Maintenance
4.1 — Maintenance Schedule
The generator warranty does not cover damage due to
operator abuse, negligence, or neglect. To receive full
value from the warranty, the generator must be properly
maintained.
Periodic inspection and service is required to properly
maintain the generator. All maintenance tasks should be
performed at least once each season. More frequent ser-
vice is required when operating in adverse conditions.
To ensure safe and proper operation, and to maximize
service life, observe the maintenance tasks and intervals
shown in Table 4-1.

4.3.1— General
Operate and store the generator in a clean and dry envi-
ronment to avoid exposure to excessive dust, dirt, mois-
ture, or corrosive vapors. Verify that cooling air slots are
not clogged with snow, leaves, or other debris.
Check the cleanliness of the generator frequently and
clean when dust, dirt, oil, moisture or other foreign sub-
stances are visible on exterior surfaces.
Never insert any object or tool through the
air cooling slots, even if the engine is not
