Depending on the selected speed, the V-belt will have to be lifted directly onto the motor pul-
ley oronto the pulley of the primary transmission. Two V-belts of different lengths have there-
fore been provided for the TU2506 lathe.
Handle the V-belt with care. It must not be damaged or overstretched.
Retighten the tension pulley and fasten the nut again.
The correct tension of the V-belt is achieved, when the V-belt with the fingers may be de-
pressed about 3mm.
ATTENTION!
Make sure that the tension pulley has contact always only on the outside of the V-belt.
Make sure the tension of the V-belt is correct. Excessive or insufficient tension may
cause damage.
