Grounded Tools: Tools with Three Prong Plugs
Tools marked with “Grounding Required” have a three wire cord and three prong
1.
grounding plug. The plug must be connected to a properly grounded outlet. If
the tool should electrically malfunction or break down, grounding provides a
low resistance path to carry electricity away from the user, reducing the risk of
electric shock. (See 3-Prong Plug and Outlet.)
The grounding prong in the plug is connected through the green wire inside the
2.
cord to the grounding system in the tool. The green wire in the cord must be the
only wire connected to the tool’s grounding system and must never be attached
to an electrically “live” terminal. (See 3-Prong Plug and Outlet.)
The tool must be plugged into an appropriate outlet, properly installed and
3.
grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the following illustration.
(See 3-Prong Plug and Outlet.)
3-Prong Plug and Outlet
Outlets for 2-Prong Plug
Double Insulated Tools: Tools with Two Prong Plugs
Tools marked “Double Insulated” do not require grounding. They have a special
1.
double insulation system which satises OSHA requirements and complies
with the applicable standards of Underwriters Laboratories, Inc., the Canadian
Standard Association, and the National Electrical Code.
(See Outlets for 2-Prong Plug.)
Double insulated tools may be used in either of the 120 volt outlets shown in the
2.
preceding illustration. (See Outlets for 2-Prong Plug.)
Extension Cords
Grounded tools require a three wire extension cord. Double Insulated tools
1.
can use either a two or three wire extension cord.
As the distance from the supply outlet increases, you must use a heavier gauge
2.
extension cord. Using extension cords with inadequately sized wire causes a
serious drop in voltage, resulting in loss of power and possible tool damage.
(See Table A.)
Page 6SKU 97047 For technical questions, please call 1-800-444-3353.
Page 7
The smaller the gauge number of the wire, the greater the capacity of the cord.
3.
For example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Table A.)
When using more than one extension cord to make up the total length, make
4.
sure each cord contains at least the minimum wire size required. (See Table A.)
If you are using one extension cord for more than one tool, add the nameplate
5.
amperes and use the sum to determine the required minimum cord size.
(See Table A.)
If you are using an extension cord outdoors, make sure it is marked with the
6.
sufx “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
Make sure the extension cord is properly wired and in good electrical condition.
7.
Always replace a damaged extension cord or have it repaired by a qualied
electrician before using it.
Protect the extension cords from sharp objects, excessive heat, and damp or
8.
wet areas.

SET UP INSTRUCTIONS
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the
beginning of this manual including all text under subheadings therein
before set up or use of this product.
WARNINGWARNING
Risk of Fire. The positive battery terminal connection must
be the LAST connection made and must be done with the
Inverter’s power switch Off.
CAUTIONCAUTION
This Inverter must only be connected 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 batteries must
be connected in a parallel circuit; batteries connected in a
series circuit will produce too much voltage.
For the power inverter to work properly, your power source must provide 12 volts
DC, and the power source must provide enough current (i.e., 46 amps to oper-
ate the load of 560 Watts or under).

Page 10SKU 97047 For technical questions, please call 1-800-444-3353.
Page 11
Cleaning, maintenance, and lubrication
BEFORE EACH USE, inspect the general condition of the tool. Check for loose
1.
screws, misalignment or binding of moving parts, cracked or broken parts and
any other condition that may affect its safe operation.
AFTER USE, clean external surfaces of the tool with clean, moist cloth.
2.
Due to the sensitive wiring and electrical circuits within this device, and the
3.
possibility of injury, the fuses inside this unit are to be replaced only by a
qualied technician. Also, this unit must have all energy storing electronics
discharged before opening; test for voltage to verify that the unit is safe before
opening.
Troubleshooting
1. If the low battery alarm sounds, this means that the input voltage is below the
necessary 10.5 V. The battery needs recharging. You should stop using the
appliance and then recharge the battery. If this is not done, the Inverter will shut
off automatically at around 10 V.
2. If you are unsure if the inverter will have the proper amount of current to run the
device, use this rough guideline: Take the power consumption of the load in watts
and divide it by 12 (input voltage). The result will be the approximate number of
amps needed to power your device.
Example: Load is rated at 312 watts. 312 watts / 12 V = 26 amps needed. You
could use this device with the inverter.
3. If your television will not start, it is important to keep in mind that some appliances
(including many televisions) may require two to six times their wattage to start up.
4. If your audio system buzzes while using this inverter, it is because some sound
systems can not lter out the modied sine wave produced by the inverter. Use a
sound system that incorporates a higher quality power supply.
5. This inverter is made to minimize the interference with TV signals. However,
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.
6. If the low battery alarm is on all the time, try these corrective measures: Recharge
battery if in poor condition. Next, check the battery connection. You may need to
clean the connectors.
7. If you are getting a low output voltage, try reducing the load to minimize watts. You
may have overloaded the inverter. Reduce your load to 950 watts. Also, keep input
voltage above 10.5 volts to maintain a constant ow of power.
8. If you are not getting any power output, turn the power switch Off and On again,
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.
