‹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 gen- erator from supplying an output that could poten- tially damage appliances connected to the generator circuit. Contact the nearest Authorized Dealer if this failure occurs.

4.1FUSES

The generator panel's 15-amp fuse (Figure 4.1) pro- tects the DC control circuit and the battery charge circuit against overload. This fuse is wired in series with the battery output lead to the panel. If this fuse element has melted open, the engine will not be able to crank or start. The generator will also lose all bat- tery charge capabilities. Replace this fuse using only an identical 15-amp replacement fuse. To replace the fuse, push the fuse holder cap down and rotate it counterclockwise.

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 be able to provide power to any accessories. Replace this fuse using only an identical 7.5-amp replacement fuse. To replace the fuse, push the fuse holder cap down and rotate it counterclockwise.

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 origi- nal position.

OIL LEVEL

For oil capacities, see “Specifications,” Section 1.5. For engine oil recommendations, see Section 4.3.1. To check the engine oil level, proceed as follows (Figures 4.2 and 4.3):

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.
