18. MOUNTING AND DEMOUNTING THE WHEEL GUARD
To assemble and disassemble the wheel guard, refer to the user and maintenance manual.
If there the guard works incorrectly (e.g. when the guard is lowered, the machine does not spin, or vice versa), check:
- the connection of the micro-switch cable and, if necessary, the connection to the MBUGRF board (G, fig.3).
- that the micro-switch is working correctly (13, Fig.3a). If the micro-switch is NOT working correctly, replace with a new component.
Proceed as follows to replace the micro-switch:
- remove the weight tray;
- disconnect the AMP connector from the Mother board
- remove the micro-switch by removing the two fastener screws;
- replace the micro-switch, following the procedure for removal in reverse order to fit the new component.
Should it be necessary to replace the gas strut, proceed as follows:
- remove the weight carrier tray;
- loosen the nut A in figure 18;
- remove nut B in figure 18;
- undo the screw (C, Fig.18) to extend the gas strut completely;
- fit the new gas strut, following the procedure for removal in reverse order. Tighten the nut (C, Fig. 18) fully to set the gas strut extension correctly.
