At lowering the flat-jack, I turned the valve cap completely off the valve instead of partly. Now my flat-jack cannot be stored completely flat anymore. Is this a guarantee case?

Answer: when the valve cap is completely turned loose from the valve, it may happen that the flat-jack, under the force of the recreational vehicle, is lowered too fast. This means that all the air in the flat-jack is forced out of the little valve with extreme pressure. This may result in an extra alternative pressure on the inner partitions of the flat-jack. These partitions can then rest partly upright instead of move completely down when the flat-jack is lowered. Your flat-jack keeps on functioning without a problem and inflating is just like always, but storing your flat-jack completely flat is not possible. The motto is: Just follow the instructions for use and let the flat-jack lower gradually. Do not take the valve cap completely off the flat-jack at lowering procedure, but only unscrew the valve cap partially to let the air flow out of the flat-jack gradually. Just like you do when you lower [...]

Answer: yes, that is possible. There are two kinds of flat-jacks for campers and caravans. The one we sell is the flat-jack Camper Plus which reaches 12 cms of height. The other one is the smaller flat-jack Camper, which reaches only 6 cms of height. This flat-jack Camper version can be stacked, but maximum to be stacked is 2 pieces, which leads to the same 12 cms height as 1 flat-jack Camper Plus. The price of 2 flat-jacks Camper is almost double the price of 1 flat-jack Caper Plus. That is why we only offer the flat-jack Camper Plus, being more efficient.

You can only order your flat-jacks directly at us through our webshop at or or   Alternative is purchasing the flat-jacks in our fair stand, where we do demonstrations for the public as flat-jack importer, by using our classic orange Mercedes-buscamper.

This might happen if you buy the flat-jack at other companies than ours, as official importer. In that case you cannot claim guarantee at our place, but only at the company where you bought your flat-jack. Most foreign dealers or parallel/grey importing dealers do not give guarantee, and do not know the flat-jack product in detail like us. They only sell, and are mostly not there to help you afterwards in a guarantee case. Also they often deliver the 6 cm high flat-jacks instead of the better 12 cm ones that we deliver, and they do not tell you or even say they do the 12 cm versions but deliver the 6 cm ones. So beware and never buy there!

Out advice: just buy your flat-jack directly at us as official importer, then you are sure of the official works 2 year flat-jack guarantee and serious support!

Answer: for flat-jacks that you bought elsewhere (for example in another country or through parallel or grey import) and not directly at us as importer, you cannot claim guarantee at us. But you can try to claim your guarantee at the company you bought them.

If that other company does not help you, then we can do you an appropriate offer for another flat-jack to replace your old flat-jack. In this case inform us in detail through our contact form, and do not forget to enclose an invoice of the company that delivered the flat-jack to you.

Damage as a result from not following the instructions for use means there is no guarantee case. Cleaning the ground under the flat-jack is clearly stated in the instructions for use.

We regret that you experienced this. That is why we can do you an appropriate offer for a new flat-jack, if you send us your invoice you got from us. You can ask for this offer through our contact form.

Answer: Always take care that your camper/caravan/folding caravan is exactly in the middle of your flat-jack. Both in length and in width in the middle. If this is not the case, the load of your vehicle (thousands of kgs) is all focused on one side and can make the weld seam break. This is not a guarantee case, because the instructions for use are clear: put your vehicle exactly in the middle of the flat-jack, so each weld seam (front and back side, right and left side) of your flat-jack is burdened equally by the load. If you have an exploded weld seam, this indicates you either pumped the flat-jack with pressure over the maximum of 1.2 bar or you were not centered in the middle on the flat-jack, so one weld seam was more burdened than the other.

We regret that this has happened to you. That is why we, as flat-jack importer, will [...]

Answer: The instructions for use will be sent to you together with your invoice when you order your flat-jack through our webshop. If you do not have this e-mail with invoice and instructions for use anymore, you can send us a request through the contact form on the flat-jack website to receive again the instructions for use of the flat-jack.
