Requires manual dexterity and a transition to the hardware store

In order to the bicycle trailer to have joy one must remember 2 things: The screws and the two axes are incredible botch and the manual assembly is incomplete, misleading and illegible.
(Note: Unpacking where Gebrösel by sandblasting is not a problem - not on the Persians in the living room.)

Anyway, you can use that thing when you go before the assembly to the hardware store and there, all the screws and nuts exchanged for some who have reasonable thread (preferably equal to stainless: brass or stainless steel, the nuts "self-locking"). These anxious you feel the same, a 100 Pack washers or Karrosseriescheiben to up to 5 mm clearance to compensate.
The axis I and a matching in the pipe M8 he replaced with 12mm outside diameter steel pipe threaded rod. The one must be 2 times saw off to the correct length and you need 6 per axle nuts (outer nuts counter). Make sure that you do not throw away the windows of the original axle set, at least with the small cones should be used further. (The original axes have a M10 thread, but with less than 9mm diameter !!! The included nuts have no better manufacturing tolerance so that they have at handsfree attempt to attract them to slip through without significant effort.)
Screws, nuts, washers, threaded rod and steel pipe have cost me about 8 euros.

By the way smells not only the plastic tub pathetic, the tires need some days of sun and wind - the trailer should not at least 1 month in closed spaces, and certainly not in inhabited.

Conclusion: The product should be understood as a 3D puzzle for girls and boys from 12 years, which after assembly has a practical value. The 1-sheet A4 copy-building instructions should be to use on the back to send an angry letter to the vendor.
