Before using your portable power
pack, you should fully charge it.
The digital battery meter will show
when the unit is charging and when
it is fully charged. You can check
the actual battery voltage any time
by pressing the internal voltage
selector. Recharge every 30 days or
anytime the internal battery voltage
falls below 11.5V. Fluctuations in
temperature can accelerate battery
discharge. Check your unit often.
Charge using the supplied A/C char-
ger or use the Rescue 604095 in-cab
charging cord.
1. Turn on the power switch on the back of the Rescue 3100.
2. Check vehicle battery terminals before using the power pack; clean them if necessary.
3. Connect the red (po) clamp to the positive terminal or post on the discharged
battery.
4. Connect the black (negative –) clamp to a ground away from the battery, such as an
alternator bracket.
• Note: Some vehicles are equipped with positive and negative start terminals away
from the battery. Use these terminals when available.
5. Verify the green Smart Polarity light is on. If it is, press Start. If it is not, refer to the
troubleshooting section.
6. Verify the Power light is on. The unit is now supplying jump starting power to
your vehicle.
7. Start the engine. After approximately 6 seconds of continuous cranking, if the disabled
vehicle fails to start, stop and wait for 2 minutes. This prevents damage to your power
pack and to your vehicle’s system from overheating.
8. Turn off the power switch on the back of the power pack and disconnect the clamps,
first negative and then positive. Store clamps properly on unit.
9. Recharge power pack after use.
To use as a 12V Power Source
1. Connect the red (po) clamp to the positive input terminal and the black

2. Verify that the Low Voltage/Smart Polarity Off light is illuminated.
3. Press and hold the Start button for 4 seconds. The battery meter display will show a
countdown.
4. Verify the Power light is on. The power pack is now supplying current to your device.
5. Turn the unit off by turning the switch on the back of the power pack off, and then
disconnect the clamps.
6. Recharge power pack after use.
• If the Rescue 3100 is not fully charged it may shut down under heavy load if it cannot
deliver sufficient voltage.
• Failure to keep internal battery charged will lead to permanent battery damage.
