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

FEED GATE IS RAISED.
HYDRAULIC SYSTEM PRESSURE SETTING-(continued)
Continue to press the “MANUAL DOWN” button and adjust the Relief Valve to
1800 psi.
While holding 1800 psi. adjust the pressure switch until Relay 3 (R3) energizes.
Continuing to press the MANUAL DOWN button, adjust the relief valve to 2000 psi.
Tighten the lock nut on the Relief Valve.
Lock-out and Tag-out power per the instructions on page 2-1.
Relieve any stored hydraulic pressure by pressing in on the solenoid valve pins as
described in Step 3.
Remove the pressure gauges from the “A” and “B” ports and reinstall the 1/4” plugs.
Remove the Lock-out and Tag-out and turn the power “ON”. The pressure settings

This baler is equipped with a solid state output magnetic interlock switch. Because
it is a semiconductor device, it can not be checked with a continuity light or OHM
tester. The switch must be checked with the power ON. The RED WARNING
LIGHT on the control panel has been provided to indicate if the switch is working
properly.
To check the switch, turn the keyswitch to the ON position. When the feed gate or
bale door is open, the light should be off. When the bale door and feed gate are
closed, the light should be on.
If further verification is required, a voltmeter (120V) may be connected to terminal
#2A and terminal #7 in the panel box. The meter should read “0” volts with the gate
open and 120 volts with the gate closed.
In no instance should the baler operate in either MANUAL DOWN or AUTOCYCLE
with the feed gate up or bale door open. 1.
