Operating Instructions
Jump Starting a Vehicle
The CMXCESM262 is designed to jump start vehicles with up to 10.0L gas engines and 8.0L diesel engines. It is compatible with standard, AGM, gel, and deep-cycle batteries.
- Connect: Ensure the jump starter is sufficiently charged. Connect the red clamp to the positive (+) terminal of the vehicle's battery and the black clamp to a metal part of the vehicle's chassis (away from the battery and fuel lines) or the negative (-) terminal if safe to do so.
- Start: Turn on the jump starter. Attempt to start the vehicle. If the vehicle does not start immediately, wait a few minutes and try again. The device features Schumacher’s Pre-Heating Technology for reliable starts in freezing temperatures and Pre-Boost for deeply discharged batteries.
- Remove: Once the vehicle starts, immediately disconnect the black clamp, then the red clamp, from the vehicle.
