hello im new to this sight and to excavators. i have a 98 model tb016 and when you swing and let go of lever it dosnt stop straight away it will rock back back and forward. even when the machine isn't running i can rock it back and foward by hand it moves about 10cm (4inch). it has no up and down movement in the swing bearing. what could this be and is it a easy fix. also where could i get a pdf workshop manual for it?
