20. LENGTH OF CHARGE
a. Test the battery for state of charge. Do not charge if it is over 75% charged or the battery is determined to be defective.
b. Set beginning amps charge rate for size of battery and state of charge per charts
c. Charge for length of time per charge,
d. Discontinue charge when the specific gravity of electrolyte reaches 1.260 or above. A temperature compensating hydrometer should
be used for this reading. Discontinue charge if the battery begins to gas excessively or when the temperature of the electrolyte
reaches approximately 120EF. Do not overcharge batteries. Overcharging results in excessive water loss and eventual damage to
the battery.

CAUTION
- This battery charger must be fully assembled before operating. Failure to do so may result in risk of injury.
USE OF INSTRUMENT PANEL:
The MINUTES CHARGE timer has an OFF position, a CONTINUOUS CHARGE position and a timed charge range from 0
to 90 minutes.
a. OFF"F" - Always make sure the timer is in the OFF "O" position before connecting or disconnecting the clamps from
the battery. The charger will not charge with the timer in this position.
b. CONTINUOUS CHARGE"I" - This position is used for slow charging or parallel charging, the timer will not shut the charger OFF while
in this position. Do not use this position for fast charging.
c. 0 to 90 MINUTES TIMED CHARGE - The timer will automatically turn the charger off at the end of the pre-set charging time. Turn the
timer past 20 before setting the desired time.
TO CHARGE BATTERIES
Make the connections to the battery per the instructions in the previous sections.
Determine if the battery is 6, 12 or 24 volt and then set the CHARGE VOLTAGE switch to 6 for a 6 volt battery, 12 for a 12 volt battery or
24 for a 24 volt battery. Turn the timer on. The Ammeter will show the amount of current delivered to the battery. Length of charge
should be per the above chart and instructions.
Turn the switch to OFF "F" and remove the AC power cord from the electric outlet before disconnecting the DC clamps.
BOOST STARTING
Turn off all lights and accessories in the stalled vehicle.
Connect the charger to battery per previous instructions. Charge the battery for at least five minutes before attempting to start the
vehicle.
Start the vehicle with the charger connected to the battery. Follow the duty cycle on the unit.
NOTE: Do not crank the engine more than 20 seconds in any five minute period; excessive cranking may overheat and damage the
starter.
If the vehicle fails to start, while waiting for the starter to cool, allow the charger to continue to charge the battery.
