There is a lot of information to provide, so I have posted several pictures with basic details to give you an overview of the saw's capabilities. It is a rare model with a feeder (single piece) of 0-2000mm, as well as repeat cutting of 2000-9999mm. Automatic zeroing before cutting. CNC saw head with automatic rotation of +/-60 degrees, 2 types of lubrication, emulsion, and direct spray. Option to direct the cut piece to an ejector for small pieces, as well as a chain ejector with a function for lowering longer and heavier pieces. I haven't included this in the pictures as it is not installed, but the saw also comes with a set of protective guards with safety barriers and a large number of spare parts. The complete documentation is original and is linked to the machine's serial number, making installation easy and straightforward. Ijdpfxeyk Inpe An Nstk Problem explanation: the saw is connected to the electrical power supply, and each individual function (and there are many) is fully operational. The problem arises during automatic operation; the most likely cause is the program parameters themselves (it uses the Windows platform). I haven't been able to find a suitable programmer who can learn on my machine. Possible solution: I contacted the saw manufacturer, and they directed me to their authorized service provider, so I have their contact information, which I can provide to the future buyer. The estimated cost of repair in Serbia is between 3000-5000 EUR. If you are closer to Germany or the Czech Republic, this cost will be significantly lower. So, there are two price categories: if you buy the machine in its current condition, the price is as advertised. If I resolve the problem, the price will be considerably higher. The advertised price includes professional dismantling and loading onto a truck (a rather important, and not inexpensive, item). Transportation is at the buyer's expense. I hope I have clarified the current condition of the machine. Due to a change in business activities, the saw is surplus to production. Happy shopping!

It has been stored in our warehouse for a few years and was used to print photos in the garage. The print head is likely defective, and it does not recognize the cartridges on the left side, indicating that they are empty, even though they are full. Includes software and automatic paper roll feed. I did not connect it to the network, so I can only provide the number of pages printed: 4131 pages. Sold as is, with defects. We didn't use it much because we mostly print on our plotter. Inspection is possible. Ijdpszi Svmofx An Notk

Condition: excellent (used), Year of construction: 2007, functionality: fully functional, The water is pressed through the RO membrane by means of a high-pressure pump. The desalinated water/permeate is then led to consumption via a 1000 litre reservoir. The water containing the concentrated salts/concentrate is led to outlet. The relation between permeate/concentrate shall be adjusted manually on the needle valve. Under normal operating conditions the RO membranes have a long lifetime. But even with a good raw-water quality, layers of impurities will, to a certain extent, occur and there will be a Iedpfx Anozl E Dis Nstk slow reduction of the permeate capacity.
