Timer

Timer Setting: The timer allows you to set a specified time for charging. After the timer expires, the charger stops charging your battery. The main function of the timer

is to prevent overcharging while allowing a battery time to obtain a satisfactory charge. To properly set the timer,

you must know the size of the battery in ampere hours or reserve capacity in minutes and the state of charge. It

is important that you determine the appropriate state of charge of your battery as specified in Section 12 and set the timer accordingly.

24H (Hold): This position defeats the timer function, allowing for continuous operation. Put the timer in the 24H position when you want to charge more than 2¼ hours.

WARNING Be sure to monitor the charging progress and stop it when the battery is charged. Not doing so may cause damage to your battery or may cause other personal property damage or personal injury. • 6 •
