3 Working hydraulics Corn cracker 3254
Venting
– Remove adjusting device at the corn cracker adjustment pump (230) so that the hexagon socket of piston (d) can be accessed. – Connect minimess hose to the low-pressure hydraulics measuring point (910) and to filling port (c). – Place vent hoses on vent ports (e) of both adjusting cylinders (356) on the right-hand and left-hand side. Direct the vent hoses into a collecting container. – Adjust the corn cracker adjustment pump (230) to 231 mm, see item B. Start the engine. – Vent cylinders (356 L) and (356 R) until the oil comes out without bubbles. – Stop the engine and remove the minimess hose first from the filling port (c) and then from the low-pressure hydraulics measuring point (910). – Turn in the piston (d) up to the dimension 222 mm, see figure A. – Slightly open the vent ports (e) on the right-hand and left-hand side and relieve the oil pressure, thus re-establishing the mechanical basic position. – Close the vent ports (e) again. – Turn in the piston (d) until the roller gap is 2 mm. – Check if the clearance of the cracker rollers is parallel. A tolerance of 0.3 mm is allowed. If the clearance is not parallel, repeat the venting process. – Remove vent hoses. Re-fit adjusting device to the corn cracker adjustment pump (230). In case of mechanical cracker adjustment, adjust the scale value (2 mm) on the scale. In case of electrical cracker adjustment, program the gap clearance of 2 mm in the CIS. (See Operator's Manual) Attention! During operation, the clearance of the cracker rollers must absolutely not fall below the minimum clearance of 1 mm, Material machine damage (corn cracker) may occur. – Make the adjustments correctly.
