included. If any parts are missing or broken, please call Harbor Freight Tools at the number
shown on the cover of this manual as soon as possible.
NOTE: For additional references to the parts listed in the following pages, refer to the
Assembly Diagram on page 19.
To Install A Battery:
1.NOTE: The Generator requires the installation of a 12 volt battery (not included).
The battery must be no larger than 5” wide x 7-3/4” long x 8-1/2” high.
2. WARNING! Battery fluid leakage may occur under extreme usage or temperature
conditions. If battery fluid comes in contact with skin, wash with soap and water and
rinse with lemon juice and vinegar. If the fluid comes into contact with the eyes,
flush with water for several minutes and contact a doctor immediately. Never burn a
battery, as it can explode in a fire. Do not use the Generator with a leaking battery.
Contact local solid waste authorities for instructions on correct disposal or recycling
of a battery.
3.Carefully place a fully charged, 12 volt battery in the Battery Holder located at the
base of the Generator.
4.The Engine has
two
power cables that must be connected to the battery. Connect
the cable with the RED (+ POSITIVE) terminal to the (+ POSITIVE) terminal on the
battery. Connect the cable with the BLACK (- NEGATIVE) terminal to the(- NEGATIVE) terminal on the battery. (See Figure C.)
5.Insert the bottom, “L” shaped portion of one Battery Support Stud (39) in each end of
the Battery Holder. Then, insert the Battery Holding Plate (40) onto the two Battery
Support Studs and allow the Battery Holding Plate to rest on top of the battery. Secure
the battery in place by tightening the two Nuts (49) onto the two Battery Support
Studs. Do not overtighten, as it may damage the battery. (See Figure C.)
1.NOTE: During operation, it may be necessary to refer to the
Operation, Maintenance, and Parts manual
(included) for detailed information about
Engine manufacturer’s
starting, running, and stopping the Engine.
2.Check to make sure the Engine’s “ON/OFF” Switch is in its “OFF” position.
3.Unscrew and remove the Engine’s Oil Fill Cap located at the bottom of the Engine
Crankcase. Check to make sure the oil level is even with the top of the Oil Fill Hole.
If necessary, add oil until its level is even with the Oil Fill Hole. Then, screw the Oil
Fill Cap back into the Oil Fill Hole.
NOTE: Check with the Engine manufacturer’s
manual for the proper type of engine oil required for use.
(See Figure D.)
4.Check the Fuel Gauge (34) for the amount of unleaded gasoline in the Fuel Tank
(32). If necessary, remove the Fuel Tank Cap (37) and refill the Fuel Tank with unleaded gasoline. Then, replace the Fuel Tank Cap.
1.Turn the Fuel Valve (31) to its vertical
“OPEN” position.
(See Figure F.)
2.Move the Engine’s Choke all the way
to the left to its “START” position.
(See Figure F.)
3.Turn the Engine’s “ON/OFF” switch to
its “
ON” position. (See Figure G.)
4.Insert the Ignition Key into the Ignition Switch (45), and turn the Ignition
Key to the right to start the Engine.
(See Figure H.)
5.Allow the Engine to run for several
seconds, then move the Engine’s
Choke all the way to the left to its
“RUN” position. (See Figure F.)

1.Prior to powering tools and equipment, make sure the Generator’s rated voltage,
wattage, and amperage capacity (120V/ 15 AMP and 240V/ 15 AMP) is adequate
to supply all electrical loads that the unit will power. If powering exceeds the
Generator’s capacity, it may be necessary to group one or more of the tools and/or
equipment for connection to a separate Generator.
2.Once the Generator is running, simply connect the Power Cords of 120 volt powered
tools and equipment into the 120 volt Outlets (43). If a 240 volt tool or equipment is
used, connect its power cord into the 240 volt Twistlock Outlet (44). (See Figure I.)
3.NOTE: The Generator features
the AC circuit in case of an overload. Should an overload occur one or both of the
Breakers will “trip”, interrupting the circuit (disconnecting power to the connected
tools and/or equipment). In this case, refer to Step #1 in this section. Then, reset
the circuitry system by depressing the Breaker(s). Restart the Generator and
continue powering the remaining tools and equipment. (See Figure I.)

4.When finished using the Generator, turn the ON/OFF switch on the engine’s fan
shroud to its “OFF” position, and remove the Ignition Key from the Ignition Switch
(45). (See Figure H.)
5.After the Engine and Generator have completely cooled, store the Generator in a
safe, clean, dry location (if not already installed in one).
1.NOTE: Preventative maintenance procedures and frequency will vary depending
on the amount of Generator use. Refer to the
Maintenance, and Parts manual
(included) for detailed information regarding
maintenance of the Engine.
2.CAUTION! Always turn off the Engine and remove the Ignition Key. Allow
sufficient time for the Engine and Generator to completely cool. Then,
disconnect the negative battery cable from the battery before performing any
inspection, maintenance, or cleaning.
3.BEFORE EACH USE, inspect the general condition of the Generator. Check for
loose screws, misalignment or binding of moving parts, cracked or broken parts,
damaged electrical wiring, and any other condition that may affect its safe operation.
If abnormal noise or vibration occurs, have the problem corrected before fur ther
use.
Do not use damaged equipment.
4.BEFORE EACH USE, check to make sure the Engine’s oil level is adequate. Refer
to the Engine manufacturer’s Operation, Maintenance, and Parts Manual (included)
for specific information.

5.DAILY: With a soft brush, cloth, or vacuum, remove all debris from the Generator.
Then, use a premium quality, lightweight machine oil to lubricate all moving parts.
