Overload
The drive can withstand brief overloads. In
the event of prolonged overload, self-
protection is activated.
This can happen in particular with high loads
(heavy grinding jars, hard samples, large
balls, high frequency).
• Check, whether the load on the
machine is too high.
• Check, whether there are any foreign
objects in the interior.
• Check, whether the rockers can be
moved easily by hand.
• Check, if the grinding process can be
run at a reduced frequency.
• Turn off the main switch and wait 30
seconds before turning the device on
again.
• If the error persists, contact the
Retsch GmbH service department.
