11.0    WARRANTY 
 

Hans Leffer GmbH guaranties for the period of 12 months or for 2000 working hours 
(whatever occurs first) from the day of completed commissioning, that the machine is 
free of defects resulting from design, material and/or manufacturing. 
If the machine is going to show defects in design, material and/or manufacturing 
during the warranty period while used regularly, the defect will be corrected at the 
manufacturer’s discretion. 
Regularly use of the machine also means that all service- and maintenance intervals 
are observed and that the machine is used in accordance with the instructions given 
in the manual. 
If the manufacturer repairs the machine during the warranty period, the warranty for 
repaired/replaced parts or sections of the machine, will be prolonged for maximum 6 
months. 
If during the repair of the machine, machine parts are to be replaced and therefore 
disassembled, all disassembled parts will become the property of Hans Leffer GmbH. 
Parts like motors, pumps, valves, cylinders and electrical / electronical devices, 
whether they are apparently defective or not, must not be opened for inspection, 
alteration or repair. 
In these cases Hans Leffer GmbH reserves the right to declare the warranty null and 
void. 
Components may only be opened with prior written authorization from Hans Leffer 
GmbH and claims will only be accepted if sufficient evidence of the defect in 
question is sent to  
Hans Leffer GmbH.   
Hans Leffer GmbH reserves final judgment on all such cases. 
Above mentioned items shall be returned to Hans Leffer GmbH only with prior 
acceptance from Hans Leffer GmbH. It is the buyer's responsibility to return the 
components under warranty freight pre-paid for inspection. 
If the component found to be defective, it will be replaced or repaired free of charge. 
Components without the original factory seals or which were opened without 
the agreement of Hans Leffer GmbH, will not be accepted. 
The warranty is limited to the replacement or repair of defective products and does 
not include labor, consumables or other costs incurred in removing, dismantling or 
re-installing such items.
