Safety Warnings and Precautions

WARNING: When using product, basic safety precautions should always be followed to

reduce the risk of personal injury and damage to equipment.

Read all instructions before using this product!

WORK AREA

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

2. Do not operate the Battery Charger in explosive atmospheres, such as in the

presence of ﬂammable liquids, gases, or dust. Electrical products create sparks which

may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away while operating the Battery Charger.

Distractions can cause you to lose control. Protect others in the work area from sparks.

Provide barriers or shields as needed.

ELECTRICAL SAFETY

4. Grounded products 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 as to whether the outlet is properly grounded. If a

grounded product should electrically malfunction or break down, grounding provides a low

resistance path to carry electricity away from the user.

SKU 93781 For technical questions please call 1-800-444-3353. Page 3

5. Double insulated products are equipped with a polarized plug (one blade is wider

than the other). This plug will ﬁt in a polarized outlet only one way. 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 way.

Double 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.

7. Do not abuse the Power Cord. Never use the Power Cord to carry the Battery Charger

or pull the Plug from an outlet. Keep the Power Cord away from heat, oil, sharp

edges, or moving parts. Replace damaged Power Cords immediately. Damaged Power

Cords increase the risk of electric shock.

8. When operating a power tool 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

9. Stay alert. Watch what you are doing, and use common sense when operating the

Battery Charger. Do not operate the Battery Charger while tired or under the

inﬂuence of drugs, alcohol, or medication.

10. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your

hair and clothing away from the Battery Charger. Loose clothes, jewelry, or long hair can

be caught in the Battery Charger, causing personal injury.

11. Use safety equipment. Always wear eye protection during assembly, use, and mainte-

nance.

entering electrically powered equipment will increase the risk of electric shock.

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 Battery Charger. Never remove the

grounding prong from the plug. Do not use the Battery Charger 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 TOOLS: 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 Battery Charger

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 tool. The green wire in the cord must be the only wire connected to

the Battery Charger’s grounding system and must never be attached to an electrically “live”

terminal. (See Figure A.)

3. A grounded appliance must be plugged into an appropriate outlet, properly installed and

grounded in accordance with all codes and ordinances. The plug and outlet should look like

those in the following illustration. (See Figure A.)

Figure A

DOUBLE INSULATED APPLIANCES: APPLIANCES WITH TWO PRONG PLUGS

Note: The Battery Charger has a Two Prong Plug.

1. Appliances marked “Double Insulated” do not require grounding. They have a special double

insulation system which satisﬁes OSHA requirements and complies with the applicable

standards of Underwriters Laboratories, Inc., the Canadian Standard Association, and the

National Electrical Code. (See Figure B.)

2. Double insulated tools may be used in either of the 120 volt outlets shown in the following

illustration. (See Figure B.)

Figure B

EXTENSION CORDS

1. Grounded appliances require a three wire extension cord. Double Insulated products can

use either a two or three wire extension cord.

2. As the distance from the supply outlet increases, you must use a heavier gauge 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 Figure C, next page.)

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 tool, 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. Always

replace a damaged extension cord or have it repaired by a qualiﬁed electrician before using

it.

8. Protect your extension cords from sharp objects, excessive heat, and damp or wet areas.

3. Keep plenty of fresh water and soap nearby in case battery acid contacts skin,

clothing, or eyes. Avoid touching eyes while working near a lead-acid battery. If battery

acid contacts skin or clothing, wash immediately with soap and water. If acid enters the

eyes, immediately ﬂood eyes with running cold water for at least 10 minutes and get medical

attention immediately.

4. NEVER smoke or allow a spark or ﬂame in the vicinity of a lead-acid battery or vehicle

engine.

5. Use caution to reduce the risk of dropping a metal tool onto a lead-acid battery. The

tool may spark or short circuit the battery or other electrical part that may cause an

explosion.

6. Remove personal metal items such as rings, bracelets, necklaces, and watches when

working with a lead-acid battery. A lead-acid battery can produce a short circuit current

high enough to weld a ring or other metal item, causing a severe burn.

7. Use the Battery Charger for charging lead-acid batteries only. This Battery Charger is

not intended to supply power to a low voltage electrical system other than in a starter motor

application. Do not use this Battery Charger for charging dry-cell batteries. Dry-cell

batteries may burst and cause serious personal injury and/or property damage. NEVER

charge a frozen battery.

Preparing To Charge:

1. If it is necessary to remove the battery from a vehicle to charge, always remove the

grounded terminal from the battery ﬁrst. Make sure all accessories in the vehicle are off,

so as not to cause an arc.

2. Make sure the area around the battery is well ventilated while the battery is being

charged.

3. Clean the battery terminals prior to charging the battery.

4. Add distilled water in each cell until the battery acid reaches the level speciﬁed by the

battery manufacturer. This helps purge excessive gas from the cells. Do not overﬁll. For

a battery without cell caps, carefully follow the battery manufacturer’s recharging instruc

tions.

5. Determine the voltage of the battery by referring to the vehicle owner’s manual, con-

ﬁrm it is 12 volt.

Charger Location:

1. Always locate the Battery Charger as far away from the battery as the Charger’s DC

cables permit.

2. Never place the Battery Charger directly above the battery being charged. Gases from

the battery will corrode and damage the Battery Charger.

3. Never allow battery acid to drip on the Battery Charger.

SKU 93781 For technical questions please call 1-800-444-3353. Page 8

4. Do not operate the Battery Charger in a closed-in area, or restrict ventilation in any

way.

5. Do not set a battery on top of the Battery Charger.

DC Connection Precautions:

1. Connect and disconnect DC output clamps only after removing the AC power cord

from the electrical outlet.

2. Never allow the DC output clamps to touch each other.

3. Attach the DC output clamps to the battery posts and twist or rock the clamps back

and forth several times to make a good connection. This helps keep the clamps from

slipping off the terminals, and helps to reduce the risk of sparking.

To Reduce Risk Of Sparking - When The Battery Is In The Vehicle:

1. Carefully position the AC input and DC output cords to reduce the risk of damage by

hood, door, or moving engine parts.

2. Stay clear of fan blades, belts, pulleys, and other moving parts that can cause

personal injury and/or property damage.

3. Check the polarity of the battery posts. A POSITIVE (+) battery post usually has a

larger diameter than a NEGATIVE (–) battery post.

4. To reduce explosion risk, never connect both Battery Charger DC output clamps

directly to the battery.
