7.Remove platen from front of baler.

8.Turn on power and retract cylinder rods.

9.Disconnect and Lock-out and Tag-out power per instructions on page 2-1.

10.Relieve hydraulic pressure by manually depressing solenoid valve (both sides).

11.Relieve pressure on the counter balance valve. Loosen the locknut on the counterbalance valve and adjust the valve clockwise all the way in to relieve the pressure.

12.Disconnect one hydraulic hose at a time. Plug the hose port before disconnecting another hose. NOTE: Remove hose fittings slowly.

16.To reinstall the cylinders, reverse the above steps.

NOTE:Use new bolts, nuts, and cotter pins when re-installing the cylinder pins.

17.After reinstallation of cylinder(s), readjust pressure on the counter balance valve. See Page 2-4 for proper procedures.

1.Remove hydraulic cylinder from baler.

2.Remove retainer nut from gland.

3.Remove internal retaining ring.

4.Remove rod from cylinder barrel.

5.Remove piston locknut and piston from cylinder rod.

6.Replace all seals. Discard old seals and old piston locknut.

7.Replace gland on rod.
