Operating Instructions
Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this
manual including all text under subheadings therein before set up or use of this product.
TO PREVENT SERIOUS INJURY:
Assemble charger according to Assembly Instructions before use.
DO NOT PLUG IN CHARGER UNTIL DIRECTED TO DO SO.

Timer Dial:
The Timer prevents over-charging while
allowing a battery the needed time to obtain a satisfactory
charge. To set the Timer, you must know the size of
battery in ampere hours or reserve capacity in minutes,
and the state of charge. The state of charge can be
obtained using a battery load tester (not included).
For example, the average size automotive battery at 50%
charge will require 1 to 1-1/2 hours of charging at 40
amp rate to reach full charge state. For the same battery
with the Timer set to maximum, overcharging will occur.
Slight
overcharging should not harm a battery that was
otherwise in good condition. When the state of charge is
unknown, start out with a timer setting of one hour or less.
Hold:
(on Timer Dial)
This sets the charger for
continuous operation. Use for long-period charging,
such as when the lowest charge rate is selected.
WARNING! TO PREVENT SERIOUS INJURY
AND FIRE: Monitor charging and stop
charge when battery is fully charged.
Setting Dial:
Use this to set the
voltage/amperage output.
Ammeter:
The ammeter indicates amount of current
measured in amperes that is drawn from battery.
For example, in 40 amp charge rate a typical discharged
battery will initially draw approximately 40 amps.
As battery continues to charge, current will taper to
15 to 20 amps at full charge. When cranking an engine,
starter motor draws up to 200 amps. The meter needle
will register to extreme left side during 2 amp charge
rate, indicating minimal activity because the meter
doesn’t have the resolution to display such low rates.
When a battery is close to being dead or has a
very low charge, it will want to draw more current.
When a dead or low battery is charged, the charger’s
ammeter will register at high end. As the battery charges,
the reading will move down toward the low end,
resting on zero, when battery is fully charged.
Do not depend on reading ammeter to approximate
how long charging will take. Even at full charge,
ammeter will still provide as much as 50% of charger’s
output rating. Sometimes conditions such as a cold
battery, a sulfated battery, or a deeply discharged
Lead Calcium battery may cause ammeter to read near
a full charge when charging process is only beginning.
Note:
The ammeter shows the amount of current
being drawn from the charger. It does not
show what the charger is capable of delivering.
When the battery is fully charged and registering
zero on the ammeter, a small charge will continue to
move from the charger to the battery. If the charger
is not disconnected from the battery, eventually
heat build up will cause the battery acid to boil and
overcharge the battery causing damage to the battery.
Monitor battery charging progress constantly and if
battery gets warm, stop charging it immediately.
