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 gener-
ator from supplying an output that could potentially
damage appliances connected to the generator cir-
cuit. Contact the nearest Generac Authorized Dealer
if this failure occurs.
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, 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 possible.
Replace the fuse using only an identical 5 amp replace-
ment. To remove fuse, push cap down and rotate coun-
terclockwise.

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.
