Function of stop switch and ignition 
system
The ignition is switched off and the 
engine stopped when the stop switch is 
pressed. The stop switch returns 
automatically to the Run position when it 
is released: The ignition is switched on 
again after the engine stops – the engine 
is then ready to start.
Starting the Engine
N Press the manual fuel pump 
bulb (9) at least five times – even if 
the bulb is already filled with fuel.
N Press in the choke knob (8) and turn 
it to the position that suits the engine 
temperature:
Cranking
N Remove the chain scabbard. Check 
that the chain is not touching the 
ground or any other obstacles.
N Place the unit on the ground: It must 
rest securely on the engine support 
and the hook. If necessary, rest the 
hook on a raised support (e.g. a 
branch, mound or something 
similar).
WARNING

working range of the pruner.
N Make sure you have a safe and 
secure footing.

the fan housing and press it down 
firmly – your thumb should be under 
the fan housing.
