Maintenance And Care; Troubleshooting - Sears 47004 Owner's Manual

Maintenance and care
A minimal amount of care can keep your battery
charger working properly for years.
1. Clean the clamps each time you are finished
charging, Wipe off any battery fluid that may have
come in contact with the clamps to prevent
corrosion.
2. Coil the input and output cords neatly when
storing the charger. This will help prevent acci-
dental damage to the cords and charger.
3. Occasional cleaning of the case with a soft cloth will
keep the finish shiny and help prevent corrosion.
