15 kW Generator
3.7.3 OVERCRANK
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 will light indicating an overcrank failure. The AUTO/OFF/ MANUAL switch will need to be set to OFF and then back to AUTO to reset the generator control board.
NOTE:
If the fault is not repaired, the overcrank feature will continue to activate.

4.2CHECKING THE ENGINE
OIL LEVEL
For oil capacities, see the “Specifications,” Section. For engine oil recommendations, see Section 4.3.1. To check the engine oil level, proceed as follows (Figure 4.2):
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.
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 genera- tor from supplying an output that could potentially damage appliances connected to the generator cir- cuit. Contact the nearest dealer if this failure occurs.
4.1FUSES
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, the engine cannot crank or start. Replace the fuse using only an identical
The generator panel’s 7.5 amp fuse protects the 12 VDC accessory socket. If the fuse element has melted open, the 12 VDC socket will not provide power to any accessories. Replace the fuse using only an iden- tical 7.5 amp replacement. To remove fuse, push the fuse holder cap down and rotate counterclockwise.
