• With the charger unplugged and
the switch OFF, connect the positive
(red) charger cable to the positive (+)
battery terminal and then the negative
(black) charger cable to the negative
(-) battery terminal.
• Set the charger for the correct
voltage and charging rate. Then plug
the charger in and turn the switch
ON.
• When charging is completed, turn
the charger OFF, unplug it and then
disconnect negative and then
positive cables. Reconnect the
positive and then the negative
battery cables
Slow Charging
Slow charging passes a relatively small amount (5-7 amps) of current through
a battery for a long period (14-16 hours or longer).
Slow charging is preferred to fast charging if time is available, but a sound
battery will not be damaged by proper fast charging. Older batteries respond
better to slow charging.
Before charging, clean and ll the battery to recommended level. If battery
is to remain in the loader, remove cables to prevent damage to machine
electronics.
NOTICE! Watch battery temperature during charging. If it exceeds 125°F,
lower the charge rate. Temperatures in excess of 125°F will cause serious
battery damage.
Remove battery from charger when charged because overcharging is
harmful.
When installing the battery, be sure you connect the ground strap to the
negative battery post.
Fast Charging
Fast charging sends a relatively heavy initial current (50-60 amps) through the
battery. This will impart a fairly good charge in one to two hours.
