IMPORTANT SAFETY INSTRUCTIONS
This manual contains important safety and operating
instructions for
Snap-on
Fleet Battery Charger model
EEBC300A. Refer to the information in this manual often for
safe operation.
Read All Instructions
Read, understand and follow all safety messages and
instructions in this manual and on the test equipment. Safety
messages in this section of the manual contain a signal word, a
three-part message, and, in some instances, an icon.
The signal word indicates the level of hazard in a situation:
• Danger indicates an imminently hazardous situation which, if
not avoided, will result in death or serious injury to the
operator or bystanders.
• Warning indicates a potentially hazardous situation which, if
not avoided, could result in death or serious injury to the
operator or bystanders.
• Caution indicates a potentially hazardous situation which, if
not avoided, may result in moderate or minor injury to the
operator or bystanders.
The three-part message uses three different type styles to
further define the potential hazard.
• Normal type states the hazard.
•Bold type states how to avoid the hazard.
•
Italic type
states the possible consequences of not avoiding
the hazard.
An icon, when present, gives a graphical description of the
potential hazard.

Safety Information
Battery Gases, Charging Preparation and Charger Location
Risk of explosion. Gases produced by a battery are
highly explosive.
• Wear safety goggles and protective clothing, user
and bystander.
• Use charger in an area having at least 4 air
changes per hour.
• Read, understand and follow all instructions for
charger, battery, vehicle and any equipment used
near battery and charger.
• Do not obstruct vents on charger housing.
• Do not smoke, strike a match, place metal tools on
battery or cause a spark in the vicinity of the
battery. When removing battery cables, remove
ground cable first.
• Clean terminals before charging battery. During
cleaning, keep airborne corrosion from eyes, nose
and mouth. Use baking soda and water to
neutralize acid and help eliminate airborne
corrosion.
• Never allow clamps on charger cables to touch
each other.
• Do not expose charger to rain, snow or wet
conditions.
• Do not allow battery gasses or acid to contact
charger cabinet. Do not place charger directly
above or below battery.
• Fill battery to level specified by battery
manufacturer using distilled water.
• Remove or do not remove cell caps while charging
per manufacturer's instructions.
• Make sure charger cable clamps make tight
connections.
Battery explosion can cause injury.
Acid Burns
Battery acid is highly corrosive sulfuric acid.
• Wear safety goggles, user and bystander.
• Wear protective gloves.
• Make sure someone can hear you or is close
enough to provide aid when working near battery.
• Have plenty of fresh water and soap nearby. If
battery acid contacts skin, clothing or eyes, flush
the exposed area with soap and water for 10
minutes. Seek medical help.
• Do not touch eyes while working near battery.
Battery acid can burn eyes and skin.

Safety Information
Grounding, AC Power Cord Connections
and General Charger Use
Risk of electric shock and fire.
• Before connecting power cord to outlet make sure
controls are set to OFF.
• Do not remove or bypass the grounding pin.
• Do not operate charger with damaged cord or
plug. Replace cord or plug immediately.
• Position power cord and charger cables away from
the hood, doors or hot/moving engine parts where
they could be damaged.
• Use extension cord only when absolutely
necessary. An extension cord up to 25 feet must
be 18 AWG, up to 50 feet must be 14 AWG, up to
100 feet must be 12 AWG and up to 150 feet must
be 10 AWG and extension cord plug and charger
plug must have the same number, size and shape
of pins.
• Unplug power cord using plug rather than cord
when disconnecting charger from outlet.
• Charger power cord uses equipment-grounding
conductor and a grounding plug. Plug only into a
three-prong 120 VAC outlet that is correctly
installed and grounded in accordance with all
ordinances and local codes.
• When using an adapter refer to
Figure 1
.
• Unplug power cord from outlet before cleaning or
maintaining charger. Turning off controls will not
reduce this risk.
• Do not operate charger after a sharp impact,
dropping or any other damage. Do not
disassemble charger. Call
Snap-on/Sun
Representative for repairs.
• Use only recommended attachments.
• Do not charge a frozen battery. Do not overcharge
a battery.
• Use charger only for lead-acid automotive
batteries and for automotive cranking assist using
procedure in this manual. Do not use charger for
charging dry-cell batteries.
Electric shock or fire can cause injury.

Safety Information
Refer to
Figure 1.
Use the charger on a nominal 120 VAC
circuit that has a grounding outlet that looks like B. An adaptor
can be used, such as one like E to connect the plug to a two-
pole outlet like C, until a properly grounded outlet can be
installed by a qualified electrician.
Figure 1:
Outlet and Plug Configurations
A – Charger Power Cord Plug
B – Grounded Power Outlet
C – Ungrounded Power Outlet
D – Green Grounding Lug, must be properly
grounded
*
E – Grounding Adaptor
*If necessary, replace original outlet cover plate screw with a
longer screw that will secure adaptor ear or lug to outlet cover
plate, making ground connection to grounded outlet.
Risk of entanglement.
Keep yourself, clothing and battery charger leads
clear of moving parts such as fan blades, pulleys,
hood, and doors.
Moving parts can cause injury.
Thermal Burns
Risk of burns.
Batteries can produce a short-circuit current high
enough to weld jewelry to metal. Remove jewelry
such as rings, bracelets and watches before working
near batteries.
Short circuits can cause injury.

Safety Information
Charging Instructions
Follow the information in this section to help ensure safety when
connecting the charger cables to battery. For additional
information refer to
Battery Charging Procedure
.
Battery in Vehicle
Use this information when charging battery in vehicle.
• Do not charge automotive batteries installed in boats.
Remove the battery and charge on shore. Onboard charging
requires equipment designed for marine use.
• Identify battery terminal polarity.
— Negative terminal may be marked NEG, N or –.
— Positive terminal may be marked POS, P or +.
✓✓
✓✓The positive terminal is usually larger diameter than the
negative terminal on batteries with top terminals.
• Identify system ground.
— Negative ground system has negative terminal connected
to chassis. This is the most common type.
— Positive ground system has positive terminal connected
to chassis.
Negative Ground
• Connect positive charger cable clamp—red—to positive
battery terminal.
• Connect negative charger cable clamp—black—to vehicle
chassis, heavy gauge metal part of frame or engine block,
