Connect devices to be powered by generator by following the steps below
(see pages 8-10).
•
Make sure the generator can supply enough continuous (running) and surge (starting) watts for the items you
will power at the same time. See page 9 for how to calculate total amount of power needed.
•
Start the generator with nothing connected.
•
Plug in and turn on the first load, preferably the largest load you have.
•
Permit the generator output to stabilize (engine runs smoothly and attached device operates properly).
•
Plug in and turn on the next load.
•
Again, permit the generator to stabilize.
•
Repeat previous two steps for each additional load.
IMPORTANT: Never add more loads than the generator capacity. Take special care to consider surge loads in
generator capacity.

WARNING:
Do not connect to a building’s electrical
system unless the generator and transfer
switch have been properly installed and
the electrical output has been verified by
a qualified electrician. The connection
must isolate the generator power from
utility power and must comply with all
applicable laws and electrical codes.
IMPORTANT!
CHOKE LEVER

PROBLEM
POSSIBLE CAUSE
SOLUTION
Engine will not start.
No fuel.
Stale gasoline or water in gasoline.
Lubricant level is low.
Fuel valve is OFF.
Spark plug faulty, fouled, or improperly
gapped.
Choke lever is in RUN position.
Engine stored without treating or draining
gasoline, or refueled with bad gasoline.
Dirty fuel filter.
CO sensor LED is flashing red, indicating
a CO hazard.
CO sensor LED is flashing yellow and/
or making an audible chirp, indicating a
sensor fault.
Fill fuel tank.
Drain entire system and refill with fresh fuel.
Engine is equipped with Low Oil Shutoff. If engine
lubricant level is low, it must be filled before unit
will start. Check engine lubricant level and fill, if
necessary.
Turn fuel valve ON.
Replace spark plug.
Move choke lever to START position.
Drain fuel and carburetor. Refuel with fresh gasoline.
Replace fuel filter or contact a qualified service center.
Leave area immediately and relocate to an open
outdoor area. Ventilate area thoroughly before oc-
cupying again. Ensure the generator is located in
an open outdoor area at least 20 feet away from all
doors, windows, and occupied spaces, and point
exhaust away from occupied structures.
The CO sensor needs to be repaired or replaced.
Contact customer service or a qualified service
center for assistance.
Engine hard to start.
Water in gasoline.
Weak spark at spark plug.
Drain entire system and refill with fresh fuel.
Replace spark plug or contact a qualified service
center.
Engine lacks power.
Air filter element is clogged.
Engine stored without treating or draining
gasoline, or refueled with bad gasoline.
Check air filter element. Clean or replace as needed.
Drain fuel and carburetor. Refuel with fresh gasoline.
If problem continues, contact a qualified service
center.
AC receptacle does not work. Circuit breaker is tripped.
GFCI is tripped.
Item plugged in is defective.
Reset the AC circuit breaker.
Reset the GFCI.
Try a different item.
Generator makes a “spark
knock” or “pinging” noise.
An occasional light “knocking” or “ping-
ing” under heavy load is not a cause for
concern. However, if the knocking or
pinging occurs under normal load at a
steady engine speed, the problem may
be with the brand of gasoline being used.
Switch to a different brand of gasoline, making sure
that the octane rating is 86 or higher. If problem
continues, contact a qualified service center.
If problem persists after trying the above solutions, contact customer service or a qualified service center for assistance.
