Section 2 Scheduled Maintenance
2.1 General
Accidental starting.
Can cause severe injury or death.
Disconnect the battery cables before
working on the generator set.
Remove the negative (--) lead first
when disconnecting the battery.
Reconnect the negative (--) lead last
when reconnecting the battery.
WARNING
Disabling the generator set. Accidental starting can
cause severe injury or death. Before working on the
generator set or equipment connected to the set, disable the
generator set as follows: (1) Place the generator set start/stop
switch in the STOP position. (2) Disconnect the power to the
battery charger, if equipped. (3) Remove the battery cables,
negative (--) lead first. Reconnect the negative (--) lead last
when reconnecting the battery. Follow these precautions to
prevent the starting of the generator set by the remote
start/stop switch.
Rotating parts.
Can cause severe injury or death.
Operate the generator set only when
all guards, screens, and covers are in
place.
WARNING
Servicing the generator set when it is operating. Exposed
moving parts can cause severe injury or death. Keep
hands, feet, hair, clothing, and test leads away from the belts
and pulleys when the generator set is running. Replace
guards, screens, and covers before operating the generator
set.
Sound shield removal. Exposed moving parts can cause
severe injury or death. The generator set must be operating
in order to perform some scheduled maintenance procedures.
Be especially careful if the sound shield has been removed,
leaving the belts and pulleys exposed.
(Sound-shield-equipped models only)
NOTICE
Saltwater damage. Saltwater quickly deteriorates metals.
Wipe up saltwater on and around the generator set and
remove salt deposits from metal surfaces.
Note: See the generator set operation manual for the
service schedule and other service not included
in this manual.
2.2 Lubrication System
The following paragraphs describe the engine
lubrication system.
Use oil that meets the American Petroleum Institute
(API) classification of CD, CC/CD, or CC. Using
unsuitable oil or neglecting an oil change may result in
damage and a shorter engine life. Figure 2-1 shows the
recommended Society of Automotive Engineers (SAE)
viscosity designation for given operating temperature
ranges.
Note: Failure to observe these standards may cause
inadequate lubrication/oil pressure and cold-
starting difficulties.
