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 clearing.
Turning off controls will not reduce this risk.
10. WARNING – Risk of explosive gases:
a) 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 each time before using your charger you read
this manual and follow the instructions exactly.
b) 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.
11. Personal Precautions
a) Someone should be within range of your voice or close enough to come to your aid when you work near a lead-
acid battery.
b) Have plenty of fresh water and soap nearby in case battery acid contacts skin, clothing, or eyes.
c) Wear complete eye protection and clothing protection. Avoid touching eyes while working near battery.
d) 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.
e) 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.
f) Remove personal metal items such as rings, bracelets, necklaces, and watches when working with lead-acid
battery. A lead-acid battery can produce a short-circuit current high enough to weld a ring or similar metal items,
causing a severe burn.

g) Use charger for charging above-named battery types 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.
h) NEVER charge a frozen battery
12. Preparing to charge
a) If it is 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.
b) 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.
c) Clean battery terminals. Be careful to keep corrosion from coming in contact with eyes.
d) Add distilled water in each cell until battery acid reaches level specified by battery manufacturer. This helps purge
excessive gas from cell. Do not overfill. For a battery without cell-caps, carefully follow manufacturers recharging
instructions.
e) Study all battery manufacturer‘s specific precautions such as removing or not removing cell caps while charging
and recommended rates of charge.
f) Determine voltage of battery by referring to car owner‘s manual and make sure it matches output rating of battery
charger.
13. Charger location

charged. Gases from battery will corrode and damage charger.
b) Never allow battery acid to dip on charger when reading gravity or filling battery.
c) Do not operate charger in a closed-in area or restrict ventilation in any way.
d) Do net set a battery on top of charger.
14. DC connection precautions
a) 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 each other.
b) Attach clips to battery and chassis as indicated in 15(f), 15(g), 16(c), and 16(d).
15. Follow these steps when battery is installed in vehicle. A spark near battery may cause battery explosion: To
reduce risk of spark near battery:
a) Position ac and dc cords to reduce risk of damage by hood, door, or moving engine part.
b) Stay clear of fan blades, belts, pulleys, and other parts that can cause injury to persons.
c) Plug in the charger to AC mains.
d) Check polarity of battery posts POSITIVE (POS, P, +) battery post usually has larger diameter than NEGATIVE
(NEG, N, -) post.
e) Determine which post of battery is grounded (connected) to the chassis. If negative post is grounded to chassis
(as in most vehicles), see 15(f). If positive post is grounded to the chassis, see 15(g).
f) For negative-grounded vehicles, connect POSITIVE (RED) clip from battery charger to POSITIVE (POS, P, +)
ungrounded post of battery. Connect NEGATIVE (BLACK) clip from battery charger far from battery with chassis
or engine block. Do not connect clip to carburator, fuel lines, or sheet-metal body parts. Connect to a big and thick
chassis or engine block metal piece.
g) For positive-grounded vehicle, connect NEGATIVE (BLACK) clip from charger to NEGATIVE (NEG, N, -)
ungrounded post of battery. Connect POSITIVE (RED) clip from battery charger far from battery with chassis or
engine block. Do not connect clip to carburator, fuel lines, or sheet-metal body parts. Connect to a big and thick
chassis or engine block metal piece.
