12.CALCULATING CHARGE TIME

Find your battery’s rating on the chart below, 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.

CCA = Cold Cranking Amps RC = Reserve Capacity Ah = Amp Hour

NR means that the charger setting is NOT RECOMMENDED.

13.MAINTENANCE INSTRUCTIONS

13.1After use and before performing maintenance, unplug and disconnect the battery charger (see sections 6, 7 and 8).

13.2Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips, cords, and the charger case.

13.3Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the battery clips.

13.4Servicing does not require opening the unit, as there are no user-serviceable parts.

13.5All other servicing should be performed by qualified service personnel.

14.Moving and STORAGE INSTRUCTIONS

14.1Store the charger unplugged, in an upright position. The cord will still conduct electricity until it is unplugged from the outlet.

14.2Store inside, in a cool, dry place.

14.3Do not store the clips on the handle, clipped together, on or around metal, or clipped to cables.

14.4If the charger is moved around the shop or transported to another location, take care to avoid/prevent damage to the cords, clips and charger. Failure to do so could result in personal injury or property damage.
