MAINTENANCE INSTRUCTIONS 12.
Before performing maintenance, unplug and disconnect battery charger 12.1
(see sections 6.7 and 7.6).
After use, unplug charger and use a dry cloth to wipe all battery corrosion
12.2
and other dirt or oil from terminals, cords, and the charger case.
After every 100 hours or
12.3
whenever you see dust
accumulating on the fan
blades you should clean
both fans using com-
pressed air (as shown).
NOTE: Use the com-
pressed air on the fan
blades only. Do not blow
dirt into the fan shaft or
bearing.
These fans push a lot of air
and are precision balanced.
Excessive dirt and grime
buildup will cause the fan
to be unbalanced and wear out quickly. If the fans fail, the charger may
overheat and the thermal protection of the charger will shut it down.
Servicing does not require opening unit, as there are no user-serviceable
