Standard hydraulic connections in continuous operation
NOTICE
Damage due to overheating of the hydraulic system!
When continuous operation is switched on and no attachment is connec-
ted, the hydraulic system overheats very quickly.
► Always bring the switch for continuous operation to the zero position
when continuous operation is not required.
With this function the hydraulic connections can be operated in continu-
ous operation. The scroll wheel then does not need to be operated con-
tinuously. This function is required for certain attachments that have a hy-
draulic oil motor that must be supplied with a continuous flow of oil, e.g.
sweeping brushes.
