MAINTENANCE INSTRUCTIONS

13.1 After use and before performing maintenance, unplug and disconnect the battery
charger (see sections 6, 7 and 8).
13.2 Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery clips,
cords, and the charger case.
13.3 Ensure that all of the charger components are in place and in good working condition,
for example, the plastic boots on the battery clips.
13.4 Servicing does not require opening the unit, as there are no user-serviceable parts.
13.5 All other servicing should be performed by qualified service personnel.

MOVING AND STORAGE INSTRUCTIONS

until it is unplugged from the outlet.

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