Important Safety Instructions
WARNING: Charge unit fully prior to use.
Keep unit clear of fire and water.
WARNING: Shock hazard.
Keep away from children. Do not insert foreign objects into the DC power
pack socket, the jump start cable port, or the ventilation hole, do not expose
this product to water, rain, snow, condensation, or spray. Do not open the
power pack expect to replace the internal battery. Have a qualified
technician perform any service work.
WARNING: Explosion hazard
Do not use this product where there are flammable fumes or gases, such as
in the bilge of a gasoline-powered boat, or near propane tanks. Do not use
this product in an enclosure containing automotive-type lead-acid batteries.
These batteries, unlike the sealed AGM battery in power pack, vent explosive
hydrogen gas which can be ignited by sparks from electrical connections.
When working on electrical equipment, always ensure someone is nearby to
help you in an emergency.
WARNING: Heated surface
Ensure at least 2” (5cm) air space is maintained on all sides of the power
pack. During operation, keep away from materials that may be affected by
high temperatures such as blankets, pillows and sleeping bags.
WARNING: Fire hazard
Never allow jump start cables’ red and black clamps to touch each other or
another common metal conductor. This could cause damage to the unit
and/or create a sparking/explosion hazard. Always disconnect the jump start
cables from the unit after use and clip the plastic guard over the jump start
cable port.
Jump start cable clamps must be connected positive to positive (red clip to
battery “+”) and negative to negative (black clip to battery “-“or engine
ground). A reverse polarity connection (positive to negative) may cause
damage to the unit and/or create a sparking/explosion hazard.
