On arrival, immediately check the product and its packaging for damage in tran-
sit. If damage from transit is identified, the necessary steps must be taken
involving the carrier within the specified period.
CAUTION! Risk of personal injury and material damage!
Incorrect transport and temporary storage can cause damage to the product

mechanical damage during transport and temporary storage.

mum of 6 months.
