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.

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
Use oil that meets the American Petroleum Institute
(API) classification of SC, SD, SE, SF, SG, SH, or SJ.
Using unsuitable oil or neglecting an oil change may
result in engine damage that is not covered by the
engine warranty. Figure 2-1 shows the recommended
Society of Automotive Engineers (SAE) viscosity
designation for given operating temperature ranges.
Do not mix different oil brands. Incompatibility could
cause a breakdown of lubricating ingredients and
reduce engine protection.
