Technical changes

Since we are constantly working on the further development of our products, there may be

deviations between the product and this publication. Therefore, no claims can be derived

from the information, figures and descriptions. For binding information on the specific charac-

teristics of your machine, please contact your service dealer.

Legal information

Please note that only the German operating instructions are the original operating instruc-

tions within the meaning of Directive 2006/42/EC. Operating instructions that are available in

languages other than German are translations of the original German operating instructions.

Please understand that changes to the scope of delivery in terms of form, equipment and

technology are possible at any time.

Dear customer,

Quality is value that pays for itself. Therefore, we apply the highest quality standards to our

products, which are continuously monitored by our in-house quality management and by our

management. Because safety, flawless function, the highest quality and absolute reliability of

our machines in operation are our core competencies for which we stand.

These operating instructions are intended to facilitate getting to know your machine, and pro-

vide you with clear information on safe and proper handling, care and maintenance. There-

fore, please take some time to read the instructions.

These operating instructions are part of the machine. They must be kept in a suitable loca-

tion during the entire service life of the machine and must be accessible to personnel at all

times. Instructions on the basis of existing national regulations on accident prevention, traffic

regulations and environmental protection must be added.

All personnel charged with the operation, maintenance or transport of the machine must

have read and understood these instructions, in particular the safety instructions, before

starting work. Failure to follow these instructions will void the warranty.

If you have any questions regarding the contents of these operating instructions or any other

questions about this machine, please contact your PÖTTINGER service partner.

Timely and conscientious care and maintenance according the established maintenance in-

tervals will ensure operational and traffic safety as well as the reliability of your machine.

Only use original spare parts or spare parts and accessories approved by PÖTTINGER

Landtechnik GmbH. Only the original spare parts approved by us have been tested by us

and thus fulfill the suitable prerequisites for use in your machine. If unapproved parts are

used, the guarantee or warranty claim will be lost. Even after the warranty period has ex-

pired, we recommend using original spare parts to ensure the continuous performance of the

machine.

The product liability law obligates the manufacturer as well as the dealer to hand over in-

structions when selling machines and to train the customer on the machine by referring to the

safety, operating and maintenance instructions. A confirmation in the form of a delivery dec-

laration is required to prove that the machine and the instructions have been handed over

properly. The delivery declaration was enclosed with the machine at the time of delivery.

According to product liability law, every self-employed person and farmer is an entrepreneur.

Entrepreneurial property damage is therefore excluded from liability by PÖTTINGER accord-

ing to product liability law. Property damage within the meaning of product liability law is

damage caused by a machine, but not to it.

The operating instructions are part of the machine, therefore hand them over to the new own-

er when passing on the machine. Train the new owner, and refer the owner to the aforemen-

tioned instructions.

Your PÖTTINGER service team wishes you much success.

Screw tightening torques

This factory standard applies to all metric screws for which no special tightening torque is

specified in the drawing/instructions. The respective strength class can be seen on the screw

head.

• The values specified are nominal values and apply to a head friction coefficient of

IJ=0.14 and a thread friction of IJ=0.125. Slight deviations of the clamping force due to

different friction coefficients may occur. The values listed must be observed with a toler-

ance of ± 10%.

• If the specified tightening torques are used and the friction coefficients used are present,

the screw material is stressed to 90% of the minimum yield strength according to DIN

ISO 898.

• If a special tightening torque is specified for a screw connection, all of these screw con-

nections must be tightened with a torque wrench and the specified tightening torque.
