PREPARATION BEFORE START-UP

The instructions in this section assume that the standby
generator has been properly installed, serviced, tested,
adjusted and otherwise prepared for use by a competent,
qualified installation contractor. Be sure to read the
"Safety Rules" on Pages 2 and 3, as well as all other safe-
ty information in this manual, before attempting to oper-
ate this (and related) equipment.
2.8.1 PRIOR TO INITIAL START-UP
Prior to initially starting the generator, it must be
!
properly prepared for use. Any attempt to crank
or start the engine before it has been properly
serviced with the recommended types and quanti-
ties of engine fluids (oil, coolant, fuel, etc.) may
result in an engine failure.
Before starting the generator for the first time, the
installer must complete the following procedures. For
follow-up maintenance information and/or service inter-
vals, please refer to Section 4, "Maintenance."
2.8.2 FUEL SYSTEM
Make sure the fuel supply system to the generator (a)
delivers the correct fuel at the correct pressure and (b)
is properly purged and leak tested according
to code. No fuel leakage is permitted. See Section 1.8,
"Specifications", for more information.
2.8.3 GENERATOR SET LUBRICATION
Check the engine crankcase oil level before operating
and add oil to the proper level – the dipstick "FULL "
mark. Never operate the engine with the oil level below
the dipstick "ADD"
"Specifications" and
Recommendations".
This engine is shipped from the manufacturer with
SAE 15W-40 oil. This oil should be changed after 30
hours of operation.
2.8.4 ENGINE COOLANT
Have the engine cooling system properly filled with the
recommended coolant mixture. Check the system for
leaks and other problems.
"Specifications" and Section 1.11, "Coolant".

Guardian Liquid-cooled 40 kW Generator
2.8.5 BELT TENSION
Check the engine fan belt tension and condition prior to
placing the unit into service and at recommended
intervals. Belt tension is correct when a force of approx-
imately 22 pounds (10 kg), applied midway between
pulleys, deflects the belt about 3/8- to 5/8-inch (10 to 16
mm).
2.8.6 ELECTRICAL SYSTEM
Make sure the generator is properly connected to an
approved earth ground and/or ground rod.
Make sure the generator battery is fully charged, proper-
ly installed and interconnected, and ready for use.
Check to ensure that there are no loose electrical con-
nections. Restrain any loose wires to keep them clear of
any moving generator set components.
2.8.7 RODENT PROTECTION
Make sure the four 3-inch diameter cap plugs (part #
0A8785) are properly installed in the tie-down holes in
the side rails of the unit's base frame (Figure 2.3). The
cap plugs are shipped in a plastic bag located in the
lower connection box. These plugs are needed to pre-
vent rodents from accessing the interior of the genera-
tor set. On acoustic units, cap plugs also are needed to
stay within noise specification limits.
