IMPORTANT SAFETY INSTRUCTIONS - SAVE THESE INSTRUCTIONS -1.
This manual contains important safety and operating instructions
RISK OF ELECTRIC SHOCK OR FIRE.
Read the entire manual before using this product. Failure to do so could result1.1
in serious injury or death.
Keep out of reach of children.1.2
Use only recommended attachments. Use of an attachment not recommended1.3
or sold by the jump starter manufacturer may result in a risk of re, electric
shock or injury to persons or damage to property.
Do not put ngers or hands into any of the 1.4 jump starter’s outlets.
Do not expose the1.5 jump starter to rain or snow.
Use of an improper extension cord to charge the jump starter could result in a1.6
risk of re and electric shock. Make sure:
That the pins on the plug of the extension cord are the same number, size•
and shape as those of the plug on the jump starter.
That the extension cord is properly wired and in good electrical condition.•
That the extension cord has a wire size of 18 gauge (AWG) or larger and is•
50 feet long or less.
To reduce the risk of electric shock, turn off and/or unplug the jump starter1.7
before attempting any maintenance or cleaning. Simply turning off the controls
will not reduce this risk.
Do not operate the1.8 jump starter if it has received a sharp blow, been dropped
or otherwise damaged in any way; take it to a qualied service person. (Call
customer service at: 1-800-732-7764.)

service or repair is required. Incorrect reassembly may result in a risk of re or
electric shock. (Call customer service at: 1-800-732-7764.)
RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGEROUS.1.10
BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY
OPERATION. FOR THIS REASON, IT IS OF UTMOST IMPORTANCE THAT
YOU FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE
JUMP STARTER.
To reduce the risk of a battery explosion, follow these instructions and those1.11
published by the battery manufacturer and the manufacturer of any equipment
you intend to use in the vicinity of the battery. Review the cautionary markings
on these products and on the engine.

•3 •
PERSONAL PRECAUTIONS2.
RISK OF EXPLOSIVE GASES. A
SPARK NEAR THE BATTERY MAY
CAUSE A BATTERY EXPLOSION.
TO REDUCE THE RISK OF A
SPARK NEAR THE BATTERY:
Working in the vicinity of a lead-acid battery is dangerous. Batteries generate2.1
explosive gases during normal battery operation. For this reason, it is of
utmost importance that you follow the instructions each time you use the
jump starter.
NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.2.2
Do not permit the internal battery of the jump starter to freeze. Never charge a2.3
frozen battery.
To prevent sparking, NEVER allow clips to touch together or contact the same2.4
piece of metal.
When charging the internal battery of the jump starter, work in a well ventilated2.5
area and do not restrict the ventilation in any way.
Be extra cautious to reduce the risk of dropping a metal tool onto a battery. It2.6
might spark or short-circuit the battery or other electrical part that may cause
an explosion.
Remove personal metal items such as rings, bracelets, necklaces and watches2.7
when working with a lead-acid battery. A lead-acid battery can produce a short-
circuit current high enough to weld a ring or the like to metal, causing a
severe burn.
Be sure the area around the battery is well ventilated while the jump starter is2.8
being used.
RISK OF CONTACT WITH BATTERY ACID.
BATTERY ACID IS A HIGHLY CORROSIVE
SULFURIC ACID.
Consider having someone close enough by to come to your aid when you work2.9
near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts your2.10
skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and2.11
protective clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, immediately wash the area with2.12
soap and water. If acid enters your eye, immediately ood the eye with cold
running water for at least 10 minutes and get medical attention right away.
If battery acid is accidentally swallowed, drink milk, the whites of eggs or water.2.13
DO NOT induce vomiting. Seek medical attention immediately.
Stay clear of fan blades, belts, pulleys and other parts that may cause injury.2.14
Clean the battery terminals before using the jump starter. During cleaning,2.15
keep airborne corrosion from coming into contact with your eyes, nose and
mouth. Use baking soda and water to neutralize the battery acid and help
eliminate airborne corrosion. Do not touch your eyes, nose or mouth.
Determine the voltage of the battery by referring to the vehicle owner’s manual2.16
and make sure that the output voltage of the jump starter is correct.
Make sure that the jump starter cable clips make tight connections.2.17

FOLLOW THESE STEPS WHEN CONNECTING TO A BATTERY3.
A SPARK NEAR THE BATTERY
MAY CAUSE A BATTERY
EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR THE
BATTERY:
NEGATIVE GROUNDED SYSTEM
Attach the output cables to the battery and chassis as indicated below. Never3.1
allow the output clips to touch each other.
Position the DC cables to reduce the risk of damage by the hood, door and3.2
moving or hot engine parts. NOTE: If it is necessary to close the hood during
the charging process, ensure that the hood does not touch the metal part of
the battery clips or cut the insulation of the cables.
Stay clear of fan blades, belts, pulleys and other parts that can cause injury.3.3
Check the polarity of the battery posts. The POSITIVE (POS, P, +) battery post3.4
usually has a larger diameter then the NEGATIVE (NEG, N, -) post.
Determine which post of the battery is grounded (connected) to the chassis.3.5
If the negative post is grounded to the chassis (as in most vehicles), see step
3.6. If the positive post is grounded to the chassis, see step 3.7.
For a negative-grounded vehicle, connect the POSITIVE (RED) clip from the3.6
jump starter to the POSITIVE (POS, P, +) ungrounded post of the battery.
Connect the NEGATIVE (BLACK) clip to the vehicle chassis or engine block
away from the battery. Do not connect the clip to the carburetor, fuel lines or
sheet-metal body parts. Connect to a heavy gauge metal part of the frame or
engine block.
For a positive-grounded vehicle, connect the NEGATIVE (BLACK) clip from3.7
the jump starter to the NEGATIVE (NEG, N, -) ungrounded post of the battery.
Connect the POSITIVE (RED) clip to the vehicle chassis or engine block away
from the battery. Do not connect the clip to the carburetor, fuel lines or sheet-
metal body parts. Connect to a heavy gauge metal part of the frame or
engine block.
When disconnecting the jump starter, turn all switches to off (if applicable),3.8
remove the clip from the vehicle chassis and then remove the clip from the
battery terminal.
