IMPORTANT SAFETY INSTRUCTIONS
SAFETY PRECAUTIONS FOR WORKING IN THE VICINITY OF A BATTERY
1)
Batteries generate explosive gases during normal operation. Use in well-ventilated area.
2)
Consider having someone close enough or within the range of your voice to come to your
aid when you work near a battery.
3)
Do NOT smoke, strike a match, or cause a spark in vicinity of battery or engine. Avoid
explosive gas, flames and sparks.
4)
Remove all personal jewelry, such as rings, bracelets, necklaces, and watches while
working with a vehicle battery. These items may produce a short-circuit that could cause
severe burns.
5)
Be extra cautious to reduce risk of dropping a metal tool onto the battery. It might spark
or short-circuit a battery or other electrical hardware which may cause an explosion or fire.
6)
Wear complete eye protection, hand and clothing protection. Avoid touching eyes while
working near a battery.
7)
Study all battery manufacturer’s specific precautions such as removing or not removing
cell caps while charging and recommended rates of charge.
8)
Clean battery terminals before connected with the charger. Be careful to keep corrosion
from coming in contact with eyes.
9)
When it is necessary to remove a battery from vehicle to charge, always remove grounded
terminal from battery first. Make sure all accessories in the vehicle are off in order to prevent
an arc.
10)
It is NOT intended to supply power to an extra-low-voltage electrical system or to charge
dry-cell batteries. Charging dry-cell batteries may burst and cause injury to persons and
property.
11)
NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
12)
If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If
electrolyte enters eye, immediately flood eye with running clean cold water for at least 15
minutes and get medical attention immediately.
SAFETY PRECAUTIONS FOR USING THE CHARGER
1)
Do NOT place the charger in the engine compartment or near moving parts or near the
battery; place as far away from them as DC cable permits. NEVER place a charger directly
above a battery being charged; gases or fluids from battery will corrode and damage charger.
2)
Do NOT cover the charger while charging.
3)
Do NOT expose to rain or wet conditions.

4)
Connect and disconnect DC output only after setting AC cord from electric outlet.
5)
Use of an attachment not recommended or sold by the manufacturer may result in a risk
of fire, electric shock or injury to persons.
6)
Do not overcharge batteries by selecting the wrong charge mode.
7)
To reduce the risk of damage to electric plug and cord, pull by the plug rather than the
cord when disconnecting charger.
8)
To reduce risk of electric shock, unplug charger from outlet before attempting any
maintenance or cleaning.
9)
Operate with caution if the charger has received direct hit of force or been dropped.
Have it checked and repaired if damaged.
10)
Any repair must be carried out by the manufacturer or an authorized repair agent in
order to avoid danger.
CONNECTING TO THE BATTERY
1)
Identify polarity of battery posts. The positive battery terminal is typically marked by
these letters or symbol (POS,P,+). The negative battery terminal is typically marked by these
letters or symbol (NEG,N,-).
2)
Do not make any connections to the carburetor, fuel lines, or thin metal parts.
3)
Identify if you have a negative or positive grounded vehicle. This can be done by
identifying which battery post (NEG or POS) is connected to the chassis.
4)
For a negative grounded vehicle (most common): connect the RED POSITIVE battery
clamp first to the positive battery terminal, then connect the BLACK NEGATIV battery
clamp to the negative battery terminal or vehicle chassis.
5)
For a positive grounded vehicle (very uncommon): connect the BLACK NEGATIV
battery clamp first to the negative battery terminal, then connect the RED POSITIVE battery
clamp to the positive battery terminal or vehicle chassis.
6)
When disconnecting, disconnect in the reverse sequence, removing the negative first (or
positive first for positive ground systems).
NOTICE: If battery clamps are reversely connected to battery terminals, the ERROR LED
will be on. Exchange the battery clamps to solve this problem.

ABOUT CN-4000
1)
The CN-4000 is designed for charging all types of 6V lead-acid and 12V lead-acid
batteries, including WET (Flooded), MF (Maintenance-Free), EFB (Enhanced Flooded
Battery), GEL, AGM (Absorbed Glass Mat) batteries. It is suitable for charging battery
capacities from 1.2 to 130 Amp-Hours and maintaining all battery sizes.
2)
Built-in intelligent microprocessor makes charging faster, easier and safer.
3)
This charger has safety features, including spark proof, protection for reverse polarity,
short circuit, overheat and overcharge.
4)
It has auto-memory, which returns to last selected mode when restarted (except Repair
Modes).
5)
When the battery level indicator bars are flashing, it is on charging; when 5 bars are solid,
the charging is completed. But do NOT break the connection immediately. It will
automatically switches from full charge to maintenance status without overcharging or
damaging the battery.
6)
It is important to keep in mind the distance to the battery. The DC cable length from the
charger is approximately 75 inches (1900mm).
