DANGER. Before using an adapter as illustrated, be certain
that the center screw of the outlet plate is grounded. The
green-colored rigid ear or lug extending from the adapter must
be connected to a properly grounded outlet - make certain it is
grounded. If necessary, replace the original outlet cover plate
screw with a longer screw that will secure the adapter ear or
lug to the outlet cover plate and make ground connection to
grounded outlet.
NOTE: USE OF AN ADAPTER IS NOT ALLOWED IN CANADA. IF A GROUNDING TYPE RECEPTACLE IS NOT AVAILABLE, DO NOT
USE THIS APPLIANCE UNTIL THE PROPER OUTLET IS INSTALLED BY A QUALIFIED ELECTRICIAN.

CHARGE PERIOD
The approximate required time to bring a battery to full charge state depends upon the number of ampere-hours (AH) depleted from the
battery. AH's are determined by multiplying the number of hours times the number of amps supplied by a battery to a load and normally
indicated on the battery. For example, if a load was connected to a battery, which drew 7 amps for a period of 5 hours, the battery will have
supplied 35 AH. The approximate recharge time would then be calculated by dividing the 35 AH depleted from the battery, by the charge
rate of the charger. To allow for tapering of the charge rate add 25 percent to the charge time.
OPERATING INSTRUCTIONS
This automatic battery charger is designed to charge 6 or 12 volt batteries of either conventional or maintenance-free construction. Rated
output current is 10 or 2 DC amps. The 2 ampere setting is better for charging small 12 volt batteries under 20 amp hour size used with
motorcycles, garden tractors, etc. DO NOT TRY TO CHARGE A 6 VOLT BATTERY ON THE 12 VOLT SETTING. When operating this
charger, carefully follow the instructions in sections 17 and 18. When all connections have been made and the charger is connected to AC
power, the meter on the charger will indicate the amount of DC amperes of charge being delivered to the battery. This charging rate will
taper off as the battery comes up to full charge. In automatic chargers the voltage is limited to a preset level to prevent overcharging. The
charge rate drops to a very low pulsating rate to maintain battery charge level. If current is drawn from the battery as in some type of
standby operation, the charger will automatically come on to compensate.
DEEP CYCLE CHARGING - [To charge deep cycle batteries, you must monitor the charging to insure the size battery you are charging
permits the voltage to increase to the preset trickle trip point of the control circuit.] If the battery becomes very warm ( 125EF) or appears
to be bubbling freely charging should be stopped.
POSSIBLE CHARGING PROBLEMS
1. THE METER INDICATOR NEEDLE SWINGS TO THE EXTREME RIGHT SIDE OF THE METER:
This battery charger has been equipped with an automatic reset circuit breaker. This protects the charger from temporary overload
conditions. A severely discharged battery, a battery with shorted cells, or reversed charger connections at the battery will cause this
protective device to operate.
Under these overload conditions, the circuit breaker will open, and when cooled down will reset automatically.
This cycling process can be identified by a clicking sound made during the opening and closing of the circuit breaker.
a. Check for reverse polarity connections.
b. If the battery is severely discharged, the charge meter needle will start to cycle up and down, and will stabilize after 15 or 20 minutes.
c. The battery may have one or more shorted cells. Cycling will start immediately and continue indefinitely. If cycling has not stopped as
outlined in (b), disconnect the charger (AC power cord first) and have the battery tested.
2. THERE IS NO METER READING:
a. Check the switch position.
b. Check the connections to the battery. Be sure the polarity is correct (red clamp to positive). "Rock" the clamps to bite through any dirt
or corrosion. If in a vehicle, be sure the terminals on the battery are clean and tight.
c. Check the AC outlet or extension cord connections, to be sure power is being supplied to the battery charger.
d. One or more cells may be shorted. The thermal switch in the charger may cycle (click on and off).
MAINTENANCE INSTRUCTIONS
This charger requires minimal maintenance. As with any appliance or tool, a few common sense rules will prolong the life of the battery
charger. ALWAYS BE SURE THE CHARGER IS UNPLUGGED BEFORE PERFORMING ANY MAINTENANCE OR CLEANING.
1. Store in a clean, dry place
2. Coil up the cords when not in use.
3. Clean the case and cords with a slightly damp cloth.
4. Clean any corrosion from the clamps with a solution of water and baking soda.
5. Examine the cords periodically for cracking or other damage and have them replaced if necessary.
