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.
