General Conditions of Warranty
Instead of the statutory warranty time period of 2 years, HEINE will grant a
guarantee of 5 years from the date of the consignment of the goods ex works,
concerning its equipment (excluding disposables, e.g. bulbs, single-use articles,
and rechargeable batteries).
The guarantee covers irreproachable workmanship, on condition of the proper
use of the equipment and the observation of the operating instructions. During
the warranty- and guarantee time period, errors and deficiencies arising on the
equipment will be rectified free of charge, in so far as such are evidenced by
defective materials, processing and/or constructional errors. Should buyer complain
of a material deficiency during the warranty time period, then the onus of proof is
always to be on the orderer, that the product was defective already upon receipt
of the goods. The statutory warranty and the guarantee do not apply to loss or
damage caused by wear and tear, negligent use, the non-employment of origi-
nal HEINE components and/or spares (in particular bulbs, as these have been
especially developed for HEINE instruments in accordance with the following
criterions: colour temperature, useful service life, safety, optical quality and per-
formance. The statutory warranty and the guarantee do not apply to interventions
by persons not authorised by HEINE or when the operating instructions are not
observed by the customer. Any modification of a HEINE product with parts or
additional parts which do not conform to the original HEINE specification will
invalidate the warranty for the correct function of the product and further invalidate
any warranty claims which result from such a change or modification. Further
claims, in particular claims for replacement of loss or damage, which are expe-
rienced otherwise than directly on the HEINE product itself, are hereby excluded.
