Putting the appliance into operation again

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.
