Generac Power Systems 04456-1 Checking the Engine OIL Level, Approximate Crank Cycle Times

Section 4 — Maintenance

Guardian Air-cooled 7 kW, 12 kW and 15 kW Generators

NOTE:

If the fault is not repaired, the overcrank feature will continue to activate.

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.

3.7.3.1 Approximate Crank Cycle Times

•15 seconds ON

•7 seconds OFF

•7 seconds ON

•7 seconds OFF

•Repeat for 45 seconds Approximately 90 seconds total

‹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 circuit. Contact the nearest Generac/Guardian Authorized Dealer if this failure occurs.

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.

4.1 FUSE	Oil Dipstick and Fill
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 15-amp replacement.

The generator panel’s 5 amp fuse protects the battery charge circuit against overload. If the fuse element has melted open, there will not be battery charging capabilities. Replace the fuse using only an identical 5 amp replacement. To remove fuse, push cap down and rotate counterclockwise.
