1.4 DC FUSES
These fuses are located inside the control panel. They protect the
panel wiring and components from damaging overload. The unit
will not start or crank if a fuse is blown. Replace the fuses with the
same size, type, and rating.
1.5 FUEL SYSTEM
1.5.1 FUEL REQUIREMENTS
NOTE:
It is the responsibility of the installer to make sure that only
the correct recommended fuel is supplied to the generator fuel
system. Thereafter, the owner/operator must make certain that
only the proper fuel is supplied.
For further information on the various types of fuel systems,
refer to Engine-Generator Standby Electric Power Systems
Installer’s Guide and Reference Manual (part #046622).
1.5.2 DIESEL FUEL SYSTEM
Diesel fuel is supplied to the generator set from a base-mounted
fuel tank.
Diesel fuels are less volatile than gaseous fuels, however, careless
installation can lead to safety hazards and/or serious problems
with engine/generator performance and reliability.
NOTE:
Appropriate care should be taken in applications where
extremely low ambient temperatures are possible to ensure the
temperature of the diesel fuel is not allowed to fall below levels
where “gelling” could occur.

1.6.3 ENGINE OIL RECOMMENDATIONS
The unit has been filled with 15W-40 engine oil at the factory. Use
a high-quality detergent oil classified “For Service CC, SD, SE or
SF.” Detergent oils keep the engine cleaner and reduce carbon
deposits. Use oil having the following SAE viscosity rating, based
on the ambient temperature range anticipated before the next oil
change:
Temperature Oil Grade (Recommended)
Above 80º F (27º C) SAE 30W or 15W-40
32º to 80º F (-1º to 27º C) SAE 20W-20 or 15W-40
Below 32º F (0º C) SAE 10W or 15W-40
