10.12 Tension arm lock
The tension arm lock is provided so that the hydraulic and spring pressure can be
released from the belts when clearing a blockage within the machine or carrying out
specific maintenance operations. (See the following decal CST00689)
Operate the tension arm lock, using the following procedure.
1.
Move the lock lever ‘
B
’ from the normal working position to the maintenance
position, this will cause the stop to move into the bale chamber.
2.
Next the chamber door of the machine should be opened fully so that the
tension arm passes the stop.
3.
In order to release the pressure from the belts the tailgate must now be closed
approximately half way so that the tension arm rests on the stop inside the bale
chamber, allowing the belts to hang loose.
4.
Close the chamber door lock immediately.
5.
Release hydraulic pressure.
Release the hydraulic pressure from the tension arm by pressing the density release
(button L5) on the control box until the pressure on the clock falls to zero before
carrying out any work inside the chamber or under the tailgate.
CAUTION: Close the chamber door lock first
Ensure the tailgate safety lock is engaged before carrying out any work
inside the chamber or under the tailgate.
