IMPORTANT SAFETY INSTRUCTIONS

SAVE THESE INSTRUCTIONS – This manual contains important safety and operating

instructions for battery charger model P/N 022-0227.

Do not expose charger to rain or snow.

Use of an attachment not recommended or sold by the battery charger manufacturer may

result in a risk of fire, electric shock, or injury to persons.

To reduce risk of damage to electric plug and cord, pull by plug rather than cord when

An extension cord should not be used unless absolutely necessary. Use of improper

extension cord could result in a risk of fire and electric shock. If an extension cord must

That pins on plug of extension cord are the same number, size, and shape as those of

That extension cord is properly wired and in good electrical condition; and

That wire size is large enough for ac ampere rating of charger as specified in Table 1.

Length of Cord, Feet /Meters 25/7.6 50/15.2 100/30.5 150/45.7

Do not operate charger with damaged cord or plug – replace the cord or plug

Do not operate charger if it has received a sharp blow, been dropped, or otherwise

damaged in any way; take it to a qualified serviceman.

Do not disassemble charger; take it to a qualified serviceman when service or repair is

required. Incorrect reassembly may result in a risk of electric shock or fire.

To reduce risk of electric shock, unplug charger from outlet before attempting any

maintenance or cleaning. Turning off controls will not reduce this risk.

10) WARNING – RISK OF EXPLOSIVE GASES.

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 YOU

FOLLOW THE INSTRUCTIONS EACH TIME YOU USE THE CHARGER.

To reduce risk of battery explosion, follow these instructions and those published by

battery manufacturer and manufacturer of any equipment you intend to use in

vicinity of battery. Review cautionary marking on these products and on engine.

Consider having someone close enough by to come to your aid when you work near

Have plenty of fresh water and soap nearby in case battery acid contacts skin,

Wear complete eye protection and clothing protection. Avoid touching eyes while

If battery acid contacts skin or clothing, wash immediately with soap and water. If

acid enters eye, immediately flood eye with running cold water for at least 10

minutes and get medical attention immediately.

NEVER smoke or allow a spark or flame in vicinity of battery or engine.

Be extra cautious to reduce risk of dropping a metal tool onto battery. It might spark

or short-circuit battery or other electrical part that may cause explosion.

Remove 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.

Use charger for charging Six cell Lead-Acid/AGM OR Three cell Lithium Iron

Phosphate (LiFePO4) Batteries only. Do not use battery charger for charging dry-

cell batteries that are commonly used with home appliances. These batteries may

burst and cause injury to persons and damage to property.

NEVER charge a frozen battery.

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

Be sure area around battery is well ventilated while battery is being charged.

Clean battery terminals. Be careful to keep corrosion from coming in contact with

Add distilled water in each cell until battery acid reaches level specified by battery

manufacturer. Do not overfill. For a battery without removable cell caps, such as

valve regulated lead acid batteries, carefully follow manufacturer's recharging

Study all battery manufacturers specific precautions such as removing or not

removing cell caps while charging and recommended rates of charge.

Determine voltage of battery by referring to car owner's manual and make sure that

output voltage selector switch is set at correct voltage. Do not use the battery

charger unless battery voltage matches the output voltage rating of the charger.

Locate charger as far away from battery as dc cables permit.

Never place charger directly above battery being charged; gases from battery will

corrode and damage charger.

Never allow battery acid to drip on charger when reading electrolyte specific gravity

Do not operate charger in a closed-in area or restrict ventilation in any way.

Do not set a battery on top of charger.

14) DC CONNECTION PRECAUTIONS

Connect and disconnect dc output clips only after setting any charger switches to

"off" position and removing ac cord from electric outlet. Never allow clips to touch

Attach clips to battery and chassis as indicated in 15(e), 15(f), and 16(b) through

15) FOLLOW THESE STEPS WHEN BATTERY IS INSTALLED IN VEHICLE. A SPARK

NEAR BATTERY MAY CAUSE BATTERY EXPLOSION. TO REDUCE RISK OF A

Position ac and dc cords to reduce risk of damage by hood, door, or moving engine

Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to

Check polarity of battery posts. POSITIVE (POS, P, +) battery post usually has

larger diameter than NEGATIVE (NEG, N,–) post.

Determine which post of battery is grounded (connected) to the chassis. If negative

post is grounded to chassis (as in most vehicles), see (e). If positive post is

grounded to the chassis, see (f).

For negative-grounded vehicle, connect POSITIVE (RED) clip from battery charger

to POSITIVE (POS, P, +) ungrounded post of battery. Connect NEGATIVE (BLACK)

clip to vehicle chassis or engine block away from battery. Do not connect clip to

carburetor, fuel lines, or sheet-metal body parts. Connect to a heavy gage metal

part of the frame or engine block.
