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.

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!

Charger should be grounded to reduce the 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 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 in 

FIGURE 1 (A). This plug should be used in a grounded outlet. The plug

pins must fit the receptacle (outlet).

ADAPTER: A temporary adapter, as shown in FIGURE 1 (B) and (C), may

be used to connect the charger plug to a two pole receptacle (outlet), as

shown in FIGURE 1 (B).
NOTE: The  temporary  adapter  should  be  used  only  until  a  properly

grounded outlet can be installed by a qualified electrician.

DANGER: Never alter the AC cord or plug provided. If it will not fit outlet, have a proper outlet installed by a qualified electrician. Improper connection can

result in a risk of an electrical shock. 

DANGER: Before using an adapter, as illustrated, be certain that the center screw of the outlet plate is grounded. 

The green-colored rigid ear or lug extending from the adapter must be connected to a properly grounded outlet. Make certain it is grounded. If neces-

sary, 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.

Never place charger directly above the battery being charged, 

gases from battery could damage the charger.

Never allow battery acid to drip on the charger when reading 

specific gravity of filling battery.

Never operate charger in a closed in area, or restrict ventila-

tion in any way.

Do not set battery on top of the charger.

1.  Make sure you have a 12 volt lead-acid battery and select 

appropriate battery charger switch. 

2.  Clean battery terminals. Take care to keep corrosion from

coming in contact with your eyes.

3.  If required, add distilled water in each cell until battery acid

reaches levels specified by battery manufacturer. This helps

purge excessive gas from cells. Do not overfill. For a battery

without cell caps, carefully follow manufacturer's recharging

instructions.

4.  Study all battery manufacturer's specific precautions, such

as removing or not removing cell caps while charging, and

recommended rates of charge.

5.  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.

6.  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.

7.  A marine (boat) battery must be removed and charged on

shore. To charge it on board requires equipment specially

designed for marine use.
