Use only a spark plug of the type 
approved by STIHL and make sure it is 
in good condition – see "Specifications".
Inspect the ignition lead (insulation in 
good condition, secure connection).
Check the condition of the muffler.
To reduce the risk of fire and damage to 
hearing, do not operate your machine if 
the muffler is damaged or missing. –
Do not touch a hot muffler since burn 
injury will result.
Vibration behavior is influenced by the 
condition of the AV elements – check the 
AV elements at regular intervals.
