CAUTION: This generator is not intended to power sensitive electronic equip-7.
ment* without the addition of an appropriate line conditioner and surge pro-
tector (both not included). Sensitive electronic equipment should be operated
on approved inverter type generators or pure sine wave generators.
If the plugged in product operates abnormally or unusually slow, immediately stop
using the generator as a power source. Always read and adhere to the instruction
manual of the product to be powered, to make sure that it can be safely and efciently
powered by a portable generator.
Note: When using a generator to provide home standby electricity, a transfer switch
(sold separately) is needed to prevent back feeding power into the utility line.
Connections for standby power to a building electrical system must be made by a
qualied electrician. The connection must isolate the generator power from utility
power, and must comply with all applicable laws and electrical codes.
WARNING: Improper connections to a building electrical system can allow electrical
current from the generator to backfeed into the utility lines. Such backfeed may
electrocute utility company workers or others who contact the lines during a power
outage, and the generator may explode, burn, or cause res when utility power is
restored. Consult the utility company or a qualied electrician.
*Sensitive electronic equipment includes, but is not limited to, audio/video
equipment, some television sets, computers, and printers.
AC APPLICATIONS
Before connecting an appliance or power cord to the generator: Make sure that it1.
is in good working order. Faulty appliances or power cords can create a potential
for electrical shock.
If an appliance begins to operate abnormally, becomes sluggish or stops suddenly,2.
turn it off immediately. Disconnect the appliance, and determine whether the
problem is the appliance, or if the rated load capacity of the generator has been
exceeded.
Make sure that the electrical rating of the tool or appliance does not exceed that of3.
the generator. Never exceed the maximum power rating of the generator. Power
levels between rated and maximum may be used for no more than 30 minutes.
Substantial overloading will open the circuit breaker. Exceeding the time limit for4.
maximum power operation or slightly overloading the generator may not switch
the circuit breaker or circuit protector OFF, but will shorten the service life of the
generator.

(See Figure E.)
IMPORTANT:5. Allow the Generator to run at no load for ve minutes after each
start-up so that the Engine and Generator can stabilize.
To Connect Electrical Loads:
Start the Engine, and allow the Engine and Generator to run and warm up for ve 1.
minutes after starting with no electrical load.
2. WARNING! Connect 120 VAC appliances, tools, and equipment only to the
four 120 VAC Outlets (5). Connect 240 AC appliances, tools, and equipment only
to the one 240 VAC Outlet (6). Connect 12 VDC appliances, tools, and equipment
only to the 12 VDC Terminal (7). (See Figure C.)
3. CAUTION! Never exceed the rated capacity for this Generator, as serious dam-
age 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 equip-
ment.
Most appliances, tools, and equipment will list on the motor nameplate the starting4.
and running voltage and amperage requirements. Use the following formula to
convert voltage and amperage to wattage:
Volts x Amps = Watts (example: 120 volts x 3 amps = 360 watts)
To determine the approximate wattage requirement for most appliances, tools, and5.
equipment with “inductive” type motors, multiply the wattage that was calculated by
2 times to ensure adequate Generator capacity for motor load starting current.
NOTE:6. The starting and running wattage for “resistant” loads are the same. Ex-
ample: a 100 Watt light bulb requires only 100 Watts to start. Most resistant loads
will be listed in wattage.
Always power the largest electric motor rst. Then, plug in other appliances, tools, 7.
and equipment one at a time.
Connect “inductive” load appliances, tools, and equipment rst. Inductive loads a.
consist of small hand tools and some small appliances. Connect the items that
require the most wattage rst.
Connect any lights next.b.

INSPECTION, MAINTENANCE, AND CLEANING
1. WARNING! Always make sure the Engine’s Ignition (2) is in its “OFF” position
prior to performing any service, maintenance, or cleaning of the Generator or En-
gine. (See Figure C.)
Before each use,2. inspect the general condition of the Generator and Engine. Check
for loose screws, misalignment or binding of moving parts, cracked or broken parts,
loose hose connections, and any other condition that may affect the safe opera-
tion of the Generator and Engine. If abnormal noise or vibration occurs, have the
problem corrected before further use.
Do not use damaged equipment.
Generator maintenance:3.
Keep the Generator clean and dry at all times.a.
The Generator should not be operated or stored in locations that include exces-b.
sive moisture, dust, ammable or corrosive vapors. If these substances are on
the Generator, clean with a cloth or soft brush.
Do not use a garden hose or anything with liquid to clean the Generator. Liquidc.
may enter the cooling air slots and could damage the interior workings of the
Generator.
Voltage sensitive appliances, tools, and equipment should be the last to be con-c.
nected to the Generator and the rst to be disconnected. Plug voltage sensitive
items such as T.V.’s, VCR’s, microwaves, and cordless telephones into a UL
listed voltage surge protector (not included). Then, connect the UL Listed surge
protector into the Generator.
8. CAUTION! Failure to connect and operate appliances, tools, and equipment in
this sequence can cause damage to the Generator, appliances, tools, and equip-
ment and will void the warranty on this Generator.
Once the Engine is running, simply connect the 120 volt appliances, tools, and9.
equipment into the 120 VAC Outlets (5). Connect a 240 volt appliance, tool, or
equipment into the 240 VAC Outlet (6). Or connect a 12 volt appliance, tool, or
equipment into the 12 VDC Outlet (8). (See Figure C.)
IMPORTANT:10. If Engine speed or voltage uctuates with a load below 250 Watts,
move the Engine Choke Lever (21A) to the “HALF-CHOKE” position.
(See Figure E.)
When nished using the Generator, disconnect all electrical loads. Turn the Engine 11.
Ignition (2) to its “OFF” position to stop the Engine. Then, close the Engine Fuel
Valve (41). (See Figures C and E.)

Engine maintenance:4.
After rst 5 to 8 hours of use: a. Change oil. Then, change oil every 50 hours
of use. Change oil every 25 hours of use when operating the Engine under a
heavy load or in high temperatures. To change the oil, remove the Plug (59A)
and allow the old oil to drain in a proper container. Once drained, replace the
Plug. If the Engine will be run in temperatures above 32° Fahrenheit, use SAE
10W-30 weight oil. If the Engine will be run in temperatures below 32° Fahr-
enheit, use SAE 5W-30 weight oil. To ll the Engine crankcase with new oil,
unscrew and remove the Oil Dipstick (65A). Pour engine oil into the oil ll hole
until the level of oil is even with the bottom edge of the oil ll hole (if you cannot
see the oil through the oil ll hole, then the oil is too low and more oil must be
added). Make sure to screw the Oil Dipstick (65A) rmly back into its Dipstick
Hole. Also, make sure to dispose of the old oil according to local waste disposal
requirements.(See Figure F.)

and squeeze thoroughly to dry. Then, squirt several drops of a light weight oil
onto the Element. Use compressed air to clean the Air Filter Separator. Then
replace the Air Filter Separator, Air Filter Element, and Air Filter Cover. Clean
more often under dusty conditions or when airborne debris is present. Replace
Air Filter parts if necessary. (See Figure G.)
After every 100 hours of use:c. Replace the Spark Plug (28A). To do so, remove
the Spark Plug Wire (36A). Use the accessory Spark Plug Wrench Kit (86A) to
remove the old Spark Plug. Install a new Spark Plug. Then, replace the Spark
Plug Wire. (See Figure G.)
