Operation

2.8 COLD WEATHER OPERATION/DE-ICER

Under certain weather conditions (temperatures below 40° F (4°
C) and a high dew point), the engine may experience icing of the
carburetor and/or the crankcase breather system. To eliminate
this problem, this generator engine is fitted with a winter/summer
valve. This directs hot air into the carburetor during cold weather
operation. Always make sure the winter/summer valve is in the
correct location relative to the weather conditions.

the receptacles AND devices turned on.
• Unplug all electrical loads from the unit's receptacles before
starting the engine.
• Make sure the unit is in a level position.

If engine fires but does not continue to run, ensure choke
knob is in the "Full Choke" position and repeat starting
instructions.

2.10 HIGH ALTITUDE OPERATION

The fuel system on this generator may be influenced by operation
at high altitudes. Proper operation can be ensured by installing an
altitude kit when required. See the table below to determine when
an altitude kit is required. Operating this generator without the
proper altitude kit installed may increase the engine's emissions
and decrease fuel economy and performance. Kits may be
obtained from any Dealer, and should be installed by a qualified
individual.

** At elevations above 6500 ft, the engine may experience
decreased performance.
• Press and hold the Start/Run/Stop switch in the "Start"
position. The engine will crank and attempt to start. When the
engine starts, release the switch to the run position.
• When the engine starts, push choke knob to "1/2 Choke"
position until the engine runs smoothly and then fully in to the
"Run" position. If engine falters, pull choke knob back out to
"1/2 Choke" position until the engine runs smoothly and then
to "Run" position.

2.11 STOPPING THE ENGINE

• Shut off all loads, then unplug the electrical loads from
generator panel receptacles. Never start or stop the engine with
electrical devices plugged in and turned on.
