Fueling Instructions

Fuel
WARNING
■ Gasoline and its vapors are extremely flamma‐
ble. Your STIHL trimmer / brushcutter uses an
oil-gasoline mixture for fuel. If spilled and igni‐
ted by a spark or other ignition source, it can
cause fire and serious burn injury or property
damage.

5 IMPORTANT SAFETY INSTRUCTIONS
► Use extreme caution when han‐
dling gasoline or fuel mix.
► Do not smoke or bring any fire or
flame near the fuel or the trim‐
mer / brushcutter.
► 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:
► Always place the power tool on
the ground before attempting to
fuel the machine.
► Fuel your trimmer / brushcutter 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 trimmer / brushcut‐
ter.
► Take care not to get fuel on your
clothing. If this happens, change
your clothing immediately.
Allow the Engine 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 cylin‐
der and engine temperatures will rise for sev‐
eral 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 trimmer / brushcutter 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.
