Graco MP-25 Operation page 39

Important Safety Instructions:
Keep hands clear when swinging the motor into place.
Swing the motor assembly into position, checking that the shaft assembles into the slot in
the auger drive, and that the location dowels on the motor assembly locate into the pilot
holes in the hopper assembly. It may be necessary to swing with some momentum to
enable full closure, if either the motor or the pump has recently moved position.
Note: the drive shaft will likely become tight between the two drive slots during static
assembly. Once the unit has been running, the compressive force will be reduced or
eliminated to within working limits. During pumping the compression will be present,
during reverse the compression will be relieved.
If full closure cannot be achieved with reasonable force, then replace the safety grid with
all fasteners in place and the clamp held shut as far as possible, then briefly "jog" the
motor using the stop start switch and the water pressure bypass fitted, and the motor
assembly will close to fully shut.
Important Safety Instructions:
Replace the safety grid back onto the top of the hopper and secure using the 4 clips, bolts
and washers. Operation of this machinery without the grid in place is prohibited. Ensure
the grid is in place when clearing or operating the machine.
