DANGER: DO NOT CLIMB ON SIDES OF BALER. USE A LADDER OR WORK PLATFORM
WHEN WORKING ON TOP OF THE BALER OR OTHER AREAS OF THE BALER THAT CAN
NOT BE REACHED FROM GROUND LEVEL.
Using the “MANUAL DOWN” button, run
the platen to the fully down position.
Lock-out and Tag-out the power per the
instructions on page 2-1.
Relieve any stored hydraulic pressure by
pressing in on the solenoid valve pins
located on each end of the directional
control valve. Use a small blade
screwdriver or small allen wrench to
perform this operation.
Remove the 1/4” plugs in the “A” and “B”
