A warranty period of 12 months applies to commercial use and 24 months apply to private use and commences on the day of purchase of the device.

Warranty applies exclusively to failures due to defective material or workmanship. An original sale slip with indication of date of sale must be presented in case of claiming for the warranty rights.

Warranty does not cover unprofessional use such as device overload, violent use, damage caused by third party or foreign materials, failure to comply with operations and assembly manual, and normal wear and tear.

Disposal

Disposal instructions are illustrated in the form of pictograms on the device or packaging. Description of the pictograms is given in "Identification" chapter.

Disposal of transport packaging

Packaging protects the device against damage during transport. Packaging materials are usually selected according to their effect on environment and disposal methods and can therefore be recycled. Returning of the packaging back to circulation saves resources and costs for packaging disposal. Parts of the packaging (e.g. foil, styropor) may be dangerous for children. Risk of suffocation! Keep these parts of the packaging out of reach of children and dispose as soon as possible.

Servicing

The appliance must always be switched off before any servicing and cleaning. Wait until it fully stops. Remove the socket plug.

Servicing works not specified in these Operating Instructions must be performed by authorised staff as there may be dangerous situations the operator is unable to handle. Spare parts may only be replaced by authorised staff.

Cleaning

Every time the appliance has been used, it should be cleaned by a clean cloth or blown with compressed air under low pressure.

Do not use cleaning agents and solvents as they may damage the plastic parts of the appliance.

Winterising

• Clean the appliance thoroughly.
• Keep the appliance in a dry room.
• Provide overall servicing as described in the Servicing section.
• Drain the fuel from the tank.
• Start the appliance after draining the fuel.
• Let the appliance run idle until it stops. This will clean the carburettor from the remaining fuel.
• Let the appliance cool down.
• Remove the spark plug.
• Add a teaspoon of engine oil for 2-stroke to the combustion chamber. Pull carefully the starter cable out a couple of times to make the internal construction elements dip in oil. Refit the spark plug
• Clean the appliance external surface.
• Keep the appliance in a cold and dry place out of reach of ignition sources and flammable materials.
• Pack the knife properly to avoid cutting injuries.

Putting the appliance into operation again

Remove the spark plug.

Pull the starter cable several times so that the combustion chamber gets removed from the remaining oil.

Clean the contacts of the spark plug or fit a new one. Refuel the tank. See the Fuel and oil section.

Start the engine as specified under "Cold engine starting".

Air filter servicing

An air filter that is dirty reduces the engine output due to too low air supply to the carburettor.

A regular inspection is therefore necessary. The air filter should be checked every 25 hours of operation and cleaned if necessary. If the filter is too dusty, it should be checked more often.

1. Remove the air filter cap.
2. Remove the filtration element.
3. Clean the filtration element by tapping or blowing out.
4. Assembly takes place in reverse order.

Never clean the air filter with petrol and flammable solvents.

Spark plug servicing

Socket plug = 0.6 mm

Spark plug torque: 12 - 15 Nm.

Check the spark plug after 10 hours of operation for any dirt and clean it with a copper wire brush if necessary. The spark plug should then be serviced every 50 hours of operation.

1. Remove the socket plug by twisting.
2. Remove the spark plug by the spark plug socket wrench.
3. Assembly takes place in reverse order.

Knives servicing

Sharpen or replace the rotational knife, star knife and string cut-off knife if necessary.
