PREPARATION BEFORE START-UP
The instructions in this section assume that the Stationary
Emergency 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 safety information in this manual,
before attempting to operate this (and related) equipment.
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 rec-
ommended types and quantities 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 intervals, please refer to Section 4,
“Maintenance,” and the “Service Schedule”.
Transfer Switch
If this generator is used to supply power to any electrical system
normally powered by an electric utility, the National Electrical Code
requires that a transfer switch be installed. The transfer switch pre-
vents electrical backfeed between two different electrical systems.
(For additional information, see the applicable transfer switch
manual for this unit.) The transfer switch, as well as the alternator
and other generator components, must be properly located and
mounted in strict compliance with applicable codes, standards
and regulations.
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
“Specifications” for more information.
If the unit has been idle for a long period of time, or if the fuel lines
or system components have been removed and reinstalled, the fuel
system may require bleeding to remove air from the system. Air in
the fuel system causes hard starting and rough operation. All fuel
system lines must be installed and must be tight. A loose line may
show no sign of leakage, but may draw air into the system.
Stationary Emergency Generator 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” mark. See
“Specifications” and “Engine Oil Recommendations”.
NOTE:
This engine is shipped from the manufacturer with 15W-40 oil.
This oil should be changed after 30 hours of operation.
Engine Coolant
Have the engine cooling system properly filled with the recom-
mended coolant mixture. Check the system for leaks and other
problems. See “Specifications” and “Coolant”.
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 approximately 22 pounds (10 kg), applied
midway between pulleys, deflects the belt about 3/8- to 5/8-inch
(10 to 16 mm).
Electrical System
Make sure the generator is properly connected to an approved
earth ground.
Make sure the generator battery is fully charged, properly installed
and interconnected, and ready for use.
Check to ensure that there are no loose electrical connections.
Restrain any loose wires to keep them clear of any moving genera-
tor set components.
Rodent Protection
Make sure the four, 3-inch diameter cap plugs (part no. 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 prevent rodents from accessing the interior of the gen-
erator set. On acoustic units, cap plugs also are needed to stay
within noise specification limits.

START-UP INSPECTION
A standard three-part form titled “Start-up Inspection for Standby
Power Systems” (part no. 067377) should be completed by the
installation technician or engineer. As stated on the form, inspec-
tions are to be accomplished only by factory-trained personnel.
The installer should complete the form and disseminate copies
as follows:
• White copy: Mail to Generac Warranty Department, P.O. Box 8,
Waukesha, WI 53187.
• Pink Copy: For service file of installing dealer.
• Yellow Copy: For the customer’s records.
