General Charging Notes

Fan: The charger is designed to control its cooling fan for efficient operation. Consequentially, it is normal for the fan to start and stop when maintaining a fully charged battery. Keep the area near the charger clear of obstructions to allow the fan to operate efficiently.

Voltage: The voltage displayed during charging is the charging voltage and is usually higher than the battery’s resting voltage.

13.CALCULATING CHARGE TIME

Use the table below to more accurately determine the time it will take to bring a battery to full charge. First, identify where your battery fits into the chart.

NR means that the charger setting is NOT RECOMMENDED.

Find your battery’s rating on the chart, and note the charge time given for each charger setting. The times given are for batteries with a 50% charge prior to recharging. Add more time for severely discharged batteries.

14.MAINTENANCE INSTRUCTIONS

14.1After use and before performing maintenance, unplug and disconnect the battery charger (see Sections 6, 7 and 8).

14.2Use a dry cloth to wipe all battery corrosion and other dirt or oil from the terminals, cords, and the charger case.

14.3Ensure that all of the charger components are in place and in good working condition, including the plastic boots on the battery clips.

14.4Servicing does not require opening the unit, as there are no user-serviceable parts.

15.STORAGE INSTRUCTIONS

15.1Store the charger unplugged, in an upright position. The cord will still conduct electricity until it is unplugged from the outlet.

15.2Store inside, in a cool, dry place.

15.3Store the clips on the fiberglass clamp rod. Do not store them on the handle, clipped together, on or around metal, or clipped to the cables.
