Battery acid is caustic. Do
not allow it to come into
contact with skin, eyes or
clothing.
Wear suitable protective
clothing, especially
gloves, apron and
faceguard.
Wear eye protection.
Rinse any acid spills
immediately with clear
water. Contact a
physician if necessary.
Keep children away.
Follow the instructions in
this Operator’s Manual.
Batteries contain materials that can harm the
environment if disposed of improperly. Large
12-volt storage batteries contain lead.
Recycling of batteries is the preferred method
of disposal. Many states (USA only) or
provinces (Canada only) require sellers of
batteries to accept old batteries for recycling.

Warning!
Failure to follow these instructions can
result in severe injury or death.
Never lean over batteries while connecting.
You might get injured.
Battery fluid contains sulfuric acid. Do not
allow this fluid to come in contact with
eyes, skin or clothing. In case it does,
immediately flush affected area with water
and seek medical help if necessary.
A battery will also produce hydrogen gas,
which is flammable and explosive. Keep
flames or sparks away from battery, avoid
improper connection of jumper cables,
smoking etc.
G
Warning!
Do not place metal objects on the battery
as this could result in a short circuit.
Use leak-proof batteries only to avoid the
risk of acid burns in the event of an
accident.
Take care that you do not become statically
charged, e.g. by wearing synthetic clothing
or rubbing against textiles. For this reason,
you also should not pull or push the battery
over carpets or other synthetic materials.
Never touch the battery first. First touch
the outside body of the vehicle in order to
release any possible electrostatic charges.
Do not rub the battery with rags or cloths.
The battery could explode if touched due to
electrostatic charge or due to spark
formation.

The battery is a Valve-Regulated Lead
Acid (VRLA) battery, also referred to as
“fleece” battery.
Such batteries do not require topping-up of
the electrolyte level. VRLA batteries
therefore do not have cell caps and the
battery cover is non-removable. Do not
attempt to open the battery as otherwise
the battery will be damaged.
Even though VRLA batteries do not require
topping-up of the electrolyte level and
cannot be opened to check the electrolyte
level, the battery condition must be
checked periodically by performing a
battery conductance test. Refer to
Maintenance Booklet for battery condition
testing intervals.
The factory-equipped VRLA battery is leak-
proofed. Only use a battery as replacement
that has the same security features and is
