Safety Warnings and Precautions
General Safety Warnings
Read all safety warnings and instructions.
Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Save all warnings and instructions for future reference.
WARNING! – RISK OF EXPLOSIVE GASES.
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.
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.
Work Area Safety
1. Keep work area clean and well lit.
Cluttered or dark areas invite accidents.
2. Do not operate Power Pack in explosive
atmospheres, such as in the presence of
flammable liquids, gases or dust. The Power Pack
can create sparks which may ignite the dust or fumes.
3. Keep children and bystanders away
while operating the Power Pack.
Distractions can cause you to lose control.
4. Store idle equipment. Always lock up tools
and keep out of reach of children.
Electrical Safety
1. Do not drop a metal tool onto battery. It
might spark or short-circuit battery or other
electrical part that may cause explosion.
2. 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.
3. Do not leave Power Pack unattended
while switched on. It could result
in fire and property damage.
4. Do not expose to rain or wet conditions.
Water entering the Power Pack will
increase the risk of electric shock.
5. Do not use an extension cord with this item.
6. Use of an attachment not recommended or
sold by the manufacturer may result in a risk
of fire, electric shock, or injury to persons.
7. To reduce risk of damage to electric plug
and cord, pull by plug rather than cord
when disconnecting the Adapter.
8. Do not operate with damaged cord or plug.
Replace the cord or plug immediately.
Personal Safety
1. 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.
2. 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.
3. NEVER smoke or allow a spark or flame
in vicinity of battery or engine. .
4. 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.
5. 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.
6. 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.

SAFETY OPERATION MAINTENANCEASSEMBLY
Service
Have your Power Pack serviced by a qualified repair person using only identical replacement parts.
This will ensure that the safety of the Power Pack is maintained.
Power Pack Safety Warnings

SAFETYOPERATIONMAINTENANCE SETUP
DC Appliance Compatibility
The Power Pack can run/charge 12VDC
auto, RV, marine, or other portable
appliances that draw 10 amps or less.
The lower the amount of watts the appliance draws,
the longer the Power Pack can
run/charge it before needing to be recharged.
Calculate the total wattage needed to run the
appliance before operation. You do not need
to calculate startup or surge wattages.
To calculate the size of the load you plan to use
with the Power Pack, use the following formula:
Amps x Volts = Watts
For example, if you use an appliance whose running
amps is 7 amps, you will need 84 watts of power (7 amps
x 12V = 84 Watts) to run the items. This figure is within
the capacity of the unit (10 amps x 12V = 120 Watts).
Note: Use this chart as a guideline only.
The actual power usage may vary based on the
model or brand of the appliance. Check the actual
wattage of your appliances and calculate the
amount of power needed to run/charge them.
