Install Crank Handle (Manual Version) - Siemens Milltronics MWL Weight Lifter Operating Instructions Manual

Check clearance for conveyor belt
1. Ensure there is 10 mm (0.38") minimum clearance from the top of the torque tube to the
underside of the return belt: inadequate clearance will cause the belt to wear.
2. Allow additional clearance for belt sag.
3. If necessary, shim the idlers in the scale area until the clearance is adequate. (See the belt
scale operating instructions for detailed shim procedures.)

Install crank handle (manual version)

Note
The crank handle is only required for the manual version of the MWL. The electronic version
comes with an AC gearmotor already installed in place of the handle. The motorized crank
bodies allow for mounting of the electronic components on the left or right side. IF the MWL
has been ordered incorrectly, these parts will need to be removed from one side and
installed on the other. For mounting the proximity switches, a gap of 0.635 to 1.016 mm
(0.025" to 0.04") must be maintained.
1. Determine whether it will be more convenient to have the handle attached to the left-handed
or the right-handed crank body, and if the shaft extension is required.
2. Remove the plastic cap from the input shaft on the selected side.
3. If the shaft extension is required, slide the female end of the extension over the exposed
input shaft, and secure the extension with a bolt, nut, and washer.
