blocked.

Special tips on shredding:

Branches, twigs and wood should be broken down immediately after they have been cut.
- Material of this kinds gets very hard when it is dry, and the maximum allowed branch diameter to be processed has to be reduced.
Remove any side shoots from branches with a large number of twigs.
Feed branches with larger diameter slowly.
Do not allow the shredded material to pile up too high in the area of the ejection opening. This can lead to shredded material blocking the ejection channel, and backing up to the filler opening.
Clean out the filler opening and ejection channel thoroughly if the machine becomes blocked. Before doing this, stop the engine and disconnect the spark plug connector.

Please do not exceed the maximum branch diameter specified (cutting fresh wood) for your appliance ( see p. 22). Depending on the wood's nature and freshness the maximum branch diameter the machine can process may be smaller.

The blades largely pull the material into the machine by themselves.
Immediately stop the engine when the cutting unit is blocked to prevent the engine overloading. Eliminate the fault before restarting the engine.

Maintenance and Care

Before each maintenance and cleaning work

• Stop the engine.
• Wait until the cutting device does not longer move.
• Remove the spark plug connector.
