CAUTION
Any battery at 1150 specific gravity or lower may readily freeze and should be charged at once.
(6)
Set TIMER to value selected from chart for the state-of-charge of the battery.
(7)
Turn CHARGING RATE switch to the LOW (slow charge) or HIGH (fast charge) position for the voltage of the
battery being charged.
(8)
Be sure that ammeter indicates that charging current is flowing. Ammeter will indicate charging current in
accordance with the battery state-of-charge.
(9)
Refer to table 7-3 and ensure that the voltmeter indicates within prescribed limits.
