IMPORTANT SAFETY INSTRUCTIONS
1.
SAVE THESE INSTRUCTIONS.
This manual contains im-
portant safety and operating instructions for the battery charger
MODEL MC9640. You may need to refer to these instructions at a
later date.
2.
CAUTION.
To reduce risk of injury, charge only wet cell, lead
-
acid, automotive type rechargeable batteries. Other types of batter-
ies may burst causing personal injury and property damage.
3.
Do not expose the charger to rain or snow if specifically warned on
the unit not to do so.
4.
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.
5.
To reduce the risk of damage to the electric plug and cord, pull by
the plug rather than the cord when disconnecting the charger.
6.
An extension cord should not be used unless absolutely necessary.
Use of an improper extension cord could result in a risk of fire and
electric shock. If an extension cord must be used, make sure:
a.
That the pins on the plug of extension cord are the same number,
size, and shape as those of the plug on the charger.
b.
That the extension cord is properly wired and in good condition.
c.
If the length of the extension cord is less than 25 feet, use a 18AWG
cord, if 50 feet
-
14AWG, 100 feet
-
12AWG, 150 feet
-
10AWG.
7.
Do not operate the charger with damaged cord or plug. Replace the
cord or plug immediately.
8.
Do not operate the charger if it has received a sharp blow, been
dropped, or otherwise damaged in any way; take it to a qualified
serviceman.
9.
Do not disassemble the charger unless you are qualified to work on
electrical products. If not, take it to a qualified serviceman when
service or repair is required. Incorrect reassembly may result in risk
of electric shock or fire.
10.
To reduce the risk of electric shock, unplug the charger from the
outlet before attempting any maintenance or cleaning. Turning off
the controls will not reduce this risk.

WARNING
-
RISK OF EXPLOSIVE GASES
a.
WORKING IN VICINITY OF A LEAD
-
ACID BATTERY IS DANGER-
OUS. 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.
To reduce the risk of battery explosion, follow these instructions,
those published by the battery manufacturer, and manufacturer of
any equipment you intend to use in vicinity of the battery. Review
cautionary markings on these products and on the engine.
12.
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 touch-
ing eyes while working near battery.
d.
If battery acid contacts skin or clothing, wash immediately with soap
and water. If acid enter eyes, immediately flood eyes with running
cold water for at least 10 minutes and get medical attention
immediately.
e.
NEVER smoke, or allow a spark or flame in the vicinity of the battery
or engine.
f.
Be extra cautious to reduce risk of dropping a metal tool onto the
battery. It might spark or short
-
circuit the battery or other electrical
parts that may cause an explosion.
g.
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.
h.
Use this charger for charging a LEAD
-
ACID battery only. It is not
intended to supply power to a low
-
voltage electrical system other
than in an automotive application. Do not use this battery charger for
charging dry
-
cell batteries that are commonly used with home appli-
ances. These batteries may burst and cause injury to persons and
damage to property.
i.
NEVER charge a frozen battery.
13.
PREPARING TO CHARGE
a.
If necessary to remove battery from vehicle to charge, always re-
move the grounded terminal from the battery first. Make sure all
accessories in the vehicle are off, so as not to cause an arc.
b.
Be sure the area around the battery is well ventilated while the bat-
tery 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 the battery terminals. Be careful to keep corrosion from com-
ing in contact with eyes.
d.
Add distilled water in each cell until battery acid reaches level speci-
fied by the battery manufacturer. This helps purge excessive gas
from cells. Do not overfill. For a battery without cell caps, carefully
follow the manufacturer's recharging instructions.
e.
Study all battery manufacturer's specific precautions such as remov-
ing or not removing the cell caps while charging and the recommend-
ed rates of charge.
f.
Determine voltage of the battery by referring to the car owner's man-
ual and make sure that the output voltage selector switch is set at the
correct voltage. If the charger has adjustable charge rate, charge the
battery initially at the lowest rate.
14.
CHARGER LOCATION
a.
Locate the charger as far away from the battery as the DC cables
permit.
b.
Never place the charger directly above the battery being charged;
gases from the battery will corrode and damage the charger.
c.
Never allow battery acid to drop on the charger when reading the
specific gravity, or filling the battery.
d.
Do not operate the charger in a closed
-
in area, or restrict ventilation
in any way.
e.
Do not set a battery on top of the charger.
15.
DC CONNECTION PRECAUTIONS
a.
Connect and disconnect the DC output clamps only after setting the
charger switch to the OFF position and removing the AC cord from
the electric outlet. Never allow the clamps to touch each other.
b.
Attach the DC clamps to the battery post and twist or rock back and
forth several times to make a good connection. This tends to keep
the clamps from slipping off the terminals and helps to reduce the
risk of sparking.
