4.8.4 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.
5.1
FUSE
The generator panel's 15 amp fuse (Figure 5.1) 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, battery charging will not be pos-
sible. Replace the fuse using only an identical 5 amp
replacement. To remove fuse, push cap down and
rotate counterclockwise.

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.

5.3.1 ENGINE OIL RECOMMENDATIONS
d e a le r a t :
Use all season SAE 5W-30 synthetic oil or use SAE
30 oil of American Petroleum Institute (API) Service
Class SG, SH, SJ or SL.
Any attempt to crank or start the engine before
S E N S E
it has been properly serviced with the recom-
mended oil may result in an engine failure.
5.3.2 OIL CHANGE PROCEDURE
To change the oil, proceed as follows:
1. Run the engine until it is thoroughly warmed up
then shut OFF the engine.
2. Immediately after the engine shuts OFF , pull the
oil drain hose (Figure 5.3) free of its retaining
clip. Remove the cap from the hose and drain the
oil into a suitable container.
