3.7 Horizontal Milling
To work horizontally the milling head of the UWF

position.

• Pull the vertical head with both hands towards you
until it reaches the stop, and swing slowly
to the topside by 90°.
• Turn the releasing lever [3] to the left and, at the
same time, push the vertical head carefully back-
ward until it engages.
