NOTE: This charger is equipped with an auto-start feature. It will not supply
current to the battery clips until a battery is properly connected. Unlike tradi-
tional chargers, the clips will not spark if touched together.
USING THE QUICK-DISCONNECT CABLE CONNECTORS
Connect any of the three output cable assemblies to the charger in seconds.

NOTE: Never connect the clamp and ring terminal connectors together for use
in other applications, such as external battery or other power source charging,
or to extend the output cable length, as reverse polarity and/or overcharge
conditions will occur.
50 amp Battery Clips
Connect the end of the 50 amp battery clips cable Quick-Connect to the 1.
charger.
Follow the steps in sections 6 and 7 to connect the output clips to the 2.

Permanent Ring Connectors
The ring connectors permanently attach to the battery providing easy access
to quickly charge your battery. This application is appropriate for motorcycles,
lawn tractors, ATVs and snowmobiles.
To permanently attach to a battery, loosen and remove each nut from 1.

Desulfation Mode
If the battery is left discharged for an extended period of time, it could become
sulfated and not accept a normal charge. If the charger detects a sulfated
battery, the charger will switch to a special mode of operation designed for
such batteries. If successful, normal charging will resume after the battery is
desulfated.Desulfationcouldtakeupto8hours.Ifdesulfationfails,charging
willabortandtheCHECKBATTERY (red)LEDwillblink.
Aborted Charge
If charging can not be completed normally, charging will abort. When charging
aborts,thecharger’soutputisshutoff,andtheCHECKBATTERY (red)
LED will blink. To reset after an aborted charge, either disconnect the battery or
unplug the charger.
CALCULATING CHARGE TIMES13.
This charger adjusts the charging time in order to charge the battery com-
pletely,efcientlyandsafely.
Thisbatterychargerhasaratedoutputof2and4amperes.Thisoutputwill
vary with the age and condition of the battery being charged. If the battery has
only been slightly discharged, it can be charged in less than a few hours. The
same battery will take longer to charge if it is very weak.

MAINTENANCE INSTRUCTIONS14.
Before performing maintenance, unplug and disconnect the battery charger 14.1
(seeSections6,7and8).
After use, unplug the charger and use a dry cloth to wipe all battery corro-14.2
sion and other dirt or oil from the terminals, cords, and the charger case.
Ensure that all of the charger components are in place, securely attached 14.3
and in good working condition, including the plastic boots on the battery
clips.
Servicing does not require opening the unit, as there are no user-service-14.4
able parts.
