General Safety Precautions
1. IMPORTANT SAFETY INSTRUCTIONS. IT IS OF UTMOST
IMPORTANCE THAT BEFORE USING YOUR CHARGER,
YOU READ THIS MANUAL AND FOLLOW THE SAFE-
TY AND OPERATING INSTRUCTIONS EXACTLY. SAVE
THESE INSTRUCTIONS.
Risk of explosive gases
Batteries generate explosive gases during normal
operation, and when discharged or charged.
1.1 To reduce risk of battery explosion, follow these safety
instructions and those published by the battery manu-
facturer and the manufacturer of any equipment you
intend to use in the vicinity of a battery. Review caution-
ary marking on these products and on the engine, and
on the vehicle or equipment containing the battery.
Charging a non-rechargeable battery may
cause the battery to burst.
To reduce the risk of injury, only charge rechargeable
lead-acid type batteries including maintenance-free,
low-maintenance, or deep-cycle batteries.
If you are uncertain as to the type of battery you are
attempting to charge, or the correct procedure for
checking the battery’s state of charge, contact the seller
or battery manufacturer.
1.2 Use of an attachment not recommended or sold by the
battery charger manufacturer may result in a risk of re,
electric shock, or injury to persons.
1.3 To reduce risk of damage to the electric plug and cord,
pull by the plug rather than by the cord when discon-
necting the charger.
1.4 Position the AC and DC leads to avoid tripping over
them and to prevent damage by hood, doors, or moving
engine parts; protect from heat, oil, and sharp edges.
1.5 Do not operate the charger if it has received a sharp
blow, been dropped or otherwise damaged in any way;
take it to a qualied service center.
1.6 Do not disassemble charger; take it to a qualied service
center when repair is required. Incorrect reassembly
may result in a risk of electric shock or re.
1.7 To reduce risk of electric shock, unplug the charger from
the AC outlet before attempting any maintenance or
cleaning. Turning o the controls will not reduce this
risk.
Remove marine “boat” batteries and charge
them on shore.
Charging marine batteries on-board requires spe-
cially designed equipment for marine use.
1.8
Connect and disconnect the battery leads only when
the AC supply cord is disconnected.
1.9
Do not overcharge the battery.
1.10
Charge the battery in a dry, well-ventilated area.
1.11
Never place articles on or around the charger, or locate
the charger in a way that will restrict the ow of cooling
air through the cabinet.
1.12
An extension cord should not be used unless absolutely
necessary. (See paragraph 4.3.)
1.13
Have a damaged cord or plug replaced immediately.
1.14
Do not expose the charger to rain or snow.
Personal Precautions
2.1 Always have someone within range of your voice, or
close enough to come to your aid, when working around
lead acid batteries.
2.2 Have plenty of fresh water and soap nearby in case bat-
tery acid contacts skin, clothing or eyes.
2.3 Wear complete eye protection, clothing protection, and
wear rubber soled shoes. Place damp cloth over battery
to protect against acid spray. When ground is very wet
or covered with snow, wear rubber boots. Avoid touch-
ing eyes while working near battery.
2.4 If battery acid contacts skin or clothing, wash imme-
diately with soap and water. If acid enters the eye, im-
mediately ush with cold running water for at least 10
minutes, and seek medical attention.
2.5 NEVER smoke or allow a spark or ame in vicinity of a
battery or engine.
2.6 Be extra cautious to reduce risk of dropping a metal tool
onto the battery. It might spark or short circuit the bat-
tery or other electrical part that may cause an explosion.
2.7 Before working with a lead-acid battery, remove per-
sonal metal items such as rings, bracelets, necklaces,
watches, etc. A lead-acid battery can produce a short
circuit current high enough to weld such items causing
a severe burn.
Safety Guidelines
Non-rechargeable batteries may burst when
charging causing personal injury and damage.
To avoid electrical shock or burn, never alter the char-
ger’s original AC cord and plug. Disconnect plug from
outlet when charger is idle.
The charger is not intended to supply power to a
low-voltage electrical system other than applications
using rechargeable, lead-acid type batteries. Do not
use the battery charger for charging dry-cell batteries
commonly used with home appliances. These batteries
may burst and cause personal injury and property
damage.
2.8 NEVER charge a frozen battery; thaw it out rst.
Preparing To Charge The Battery
3.1
If it is necessary to remove the battery from vehicle to
charge it, always remove the grounded terminal from the
battery rst. Make sure all accessories in the vehicle are
o, so as not to cause an arc.
3.2
Be sure the area around the battery is well ventilated
while the battery is being charged. Gas can be forcefully
blown away by using a piece of cardboard or other non-
metallic material as a fan.
3.3
Clean the battery terminals. Be careful to keep corrosion
from coming into contact with your eyes.
3.4 Add distilled water in each cell until the battery acid
reaches the level specied by the manufacturer. This
helps purge excessive gas from the cells. Do not overll.
For a battery without caps, carefully follow the manufac-
turer’s recharging instructions
3.5 Study all battery manufacturer’s specic precautions
such as removing or not removing cell caps while charg-
ing and recommended rates of charge.
3.6 Determine the voltage of the battery by referring to the
car owner’s manual and make sure that the output volt-
age selector switch is set at the correct voltage. If the
charger has an adjustable charge rate, charge the bat-
tery initially at lowest rate. If the charger has only one
voltage, verify that the battery voltage matches the volt-
age of charger.
For a charger not having an output voltage selector
switch, determine the voltage of the battery by referring
to car owner’s manual and make sure it matches the
output rating of the battery charger.
Grounding & Power Cord Connections
4.1 The charger must be grounded to reduce risk of
electric shock. The charger is equipped with an electric
cord having an equipment grounding conductor and
a grounding plug. The plug must be plugged into an
outlet that is properly installed and grounded in accor-
dance with all local codes and ordinances.
Hazardous voltage.
An improper connection can result in
electric shock
To avoid electrical shock or burn, never alter
the charger’s original AC cord and plug. Dis-
connect plug from outlet when charger is idle.
IF THE PLUG DOES NOT FIT THE OUTLET, HAVE
A PROPER OUTLET INSTALLED BY A QUALIFIED
ELECTRICIAN.
4.2
This battery charger is for use on a nominal 230-volt cir-
cuit.
Hazardous voltage.
An improper connection can result in
electric shock
Before using an adapter be certain the center
screw of the outlet plate is grounded. The rigid
ear or lug extending from the adapter must be
connected to a properly grounded outlet. Make
certain it is grounded. If necessary, replace the
original screw that secures the adapter ear or
lug to the cover plate and make the ground
connection to the grounded outlet.
4.3 An extension cord should not be used unless absolutely
necessary. Use of an improper extension cord could re-
sult in a risk of re and electric shock. If an extension
cord must be used, make sure:
a. that the pins on plugs of the extension cord are the
same number, size, and shape as those of the plug
on the charger;
b. that the extension cord is properly wired and in
good electrical condition;
c. that the wire size is large enough for the AC
ampere rating of charger.
