fl ammable and explosive. Always handle
fuel with extreme care.
Failure to observe these safety
instructions can cause a fi re or
explosion which will result in severe
burns or death.
WHEN ADDING FUEL
Turn off engine and let cool at least 2 minutes before removing the fuel •
cap and adding fuel.
Fill fuel tank outdoors or in a well ventilated area.•
Do not overfi ll the fuel tank. To allow for the expansion of gasoline, do •
not fi ll above the bottom of the fuel tank neck.
Keep fuel away from sparks, open fl ames, pilot lights, heat, and other •
ignition sources.
Check fuel lines, cap, and fi ttings frequently for cracks or leaks. Replace •
if necessary.
Use an approved fuel container.•
If fuel spills, wait until it evaporates before starting engine.•
WHEN STARTING ENGINE
Ensure that spark plug, muffl er, fuel cap, and air cleaner (if equipped) •
are in place and secured.
Do not crank the engine with the spark plug removed.•
If fuel is spilled, do not attempt to start the engine, but move the snow •
thrower away from the area of the spill, and avoid creating any source of
ignition, until the fuel vapors have dissipated.
Do not over-prime the engine. Follow the engine starting instructions in •
this manual.
If the engine fl oods, set choke (if equipped) to OPEN/RUN position, •
move throttle (if equipped) to FAST position and crank until engine
starts.
