f Read all instructions and cautions printed on the
battery charger, battery and vehicle or equipment
using battery.
f Use the charger for charging lead-acid batteries only
such as those used in cars, trucks, motorcycles,
boats, etc. It is not intended to supply power to a
low-voltage electrical system or to charge dry-cell
batteries commonly used in household appliances
such as radios, toys, camera, etc. Charging dry-cell
batteries may cause them to burst and cause injury to
persons and damage to property.
f Use of an attachment not recommended by the
battery charger manufacturer may result in the risk of
fire or electrical shock.
f Do not disassemble charger. Take it to a qualified
service professional if service or repair is required.
Incorrect assembly may result in fire or electrical shock.
f To reduce risk of electrical shock, unplug the charger
from the outlet before attempting any maintenance or
f Do not expose charger to rain or snow.
f Never charge a frozen battery. If battery acid
becomes frozen, bring battery to a warm area and
allow it to thaw before you begin charging.
f Never touch the battery clamps together when the
charger is on. This may cause a spark.
f Never operate a charger if it has received a hard
blow, been dropped or otherwise damaged. Take it to
a qualified professional for inspection.
f Never pull out the plug by the cord when unplugging
the charger as this may cause damage to the cord or plug.


f Make sure that someone is within range of your voice
to come to your aid if needed while you work with or
are near a lead-acid battery.
f Wear complete eye and clothing protection when
working with lead-acid batteries.
f Avoid touching your eyes while working with a battery.
f Have plenty of fresh water and soap nearby for use in
case battery acid contacts your eyes, skin or
clothing. If this happens, wash immediately with soap
and water then get medical attention.
f Never smoke or allow an open spark or flame in
the vicinity of the battery or engine. Batteries
generate explosive gases.
f Take care not to drop any metal tool or object onto
the battery. This may result in a spark or short
circuit across the battery or another electrical device
that may cause an explosion.
f Remove all personal metal items, such as rings,
bracelets, necklaces and watches from your body
while working with a lead-acid battery. A battery can
produce a short circuit current high enough to weld
such objects to metal, causing a severe burn.
f Never attempt to charge a frozen battery.
f Never overcharge a battery.
f Always operate the battery charger in an open, well-
ventilated area.


Plugging it in
Your charger requires a 3-pin, grounded 220V AC electrical
wall outlet receptacle installed according to local codes
and ordinances.
Warning! Never alter AC cord or plug provided. If it
does not fit the outlet, have a proper outlet installed by a
qualified electrician. Improper connection can result in a
risk of fire or electric shock.
Warning! Do not operate the charger if it has a
damaged power cord or plug. Have the cord replaced.
Using an extension cord
The use of an extension cord is not recommended. If an
extension cord must be used, follow these guidelines:
f Make sure that the pins on the charger's power cord
fit firmly into the extension cord and that the extension
cord fits firmly into the receptacle.
f Check that the extension cord is properly wired and in
good electrical condition.
f Make sure that the wire size is large enough for its
length and for the AC ampere rating of the charger, as
specified in the chart below.

Charger location

f Do not expose charger to rain or snow.
f Locate the charger as far away from the battery being
charged as the cables will permit.
f Be sure to position the power cord to prevent it from
being stepped on, tripped over or damaged.
f Never place charger directly above battery being
charged. Gases from the battery will corrode and
damage the charger.
f Never set a battery on top of a charger.
f Never allow battery acid to drip on charger.
f Always charge a battery in a well-ventilated area.
