WARNING
Removing the cap on a pressurized fuel 
tank can result in gasoline, vapors and 
fumes being forcefully sprayed out from 
the tank in all directions. The escaping 
gasoline, vapors or fumes, sometimes 
referred to as fuel spraying or 
"geysering," can cause serious personal 
injury, including fire and burn injury, or 
property damage.
Fuel spraying can occur when the 
engine is hot and the tank is opened 
while under pressure. It can occur in hot 
environments even if the engine has not 
been running. Spraying is more likely to 
occur when the fuel tank is half full or 
more.
Avoid Injuries from Fuel Spraying.
Always follow the fueling instructions in 
this manual:
– Treat every fuel tank as if it is 
pressurized, particularly if it is half 
full or more.
– Always allow the power tool to cool 
adequately before attempting to 
open the fuel tank or refueling; this 
will take longer in hot conditions.
– Never remove the cap by turning it 
directly to the open position. Turn it 
first approximately 1/2 of a turn 
counter-clockwise to relieve any 
residual pressure.
– Never open the fuel tank while the 
engine is still hot or running.
– Never open the fuel tank or re-fuel 
the power tool near any sparks, 
flames or other ignition sources.
– Pick the right fuel: use only good 
quality (89 octane or higher), fresh 
fuel blended for the season.
– Vapor lock: do not remove the fuel 
cap in an effort to relieve vapor lock. 
Removing the cap has no effect on 
vapor lock.
– Be aware that fuel spraying is more 
likely at higher altitudes.
Preparations
N Before fueling, clean the filler cap 
and the area around it to ensure that 
no dirt falls into the tank.
N Position the machine so that the 
filler cap is facing up.
WARNING
In order to reduce the risk of fire and 
other personal injury from escaping gas 
vapor and fumes, remove the fuel filler 
cap slowly and carefully so as to allow 
any pressure build-up in the tank to 
release slowly.
Opening
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:
N While maintaining steady, 
downward pressure, slowly turn the 
cap approximately a 1/2 turn 
counter-clockwise.
N 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.
N Turn the cap to the open position 
only after the contents of the tank 
are no longer under pressure.
N Remove the fuel filler cap.
