MAINTENANCE
Maintenance
The ignition lead should always be removed from the spark 
plug before repair, cleaning or maintenance work.
Air filter
The air filter must be regularly cleaned to remove dust and dirt 
in order to avoid:
Carburettor malfunctions
Starting problems
Loss of engine power
Unnecessary wear to engine parts.
Excessive fuel consumption.
An air filter that has been in use for a long time cannot be 
cleaned completely. The filter must therefore be replaced with 
a new one at regular intervals. A damaged air filter must 
always be replaced.
Cleaning the air filter
Remove the air filter cover.
Remove the air filter and check that it is undamaged. Replace 
with a new air filter if you believe it to be defective.
Clean the filter by knocking the filter against a flat surface. 
Never use solvent with petroleum, for example, kerosene, or 
compressed air to clean the filter.
When reassembling, make sure that the filter completely 
seals against the filter holder.
Spark plug
If the machine is low on power, difficult to start or runs poorly 
at idle speed: always check the spark plug first before taking 
any further action. If the spark plug is dirty, clean it and check 
that the electrode gap is 0.5 mm. The spark plug should be 
replaced after about a month in operation or earlier if 
necessary.
CAUTION! Always use the recommended spark plug type! 
Use of the wrong spark plug can damage the piston/cylinder.
Muffler
The muffler is designed to reduce the noise level and to direct 
the exhaust gases away from the operator. The exhaust 
gases are hot and can contain sparks, which may cause fire 
if directed against dry and combustible material.
Regularly check that the muffler is securely attached to the 
machine.
Never use a machine that has a faulty muffler.
!
WARNING! Make sure the cutting attachment 
has stopped before cleaning, carrying out 
repairs or an inspection. Disconnect the HT 
lead from the spark plug. 
!
WARNING! The muffler gets very hot in use 
and remains so for a short time afterwards. 
Do not touch the muffler if it is hot!
