Saito ProCharger S Operating Instructions Manual page 13

Safety
Only operate the product in a moderate climate, never in a tropical
climate. Refer to the chapter "Technical data" (see page 26) for
admissible environmental conditions.
Make sure that the charging device is firmly attached to the power
socket. There might otherwise be a danger of injury due to the weight
of the falling product. The device could furthermore be damaged. Do
not use the device, if it has suffered a heavy impact or blow, or if it has
been dropped. In such a case the device must be checked resp. repaired
by an authorised service centre.
Although the charging device features numerous safety functions,
extensive heating of the battery or the device can never be completely
excluded.
Make sure that the device is sufficiently aired throughout the operating
phase.
Never cover up the charging device or the connected battery. Keep a
sufficient distance (at least 10 cm) between the charging device and the
surroundings/wall, in order not to constrict the circulation of air.
Never connect the product immediately to the mains voltage, if it was
transported from a cold to a warm room. The developing condensation
water could lead to malfunctioning or damaging. There is also a risk of
fatal injury from electric shock.
Let the charging device (and the battery) warm up to room tempera-
ture, before you connect the charging station to the mains voltage and
start charging. This can take several hours!
Maintenance, setting and repair work may only be carried out by a
specialist/authorised service centre.
