Read Rules for Safe Operation and Instructions Carefully
Working in vicinity of a lead-acid battery is dangerous. Batteries generate explosive gases during normal
battery operation. For this reason, it is of utmost importance that each time before using your charger, you
read this manual and follow the instructions exactly.
WARNING: Handling the cord on this product or cords associated with accessories sold with this product, will expose you to lead, a
chemical known to the State of California to cause cancer and birth defects or other reproductive harm.
GENERAL BATTERY SAFETY
Wash hands after handling.
1. Before you use your battery charger, be sure to read all
instructions and cautions printed on:
• Battery Charger
• Battery
• Vehicle or unit using battery
2. Use battery charger on LEAD ACID type rechargeable
batteries only, such as used in autos, trucks, tractors,
airplanes, vans, RV's trolling motors, etc. Charger is not
intended to supply power to low-voltage electrical system
other than in an automotive application.
WARNING: Do
cell batteries that are commonly used with home appliances.
These batteries may burst and cause injury to persons and
damage to property.
3. Use only attachments recommended or sold by
manufacturer. Use of non-recommended attachments may
result in fire, electric shock, or injury.
4. When disconnecting the battery charger, pull by the plug
not by the cord. Pulling on the cord may cause damage to
cord or plug.
5. Locate battery power cord so it cannot be stepped on, tripped
over, or subjected to damage or stress.
6. Do not operate charger with damaged cord or plug. Have
cord replaced immediately.
7. Do not operate charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way. Take it to a
qualified professional for inspection and repair.
8. Do not disassemble charger. Take it to a qualified
professional when service or repair is required. Incorrect
reassembly may result in electric shock or fire.
9. To reduce risk of electric shock, unplug charger from outlet
before attempting any maintenance or cleaning.
not use battery charger for charging dry-
10. Do not use an extension cord unless absolutely necessary.
Use of an improper extension cord could result in fire or
electric shock. If an extension cord must be used, make
sure that:
• Pins on plug of extension cord are the same number,
size, and shape as those of plug on charger.
• Extension cord is properly wired and in good electrical
condition.
• Wire size is large enough for AC ampere rating of charger,
as specified below:
Length of cord (feet): 25 50 100 150
AWG size of cord: 18 18 18 16
11. Always charge battery in a well ventilated area.
NEVER operate in a closed-in or restricted area without
adequate ventilation.
WARNING: Risk of explosive gas.
12. Locate charger as far away from battery as DC charger
cables permit.
13. Do not expose charger to rain or snow.
14. NEVER charge a frozen battery. If battery fluid (electrolyte)
is frozen, bring into a warm area to thaw before charging.
15. NEVER allow battery acid to drip on charger when reading
specific gravity or filling battery.
16. NEVER set a battery on top of charger.
17. NEVER place charger directly above battery being charged.
Gases from battery will corrode and damage charger.
18. NEVER touch the battery clips together when the charger
is energized.
19. NEVER crank engine with charger attached to battery, and
120 volt line.

PERSONAL PRECAUTIONS AND SAFETY
1. WARNING: Wear complete eye protection and clothing
protection, when working with lead-acid batteries.
2. Make sure someone is within range of your voice or close
enough to come to your aid when you work with or near a
lead-acid battery.
3. Have plenty of fresh water and soap nearby for use if battery
acid contacts skin, clothing, or eyes. If battery acid contacts
skin or clothing, wash immediately with soap and water.
4. Avoid touching your eyes while working with a battery. Acid
particles (corrosion) may get into your eyes! If acid enters
your eye, immediately flood eye with running cold water for
at least 10 minutes. Get medical attention immediately.
GROUND AND AC POWER CORD CONNECTIONS
Charger should be grounded to reduce risk of electric shock.
Charger is equipped with an electric cord having an equipmentgrounding conductor and a grounding plug. The plug must be
plugged into an outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
This battery charger is designed for use on a nominal 120-volt
circuit and has a grounded plug that looks like the plug illustrated FIGURE 1 (A). This plug should be used in a grounded
outlet. The plug pins must fit the receptacle (outlet).
ADAPTER: A temporary adaptor, as shown in FIGURE 1 (B)
and (C), may be used to connect the charger plug to a two-pole
receptacle (outlet) as shown FIGURE 1 (B).
NOTE: The temporary adapter should be used only until a properly grounded outlet can be installed by a qualified electrician.
5. Remove all personal metal items such as rings, bracelets,
necklaces, and watches when working with a lead-acid
battery. A lead-acid battery can produce a short-circuit
current high enough to weld a ring (or the like) to metal,
causing a severe burn.
6. Take care not to drop a metal tool or other metal onto the
battery. Metal may cause sparking or short circuit the battery
or another electrical devise. Sparking may cause an
explosion.
7. Always operate battery charger in an open well ventilated
area.
8. NEVER smoke or allow a spark or flame in the vicinity of
the battery or engine. Batteries generate explosive gases!

DANGER: NEVER alter the AC cord or plug provided. If it will not fit outlet, have proper outlet installed by a qualified electrician.
Improper connection can result in a risk of an electric shock. DANGER: Before using an adaptor as illustrated, be certain that center
screw of outlet plate is grounded. The green-colored rigid ear or lug extending from adaptor 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.
PREPARING TO CHARGE
1. If necessary to remove battery from vehicle to charge,
always remove grounded terminal from battery first. Make
sure all accessories in the vehicle are off, so as not to cause
an arc.
2. Be sure area around battery is well ventilated while 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. Clean battery terminals. Be careful to keep corrosion from
coming in contact with eyes.
Keep the battery terminals clean and tight. Use terminal
protectors to prevent corrosion.
4. If battery has removable filler vents, check periodically to
make sure battery electrolyte (liquid) covers the plates. If
liquid is down, add water to bring level up. This also helps
purge excessive gas from the cells.
NOTE: DO NOT OVERFILL (OVERFILLING COULD
RESULT IN DAMAGE).
5. Study all battery manufacturer's specific precautions such
as removing or not removing cell caps while charging, and
recommended rates of charge.
6. DO NOT use for
parallel charging. Charger is designed to
charge / maintain one 12 volt battery.
CHARGER LOCATION PRECAUTION
Never place charger directly above battery being charged; gases
from battery could damage charger.
Never allow battery acid to drip on charger when reading specific gravity or filling battery.
Do not operate charger in a closed-in area or restrict ventilation
in any way.
Do not set battery on top of charger.
