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.
4.1 FUSES
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.

4.2 CHECKING THE ENGINE
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.
‹ 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.
