Warranty
Fundamentally, all modifications to the product by third parties
lead to exclusion from the warranty.
Obvious defects must be reported to the vendor in writing immedi-
ately after delivery, no later than one week, but in any case before
processing or installation, otherwise the assertion of a warranty
claim is excluded. A timely dispatch is sufficient to keep the term.
The vendor is to be given an opportunity to check on site. If the
complaint is justified the vendor offers warranty by repair or re-
placement at its own discretion. If the rectification fails, the buyer
may choose to demand reduction of payment or cancellation of
the contract. If there is only a minor lack of conformity, particularly
with only minor defects, the buyer nevertheless has a right of
withdrawal.
If, after failed rectification, the buyer chooses to cancel the
contract due to a defect of title or material defect, they are not
entitled to additionally claim for damages.
If, after failed fulfilment, the buyer chooses compensation, the
goods remain with the buyer, if this is reasonable. The compen-
sation is limited to the difference between the purchase price and
the value of the defective item. This does not apply if the vendor
maliciously causes the breach of contract.
The quality of the goods is only considered as agreed upon with
the product description of the vendor. Public statements, claims
or advertising of the manufacturer do not represent an additional
contractual specification of quality of the goods.
If the buyer receives defective mounting instructions, the buyer
is only obligated to deliver defect-free mounting instructions and
only if the defect to the mounting instructions prevents proper
mounting.
The warranty period is two years and begins upon completion.
Exchange and return of custom products are fundamentally
excluded. The factory conditions of the manufacturing factory
apply to parts not manufactured and processed by the vendor,
which can be viewed by the orderer at the vendor at any time.
Construction and installation parts are delivered according to the
present standard of engineering.
Service life
In general, safety dampers are machine elements that are
designed for emergency stop applications.
Safety shock absorbers can be started up with 100 % stroke utili-
sation with a creep speed of 1/10 of the maximum impact velocity.
The propelling force must be greater than the return force.
Starting at creep speed subjects the sealing elements of the
safety dampers to wear. The wear of seals is largely dependent
upon the operating conditions and the respective application and
its operating parameters.
