60 AMP: For brief, high output charging. Follow BOOST CHARGE ratings (min/max, On/Off times) on charger’s front label. Refer to Quick Reference Guide for more details.

200 AMP: For automotive engine starting/cranking assist only. Follow ENGINE START ratings (min/max, on/off times) on charger’s label. Refer to the Quick Reference Guide and paragraph 7.4 for more details.

WARNING: At higher AMP rates, it becomes easier to boil and overcharge the battery. do not leave the charger unattended. Refer to the battery manufacturer’s charging instructions. Use the Charging Time Chart on the Table of Contents page, or the calculation in Section 12, to determine how long to charge. Do not leave on boost charge any longer than necessary or damage to battery will result.

7.4ENGINE START

The ENGINE START setting provides a high current suitable for crank-assist/starting a vehicle that will not start due to a discharged battery. Use the step-by-step instructions of the Quick Refer- ence Guide or use the following procedure. With the rate selector switch set to a fast charge (not boost) setting (40 AMP), charge battery for 5 minutes. After 5 minutes of charge, select the EN- GINE START position (200 AMP), set the timer to the HOLD position. Attempt to start the engine using the ignition key.

If the engine fails to start within 3 to 5 seconds, stop cranking. Return charger to the fast charge setting (40 AMP), and charge battery for another 5 minutes.

If the engine fails to start after a second or third attempt, disconnect the charger. Before replacing the battery, use a battery tester to test it.
