Personal Safety Precautions; Preparing To Charge - DieHard DH150 Owner's Manual

2. PERSONAL SAFETY PRECAUTIONS

2.1 Consider having someone close enough by to come to your aid when you
work near a lead-acid battery.
2.2 Have plenty of fresh water and soap nearby in case battery acid contacts
skin, clothing, or eyes.
2.3 Wear complete eye protection and clothing protection. Avoid touching eyes
while working near battery.
2.4 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.
2.5 NEVER smoke or allow a spark or flame in vicinity of battery or engine.
2.6 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.
2.7 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.
2.8 Use the charger for charging only 12V LEAD-ACID (STD or AGM) rechargeable
batteries. 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.
2.9 NEVER charge a frozen battery.

3. PREPARING TO CHARGE

3.1 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.
3.2 Be sure area around battery is well ventilated while battery is being charged.
3.3 Clean battery terminals. Be careful to keep corrosion from coming in contact
with eyes.
