Batteries generate explosive hydrogen gas, even during normal operation.
Peoplehavebeeninjuredbybatterypartsflyinginanexplosion.Theycanexplode
under normal operating conditions, such as starting your car. They can explode
under abnormal conditions, such as jump starting, or if short circuited by a tool.
They can explode in a parked car or sitting on a table.
To help reduce the risk of these dangers and injury, it is of the utmost importance
that each time before using your charger, you read and understand this manual,
and any warnings and instructions by the battery manufacturer. Follow these
instructions exactly.
TO HELP REDUCE THIS RISK:
1. Wear Personal Protective Equipment
•ALWAYSwearcompleteeyeprotection(THATPROTECTSEYESFROMALL
ANGLES).
2. Avoid Flames and Sparks Near Battery and Fuel
•ALWAYS keep flames, matches, lighters, cigarettes or other ignition sources
away from battery.
•DO NOT put flammable material on or under charger. DO NOT use near
gasoline vapors.
•ALWAYS plug charger into an electrical outlet AFTER all connections have
been made..
•Atool touchingboth batteryposts orbattery postand carmetal partsis ashort
circuitand will spark.Whenusing metaltoolsonor nearbatterybeextra cautious
toreduce riskof shortcircuit,possibly causinga batteryexplosion.DO NOT drop
a tool on battery.
3. Reduce Explosive Gas (hydrogen)
•Before connecting charger, ALWAYS add water to each cell until battery acid
covers plates to help purge extra gas from cells. DO NOT overfill. Battery acid
expandsduringcharge.Afterchargingfilltolevelspecifiedbybatterymanufacturer.
Fora batterywithout removable caps(maintenance freebattery), carefully follow
manufacturer's instructions on charging.
•Some sealed maintenance free batteries have a battery condition indicator. A

not charged or jump started.
•Charge battery with caps in place. Most U.S. batteries are made with flame
arrestingcaps.DONOTprycapsoffsealedbatteries.Placewetclothonbatteries
with non-flame arresting caps.
•Be sure area around battery is well ventilated before and during charging
process. NEVER charge in a closed-in or restricted area.
4. Stay Away From Battery When Possible
•NEVER put face near battery.
•ALWAYS locate charger as far from battery as DC cables permit.
•ALWAYS keep other people away from the battery. They are not wearing
safety glasses like you are.
5. Avoid Contact With Battery Acid
•Battery posts may have acid corrosion. DO NOT get corrosion in your eyes.
Avoid touching eyes while working near battery.
•ALWAYS use a battery carrier. Carrying a battery by hand may put pressure
on its ends, causing acid to be forced out vent caps.
•ALWAYS have plenty of fresh water and soap nearby in case battery acid
contacts eyes, skin or clothing. If battery acid contacts skin or clothing, wash
immediately with soap and water. If acid enters eye, immediately flood eye with
cold running water for at least fifteen (15) minutes and get medical help
immediately.
•Inverycoldweatheradischargedbatterymayfreeze.NEVERchargeafrozen
battery. Gases may form, cracking the case, and spray out battery acid.
6. Avoid Overcharging Batteries
•The nonautomatic (manual) battery charger model can overcharge a battery
if left connected for an extended period of time, resulting in loss of water and
creation of hydrogen gas.
7. Follow Other Manufacturers' Recommendations
•Before using charger, read all instructions for, and caution markings on: (1)
charger, (2) battery, and (3) related product using battery. Follow their
recommended rate of charge.

DANGER!
RISK OF BATTERY EXPLOSION FROM HYDROGEN GAS. MAY RESULT
IN BLINDNESS, SERIOUS INJURY, PERMANENT DISFIGUREMENT AND
SCARRING.
ELECTRICAL WARNINGS
DANGER!
RISK OF ELECTRICAL AND FIRE HAZARD. MAY RESULT
IN DEATH, SERIOUS INJURY, SHOCK OR BURNS.
TO HELP REDUCE THIS RISK:
This charger, like all electrical products, MUST be treated with respect. Follow
these instructions to reduce electrical hazard risk.

1. PROPER GROUNDING AND AC POWER CONNECTION
•Charger MUST be grounded to reduce risk of electric shock. 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
installedandGROUNDEDinaccordancewithalllocalcodesandordinances.
Ifyoueverfeelevenaslightshockfromthisoranyelectricalappliance,stop,walk
away. Turn off electricity to outlet, and have it inspected by an electrician. You
may have a dangerous, improperly wired outlet.
•DANGER-NEVERalterACpowercordorplugprovided- if it willnot fit outlet,
have proper outlet installed by a qualified electrician or proceed as shown in the
illustration below. Improper connection can result in a risk of an electric shock.
This battery charger is for use on a nominal 120 volt circuit (common household
current), and has a grounding plug as illustrated. A temporary adapter may be
used, USA only, to connect this plug to a two-pole receptacle, as shown, if
properlygroundedoutletisnotavailable.The temporary adaptershould beused
only until a properly grounded outlet can be installed by a qualified electrician.
•DANGER - Before using adapter as illustrated below, be certain that center
screw of outlet plate is grounded. The green colored rigid ear or lug extending
from adapter MUST be connected to a properly grounded outlet - make certain
it is grounded. If necessary, replace original outlet cover plate screw with a
longer screw that will secure adapter ear or lug to outlet cover plate and make
ground connection to grounded outlet.
2. Remove Jewelry
•ALWAYS remove personal metal items (such as rings, bracelets, necklaces
and watches) when working with a battery. A short circuit through one of these
items can melt it causing a severe burn.
ALWAYS assume that any
battery might explode
when you least expect it.
Wear safety glasses for
your protection.
