Replacing the fuse with a higher
rated fuse or another object is very
dangerous and can result in re, seri-
ous personal injury, or death.
Before every use, check for any10.
broken parts or mounting xtures,
and any other condition that may
affect proper operation. Any part
that appears damaged should be
carefully checked to determine that it
will operate properly and perform its
intended function.
Do not disassemble. Aside from11.
the fuse, this item has no replace-
able parts. If this product is dam-
aged and/or does not function prop-
erly with an unbroken fuse, the entire
unit must be replaced.
Use the right inverter for the job12. .
Do not attempt to force a small in-
verter or attachment to do the work
of a larger industrial inverter. There
are certain applications for which
this inverter was designed. It will do
the job better and more safely at the
rate for which it was intended. Do not
modify this inverter and do not use
this inverter for a purpose for which it
was not intended.
Do not overload this device.13. This
device is designed for loads up to
200 Watts at 120 Volts AC only.
Check the wattage of any device
before using this item to power it.
Some rechargeable appliances may
damage the Power Inverter or the ap-
pliance. When rst using a recharge-
able device, check its temperature
for the rst 10 minutes. If it becomes
abnormally hot, do not use this de-
vice with the Inverter.
This device is designed for use in14.
12 VDC, negative ground systems
only.
Allow adequate ventilation. Do not15.
cover this unit while it is plugged
in. This unit generates heat; without
proper ventilation it may overheat,
potentially causing a re hazard.
Leave this device unplugged16.

plates. These carry important safety
information. If unreadable or miss-
ing, contact Harbor Freight Tools for a
replacement.
Caution: This inverter must only be con-
nected to batteries with a nominal
output voltage of 12 volts. Lower
voltage will not operate the inverter
properly, and more voltage could
damage the inverter or the device
being powered. If more than one 12
volt battery is to be used, the batter-
ies must be connected in a parallel
circuit; batteries connected in a series
circuit will produce too much voltage.
Place the Power Inverter on a at sur-1.
face. Make sure it has adequate ven-
tilation and is not in direct sunlight.
Locate the Inverter close enough to
the vehicle battery so that the Cables
can easily reach between the Inverter
and the vehicle battery. Position the
Inverter so that the Outlets are easily
and safely accessible.
To connect the Cable Ring Terminals2.
to the (Positive) red and (Negative)
black Power Terminals on the back of
the Inverter:
Unthread the knobs covering thea.
Power Terminals.
Slide the red Cable’s Ring Termi-b.

Terminal and the black Cable’s Ring
Terminal over the post of the black

to the Positive (red) terminal on the
battery, then attach the black Cable’s
Alligator Clip to a clean unpainted
metal part of the chassis. (Note: If
connecting to a battery not installed
in a vehicle, connect to the Negative

will light up.
Note: If the green LED fails to light and the

ing Tips section near the end of this
manual to correct the issue before
continuing.

After use, turn all connected devices7.
or appliances off, unplug them, then
turn off the vehicle’s engine if it is
running. Keep the inverter turned on
and remove the alligator clips from
the battery posts, removing the Nega-
tive (black) clip rst, then the Positive
(red) clip. The Inverter green LED will
turn off, and the alarm and red LED
light will turn on as the Inverter pow-
ers down. Turn off the Inverter power
button.
Note: The total wattage of all items
plugged into the Power Inverter must
not use more than 200 watts during
continuous operation, otherwise the
Inverter may overload.
Note: If an alarm sound is heard, turn off
the appliances and check the Trou-
bleshooting Tips section near the end
of this manual to correct the issue
before continuing.
Caution: Some rechargeable appliances
may damage the Power Inverter
or the appliance. When rst using
a rechargeable device, check the
inverter’s temperature for the rst 10
minutes. If it becomes abnormally
hot, do not use this device with the
Inverter.
Caution: It is recommended that the ve-
hicle be running when you rst con-
nect the Power Inverter. Thereafter
the engine can be on or off. If you run
the Power Inverter with the engine
off it is recommended that you start
and run the engine every hour for at
least 10 minutes to recharge the bat-
tery. Doing this will help prevent any
unexpected shutdown of the equip-
ment. This will also help ensure that
there will be enough battery power
to start the vehicle. Due to the risk
of carbon monoxide inhalation, do
not run the vehicle’s engine within
an enclosed area.
You should not use your car battery
to power the Inverter for extended pe-
riods of time with appliances requir-
ing high continuous load levels. The
battery may become drained to the
point that it will not be able to start
your car.
Note: Deep cycle (marine and RV) bat-
teries can be charged more times
than a car battery, and are a better
choice for repeated use of the Power
Inverter.
Do not discharge your car battery
more than 10% of its total capacity,
and deep cycle batteries more than a
50% discharged state.

MAINTENANCE
TO PREVENT
SERIOUS INJURY
FROM ELECTRICAL SHOCK:
Do not open the inverter. Do
not touch any interior parts of
the Inverter.
Keep this unit clean and dry. Discon-1.
nect the unit before cleaning. Clean
only the outside of this unit with a
soft, dry cloth; never clean this unit
with water or harsh cleaners.
If the fuse needs replacing, take the2.
unit to a qualied technician.
Note: This device does not contain any
user replaceable parts. If it needs
service, take it to a qualied techni-
cian.

TROUBLESHOOTING TIPS
If the alarm sounds, this means that the input voltage is at or below 11 V. The bat-1.
tery needs recharging. You should stop using the Power Inverter and recharge the
battery. If this is not done, the Inverter will shut off automatically at 10.5V.
If you are unsure if the inverter will have the proper amount of current to run your2.
devices, add up the total of the continuous wattage for the items. If this gure is
under 200 then the Inverter will be able to run the items at the same time.
If your television will not start, it is important to keep in mind that some appliances3.
(including many televisions) may require two to six times their wattage to start up.
If your audio system buzzes while using this inverter, it is because some sound 4.
systems can not lter out the modied sine wave produced by the inverter. Use a
sound system that incorporates a higher quality power supply.
This inverter is made to minimize the interference with TV signals. However, 5.
especially with weak TV signals, some interference may still be visible. To correct
this, place the inverter as far away as possible from the television antenna and it’s
cables. Next, adjust the orientation of the inverter to the antenna cables and TV
power cord to minimize the interference. Also use a shielded antenna cable.
If the low battery alarm is on all the time, try these corrective measures: Recharge6.
battery if in poor condition. Next, check the battery connections. You may need to
clean the connectors.
If you are getting a low output voltage, try reducing the load to minimize watts. You 7.
may have overloaded the inverter. Reduce the number of watts you are powering.
Also, keep input voltage above 11 volts to maintain a constant ow of power.
If you are not getting any power output, turn the power switch Off and On again,8.
until the green power light comes on. Your devices may draw too much power to
operate them. The inverter may be in thermal shutdown. Let it cool down and
make sure there is adequate ventilation around the unit.
