4.1 FUSE
The generator panel’s 15 amp fuse (Figure 4.1) protects
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, you cannot crank
or start the engine. You should 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, you will not have battery charging capa-
bility. You should replace the fuse using only an identi-
cal 5 amp replacement. To remove fuse, push cap down
and rotate counterclockwise.

4.2 CHECKING THE ENGINE
OIL LEVEL
For oil capacities, see “Specifications,” Section 1.5
(Page 6). 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.
4. Install the dipstick.
5. Reset the Auto/Off/Manual switch to its original
position.

4.3 CHANGING THE ENGINE OIL
4.3.1 ENGINE OIL RECOMMENDATIONS
Use oil of American Petroleum Institute (API) Service
Class SG, SH or SJ. Use all season SAE 5W-30
Synthetic oil. Organic break-in oil is required before
using synthetic oil.
NOTE:
The unit is supplied with “break-in” oil. See the
“Break-in Procedure,” Section 3.1 (Page 12), for
the first required oil change.
Any attempt to crank or start the engine before
it has been properly serviced with the recom-
mended oil may result in an engine failure.
