4.1 FUSE
The 7.5 amp fuse on the control panel protects the DC control
circuit against overload (Figures 3.1 and 3.2). This fuse is wired
in series with the battery output lead to the panel. If this fuse ele-
ment has melted open, the engine will not be able to crank or start.
Replace this fuse using only an identical 7.5 amp replacement
fuse. Whenever the fuse is removed or replaced, the exercise timer
needs to be reset.
4.2 CHECKING THE ENGINE OIL
LEVEL
For oil capacities, see the Specifications section. For engine oil
recommendations, see the Engine Oil Recommendations section.
When low battery levels necessitate running the generator for
extended periods of time, the oil level should be checked weekly.
To check the engine oil level, proceed as follows (Figures 4.1, 4.2
and 4.3):
1. If the generator is running, first turn OFF all associated loads
running in the residence. Second, turn the generator's main
circuit breaker to the OFF position.
2. Move the AUTO/OFF/MANUAL switch to the OFF position.
3. Remove the dipstick and wipe it dry with a clean cloth.
4. Completely insert the dipstick; then, remove it again. The oil
level should be at the dipstick “Full” mark. If necessary, add
oil to the “Full” mark only. DO NOT FILL ABOVE THE “FULL”
MARK.
5. Install the dipstick.
6. Reset the AUTO/OFF/MANUAL switch to its original position.
7. If the generator was running, first turn the generator's main
circuit breaker back to the ON position. Second, turn ON
needed loads in the residence.
* Repeat steps 3 through 5 for the oil reservoir.
n
Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.
NOTE:
When checking the oil level in the reservoir, it is normal that the
oil is steadily consumed, especially for the first 500 hours. At
the first service interval, the oil level in the reservoir will likely
be near the bottom of the dipstick. It is important that the engine
oil level remains within the limits of the dipstick.

4.3 CHANGING THE ENGINE OIL
n
Hot oil may cause burns. Allow engine to
cool before draining oil. Avoid prolonged
or repeated skin exposure with used oil.
Thoroughly wash exposed areas with soap.
4.3.1 OIL CHANGE INTERVALS
See the "Service Schedule" section.
4.3.2 ENGINE OIL RECOMMENDATIONS
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Synthetic
5W-30 is used under all conditions.
n
Any attempt to crank or start the engine
before it has been properly serviced with the
recommended oil may result in an engine
failure.
