Service life
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 immediately 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 replacement 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 compensation 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.
In general industrial shock absorbers are machine elements that are subject to wear. Wear parts such as seals, pressure chambers
and pistons are excluded from the general warranty. The wear of seals is largely dependent upon the operating conditions and the
respective application and its operating parameters.
In general with this model of industrial shock absorber with grooved ring wiper seal system an average service life of three to
five million load changes can be expected. Adverse environmental and operating conditions can significantly reduce the expected
service life.
