GROUND FAULT PROTECTION
The generator is equipped with a 120 volt duplex recep-
tacle, and a 120V locking type receptacle. Each of these
receptacles incorporates a Ground Fault Circuit
Interrupter (GFCI) rated at 20 amps. These devices
meet standards with applicable federal, state and local
codes.
The GFCI protects you against electrical shock that may
be caused if your body becomes a path through which
electricity travels to reach ground. This could happen if
you touch an appliance or cord that is "live." You don't
even have to be on the ground, you could be touching
plumbing or other material that leads to ground.
When protected by a GFCI, a person will still feel a
shock, but the GFCI should cut it off quickly enough so
a person in normal health should not have a serious
electrical injury (Infants and very small children could
still be affected).
WARNING! THE GFCI WILL NOT PROTECT YOU
AGAINST THE FOLLOWING SITUATIONS: (1) LINE-
TO-LINE SHOCKS (such as shocks from touching
metal in both straight slots of an outlet); (2)
CURRENT OVERLOADS OR LINE-TO-LINE SHORT
CIRCUITS. THE FUSE OR CIRCUIT BREAKER AT
THE DISTRIBUTION PANEL MUST PROVIDE SUCH
PROTECTION.
Testing the GFCI: Test your GFCI outlets every month.
Follow these instructions:
1.Push the black TEST button. Red RESET button
should pop out from inner surface, which should
allow no power to reach the outlet. Use a test lamp
in each outlet.
CAUTION! If RESET button does not pop out or
test lamp remains lit when RESET button does
pop out, DO NOT USE ANY OUTLETS ON THE
CIRCUIT. CALL A QUALIFIED ELECTRICIAN.
2.If the GFCI tests good, restore power by pressing
the RED RESET button. THE RESET BUTTON
MUST BE PUSHED FIRMLY AND FULLY INTO
PLACE UNTIL IT LOCKS AND REMAINS IN THAT
POSITION. IF THE GFCI DOES NOT RESET PROP-
ERLY, DO NOT USE THE OUTLET — CALL A
QUALIFIED ELECTRICIAN. Test lamp should go
ON.
3.If the GFCI trips by itself at any time during or after
installation, reset and perform steps 1 and 2. IF
RESET BUTTON DOES NOT POP OUT WHEN
TEST BUTTON IS PRESSED, DO NOT USE THE
OUTLET. CALL A QUALIFIED ELECTRICIAN.
NOTE: Each 120 volt receptacle is protected with
a 15 amp circuit breaker. The maximum total cur-
rent from each receptacle is limited to 15 amps

MAINTENANCE
It is the owner's responsibility to perform all safety
checks; to verify all required maintenance is performed
for safe operation; and to have the equipment checked
periodically by an authorized service technician.
Normal maintenance service and replacement of parts
are the responsibility of the owner/operator and, as
such, are not considered defects in workmanship or
material under the terms of the warranty.
Individual operating habits and equipment usage con-
tribute to the need for maintenance service. Proper
maintenance and care of your generator will help keep
the number of problems and overall operating expenses
at a minimum. See your authorized Generac Power
Systems dealer/distributor or contact the factory for
service aids.
100-HOUR BREAK IN
The first 100 hours is the break in period. Correctly
breaking in the engine-generator is essential to mini-
mize oil consumption and maximize engine perform-
ance. During break in, observe the following rules.
• For the 100 hours of operation, avoid light electrical
loads. Load the unit at 50% or more of its capacity
during this period. Repeated light loads during
break in can cause improper seating of the engine
piston rings, resulting in blowby and high oil con-
sumption after prescribed break in period.
• Check engine oil level frequently during break in. It
is normal for oil consumption to be higher than
normal during this period. The proper break in oil
is John Deere's P/N TY22014.
• After the 100-hour break in, complete the tasks rec-
ommended under "100-Hour Break In Period".
• If continuous light loads are applied to unit during
break in period, run unit for another 100 hour
break in period with the recommended engine oil.
100-HOUR BREAK IN PERIOD
After the first 100 hours of operation, contact an
authorized service facility for the following mainte-
nance. The generator owner is responsible for all
charges.
• Change engine oil and filter.
• Check all fluid levels.
• During break in, don't add oil until level is at the
bottom of the crosshatching on dip stick.
• Inspect cooling system hoses for leaks, loose or
defective clamps, and for damage or deterioration.
• Check the fuel system for leaks, condition, and
tightness of fuel lines.
• Check the engine for proper operation.
Duplex
• Check generator AC output. Make sure voltage and
frequency are correct.
