This model has a belt drive system which can help reduce turntable noise. The downside of belt drive systems is that the belt has to be set at the right tension and should the tension be wrong it will affect the speed. A slack belt will turn too slowly and a tight one too fast. I haven’t seen this model but on most decent turntables there is a tension adjustment system which ,combined with a strobe light, can be used to tune the speed of the table.  Another problem can be caused by an incorrect power source. It is important to know that 110 volts AC  are usually provided at a frequency of 60Hz and 240 volts AC are usually 50Hz so if you have a model that was built for a 110VAC market such as the USA connecting it to a step down transformer in Europe with 240VAC does not change the frequency of the electricity and the motor on the turntable may run at the wrong speed or even burn out
