3.7 Safety information concerning
maintenance and care
Disconnect the vehicle completely from the battery sup-
–
ply during all maintenance and servicing work and
when replacing parts or converting to another function.
Observe the safety inspection pursuant to the applica-
–
ble local provisions for mobile vehicles used for com-
mercial purposes.
Maintenance work may only be carried out by approved
–
customer service outlets or experts in this field who are
familiar with the respective safety regulations.
Do not clean the appliance with a water hose or high-
–
pressure water jet (danger of short circuits or other
damage).

Notes regarding the battery

ATTENTION
Using non-rechargeable batteries is prohibited.
Only use batteries and chargers approved by the manufac-
turer.
Replace batteries with the same battery type only.
Prior to disposal of the vehicle, the batteries must be re-
moved and disposed of in accordance with local regula-
tions.
3.8.1

Safety notes regarding the batteries

Follow accident prevention regulations as well as DIN VDE
0510, VDE 0105 T.1.
Please observe the following warning notes when handling
batteries:
Observe the directions on the battery, in the in-
structions for use and in the vehicle operating
instructions!
Wear an eye shield!
Keep away children from acid and batteries!
Risk of explosion!
Fire, sparks, open light, and smoking not al-
lowed!
Danger of causticization!
First aid!
Warning note!
Disposal!
Do not throw the battery in the dustbin!
DANGER
Risk of fire and explosion!
Do not place tools or similar items on the battery. Risk

of short-circuit and explosion.
Smoking and open flames must be strictly avoided.

Rooms where batteries are charged must have good

ventilation because highly explosive gas is emitted dur-
ing charging.
Danger of causticization!
Use caution with leaking batteries (sulphuric acid may

leak).
Risk of injury!
Ensure that wounds never come into contact with lead.

Always clean your hands after working on batteries.
3.8.1.1 Procedures in the event of unintentional
release of battery acid
When used normally, and when observing the instructions,
lead-acid batteries do not pose any risk.
However, keep in mind that lead-acid batteries contain sul-
phuric acid which can cause chemical burns and corro-
sion.
If there is spillage or, if the battery is leaking, acid is es-

caping, lay down a binding agent such as sand. Do not
let it reach the sewer system, soil or a body of water.
Neutralise the acid with lime/baking soda and dispose

of it according to local regulations.
Contact a waste management company to dispose of

faulty batteries.
Rinse thoroughly with lots of clear water if acid gets into

the eye or comes in contact with the skin.
Then consult a doctor immediately.

Wash off the acid If it comes in contact with the clothes.

Change clothing.

3.8.2 Check and correct the fluid level of the
battery (only for low-maintenance
batteries)
Warning
Regularly check the fluid level in acid-filled batteries.
The acid in a fully charged battery has a specific weight
–
of 1.28 kg/l at a temperature of 20 °C.
The acid in a partially discharged battery has a specific
–
weight between 1.00 and 1.28 kg/l.
The specific weight of the acid must be uniform in all
–
cells.
Unscrew all cell caps.

Take a sample from each cell using the acid tester.

Put the acid sample back into the same cell.

Where fluid level is too low, top up cells to the mark pro-

vided with distilled water.
Charge battery.

Screw in cell caps.
