II) IMPORTANT SAFETY INSTRUCTIONS
1. SAVE THESE INSTRUCTIONS -- This manual contains important safety and
operating instructions for the Phase Three CE Battery Charger.
2. Before using this battery charger, read all instructions and cautionary markings
on (1) the battery charger (2) the battery, and (3) any product powered by the battery.
3. CAUTION -- To reduce the risk of injury, charge only 6 cell (12 volt models) or 12
cell (24 volt models) gel-cell or lead-acid rechargeable batteries. Other types of
batteries may burst, causing personal injury and damage.
4. Do not expose charger to rain or spray.
5. Use of an attachment not recommended or sold by NEWMAR may result in a risk
of fire, electric shock or injury to persons.
6. To reduce the risk of damage to the electric plug and cord (if plugged into an a.c.
outlet), pull by plug rather than cord when disconnecting the charger.
7. Make sure the cord is located so that it will not be stepped on, tripped over, or
otherwise subjected to damage or stress.
8. An extension cord should not be used unless absolutely necessary. Use of an
improper cord could result in a risk of fire and electric shock. If an extension cord
must be used, make sure:
A)That pins on the plug of the extension cord are the same number, size and shape
as those on the plug of 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 a.c. ampere rating of the Phase Three
Charger. Refer to the SPECIFICATIONS SECTION to determine the full load input
current of your Phase Three Charger, then use the chart on the following page to
determine the correct gauge wire for any extension cord used.

9. Do not operate the charger with a damaged cord or plug; replace them
immediately.
10. Do not operate the charger if it has received a sharp blow, been dropped, or
otherwise damaged; take it to a qualified serviceman.
11. Do not disassemble the charger; take it to a qualified serviceman when service
or repair is necessary. Incorrect reassembly may result in a risk of electric shock
and fire.
12. To reduce the risk of electric shock, disconnect the charger from a.c. source
before attempting any maintenance or cleaning.
WARNING--RISK OF EXPLOSIVE GASES
1. WORKING IN THE 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
BEFORE INSTALLING AND USING YOUR CHARGER, YOU READ THIS MANUAL
AND FOLLOW THE INSTRUCTIONS EXACTLY.
2. To reduce the risk of battery explosion, follow these instructions and those
published by the battery manufacturer and by the manufacturer of any equipment
you intend to use in the vicinity of the battery. Review cautionary markings on these
products and on the engine.
PERSONAL PRECAUTIONS
1. Someone should be within range of your voice or close enough to come to your
aid when you work near a lead-acid battery.
2. Have plenty of fresh water and soap nearby in case battery acid contacts skin,
clothing or eyes.
3. Wear complete eye protection and clothing protection. Avoid touching your eyes
while working near a battery.
4. If battery acid contacts skin or clothing, wash immediately with soap and water. If
battery acid enters the eye, immediately flood the eye with running cold water for at
least 10 minutes and get medical attention immediately.
5. NEVER smoke or allow a spark or flame in the vicinity of the battery or engine.
6. Be extra cautious to reduce the risk of dropping a metal tool onto the battery. It
might spark or short-circuit the battery or other electrical part and cause an explosion.
7. 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.
8. Use the battery charger for charging gel-cell or flooded lead-acid batteries only.
It is not intended to supply power to a low voltage electrical system other than in a
starter-motor application. Do not use the 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.
