◆2.8.4 OVERVOLTAGE PROTECTION

A solid-state voltage regulator (Figure 2.5) controls the generator’s AC output voltage. This regulator sup- plies an excitation current to the rotor. By regulating the rotor’s excitation current, the strength of its mag- netic field is regulated and, in turn, the voltage deliv- ered to connected electrical loads is controlled. When the AC frequency is 60 Hertz, voltage is regulated at 115 volts.

◆2.8.6 25-HOUR CHECK-UP

After the 25-hour break-in period, contact a Generac Authorized Service Dealer for the following mainte- nance. (The vehicle owner is responsible for any charges relating to normal unit maintenance.)

•Change the engine crankcase oil and oil filter.

•Check all fluid levels.

•Inspect the cooling and ventilation openings.

•Check the engine ignition system.

•Inspect the entire electrical system.

•Inspect the engine exhaust system.

The voltage regulator also incorporates a “voltage surge protection circuit.” This circuit prevents trou- blesome surges in the generator AC output voltage. Voltage surge is a common cause of damage to elec- tronic equipment.

◆2.8.5 25-HOUR BREAK-IN PERIOD

The first 25 hours of operation is the break-in period for the generator. Properly breaking in the generator is essential to minimize fuel consumption and pro- vide maximum engine performance. During this 25- hour break-in period, follow this procedure:

•Run the unit at varying electrical loads to help seat the engine piston rings properly.

•Check the engine oil level frequently. Add oil if needed. It is normal for the generator engine to consume more oil than is normal until the piston rings have properly seated.

•For the 75-hour operation following the break-in period, avoid light electrical loads. Load the generator at 50 percent (or more) of its rated wattage capacity. Repeated light loads during these 75 hours can cause improper seating of engine pis- ton rings, resulting in blowby and high oil con- sumption.

•After operating the unit for 25 hours, complete the tasks recommended under Section 2.8.6.

◆2.8.7 OPERATION IN HIGH GRASS OR BRUSH

Never operate the generator while the vehicle is parked over high grass, weeds, brush, leaves or any other combustible substance. Such materials can ignite and burn from the heat of the exhaust system. The generator exhaust system becomes extremely hot dur- ing operation and remains hot for a long time after it has shut down.

3.1CHECKING THE ENGINE OIL

LEVEL

For oil capacities and requirements, see “Engine Oil Requirements,” Section 1.6.2 (Page 6). Check the engine crankcase oil level at least every eight hours of operation, or before you use it. To check the engine oil level, proceed as follows (see Figure 3.1):

1.Be sure the generator is as level as possible.

2.Remove the dipstick and wipe it dry with a clean, lint-free cloth.

3.Install and tighten the dipstick cap; then, remove it again. The oil level should be at the dipstick “Full” mark.

4.If necessary, remove the oil fill cap on the rocker cover and slowly add oil until it reaches the dip- stick “Full” mark. DO NOT FILL ABOVE THE “FULL” MARK.

Never operate the engine with the oil level

!below the “Add” mark on the dipstick. Doing this could damage the engine.

5.Install and tighten the oil fill cap and the dipstick before operating the engine.
