3.3.4 HIGH ALTITUDE OPERATION
The fuel system on this generator may be influenced by operation
at higher 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.
Unit Fuel
5.5kW-7.5kW Gasoline
* Elevation above sea level
** At elevations above 8000 ft, the engine may experience decreased
performance
3.4 GENERAL RECOMMENDATIONS
The warranty of the generator does not cover items that have been
subjected to operator abuse or negligence. To receive full value
from the warranty, the operator must maintain the generator as
instructed in this manual.
Some adjustments will need to be made periodically to properly
maintain the generator.
All adjustments in the Maintenance section of this manual should
be made at least once each season. Follow the requirements in the
"Maintenance Schedule".
Clean the air filter every 20 hours. Once a year replace the
spark plug and replace the air filter. A new spark plug and clean
air filter assure proper fuel-air mixture and help the engine run
better and last longer.
3.4.1 GENERATOR MAINTENANCE
Generator maintenance consists of keeping the unit clean and dry.
Operate and store the unit in a clean dry environment where it will
not be exposed to excessive dust, dirt, moisture or any corrosive
vapors. Cooling air slots in the generator must not become clogged
with snow, leaves, or any other foreign material.
Check the cleanliness of the generator frequently and clean when
dust, dirt, oil, moisture or other foreign substances are visible on
its exterior surface.
Never insert any object or tool through the air

cooling slots, even if the engine is not running.

6000 – 8000 ft** 0J6613B
NOTE:
DO NOT use a garden hose to clean generator. Water can enter
the engine fuel system and cause problems. In addition, if water
enters the generator through cooling air slots, some water will
be retained in voids and crevices of the rotor and stator winding
insulation. Water and dirt buildup on the generator internal
windings will eventually decrease the insulation resistance of
these windings.
3.4.2 TO CLEAN THE GENERATOR
• Use a damp cloth to wipe exterior surfaces clean.
• A soft, bristle brush may be used to loosen caked on dirt, oil,
etc.
• A vacuum cleaner may be used to pick up loose dirt and debris.
• Low pressure air (not to exceed 25 psi) may be used to
blow away dirt. Inspect cooling air slots and openings on the
generator. These openings must be kept clean and unobstructed.
3.4.3 ENGINE MAINTENANCE
When working on the generator, always

disconnect negative cable from battery. Also
disconnect spark plug wire from spark plug and
keep wire away from spark plug.
3.4.4 CHECKING OIL LEVEL
See the "Before Starting the Generator" section for information on
checking the oil level. The oil level should be checked before each
use, or at least every eight hours of operation. Keep the oil level
maintained.
3.4.5 CHANGING THE OIL
Change the oil after the first 30 hours of operation. Change the
oil every 100 hours or every season thereafter. If running this
unit under dirty or dusty conditions, or in extremely hot weather,
change the oil more often.
Hot oil may cause burns. Allow engine to

cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
Use the following instructions to change the oil after the engine
cools down:
• Clean area around oil drain plug.
• Remove oil drain plug from engine and oil fill plug to drain oil
completely into a suitable container.
• When oil has completely drained, install oil drain plug and
tighten securely.
• Fill oil sump with recommended oil. (See "Before Starting the
Generator" for oil recommendations).
• Wipe up any spilled oil.
• Dispose of used oil at a proper collection center.
