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.
Use a suitable container to catch the fuel
that will spill during system bleeding pro-
cess. Clean up all spilled fuel after bleeding.
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" mark. See
"Specifications" and "Engine Oil Recommendations" sections.
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 the "Specifications" and "Coolant" sections.
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.
NOTE:
Rodent Protection
Make sure the four, three-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 2.4). 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 generator set. On acoustic units, cap plugs also are needed to
stay within noise specification limits.

2.9.2 START-UP INSPECTION
A standard three-part form titled "Start-up Inspection for Standby
Power Systems" (part # 067377) should be completed by an
Authorized Service Dealer. As stated on the form, inspections are
to be completed only by factory-trained personnel. The installer
should complete the form and disperse copies as follows:
• White copy: Mail to Generac Warranty Department, P .O. Box
425, Whitewater, WI 53190.
• Pink Copy: For service file of installing dealer.
• Yellow Copy: For the customer's records.

OPERATING UNIT WITH
AUTOMATIC TRANSFER
SWITCH
If the generator has been installed along with an automatic transfer
switch, such as a GTS-type switch, the engine may be started and
stopped automatically or manually.
Refer to the applicable manual for the transfer switch and to
"Transfer Switch Start Signal Connections" section. In addition,
please note the dangers under "Engine Start-up and Transfer."
