For periods of about 3 months or longer
: Drain and clean the fuel tank in a 
well ventilated area.
: Dispose fuel properly in accordance 
with local environmental 
requirements.
: Run engine until carburetor is dry – 
this helps prevent carburetor 
diaphragms sticking together.
: Remove, clean and inspect the 
cutting tool.
: Thoroughly clean the machine – pay 
special attention to the cylinder fins 
and air filter.
: Store the machine in a dry, high or 
locked location – out of the reach of 
children and other unauthorized 
persons.
: Use a file – see “Special 
Accessories” – to sharpen cutting 
tools. In case of more serious wear 
or nicks: Resharpen with a grinder 
or have work done by STIHL dealer.
: Resharpen frequently, take away as 
little material as possible – two or 
three strokes of the file are usually 
enough. 
To avoid out-of-balance
: After resharpening about 5 times, 
have blade checked on STIHL 
balancer – see “Special 
Accessories” – and rebalanced as 
necessary.
: Resharpen the cutters (1) uniformly 
– do not alter the contour of the 
parent blade (2) in any way.
See cutting tool packaging for additional 
sharpening instructions.
