Generator Control and Operation

Operation

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 along 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.

ACAUTIONI

AUse 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 befol'eoperating 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"

Check the oil level in the generator gearbox (if so equipped) prior to initial use and at the intervals indicated by the" Service Schedule." The recommended oil is SAE 90 gear lubricant

Also, if the engine is equipped with a mechanical governor, make sure the governor is properly lubricated with clean engine oil.

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 aforce of approximately 22 pounds (10 kg), applied midway between pulleys, deflects the belt about 3/8- to 5/8-inch (10 to 16 mm). This does not apply to automatic belt tensioning systems.

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 are properly installed in the tie-down holes in the side rails of the unit'sbase 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 generator set On acoustic units, cap plugs also are needed to stay within noise specification limits.

STA8r-UP INSPECTION

Astandard form titled "Start-up Inspection for Stationary Emergency 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 technician performing the install should then scan and e-mail the completed form to service@generac.com. The form can also be filled out at a dealer'sGenerac website.

Refer to the appropriate control panel operator'smanual for this unit

OPERATING UNIT WITH MANUAL TRANSFER SWITCH

If the generator was installed in conjunction with atransfer switch capable of manual operation only, the following procedure applies. A manually operated transfer switch is one that will not provide automatic start-up and does not include an intelligence circuit

For additional information, refer to the applicable control panel manual for this unit, as well as any literature pertaining to the transfer switch.
