WARNING - When using this product, basic precautions should always be followed, including the following:
1. Read all the instructions before using the product.
2. To reduce the risk of injury, close supervision is
necessary when the product is used near children.
3. Do not put fingers or hands into the product.
4. Use of an attachment not recommended or sold
by power pack manufacturer may result in a risk
of fire, electric shock, or injury to persons.
5. To reduce risk of damage to the electric plug
and cord, pull the plug rather than the cord
when disconnecting the power pack.
6. Do not use a battery pack or appliance that is
damaged or modified. Damage or modified
batteries may exhibit unpredictable behavior
resulting in fire, explosion or risk of injury.
7. Do not operate the power pack with a damaged
cord or plug, or a damaged output cable.
8. Do not disassemble the power pack, take it
to a qualified service person when service or
repair is required. Incorrect reassembly may
result in a risk of fire or electrical shock.
9. To reduce the risk of electric shock, unplug
the power pack from the outlet before
attempting any instructed servicing.
10. WARNING - RISK OF EXPLOSIVE GASES.
a. WORKING IN VICINITY OF A LEAD-ACID
BATTERY IS DANGEROUS. 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 POWER PACK.
b. To reduce risk of battery explosion, follow
these instructions and those published by
battery manufacturer and manufacturer of
any equipment you intend to use in vicinity
of battery. Review cautionary marking
on these products and on engine.
11. PERSONAL PRECAUTIONS
a. Consider having someone close
enough by to come to your aid when
you work near a lead-acid battery.
b. Have plenty of fresh water and soap nearby in
case battery acid contacts skin, clothing, or eyes.
c. Wear complete eye protection and clothing.
Avoid touching eyes while working near battery.
d. If battery acid contacts skin or clothing,
wash immediately with soap and water. If
acid enters eye, immediately flood eye with
running cold water for at least 10 minutes
and get medical attention immediately.
e. NEVER smoke or allow a spark or flame
in vicinity of battery or engine.
f. Be extra cautious to reduce risk of dropping
a metal tool onto battery. It might spark
or short-circuit battery or other electrical
part that may cause explosion.
g. 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 the
like to metal, causing a severe burn.
12. When charging the internal battery,
work in a well ventilated area and do
not restrict ventilation in any way.
13. Under abusive conditions, liquid may be
ejected from the battery; avoid contact.
If contact accidentally occurs, flush with
water. If liquid contacts eyes, additionally
seek medical help. Liquid ejected from the
battery may cause irritation or burns.
14. Do not expose a power pack to fire or excessive
temperature. Exposure to fire or temperature
above 104° F may cause explosion.
15. Have servicing performed by a qualified
repair person using only identical
replacement parts. This will ensure that
the safety of the product is maintained.

16. Attach output cables to a battery and
chassis as indicated below. Never allow
the output clamps to touch one another.
a. The Jump Starter must be fully charged.
Recharge as needed, according to Charging
the Jump Starter section on page 7.
b. Turn off the vehicle ignition switch and all
accessories (lights, radio, climate control, etc.).
c. Insert Jumper Cable into ‘Engine Start’ port
on Jump Starter. If properly connected to the
Jump Starter, the Clamp’s LED light will start
flashing green, indicating ‘Standby’ mode.
d. Connect the red Positive Battery Cable to
vehicle’s positive battery terminal. Connect the
black Negative Battery Cable to the vehicle
chassis. The Clamp’s green LED light will turn
to solid green, indicating ‘Ready’ mode.
e. Attempt to start vehicle. If Vehicle does not
start right away, wait 20-30 seconds while
the clamps are connected to the battery
and the Jump Starter is on to allow boosting
the discharged battery, and try again.
f. After the vehicle is started, first remove
Cable from the Jump Starter, then remove
the black Negative Battery Cable, and
lastly the red Positive Battery Cable.
g. Recharge the Jump Starter if battery level
is below 50%, or every 3-6 months.
17. Keep work area clean and well lit. Cluttered
or dark areas invite accidents.
18. Keep children and bystanders away
while operating the Jump Starter.
Distractions can cause you to lose control.
19. Store idle equipment. Always lock up tools
and keep out of reach of children.
20. Do not leave Jump Starter unattended
while switched on. It could result
in fire and property damage.
21. Do not expose to rain or wet conditions.
Water entering the Jump Starter
will increase the risk of fire.
22. Wear ANSI-approved splash-
resistant safety goggles and heavy-
duty rubber work gloves
whenever connecting,
disconnecting, or working near battery.
Battery acid can cause permanent blindness.
Avoid touching eyes while working near battery.
23. Do not use Jump Starter while you are tired or
under the influence of drugs, alcohol or medication.
A moment of inattention while operating Jump
Starter may result in serious personal injury.
24. People with pacemakers should consult their
physician(s) before use. Electromagnetic fields in
close proximity to heart pacemaker could cause
pacemaker interference or pacemaker failure.
25. Maintain labels and nameplates on the Jump Starter.
These carry important safety information.
If unreadable or missing, contact
Harbor Freight Tools for a replacement.
26. The warnings, precautions, and instructions
discussed in this instruction manual cannot
cover all possible conditions and situations
that may occur. It must be understood by the
operator that common sense and caution are
factors which cannot be built into this product,
but must be supplied by the operator.
