MAINTENANCE
MaintEnanCE PrECautions
before performing maintenance
on the generator, review Safety on
page 7 and the following safety
messages.
!
WARNING
!
Avoid accidentally starting the
generator during maintenance
by removing the spark plug boot
from the spark plug. For electric
start generators, also disconnect
the battery cables from the battery
(disconnect the black negative (-)
cable first) and place the wires away
from the terminals to avoid arcing.
Allow hot components to cool to
the touch prior to performing any
maintenance procedure.
Internal pressure can build in the
engine crankcase while the engine
is running. Removing the oil fill plug/
dipstick while the engine is hot can
cause extremely hot oil to spray out of
the crankcase and severely burn skin.
Allow engine oil to cool for several
minutes before removing the oil fill
plug/dipstick.
Always perform maintenance in a well-
ventilated area. Fuel and fuel vapours
are extremely flammable and can
ignite under certain conditions.
!
CAUTION
Avoid skin contact with engine oil
or fuel. Prolonged skin contact with
engine oil or fuel can be harmful.
Frequent and prolonged contact with
engine oil may cause skin cancer.
Take protective measures and wear
protective clothing and equipment.
Wash all exposed skin with soap and
water.
Maintenance Schedule
!
WARNING
!
Failure to perform periodic
maintenance or not following
maintenance procedures can cause
the generator to malfunction and
could result in death or serious injury.
NOTICE
Periodic maintenance intervals vary depending
on generator operating conditions. Operating
the generator under severe conditions, such as
sustained high-load, high-temperature, or unusually
wet or dusty environments, will require more
frequent periodic maintenance. The intervals listed
in the maintenance schedule should be treated only
as a general minimum guideline. Use only genuine
Westinghouse spare parts or others as specified
herein. Non-genuine spare parts may be of inferior
quality and cause damage to the generator.
Following the maintenance schedule is essential to keep the generator in good operating condition. Table 1
provides a summary of routine inspection procedures and simple maintenance tasks that can be performed
by someone with mechanical competence using commonly available hand tools. Alternatively, an authorized
Westinghouse service dealer can carry out this work for a fee.
