It is important to maintain a
correct oil volume in the
pivoting arm. Too little oil could
lead to insufficient lubrication
of the internal parts. Too much
oil will increase the temperature
of the arm. Both conditions can
lead to premature wear and an
increased need of service.
The amount of oil should be 3 dl
± 0.2 dl.
