and attach the chain scabbard. This avoids the
risk of the saw chain starting unintentionally.
Always carry the chain saw by the handle – with
the hot muffler away from your body, the guide
bar must point to the rear. To avoid serious burn
injuries, avoid touching hot parts of the machine,
especially the surface of the muffler.
In vehicles: Properly secure your saw to prevent
turnover, fuel spillage and damage.
2.5 Cleaning
Clean plastic parts with a cloth. Harsh detergents
can damage the plastic.
Clean the dust and dirt off the machine – do not
use any grease solvents for this purpose.
Clean the ventilation slots if necessary.
Do not use a high-pressure cleaner to clean the
machine. The hard jet of water can damage parts
of the machine.
2.6 Accessories
Only use those tools, guide bars, chains, chain
sprockets, accessories or technically equivalent
components that have been approved by STIHL
for this machine. If you have any questions in
this respect, consult a servicing dealer. Use only
high quality tools and accessories. Otherwise,
there may be a risk of accidents and damage to
the machine.
STIHL recommends the use of genuine STIHL
tools, guide bars, chains, chain sprockets and
accessories. They are specifically designed to
match your model and meet your performance
requirements.
2.7 Refuelling
Gasoline is an extremely flammable
fuel – keep clear of naked flames and
fire – do not spill any fuel – no smok‐
ing.

Switch off the engine before refuelling.
Never refuel the machine while the engine is still
hot – the fuel may spill over – risk of fire!
Open the fuel filler cap carefully so that any
excess pressure is relieved gradually and fuel
does not splash out.
The machine may only be refuelled in a well ven‐
tilated place. Clean the machine immediately if
fuel is spilled. Do not spill fuel over your clothing
– contaminated clothing must be changed imme‐
diately.
The machines can be equipped with the follow‐
ing filler caps as standard:
Cliplock filler cap (bayonet-type)
Place the cliplock filler cap (bayonet-
type) in position, turn as far as stop
and fold the cliplock down.
This helps reduce the risk of unit vibrations caus‐
ing an incorrectly tightened filler cap to loosen or
come off and spill quantities of fuel.
Look out for leaks! Never start the
engine if fuel has been spilled or is
leaking – Fatal burns may result!
2.8 Before Starting Work
Check that your saw is properly assembled and
in good condition – refer to appropriate chapters
in the instruction manual.
– Check the fuel system for leaks, paying spe‐
cial attention to visible parts such as the tank
cap, hose connections and the manual fuel
pump (on machines so equipped). If there are
any leaks or damage, do not start the engine –
risk of fire. Have your saw repaired by a serv‐
icing dealer before using it again.
– Check operation of chain brake, front hand
guard
– Correctly mounted guide bar
– Correctly tensioned chain
– The trigger and trigger lockout must move
freely and spring back to the idle position
when they are released.
– Master Control lever must move easily to
STOP, 0 or †
– Check that the spark plug boot is secure – a
loose boot may cause arcing that could ignite
combustible fumes and cause a fire.
– Never attempt to modify the controls or safety
devices in any way.
– Keep the handles dry and clean – free from oil
and dirt – for safe control of the saw.
