Fueling Instructions - Stihl MS 261 Manual De Instrucciones

5 IMPORTANT SAFETY INSTRUCTIONS
￭ Any modification to your muffler or spark arresting screen
could cause an increase in heat radiation, sparks or sound
level, thereby increasing the risk of fire, burn injury or
hearing loss. You may also permanently damage the
engine.
– Never modify your muffler or spark arresting screen.
￭ If the chain saw is dropped or subjected to similar heavy
impacts:
– Check that it is undamaged, in good condition and
functioning properly before continuing work.
– Check that the fuel system is tight and has no leaks.
– Check that the controls and safety devices, including
the chain brake, are working properly, @ 16.
– Never work with a damaged or malfunctioning chain
saw. In case of doubt, have the chain saw checked
by your authorized STIHL servicing dealer.
￭ Genuine STIHL replacement parts are specifically
designed to match your chain saw and meet safety and
performance requirements. Use of parts that are not
authorized or approved by STIHL may cause serious or
fatal injury or property damage.
– STIHL recommends that only identical STIHL
replacement parts be used.

Fueling Instructions

Fuel
WARNING
￭ Gasoline and its vapors are extremely flammable. Your
STIHL chain saw uses an oil-gasoline mixture for fuel. If
spilled and ignited by a spark or other ignition source, it
can cause fire and serious burn injury or property damage.
– Use extreme caution when handling
gasoline or fuel mix.
– Do not smoke or bring any fire or flame
near the fuel or the chain saw.
– Note that combustible fuel vapor may
escape from the fuel system.

Pick a Safe Location for Fueling
WARNING
￭ To reduce the risk of fire and explosion while fueling:
– Fuel your chain saw in a well-ventilated
area, outdoors away from flames, pilot
lights, heaters, electric motors, and other
sources of ignition. Vapors can be
ignited by a spark or flame many feet
away.
– Select bare ground for fueling and move
at least 10 ft. (3 m) from the fueling spot
before starting the engine.
– Wipe off any spilled fuel before starting
your chain saw.
– Take care not to get fuel on your
clothing. If this happens, change your
clothing immediately.
Allow the Saw to Cool Before Removing the Fuel Cap
WARNING
￭ Gasoline vapor pressure may build up inside the fuel tank.
The amount of pressure depends on a number of factors,
such as the fuel used, altitude, and temperature. To
reduce the risk of burns and other personal injury from
escaping gas, vapor and fumes:
– Always shut off the engine and allow it to cool before
removing the fuel cap.
￭ The engine is air cooled. When it is shut off, cooling air is
no longer drawn across the cylinder and engine
temperatures will rise for several minutes before starting
to cool. In hot environments, cooling will take longer. To
reduce the risk of burns and other personal injury from
escaping gas vapor and fumes:
– Allow the chain saw to cool. If you need to refuel
before completing a job, turn off the machine and
allow the engine to cool before opening the fuel tank.
