1) Make sure that the tyre is clamped and deflated.
) Tip the tool-arm (17) in its working position, by lowering it until it gets hooked properly.
Always check that the arm is properly hooked to the carriage.

(fig.17)
Pay attention not to put fingers between tire and tool. In order to avoid any possible risk, turn CLOCKWISE when operating on the
outer face of the tire, and COUNTERCLOCKWISE when operating on the inner face.
6) Move the tool-holder away from the rim, release the anloock, lift the arm out of work, slide it towards the spindle and lock it in its second working
position
DO NOT keep your hands on the tool when setting it in working position so as to avoid any possible crushing between tire and
tool.

detached (fig.18)
8) Go ahead pushing the tire, it comes completely off the rim (fig.19)
