7._Rim clamping
Tip the tool-arm (17, fig. 11) in its non working position. By means of the lever (3) move the ramp (10) away from the spindle and place the tire as
-
sembly in vertical position over the sliding ramp.
While clamping, make sure that the rim is well positionned on the flange plate, so as to prevent the tire from rolling down.
By means of the lever (4) lift or lower the spindle arm until the flange plate is best centered to the rim.
To facilitate this operation, it is advisable to keep the anti-rotation flange pin (20) in the lower part of the rim.
Let the anti-rotation pin (20) match with one of the lug holes of the rim as indicated in fig.15 Place a clamping cone with suitable size in teh rim center
hole. Set the locking hub nut (8) on the shaft and lock everything by turning the hub nut as far as it goes.
The machine has been designed to work on 14”-26” tyres mounted on rims having central hole of min. 4” (100 mm.) – max. 12” (300 mm.) diameter.
According to the kind of rim, it is therefore, necessary to act in different ways to lock it onto the flange.
RIMS WITH CENTRAL HOLE Ø ”- 8” (100 ÷ 00 mm)
To clamp these rims, use fixed flange plate (A fig. 13) together with small cone (B Fig.12)
RIMS WITH CENTRAL HOLE Ø 8” - 1” (00 ÷ 00 mm)
To clamp these rims, mount big flange plate (C, fig. 13) and use big cone (D Fig. 14)

DANGER! POTENTIALLY HAZARDOUS OPERATION!
Do it manually only if you are certain you can keep the tire assembly balanced. For large and heavy tyres
an adequate lifting device must be used.
