Figure8-ControlModule Assembly Circuit Board
OVERCRANK SHUTDOWN:
After 90 seconds of crank-rest cycles, this function ends
cranking if the engine fails to start in that 90-second
span.
DC FUSE
This clearly labeled fuse is located on the front panel of
the control system. It protects the panel wiring and
components from damaging overload. Always remove
this fuse before commencing work on the generator.
The unit will not start or crank if the fuse is blown.
Replace the fuse with one of the same size, type, and rat-
ing. Generac normally uses an AGC fuse rated at 30
amps.
UNPACKING
UNPACKING PRECAUTIONS:
Handle shipping cartons and crates with care. Use care
to avoid damage from dropping, bumping, collision, etc.
Store and unpack cartons with the proper side up, as
noted on the shipping carton.
INSPECTION:
After unpacking, carefully inspect the generator for any
damage that may have occurred during shipment. If
loss or damage is noted at the time of delivery, have the
person(s) making delivery note all damage on the freight
bill or affix his signature under the consignor’s memo of
loss or damage.
LIFTING THE GENERATOR
WARNING: When lifting or hoisting equipment is used,
be careful not to touch overhead power lines. The
generators weight of more than 900 pounds requires
proper tools, equipment, and qualified personnel to be
used in all phases of handling and unpacking.
