SECTION 7: OPERATION
GAS AND OIL FILL-UP
Service the engine with gasoline and oil as
instructed in the separate engine manual packed
with your snow thrower.
Read instructions
carefully.
WARNING:
Never fill fuel tank indoors,
with engine running or while engine is
hot. Do not smoke when filling fuel tank.
Electric Starter
WARNING:
The electric starter is equipped with
a three-wire power cord and plug, and is designed
to operate on 120 volt AC household current. It
must be properly grounded at all times to avoid the
possibility of electric shock which may be injurious
to the operator. Follow all instructions carefully.
Determine that your house wiring is a three-wire
grounded system. Ask a licensed electrician if you
are not certain. If your house wiring system is not a
three-wire grounded system, do not use this electric
starter under any conditions. If your system is
grounded and a three-hole receptacle is not
available at the point your starter will normally be
used, one should be installed by a licensed
electrician.
When connecting the power cord, always connect
cord to starter on engine first, then plug the other
end into a three-hole grounded receptacle.
When disconnecting the power cord, always unplug
the end from the three-hole grounded receptacle
first.
