serviceman when service or repair is required.
Incorrect reassembly may result in a risk of electric
shock or fire.
9. To reduce risk of electric shock, unplug charger from
outlet before attempting any maintenance or cleaning.
Turning off controls will not reduce this risk.

IMPORTANT SAFETY INSTRUCTIONS - READ THESE FIRST
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 eyes while working near battery.
4. 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.
5. NEVER smoke or allow a spark or flame in vicinity of
battery or engine.
6. 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.
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 charger for charging LEAD-ACID battery only. It
is not intended to supply power to a low voltage
electrical system other than in a starter-motor
application. 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.
9. NEVER charge a frozen battery.
