to touch together or contact the same 

piece of metal.

2.6 

Consider having someone nearby to 

come to your aid when you work near a  

lead-acid battery.

2.7 

Have plenty of fresh water, soap and 

baking soda nearby for use, in case battery 

acid contacts your eyes, skin, or clothing. 

2.8 

Wear complete eye and body protection, 

including safety goggles and protective 

clothing. Avoid touching your eyes while 

working near the battery.

2.9 

If battery acid contacts your skin or 

clothing, immediately wash the area 

with soap and water. If acid enters your 

eye, immediately flood the eye with cold 

running water for at least 10 minutes and 

get medical attention right away.

2.10 

If battery acid is accidentally swallowed, 

drink milk, the whites of eggs or water. 

DO NOT induce vomiting. Seek medical 

attention immediately.

2.11 

Neutralize any acid spills thoroughly with 

baking soda before attempting to clean up.

2.12 This product contains a lithium ion 

battery.

 In case of fire, you may use 

water, a foam extinguisher, Halon, CO

2

, 

ABC dry chemical, powdered graphite, 

copper powder or soda (sodium carbonate) 

to extinguish the fire. Once the fire is 

extinguished, douse the product with water, 

an aqueous-based extinguishing agent, 

or other nonalcoholic liquids to cool the 

product and prevent the battery from re-

igniting. NEVER attempt to pick up or move 

a hot, smoking, or burning product, as you 

may be injured. 

3.  PREPARING TO USE THE UNIT

WARNING! RISK OF CONTACT WITH 

BATTERY ACID. BATTERY ACID IS A 

HIGHLY CORROSIVE SULFURIC ACID.

3.1 

Make sure the area around the battery  

is well ventilated while the unit is in use.

3.2 

Clean the battery terminals before using the 

jump starter. During cleaning, 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.

3.3 

Determine the voltage of the battery by 

referring to the vehicle owner’s manual 

and make sure that the output voltage  

is 12V.

3.4 

Make sure that the unit’s cable clamps 

make tight connections.

4.  FOLLOW THESE STEPS WHEN CONNECTING TO A BATTERY

WARNING! A SPARK NEAR THE 

BATTERY MAY CAUSE A BATTERY 

EXPLOSION. TO REDUCE THE RISK 

OF A SPARK NEAR THE BATTERY:

4.1 

Attach the output cables to the battery and 

chassis as indicated below. Never allow 

the output clamps to touch each other.

4.2 

Position the DC cables to reduce the risk of 

damage by the hood, door and moving or 

hot engine parts. 

NOTE:

 If it is necessary 

to close the hood during the jump starting 

process, ensure that the hood does not 

touch the metal part of the battery clips or 

cut the insulation of the cables.

4.3 

Stay clear of fan blades, belts, pulleys 

and other parts that can cause injury.

4.4 

Check the polarity of the battery posts. 

The POSITIVE (POS, P, +) battery post 

usually has a larger diameter than the 

NEGATIVE (NEG, N, -) post.

4.5 

Determine which post of the battery is 

grounded (connected) to the chassis. 

If the negative post is grounded to the 

chassis (as in most vehicles), see step 

4.6. If the positive post is grounded to the 

chassis, see step 4.7.

4.6 

For a negative-grounded vehicle, connect 

the POSITIVE (RED) clamp from the 

Power Pack to the POSITIVE (POS, P, +) 

ungrounded post of the battery. Connect 

the NEGATIVE (BLACK) clamp to the 

vehicle chassis or engine block away from 

the battery. Do not connect the clamp to 

the carburetor, fuel lines or sheet-metal 

body parts. Connect to a heavy gauge 

metal part of the frame or engine block.

4.7 

For a positive-grounded vehicle, connect 

the NEGATIVE (BLACK) clamp from the 

Power Pack to the NEGATIVE (NEG, N, -) 

ungrounded post of the battery. Connect 

the POSITIVE (RED) clamp to the vehicle 

chassis or engine block away from the 

battery. Do not connect the clamp to the 

carburetor, fuel lines or sheet-metal body 

parts. Connect to a heavy gauge metal 

part of the frame or engine block.

4.8 

When disconnecting the unit, press the 

jump start button to turn off, remove 

the clamp from the vehicle chassis, 

then remove the clamp from the battery 

terminal.
