Harbor Freight Tools 92775 Battery Charger User Manual


 
1. Charging Current Selector (1): The Charging Current Selector is used for
selecting a charging current of either 0.25 AMPs, 0.50 AMPs, or 0.90 AMPs
depending upon the 12 volt battery that is to be charged. Use a digital voltmeter
(not included) to determine the voltage of the battery. Check the battery
manufacturer’s recommended charging current. Then, set the Charging
Current Selector to the appropriate Amperage. (See Figure D.)
2. Power On (2): When illuminated, the Power On feature indicates the Battery
Charger is on and ready for use. (See Figure D.)
3. Battery Charging (3): After properly connecting the Charger Clamps to the
battery, selecting the correct charging current, and turning on the Batter Charger,
the Battery Charging feature will illuminate indicating proper functioning of the
Battery Charger. If the Battery Charging feature
does not
illuminate, the voltage
of the battery is below 9 volts, and the battery
will not
charge. (See Figure D.)
4. Battery Charged (4): When illuminated, the Battery Charged feature indicates
the battery is fully charged and may then be disconnected from the Battery
Charger. (See Figure D.)
5. Low Battery (5): When illuminated, the Low Battery feature indicates the battery
connected
will not
be charged as its voltage is below 9 volts. The battery should
be recycled according to local guidelines. (See Figure D.)
6. Power Switch (6): Always properly connect the Charger Clamps to the battery,
and select the correct charging current
before
turning the Power Switch to its
“ON” position. Once the battery(s) is charged, turn the Power Switch to its
“OFF” position.
Then
disconnect the Charger Clamps, and remove the
battery(s). (See Figure D.)
7. Charger Clamps: Never allow the Red and Black Charger Clamps to touch
each other or the same metal object. Always connect the Black Charger Clamp
of the Charger to the negative (--) terminal on the battery. Always connect the
Red Charger Clamp of the Charger to the positive (+) terminal on the battery.
When connecting the Charger Clamps to the terminals on a battery, always
connect the Red Charger Clamp first, then connect the Black Charger Clamp.
When disconnecting the Charger Clamps, always disconnect the Black Charger
Clamp first, then disconnect the Red Charger Clamp. Make all Charger Clamp
connections before plugging the Charger’s Power Cord Plug into a 120 volt,
grounded, electrical outlet and turning on the Power Switch.
8. Internal 12 Volt Relay (8): The Battery Charger features an internal 12 Volt
Relay to protect the Battery Charger from a short circuit and reverse polarity.
The 12 Volt Relay will not connect the battery to the Battery Charger unless the
battery voltage is more than 9 volts and connected to the proper polarity.
