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.
5. Assembly takes place in reverse order.
Knives servicing
Sharpen or replace the rotational knife, star knife and
string cut-off knife if necessary.
Troubleshooting
The table shows potential failures, their possible cause
and removal options. However, if you are unable to
remove the problem, contact a professional to assist you.
Switch off and unplug the appliance before any
servicing and cleaning.
