3.7.3 OVERCRANK | Figure 4.1 – Generator Control Panel |
This feature prevents the generator from damaging itself when it continually attempts to start and anoth- er problem, such as no fuel supply, prevents it from starting. The unit will crank and rest for a preset time limit. Then, it will stop cranking, and the LED on the generator control panel will light indicating an over- crank failure. The Auto/Off/Manual switch will need to be set to OFF and then back to AUTO to reset the generator control board.

3.7.4 OVERSPEED
This feature protects the generator from damage by shutting it down if it happens to run faster than the preset limit. This protection also prevents the gener- ator from supplying an output that could potentially damage appliances connected to the generator cir- cuit. Contact your nearest Generac Authorized Dealer if this failure occurs.
4.1FUSE
The generator panel’s 15 amp fuse (Figure 4.1) pro- tects the DC control circuit against overload. The fuse is wired in series with the battery output lead to the panel. If the fuse element has melted open, you can- not crank or start the engine. You should replace the fuse using only an identical
The generator panel’s 5 amp fuse protects the battery charge circuit against overload. If the fuse element has melted open, you will not have battery charging capability. You should replace the fuse using only an identical 5 amp replacement. To remove fuse, push cap down and rotate counterclockwise.
For oil capacities, see “Specifications,” Section 1.5 (Page 6). For engine oil recommendations, see Section 4.3.1. To check the engine oil level, proceed as follows (Figure 4.2, on page 17):
1.Start the generator by moving the Auto/ Off/Manual switch to the MANUAL position. Allow it to run for a short while and then shut it down by moving the switch to the OFF position.
2.Remove the dipstick and wipe it dry with a clean cloth.
3.Install the dipstick; then, remove it again. The oil level should be at the dipstick “Full” mark. If nec- essary, add oil to the “Full” mark only. 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.
4.Install the dipstick.
5.Reset the Auto/Off/Manual switch to its original position.
