teries only. Use of this charger on other batteries could lead to severe
property damage or personal injury.
SAVE THESE INSTRUCTIONS – The MSC-2405 offers a wide range of 1.1
features to accommodate the needs for home or light commercial use.
This manual will show you how to use your charger safely and effectively.
Please read, understand and follow these instructions and precautions

rather than the cord when disconnecting the charger.
An extension cord should not be used unless absolutely necessary. Use 1.6
of an improper extension cord could result in a risk of re and electric
shock. If an extension cord must be used, make sure:
That the pins on the plug of the extension cord are the same number, •
size and shape as those of the plug on the charger.
That the extension cord is properly wired and in good electrical condition.•
That the wire size is large enough for the AC ampere rating of the charger •
as specied in the table in section 8.
Do not operate the charger with a damaged cord or plug; take it to a 1.7
qualied service person. (Call customer service at: 1-800-621-5485.)

before attempting any maintenance or cleaning. Simply turning off the
controls will not reduce this risk.
WARNING – RISK OF EXPLOSIVE GASES.
WORKING IN THE VICINITY OF A LEAD-ACID BATTERY IS DANGER-
• 1 •
OUS. BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION. FOR THIS REASON, IT IS OF UTMOST
IMPORTANCE THAT YOU FOLLOW THE INSTRUCTIONS EACH TIME
YOU USE THE CHARGER.
TO REDUCE THE RISK OF BATTERY EXPLOSION, FOLLOW THESE
INSTRUCTIONS AND THOSE PUBLISHED BY THE BATTERY MANUFACTURER AND THE MANUFACTURER OF ANY EQUIPMENT YOU
INTEND TO USE IN THE VICINITY OF THE BATTERY. REVIEW THE
CAUTIONARY MARKINGS ON THESE PRODUCTS AND ON THE
ENGINE.
PERSONAL PRECAUTIONS2.
Consider having someone close enough by to come to your aid when you 2.1
work near a lead-acid battery.
Have plenty of fresh water and soap nearby in case battery acid contacts 2.2
your skin, clothing or eyes.
Wear complete eye and body protection, including safety goggles and pro-2.3
tective clothing. Avoid touching your eyes while working near the battery.
If battery acid contacts your skin or clothing, wash immediately with soap 2.4
and water. If acid enters your eye, immediately ood the eye with cold running water for at least 10 minutes and get medical attention right away.
NEVER smoke or allow a spark or ame in the vicinity of a battery or 2.5
engine.
Be extra cautious to reduce the risk of dropping a metal tool onto the bat-2.6
tery. It might spark or short-circuit the battery or other electrical part that
may cause an explosion.
Remove personal metal items such as rings, bracelets, necklaces and 2.7
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.
Use this charger for charging a LEAD-ACID battery only. It is not intended 2.8
to supply power to a low voltage electrical system other than in a startermotor application. Do not use this 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.
NEVER charge a frozen battery.2.9
NEVER overcharge a battery.2.10

PREPARING TO CHARGE3.
If it is necessary to remove the battery from the vehicle to charge it, al-3.1
ways remove the grounded terminal rst. Make sure all of the accessories
in the vehicle are off, to prevent arcing.
Be sure the area around the battery is well ventilated while the battery is 3.2
being charged.
Clean the battery terminals before charging the battery. During cleaning, 3.3
keep airborne corrosion from coming into contact with your eyes, nose
and mouth. Use baking soda and water to neutralize battery acid and help
eliminate airborne corrosion. Do not touch your eyes, nose or mouth.
Add distilled water to each cell until the battery acid reaches the level 3.4
specied by the battery manufacturer. Do not overll. For a battery without
removable cell caps, such as valve regulated lead-acid-batteries, carefully
follow the manufacturer’s recharging instructions.
Read, understand and follow all instructions for the charger, battery, 3.5
vehicle and any equipment used near the battery and charger. Study all of
the battery manufacturer’s specic precautions while charging and recommended rates of charge.
Determine the voltage of the battery by referring to the vehicle owner’s 3.6
manual and make sure that the output voltage selector switch is set to the
correct voltage. If the charger has an adjustable charge rate, charge the
battery in the lowest rate rst.
Make sure that the charger cable clips make tight connections.3.7
CHARGER LOCATION4.
Locate the charger as far away from the battery as the DC cables permit.4.1
Never place the charger directly above the battery being charged; gases 4.2
from the battery will corrode and damage the charger.
Do not set the battery on top of the charger.4.3
Never allow battery acid to drip onto the charger when reading the electro-4.4
lyte specic gravity or lling the battery.
Do not operate the charger in a closed-in area or restrict the ventilation in 4.5
any way.
DC CONNECTION PRECAUTIONS5.
Connect and disconnect the DC output clips only after turning the charger 5.1
off and removing the AC plug from the electrical outlet. Never allow the
clips to touch each other.
Attach the clips to the battery and chassis, as indicated in steps 6.5, 6.6 5.2
and 7.2 through 7.4.
