without allowing the power tool to cool
adequately. It is more likely to occur
when the fuel tank is half full or more.
Pressure is caused by fuel and heat and
can occur even if the engine has not
been running. When gasoline in the fuel
tank is heated (by ambient
temperatures, heat from the engine, or
other sources), vapor pressure will
increase inside the fuel tank.
Some blends of gasoline, particularly
those designed for use in winter, are
more volatile and may cause tanks to
pressurize more quickly or create
greater pressure. At higher altitudes,
fuel tank pressurization is more likely.
How to Avoid Fuel Spraying
Removing the fuel cap on a pressurized
tank can result in gasoline, vapors and
fumes being forcefully sprayed out from
the fuel tank in all directions. To reduce
the risk of burns, serious injuries or
property damage from fuel spraying:
– Follow the fueling instructions in this
chapter.
– Always assume your fuel tank is
pressurized.
– Allow the power tool to cool before
removing the fuel cap.
– In hot environments, cooling will
take longer.
– The engine is air cooled. When it is
shut off, cooling air is no longer
drawn across the cylinder and the
engine temperature will rise for
several minutes before starting to
cool.
After the power tool has cooled
appropriately, follow the safety
instructions in this chapter for removing
the cap. Never remove the cap by
turning it directly to the open position.
First check for residual pressure by
turning the cap slowly to the vent
position, approximately 1/8 turn counter-
clockwise. Use only good quality fuel
that is appropriate for the season
(summer v. winter blends). Some
blends of gasoline, particularly winter
blends, are more volatile and can
contribute to fuel spraying.
Removing the Toolless Fuel Cap: Turn
Slowly and Stop in the Vent Position
WARNING
After allowing the power tool to cool,
remove the fuel filler cap slowly and
carefully to allow any remaining
pressure build-up in the tank to release:
– Flip up the grip and press the cap
down firmly (1).
– While maintaining steady,
downward pressure, turn the cap
slowly counter-clockwise to the vent
position (2), approximately a
1/8 turn of the cap.
– If any significant venting occurs,
immediately re-seal the tank by
turning the cap clockwise to the
closed position. Allow the power
tool to cool further before attempting
to open the tank.
– Turn the cap to the open position (3)
only after the contents of the tank
are no longer under pressure. In the
open position, the exterior
positioning mark (4) on the cap will
line up with the "unlocked"
symbol (5) on the fuel tank housing.
– Never remove the cap by turning it
directly to the open position. First
allow the power tool to cool
adequately and then release any
residual pressure at the vent
position (2).
– Never attempt to remove the cap
while the engine is still hot or
running.
