STOWED DEDUCTS
When attachments such as flys are stowed, it is necessary to make a reduction in the rated capacity of the
crane. This reduction, also called a deduct, is specified in the capacity chart. The MG424 has the ability to
store this data and to make the deduct from the chart.
This reduction is applied by use of the DEDUCT controls as follows.
Start the selection by pressing the STOWED push button. The display will change to show the current
selection in the center display. Use the UP or DOWN arrow to scroll through the selection menu. When at the
required Deduct, press the SELECT push button to complete the selection of the new Deduct and return to
the normal working screen. In order to remind the operator that a DEDUCT is applied, a lamp is illuminated in
the deduct information panel, which is below the Stowed push button. To view the current selection, when
indicated by the illuminated lamp, press the Stowed push button. After confirming or changing the selection,
press the SELECT push button to complete the selection and return to the normal working screen.
