Important Safety Instructions
WARNING: Fire hazard
Jump-start cable clamps must be connected positive to
positive (red clamp to battery "+") and negative to negative
(black clamp to battery "-"). A reverse polarity connection
(positive to negative) may cause damage to the unit and/or
create a sparking/explosion hazard.
WARNING: Fire hazard
The jump-start feature is designed for short term operation
only—less than 4 seconds. Operating the jump-start feature
for more than 4 seconds may cause damage to the unit. Allow
the XPower Powerpack 400 and XPower Powerpack 400 Plus
to cool down for at least 3 minutes after each jump-start.
WARNING: Risk of explosion, fire or burns
The battery terminals exposed at the Jump-Start Cable Port
have enough energy present to cause a spark, creating an
explosion hazard, or to cause burns if a metal object contacts
both terminals. Always clip the plastic guard over the Port
when not in use.
WARNING: Fire Hazard - XPower Powerpack
400 Plus
Do not leave the compressor unattended while operating. The
compressor is designed for short term operation only.
Operation of the compressor over an extended period of time
will cause the compressor unit to overheat and may cause
damage. Allow the compressor to cool down for 10 minutes
after each 10 minutes of continuous operation.
