2. PERSONAL PRECAUTIONS
WARNING! RISK OF EXPLOSIVE GASES. A SPARK NEAR THE
BATTERY MAY CAUSE A BATTERY EXPLOSION. TO REDUCE THE
RISK OF A SPARK NEAR THE BATTERY:
2.1 NEVER smoke or allow a spark or ame in the vicinity of a battery or engine.
2.2 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 to
metal, causing a severe burn.
2.3 Be extra cautious, to reduce the risk of dropping a metal tool onto the
battery. It might spark or short-circuit the battery or other electrical
part that may cause an explosion.
2.4 Do not permit the internal battery of the unit to freeze. Never charge a
frozen battery.
2.5 To prevent sparking, NEVER allow clamps 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
ood 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 re, you
may use water, a foam extinguisher, Halon, CO2, ABC dry chemical,
powdered graphite, copper powder or soda (sodium carbonate)
to extinguish the re. Once the re 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 Plug the clamps into the unit, and then 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 jump starter 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 jump starter 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 nished using the jump starter, remove the clamp from the
vehicle chassis and then remove the clamp from the battery terminal.
Disconnect the clamps from the unit.
