Adjusting the Nautilus HD lift arms
CMK 11-4-2015
This sheet indicates how to correctly adjust the Nautilus HD hopper and hopper lift arm cylinders
When installing the upper clevises onto the bumper and hopper lift cylinders it is important, in order not
to cause the clevis to contact and cut into the lift arms, to screw the clevis onto the threaded rod of the
cylinder until the end of the cylinder rod sticks out 1/8 inch beyond the top of the clevis base. This initial
setting will be finally adjusted after the lift arms are operational.
When the machine is operational:
With the bumper and hopper lift arms fully raised:
1. Adjust the hopper lift cylinder upper clevis so that the hopper dump door, when open, is 61-1/2
inches above the floor.
2. Adjust the bumper lift cylinder upper clevis so that the bumper lift arm stops just before it
contacts the hopper lift arms.
3. Tighten the clevis locking bolts.
