Safety
2
Basic principles for safe operation
NOTE
The brake resistor (1) is installed differently
depending on the battery group. The build-up
of heat in the area around the brake resistor
is harmless. The safety valve (2) opens when
the battery is subjected to over pressure or
catches fire.
All lithium-ion batteries are associated with the
risk of a fire starting, of the battery exploding
and of the battery causing chemical burns.
When used as intended, no hazardous
substances escape from the closed tray and
contact with toxic substances will not occur.
There is a risk of contact only in the event of
incorrect use (mechanical, thermal, electrical)
that leads to activation of the safety valve
or to the housing cracking. As a result, the
electrolyte fluid may leak out, the electrode
material may react with humidity/water,
or battery venting/a fire/or an explosion
can occur, depending on the surrounding
circumstances. The position of the safety
valve (2) on the battery depends on the battery
group.
Touching live components can lead to an
electric shock, which can have thermal or
paralysing effects. The latter can cause ven-
tricular fibrillation, cardiac arrest or respiratory
paralysis, leading to death.
If a battery combusts, the resulting smoke or
vapours can cause irritation of the eyes, skin
and respiratory system.
Permissible lithium-ion batteries
– Use only lithium-ion batteries that have
been approved by STILL for use with this
truck. The dimensions of the battery must
precisely correspond to the dimensions
of the battery frame in the truck. The
installation of a smaller battery or a larger
battery poses a risk to the stability of the
truck.
– In addition, follow the operating instructions
provided by the battery manufacturer. The
lithium-ion battery must only be operated
