3.6.3 PANEL
ORIENTATION
When replacing the panels after installation or maintenance, the
orientation of each panel is critical to proper cooling and operation
of the generator. Slide each panel into the corner post as identified
in Figure 3.6. Note the decals on each panel for the correct place-
ment, including the roof.

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.

CHECKING THE ENGINE OIL
LEVEL
For oil capacities, see the Specifications section. For engine oil
recommendations, see the Engine Oil Recommendations section.
When power outages necessitate running the generator for extend-
ed periods of time, the oil level should be checked daily.
To check the engine oil level, proceed as follows (Figures 4.1):
1. If the generator is running during a utility outage, 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 during a utility outage, first turn
the generator's main circuit breaker back to the ON position.
Second, turn ON needed loads in the residence.
n
Never operate the engine with the oil level
below the “Add” mark on the dipstick. Doing
this could damage the engine.

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.

ENGINE OIL RECOMMENDATIONS
All oil should meet minimum American Petroleum Institute (API)
Service Class SJ, SL or better. Use no special additives. Select
the oil's viscosity grade according to the expected operating tem-
perature.
