OPERATING INSTRUCTIONS

CAUTION: The charger must be fully assembled before operating. Refer to "Assembly
Instructions," page 6 for instructions.
The Professional Charger and Starter models CBC 7600 and CBC 7700 charge lead-acid
batteries. You can use the chargers to:
• charge a discharged battery
• perform an engine start to a discharged battery
The CBC 7700 produces a higher current than the CBC 7600 for the normal charge, fast charge,
and engine start. It also contains a voltmeter.
