Nut that blocks the eccentric hubs of the wheels loosened

See picture 21 to check the correct disposition of the wheels

Eccentric hub turned until the wheel is in contact with the guide using a suitable wrench

NOTE: When finished, the wheel must turn easily by hand but create a certain friction on the guide

ATTENTION: it is important that there is no play between the wheel and the guide but at the same time the wheel must not be blocked

Turn off the power supply to the machine

Position and block the gun supporting-arm so as the counterweight is in line with the opening
