Jump Starter Operation

1. Before Connecting to Battery

? NOTE: Some late model vehicles have on-board computers that might be damaged if jump-started. Always read the vehicle owner's manual before attempting to jump-start (battery boost) the vehicle to determine if external-starting assistance is acceptable.

⚠️ CAUTION: Place device on a flat and stable surface near the vehicle battery, clear of moving parts. Do not smoke, use matches, lighters, or open flame. Do not touch battery clamps together to prevent short circuit or arching.

  1. Turn off the vehicle ignition and all accessories.
  2. Set the emergency brake and put the vehicle in park (automatic transmission).
  3. Ensure the device booster switch is in the Off position.
  4. Access the device booster clamps by squeezing the handles. Pull clamps outward and remove from storage holders.
  5. Determine the polarity of the vehicle battery terminals. The positive (+) terminal is usually larger than the negative (-). Follow instructions for negative or positive grounded systems below.

2. Negative Ground System Connection

(Negative battery terminal is grounded to chassis. Most vehicles use this system. Refer to vehicle owner's manual if unsure.)

  1. Securely connect the positive (+) red clamp to the positive (POS, P, +) terminal of the vehicle battery or remote positive terminal.
  2. Securely connect the negative (-) black clamp to the vehicle chassis, engine block, or a non-moving grounded metal part, as far away from the battery as possible. Do not clamp directly to carburetor, fuel lines, or non-grounded sheet-metal body parts.

? Device green LED is On/Lit (proper battery polarity connection).

? NOTE: If red LED is On/Lit and alarm sounds, stop! Carefully disconnect and reconnect clamps to the proper battery polarity.

3. Positive Ground System Connection

(Positive battery terminal is grounded to chassis or other metallic part of the vehicle. Refer to vehicle owner's manual if unsure.)

  1. Securely connect the negative (-) black clamp to the negative (NEG, N, -) ungrounded terminal of the vehicle battery.
  2. Securely connect the positive (+) red clamp to the vehicle chassis, engine block, or a non-moving grounded metal part, as far away from the battery as possible. Do not clamp directly to carburetor, fuel lines, or sheet-metal body parts.

? Device green LED is On/Lit (proper battery polarity connection).

? NOTE: If red LED is On/Lit and alarm sounds, stop! Carefully disconnect and reconnect clamps to the proper battery polarity.

4. Jump Starting Battery

  1. Turn the device booster switch clockwise to the On position.
  2. Allow 2 or 3 minutes charging time. It is recommended to have a second person assist holding the device unit securely.
  3. Turn the ignition key and attempt to start the vehicle.
  4. ? NOTE: If the vehicle does not start after 4-5 seconds of cranking, stop and wait 3-4 minutes, then try again. Repeat several times until the vehicle starts.
  5. If the vehicle starts, turn the device booster switch counter-clockwise to the Off position.
  6. Disconnect clamps in reverse sequence to connecting: For negative grounded system, disconnect negative (-) black clamp first, then positive (+) red clamp. For positive grounded system, disconnect positive (+) red clamp first, then negative (-) black clamp. Keep clamps away from the vehicle battery.
  7. Replace the clamps in their storage holders.

? NOTE: Excessive engine cranking can damage the vehicle starter motor. If the engine turns but fails to start after several attempts, another problem may be involved. Discontinue cranking until the issue is determined and corrected.

LED Light & Emergency Flasher Operation

? NOTE: LED light and emergency flasher functions operate in sequence. The mode depends on the last selected function. You may need to cycle through modes to achieve the desired lighting.

Power Inverter Operation

⚠️ CAUTION: Only operate the 120 Volt AC device and inverter in a clear, dry area.

⚠️ CAUTION: Provided with integral protection against overloads. Do not expose to rain. To prevent fire, do not cover or obstruct ventilation openings. Overheating may result. The output is not sinusoidal and has significant harmonic distortion. This unit may produce arcs or sparks; do not install in compartments containing batteries or flammable materials. For continued protection against fire or electric shock, replace only with the same type and rating of fuse.

USB Operation

Unit Battery Hand Generator Operation

? NOTE: Do not exceed the hand generator pull-handle maximum cord length of 30 inches.

? NOTE: The device battery charge level will vary. You may need to continue cranking until the battery reaches a charge level adequate for jump starting a vehicle.

Compressor Operation

To Inflate Plastic Inflatables (Balls, Air Mattresses, Rubber Rafts, etc.):

  1. Remove the valve cap from the inflatable valve stem.
  2. Connect the compressor air-hose nozzle (A) to the inflatable valve stem (B) and turn the locking thumb-lever (C) down. Connect the appropriate valve stem adapter (D) if needed.
  3. Ensure the air-hose nozzle and adapter (if used) are properly seated.
  4. Insert the air-hose nozzle with adapter (if needed) into the inflatable air valve stem as far as practical.
  5. Press the compressor power switch (E) to the On [⏻] position.
  6. Monitor pressure on the compressor air-pressure gauge (F). When desired pressure is reached, press the compressor power switch to the Off [ ] position. Unlock the air-hose nozzle thumb-lever by lifting it up.
  7. Recap the inflatable air valve stem.
  8. Stow the air-hose back into the device storage compartment (G).

To Inflate Tires:

  1. Remove the valve cap from the tire air valve stem.
  2. Ensure the air-hose nozzle locking thumb-lever is in the up position. Use the valve stem adapter if necessary.
  3. Insert the compressor air-hose nozzle (A) onto the tire air valve stem (B), ensuring it is pushed on as far as possible and seated properly. Press down the locking-thumb lever (C) to engage.
  4. Press the compressor power switch (E) to the On [⏻] position.
  5. If the tire is completely flat, raise the vehicle using a recommended jack and jack stands before inflating.
  6. Monitor pressure on the compressor air-pressure gauge (F). It is recommended to use a separate air gauge to check actual tire inflation pressure.
  7. Press the compressor power switch Off [ ] when the desired tire air pressure is reached.
  8. Disconnect the air-hose nozzle from the tire valve stem by lifting the locking thumb-lever to the Up position. Remove any air-hose nozzle adapter.
  9. Recap the tire air valve stem.
  10. Stow the air-hose back into the device storage compartment (G).

⚠️ CAUTION: Do not over inflate! Check the item being inflated for the manufacturer's maximum recommended inflation pressure. Most tires are properly inflated between 24-35 PSI. Some truck & bicycle tires require 40 PSI or more.

Recharging Operation

⚠️ WARNING: Do not charge the device on a boat, boat ramp, or docks, as electrical cords and outlets could cause severe electrical shock if wet.

⚠️ CAUTION: Ensure any electrical outlet in a potentially wet or moist area is protected by a Ground Fault Interrupt switch.
