This is standard on almost all of the smaller machine tools from the far east.
The way they keep the price down is to only assemble at the factory, not to set them up for use.
Some retailers do offer a set up service, but it is rather expensive, say 200 to 300 squid.
If you spend a full day or two going over the machine with a fine tooth comb, cleaning, tweaking and lubricating as you go, not only will you get a well running machine, you will learn all about it at the same time. Leaving things until they show their ugly head is one of the main reasons people give certain machines bad press. After they have spent wads of cash replacing loads of broken tooling, all caused by their eagerness to make something straight away.
I am sure that this is the reason a lot of newbies, who go it alone, end up selling their equipment off. They just find that machining isn't as straight forwards as they expected.
I am asked to occasionally look at used far eastern machines that people want to buy. Usually hardly ever been used, and no attempt has been made to set them up correctly.
