NOTE: The stop on the driver’s side is located
immediately below the cylinder rod end
and is threaded into the cylinder mount
arm. The stop on the left side is located
directly above the arm rotation plate.
4. After the 3½” (8.89 cm) clearance is
established, make sure both stops make
contact simultaneously. The lower front
edge of the hopper should be 5” (12.7 cm)
to 6” (15.24 cm) from the floor. A balanced
adjustment of both sets of adjustment bolts is
required to correctly adjust the hopper in the
lower position. If the bumper is lower than the
frame, after the hopper is correctly adjusted,
loosen the bumper attachment bolts and
reposition the front bumper.
5. Raise the hopper and rotate fully.
6. Turn the engine off.
WARNING
Do not rely upon the hydraulic cylinders to keep
the hopper raised for maintenance. Always
engage the safety arm before servicing the
hopper.
7. Adjust the rotation cylinder stops on the
hopper rotation arms on each side of the
hopper so that clearance between the lift
arms and the cut-outs in the bumper is ¼”
(6.35 mm) maximum.
8. Loosen the locking set screw in the bottom
side of the rotation block.
9. Using the hole in the cylinder rod, turn the
rod to adjust the cylinder extended length to
match the hopper rotation stops.
10. Tighten the set screw.
11. Rotate the hopper back, remove the safety
arm and lower the hopper.
