2A Slow charge Rate – Intended for charging small batteries such as  
those commonly used in garden tractors, snow mobiles and motorcycles.  
15A fast and 50A Rapid charge Rate – Use for charging automotive,  
marine and deep-cycle batteries. Not intended for industrial applications.  
250A Engine Start – Provides 250 amps for cranking an engine with a  
weak or run down battery. Always use in combination with a battery.  
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 over charging 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 and set the timer accordingly.  
hold: This position defeats the timer function, allowing for continuous  
operation. 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.  
10 •  
 
Ammeter  
The Ammeter indicates the amount of current, measured in amps, that is being  
drawn by the battery. As a battery takes on a charge, it draws less current from  
the charger. Correspondingly, the meter will show less current being drawn by  
the battery. When the current stops decreasing, the battery is charged. The  
start area of the meter indicates a high rate of current being drawn from the  
charger. When cranking an engine, the meter needle will be at the extreme  
right side of the start area. The 2 amp charge rate may indicate some activity  
on the meter, although the meter does not have the resolution to display this  
low rate.

16. BEfORE RETURNINg fOR REPAIRS  
16.1 When a charging problem arises, make certain that the battery is capable  
of accepting a normal charge. Double check all connections, the A.C. outlet  
for a full 120 volts, the charger clips for correct polarity and the quality of  
the connections from the cables to the clips and from the clips to the battery  
system. The clips must be clean.  
16.2 When a battery is very cold, partially charged or sulfated, it will not draw the  
full rated amperes from the charger. It is both dangerous and damaging to a  
battery to force higher amperage into it than it can effectively use  
in recharging.  
16.3 When an UNKNOWN OPERATING PROBLEM arises, please read this  
complete manual and call the customer service number for information that will  
usually eliminate the need for return.  
If the above solutions do not eliminate the problem, or for information about troubleshooting  
or replacement parts, call toll-free from anywhere in the U.S.A.
