Break-in Period
a. Breaking-in the Engine will help to ensure proper equipment and Engine operation.
b. The break-in period will last about 30 hours of use.
DO NOT exceed 75% of the Generator’s running wattage during this period.
• Change the engine oil after this period.
Under normal operating conditions subsequent maintenance follows
the schedule explained in the MAINTENANCE section.
Nominal 12VDC Output
1. Move the Economy (ESC) Switch to the OFF position.
2. Only use the 12 VDC receptacle to charge a 12 volt lead-acid type battery using an appropriate
charge controller. (Battery and controller not included.) The 12 VDC output is not regulated.
3. Do not connect any device to the 12 VDC terminal that draws more than 8 amps.
4. If this 12 VDC circuit protection is tripped, reduce the load, and press the Reset Button next to the outlet.
Note: Do not allow the Generator to completely run out of fuel with devices attached. A Generator’s
output may sharply spike as it runs out of fuel, causing damage to attached devices.
Connecting Electrical Loads
Familiarize yourself with the engine controls, power panel and how to start the engine
before using the Generator. Calculate the wattage of the products you will use with
the Generator and verify that the Generator can handle the total load.
WARNING! Connect only properly wired plugs to the Generator.
A plug that is spliced onto a different cord may be hazardous.
Only a qualified electrician should wire a plug onto a cord.
WARNING! Never exceed the rated capacity for this Generator,
as serious damage to the Generator and/or appliances, tools, and
equipment could result from an overload. Starting and running
wattage requirements should always be calculated when matching
this Generator’s wattage capacity to the appliance, tool, or
equipment.
Use the DC12 V Receptacle to power 12 VDC equipment.
WARNING! TO PREVENT SERIOUS INJURY: Do not charge batteries
without a proper charge controller. Do not overcharge.
a. Connect the items that require the most wattage first.
b. Connect “inductive” load appliances, tools, and equipment next. Inductive
loads are small hand tools and some small appliances.
c. Connect any lights next.
d. Voltage sensitive appliances, tools, and equipment should be the last to be connected to the Generator.
Plug voltage sensitive items such as TVs, DVD players, microwaves, and cordless telephones into a UL®
Listed voltage surge protector (not included). Then, connect the surge protector into the Generator.
IMPORTANT! Failure to connect and operate appliances, tools, and equipment in this sequence can cause
damage to the Generator, appliances, tools, and equipment and will void the Warranty of this Generator.

Evenly distributed
over outlets:
IF ANY CIRCUIT BREAKERS TRIP CHECK THE FOLLOWING:
1. Make sure that ALL circuit breakers are reset
before starting the Generator again.
2. Adjust the plugs so the loads are
shared across outlet circuits.
To achieve rated output from the Generator,
distribute loads over outlets.
The generator uses a 2-circuit system to supply power to the receptacles. The loads must
be evenly distributed across receptacles to prevent overload on a single circuit. If the loads
being drawn are below the max rated wattage of the generator, yet the overload light begins
blinking or the generator shuts off, try redistributing plugs across receptacles.
120V Only (3-wire) Adaptor Cord Connected to L14-30 Receptacle:
If the overload light begins blinking or the Generator shuts off, too much wattage is being drawn from one
circuit even though the rated wattage of the Generator has not been reached. If an additional plug is connected
to one of the duplex receptacles, move the plug to the other duplex receptacle. Restart the Generator.
Note: Only half the Generator’s rated wattage, or 3800W, will be delivered through
a 120V (3-wire) adaptor cord. Exceeding this may cause overload.
240V Cord Connected to L14-30 Receptacle:
The 240V cord will draw full wattage from both circuits. If further loads
are possible, distribute them across receptacles.

SAFETYOPERATIONMAINTENANCE SETUP
Before using the Generator, check that the products
you want to plug into the unit are below the rated and
maximum wattage ratings of the Generator. Use the
Wattage Calculation Table below, and the watts listed
on your products, to help calculate multiple
wattage totals.
To use the table:
1. Add up the Running Watts for all items you
would like to use at any given time.
2. Make sure that this total is under the 7,600
running wattage of the Generator.
3. Find the single highest starting watts for
the selected items and add to the total.
4. Make sure that this total is under the 9,500
max. starting wattage of the Generator.
5. Plug in and turn on products from largest wattage
to smallest.
