Air Conditioning Operation
For best results, the Smart Throttle switch should be in the off position. Bring the generator to normal
operating temperatures before applying the air conditioning load. Always allow a 2 minute wait period
when manually cycling an air conditioner off and on. A longer wait period may be required under
unusually hot weather conditions. Additionally, all other loads should be turned off until the air
conditioner has started and is performing normally. It is also important to follow the air conditioner
manufacturer's instructions for starting and restarting for proper operation. Some air conditioner
manufacturers offer a start capacitor or rapid start kit as an extra cost option. The lack of a start
capacitor can cause the air conditioner to draw too high a starting current and overload the
generators. Contact your air conditioner dealer if you consistently have problems starting your air
conditioner with the generators in parallel.
Smart Throttle System
When the Smart Throttle switch is placed in the ON position, engine speed is controlled to match the
electrical load. The engine will idle at no load and will increase speed as more load is applied.

The Smart Throttle system does not operate effectively if the
electrical appliance requires constant fluctuations in power.

When high electrical loads are connected simultaneously, turn the
Smart Throttle switch to the OFF position to reduce voltage
fluctuation or shutdown.

In DC operation, turn the Smart Throttle switch to the OFF position.
DC voltage may be too low when the Smart Throttle is ON.
When the Smart Throttle switch is placed in the OFF position, the engine throttle is fixed at maximum
speed, improving the ability of the generator to accept large or fluctuating loads.
High Altitude Operation
The reduced oxygen available at higher altitudes will reduce the maximum power available from the
engine. High altitude performance can be improved somewhat by installing a special high-altitude jet
in the carburetor. If you operate the generator at altitudes higher than about 5000 feet above sea
level for extended periods, have your authorized dealer install a high altitude main jet.
Even with suitable carburetor jetting, engine horsepower will decrease approximately 3.5% for each
1000 feet or 305 meter increase in altitude. The effect of altitude on the horsepower will be greater
than this if the carburetor is not re-jetted.
Be sure to restore the original jet before operating at lower elevation or engine damage due to an
excessively lean fuel mixture may occur.
Ambient Temperature
Generator power generally degrades 1% for every 10° F (5.5° C) above 85° F (29° C). The normal
operating range of the generator is -20° to 113° F (-29° to 45° C).
Do not operate the generator when the ambient temperature is above 113° F (45° C)
