Side section locking
The operation of the side section locking must be
checked once every operating period before
commissioning the machine.
There is a spring between the plates of the lock
piece that presses the cams behind the plate in the
side section (point 1).
Lock plates should press against the side section
plates so that the cams remain behind the plate
(point 2).
Optima 500-700 :
Side section cylinder opens the locking piece automatically
before the sections start to open. The movement of the lock
piece can be adjusted with screw 3.
Optima 800-1500 :
Small cylinders open the locking pieces first and the the
oil pressure is directed to the side section cylinders.
The movement of the lock piece can be adjusted on the
length of the piston rod 3.

Front support wheel bearing clearance
Vertical axle of the support wheel has taper roller bearings. Bearing play can be adjusted by opening the
cap and tightening the crown nut. There is a same principle that with the wheel hubs. There should not
be any appreciable slack in the axle.
