5 IMPORTANT SAFETY INSTRUCTIONS
￭ Some blends of gasoline, particularly winter blends, 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
WARNING
￭ 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 blower to cool before removing the fuel
cap.
– If you need to refuel before completing a job, turn off
the machine and allow the engine 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 blower 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 slowly turning
the cap approximately 1/2 turn counter-clockwise.
– The cap should be held in place by the threads while
allowing residual vapor/pressure to be relieved.
– Once any residual pressure has been relieved, turn
the cap until it can be removed from the tank
opening.
– 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 Threaded Fuel Filler Cap
WARNING
￭
￭ After allowing the blower to cool, remove the fuel filler cap
slowly and carefully to allow any remaining pressure build-
up in the tank to release:
– While maintaining steady, downward pressure,
slowly turn the cap approximately 1/2 turn counter-
clockwise.
– If any significant venting occurs, immediately re-seal
the tank by turning the cap clockwise to the closed
position. Allow the blower to cool further before
attempting to open the tank.
– Turn the cap to the open position only after the
contents of the tank are no longer under pressure.
– Never remove the cap by turning it directly to the
open position without first allowing the blower to cool
adequately and then releasing any residual pressure
by slowly turning it approximately 1/2 turn counter-
clockwise.
– Never attempt to remove the cap while the engine is
still hot or running.
