Performance of your
jump starter
will depend upon several factors:
• A good, solid connection between the
jump starter
clamps and the battery
and ground connections are a must. Moving the clamps back and forth while
connecting to the battery will help create a better connection.
• Clean connections between your vehicle or equipment battery and its terminals
are very important. For an optimal connection, corrosion (soft grayish-white build-
up) on battery terminals must be removed. With the ignition turned off, disconnect
the battery cables and clean the terminals and battery posts with a baking soda
solution.
• All batteries are affected by temperature changes, and the small, lightweight
battery in the
jump starter
is more sensitive to storage temperature than a standard
automotive battery. The ideal storage environment is room temperature, or 68ºF.
Performance and Temperature
Note: Review this instruction manual and the instruction/safety manual provided by the
manufacturer of the vehicle being jump started.
Note: For optimum performance, do not store your jump starter below 50° when using as
a jump starter. NEVER charge or jump start a frozen battery.
1. Use in a well ventilated area. Shield eyes with safety glasses or goggles.
Jump Starting Instructions
• To prevent arcing, NEVER allow clamps to touch together or to contact the same
piece of metal.
• Use of an attachment not recommended or sold by the manufacturer may result in a
risk of damage to the unit or injury to personnel.
• When using the power extension cord, pull on the plug and never on the wire when
disconnecting.
• Do not recharge the jump starter with a damaged power extension cord. Replace it
immediately.
• The jump starter may be used under any weather condition – rain, snow, hot or cold
temperatures.
• Do not submerge in water.
• Do not operate with flammables such as gasoline, etc.
• If the jump starter receives a sharp blow or is otherwise damaged in any way, have
it checked by a qualified service person. If the jump starter is leaking battery acid, do
not ship it. Take it to the closest battery recycler in your area.
• Do not disassemble the jump starter. Have it checked by a qualified service person.
• The jump starter should never be left in a completely discharged state for any period
of time. Damage to the battery could be permanent, with poor performance as a
result. When not in use, recharge every three (3) months.
• Always store, use and charge the jump starter in an area where children cannot get
to the unit.
