Associated Equipment 6512 - Manual (Page 3)

21. ASSEMBLY INSTRUCTIONS
Attach the handle to the charger using the four screws provided.
Attach the front leg to the base with the four hex head screws provided.
To attach wheels and axle to the base, tap one axle nut onto the axle with a hammer, slide one wheel onto
the axle with the whitewall facing out. Push the axle through the base, place wheel on opposite side. Tap
axle nut onto the axle with a hammer.
22. OPERATING INSTRUCTIONS
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 CHARGE TIME timer has an OFF position, a CONTINUOUS CHARGE position and a timed charge
range from 0 to 90 minutes.
a. OFF - Always make sure the timer is in the OFF position before connecting or disconnecting the clamps
from the battery. The charger will not charge with the timer in this position.
b. CONTINUOUS CHARGE - This position is used for slow charging or parallel charging and will not turn the
charger off. 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.
23. TO CHARGE BATTERIES
Make connections to the battery per the instructions in previous sections of this manual.
Determine if the battery is 6, 12 or 24 volts and then set the CHARGE VOLTAGE switch to 6V for a 6 volt battery, 12LO for a 12 volt battery or 24V
for a 24 volt battery.
Turn the timer on and read the AMPERES meter.
If a higher rate of charge is desired for charging 12 volt batteries, set the CHARGE VOLTAGE switch to the 12HI position.
Set the timer to the desired minutes charge.
DO NOT USE THE 12V START POSITION TO CHARGE BATTERIES.
24. 12V CRANKING ASSIST
Turn off all the lights and accessories in the stalled vehicle.
Connect the charger to the battery per previous instructions.
Set the CHARGE VOLTAGE switch to the 12HI position.
Charge the battery on 12HI for at least five minutes. Make sure the battery is accepting current before setting charger to 12V START.
Set the switch in the 12V START position. Start the vehicle with the charger connected to the battery.
NOTE: Do not crank the engine more than 20 seconds in any five minute period; excessive cranking may overheat and damage the starter.
DO NOT USE THE 12V START POSITION TO CHARGE BATTERIES.
If the vehicle fails to start, return the CHARGE VOLTAGE switch to the 12HI position.
While waiting for the starter to cool, allow the charger to continue to charge the battery.
Turn the timer to the OFF position before disconnecting the clamps.
25. DIESEL VEHICLES
Diesel engines have special starting requirements due to the high compression required to ignite the fuel mixture. Because of this, the starter
motors have to work harder which requires the battery to deliver a large amount of power for a period of time. Adequate voltage must be supplied
also to insure the glow plug will have enough power to preheat the chamber. When attempting to start a diesel vehicle, always fast charge the
battery at least five minutes. If time permits, charge the battery as long as possible or until the battery reaches 75% state of charge. Make sure the
battery is accepting current before setting charger to 12V START. With the charger "ON" and attached to the battery, attempt to start the vehicle.
Do not crank the engine more than 20 seconds in a five-minute period. While allowing the starter to cool, allow the charger to continue to charge
the battery. If the vehicle has two batteries installed, read the "VEHICLES WITH TWO BATTERIES" section of this manual.
26. VEHICLES WITH TWO BATTERIES
Many diesel vehicles and service vehicles are equipped with two batteries. This is to provide the vehicle with greater starting power capacity or
longer reserve capacity to provide power for accessories. These batteries are wired into a parallel circuit. Because of this, it will take twice as long
to charge these batteries as indicated in the LENGTH OF CHARGE table. If one battery is charged and the other discharged, the discharged
battery should be removed from the vehicle and checked. When attaching the charger to this type of vehicle the charger should be attached to the
battery which is wired closest to the starter. This allows the charger to provide maximum starting power to the starter motor by minimizing the
voltage drop in the engine cables.
27. PARALLEL CHARGING
This charger may be used to parallel charge up to 10 batteries with a bus bar kit, or by using a minimum 6AWG gauge booster cables to connect
the batteries together in parallel.
CAUTION: Do not connect 6 and 12 volt batteries in parallel with each other.
