INSTRUCTIONS PERTAINING TO RISK OF FIRE,
ELECTRIC SHOCK, OR INJURY TO PERSONS
IMPORTANT SAFETY INSTRUCTIONS
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.
Damaged 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 electric 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
THE 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 the
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 protection. Avoid touching
eyes while working near battery.

Page 4 For technical questions, please call 1-888-866-5797. Item 56798
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 265°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. Use the Power Pack for jump-
starting a LEAD-ACID battery only.
b. For emergency use only.
Do not use the Power Pack as a
replacement for a vehicle battery.
c. Be sure area around battery
is well ventilated while battery
is being jump-started.
d. NEVER jump-start a frozen battery.
e. Do not attempt to jump-start a
vehicle with a non-rechargeable
or defective battery.
f. Study all battery manufacturer’s
specific precautions for
jump-starting.
g. DO NOT TOUCH POSITIVE
AND NEGATIVE BATTERY
CLAMPS TOGETHER.
h. Unplug the Power Pack from
its Adapter before connecting
its cables to a battery.
i. Connect and disconnect
battery cable clamps only
after setting any Power Pack
switches to OFF position.
j. Connect cables to proper
polarities. Connect red cable
to positive battery terminal and
black cable to vehicle chassis.
k. Locate Power Pack as far away
from battery as battery cables permit.
17. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
18. Store idle equipment. Always lock up
tools and keep out of reach of children.
19. Do not operate if Power Pack has
received a sharp blow, been dropped,
or otherwise damaged in any way;
take it to a qualified technician.
20. Do not leave Power Pack unattended
while switched on. It could result
in fire and property damage.
21. Do not expose to rain or wet conditions.
Water entering the Power Pack will
increase the risk of electric shock.

Page 5For technical questions, please call 1-888-866-5797.Item 56798
22. Do not use an extension
cord with this item.
23. 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.
24. Do not use Power Pack while you
are tired or under the influence
of drugs, alcohol or medication.
A moment of inattention while
operating Power Pack may result
in serious personal injury.
25. 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.
26. Maintain labels and nameplates.
These carry important safety
information. If unreadable or
missing, contact Harbor Freight
Tools for a replacement.
27. 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.
SAVE THESE INSTRUCTIONS.
