4. Operating Instructions
4.1 Jump Starting a Vehicle
The STANLEY J5CPD can jump-start most 12V vehicle batteries.
- Ensure the vehicle's ignition is off and all accessories are turned off.
- Connect the RED positive (+) clamp to the positive (+) terminal of the vehicle's battery.
- Connect the BLACK negative (-) clamp to a non-moving metal part of the vehicle's chassis, away from the battery and fuel lines. Do not connect to the negative battery terminal directly unless specified by vehicle manufacturer.
- Turn on the "Jump Start" switch on the STANLEY J5CPD unit.
- Attempt to start the vehicle. If it does not start within 5-8 seconds, wait at least 3 minutes before trying again.
- Once the vehicle starts, turn off the "Jump Start" switch on the unit.
- Disconnect the BLACK negative (-) clamp first, then the RED positive (+) clamp.
- Store the clamps securely on the unit.

4.2 Using the Air Compressor
The 120 PSI air compressor is suitable for inflating vehicle tires, bicycle tires, sports balls, and other small inflatables.
- Attach the appropriate nozzle adapter (if needed) to the air hose.
- Securely connect the air hose to the item you wish to inflate.
- Turn on the "Air Compressor" switch on the unit.
- Monitor the pressure on the digital display. The compressor will automatically shut off when the preset pressure is reached (if applicable) or when the maximum pressure is achieved.
- Once the desired pressure is reached, turn off the "Air Compressor" switch.
- Disconnect the air hose from the item.
