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.

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.

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"
