Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep your work area clean and well lit. Cluttered benches and dark areas invite
accidents.
2. Do not operate power appliances in explosive atmospheres, such as in the
presence of flammable liquids, gases, or dust. Power appliances create sparks
which may ignite the dust or fumes.
3. Keep bystanders, children, and visitors away while operating a power appliance.
Distractions can cause you to lose control. Protect others in the work area from debris
such as chips and sparks. Provide barriers or shields as needed.
4. Grounded appliances must be plugged into an outlet properly installed and
grounded in accordance with all codes and ordinances. Never remove the
grounding prong or modify the plug in any way. Do not use any adapter plugs.
Check with a qualified electrician if you are in doubt whether the outlet is properly
grounded. If the appliance should electrically malfunction or break down, grounding
provides a low resistance path to carry electricity away from the user.
5. Double insulated appliances are equipped with a polarized plug (one blade is wider
than the other). This plug will fit in a polarized outlet only one wa y . If the plug does
not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified
electrician to install a polarized outlet. Do not change the plug in any wa y . Doub le
insulation eliminates the need for the three wire grounded power cord and grounded
power supply system.
6. Avoid body contact with grounded surfaces such as pipes, radiators, ranges, and
refrigerators. There is an increased risk of electric shock if your body is grounded.
SKU 92426 For technical questions, please call 1-800-444-3353 Page 2
7. Do not expose power appliances to rain or wet conditions. Water entering a power
appliance will increase the risk of electric shock.
8. Do not abuse the Power Cord. Never use the Power Cord to carry the appliance or
pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp
edges, or moving parts. Replace dama ged Power Cords immediately . Damaged P ower
Cords increase the risk of electric shock.
9. When operating a power appliance outside, use an outdoor extension cord marked
“W-A” or “W”. These extension cords are rated for outdoor use, and reduce the risk
of electric shock.
Personal Safety
10. Stay alert. Watch what you are doing, and use common sense when operating a
power appliance. Do not use a power appliance while tired or under the influence
of drugs, alcohol, or medication. A moment of inattention while operating power
appliances may result in serious personal injury.
11. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep
your hair , clothing, and gloves away fr om moving parts. Loose clothes, jewelry , or
long hair can be caught in moving parts.
12. Avoid accidental starting. Be sure the Power Switch is off before plugging in.
Carrying power appliances with your finger on the Power Switch, or plugging in power
appliances with the Power Switch on, invites accidents.
13. Do not overreach. Keep proper footing and balance at all times. Proper footing
and balance enables better control of the power appliance in unexpected situations.
14. Use safety equipment. Always wear eye protection when working with batteries.
Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for
appropriate conditions.
15. Do not allow 12 volt DC leads to come into contact with each other. 12 Volt short
circuits can cause severe burns and other injuries.

16. When using, only place the Charger on a flat, level, solid surface.
17. Do not force the Charger. Use the correct product for your application.
18. Do not use the Charger if the Power Switch does not turn it on or off. Any product
that cannot be controlled with the Power Switch is dangerous and must be replaced.
19. Disconnect the Power Cord Plug from the power source before making any
adjustments, changing accessories, or storing the appliance. Such preventive
safety measures reduce the risk of starting the appliance accidentally.
20. Store idle products out of reach of children and other untrained persons. The
Charger can be dangerous in the hands of untrained users.

Specific Safety Precautions for the Battery Charger
Caution: Only use the Battery Charger in a well ventilated area to prevent the accumulation
of acidic gasses.
1. Maintain labels and nameplates on the Battery Charger. These carry important
information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
2. Always wear safety impact eye goggles and heavy work gloves when working on or
around lead-acid batteries. Wear long sleeve shirt, long pants and work shoes. Using
personal safety devices reduce the risk for injury. Safety impact eye goggles and
heavy work gloves are available from Harbor Freight Tools.
3. Maintain a safe working environment. Keep the work area well lit. Make sure there is
adequate surrounding workspace. Always keep the work area free of obstructions,
grease, oil, trash, and other debris. Do not use a power tool in areas near flammable
chemicals, dusts, and vapors. Do not use this product in a damp or wet location.
4. Always unplug the Battery Charger from its electrical outlet before performing any
inspection, maintenance, or cleaning procedures.
5. Avoid contact with Battery Acid. If splashed, unplug Cnboard Battery Charger and
immediately wash effected area with clean water . Continue washing area until medical
help arrives.
6. Turn vehicle ignition off before making cable connections. Vehicle’s engine must be
cooled down before making cable connections.
7. Connect Battery Charger cables to proper polarities. Connect black cable to the
negative battery terminal, and the red cable to the positive battery terminal (For a
negative grounded system). Failure to do so could result in sparks, possible fire and
severe personal injury.
8. Keep cables clear of fan blades, belts, pulleys, and other moving parts of the engine
that may cause injury, or damage to the Battery Charger.
9. Use Battery Charger in well ventilated areas to prevent the accumulation of acidic
gasses.

15. Do not attempt to start a vehicle while recharging the unit’s internal battery.
16. Periodically check on the progress of the trickle charge. Do not leave this product
unattended for hours without periodically checking on it’s operation.
Note: The charger is designed to work automatically, cycling on and off by sensing the
battery voltage. It is mentioned above to not leave this product unattended for hours; this is
because in some circumstances the Battery Charger can overheat if it is attempting to
recharge a low battery, or one that is damaged or has sulfonated plates. The charger is to
be used on fully charged batteries in good condition. Its only purpose is to maintain the
level of charge at approximately 12 volts.
GROUNDING
WARNING! Improperly connecting the grounding wire can result in the risk of electric
shock. Check with a qualified electrician if you are in doubt as to whether the outlet is
properly grounded. Do not modify the power cord plug provided with the appliance. Never
remove the grounding prong from the plug. Do not use the appliance if the power cord or
plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will
not fit the outlet, have a proper outlet installed by a qualified electrician.
GROUNDED T OOLS: TOOLS WITH THREE PRONG PLUGS
1. Tools marked with “Grounding Required”
have a three wire cord and three prong
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 Figure A.)
2. The grounding prong in the plug is
connected through the green wire inside
the cord to the grounding system in the appliance. The green wire in the cord must be
the only wire connected to the appliance’s grounding system and must never be
attached to an electrically “live” terminal. (See Figure A.)

not require grounding. They have a special
double insulation system which satisfies
OSHA requirements and complies with the
Double Insulated
tools can use
3. The smaller the gauge number of the wire, the greater the capacity of the cord. For
example, a 14 gauge cord can carry a higher current than a 16 gauge cord.
(See Figure C.)
4. When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See Figure C.)
5. If you are using one extension cord for more than one appliance, add the nameplate
amperes and use the sum to determine the required minimum cord size.
(See Figure C.)
6. If you are using an extension cord outdoors, make sure it is marked with the suffix
“W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure your extension cord is properly wired and in good electrical condition.
