3. The charger is equipped with an electronic timer. When the battery reaches the
gassing threshold (2.3 V/cell) the timer will activate and run for three hours.
During this period the batteries are in gassing mode. After three hours the
charger will drop the batteries into float mode (2.26 V/cell), indicated by a blinking
LED.
4. To discontinue charging, unplug the extension cord from the power outlet and the
machine.
To extend the life of the batteries, the machine should only be used until the charge
meter reads 20%. Fully discharging the batteries on a regular basis will dramatically
decrease the life of the battery, or cause polarity reversal resulting in complete battery
failure. After the battery reaches 10% of charge remaining, the discharge rate increases
dramatically.
It is normal for the charger to become hot when charging. Do not obstruct the flow of air
around the charger. Do not allow clothing, blankets or other material to cover the
charger. Do not use near fuels, grain, dust, solvents or other flammables.
The battery charger must be grounded to reduce the risk of electric shock. The charger
is equipped with a ground type plug, and it must be plugged into a nominal 115 volt, 60
Hz circuit.
Improper connection of the charger grounding conductor can result in a risk of an
electric shot. Do not use this charger on a two pole ungrounded outlet or attempt to
break off the ground prong for use on a receptacle or extension cord not having a
ground.
To reduce the risk of fire, only charge this machine on circuits provided with a maximum
of 20 ampere branch circuit protection circuit breaker or fuse, in accordance with the
National Electric Code, and all local codes and ordinances.
Even after relatively short periods of charging, about 2-3 hours, the battery indicator
may initially read 100% charge. This is an indication of the surface charge of the battery
and will decrease quickly to the actual percentage of charge while running the machine.
This is normal. To achieve a deeper charge percentage the machine should be left
charging for longer periods of time.
Since there are one sets of four batteries wired in series some cells become uneven
during charge/discharge cycles. At least one a month, perform two charge cycles back-
to-back. This will bring up cells that are lagging behind fully charged cells. This is
important for overall battery performance.
