MAINTENANCE
Follow maintenance schedule intervals, whichever occurs first according to use.
NOTE: Adverse conditions will require more frequent service. All required service and
adjustments should be performed each season as detailed in the following chart:
At Each Use
Check engine oil level
Every 25 Hours
Clean Air Filter**
Every 100 Hours or Every Season*
Change Oil ‡
Clean /Gap Spark Plug
Every 200 Hours or Every Season
Replace Air Filter
Replace Spark Plug
Check/Adjust Valve Clearance***
‡
Change Oil after first 30 hours of operation, then every
season.
* Change oil every month when operating under heavy load
or in high temperatures.
** Clean more often under dirty or dusty operating
conditions. Replace air filter parts if they cannot be
adequately cleaned.
*** Check valve clearance and adjust if necessary after first
50 hours of operation and every 300 hours thereafter.
PREVENTIVE MAINTENANCE
Dirt or debris can cause improper operation and equipment damage. Clean generator daily or
before each use. Keep area around and behind muffler free from combustible debris. Inspect all
cooling air openings on generator.
Use a damp cloth to wipe exterior surfaces clean.
Use a soft bristle brush to loosen caked on dirt, oil, etc.
Use a vacuum 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 generator to ensure they are clean and unobstructed.
NOTE
: DO NOT use a garden hose to clean generator. Water can enter the engine’s fuel
system and cause problems. If water enters the generator through the cooling air slots, some
water will be retained in voids and crevices of rotor and stator winding insulation. Water and dirt
buildup on generator internal windings will decrease insulation resistance of windings.
WARNING:
Do not insert any object through the air cooling slots. Generator can start at any
time and could result in death, serious injury and unit damage.
WARNING:
Disconnect spark plug wires when working on unit to avoid accidental start-up.
Failure to do so could result in death or serious injury.
