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 gener-
ator from supplying an output that could potentially
damage appliances connected to the generator
circuit. Contact the nearest Generac/Guardian
Authorized Dealer if this failure occurs.
4.1

FUSE

The generator panel's 15 amp fuse (Figure 4.1) 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, there will not be battery charging
capabilities. Replace the fuse using only an identical
5 amp replacement. To remove fuse, push cap down
and rotate counterclockwise.

Section 4 — Maintenance
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.
