The correct belt tension is assured by the spring that keep under proper mechanical tension the support of the pulley
on the right side of the vertical frame.
Standard value: 6-7 mm
Tool: Feeler gauge
Check for a correct installation of the spring and the pulley support.
Light window between vertical frame and pulley bracket must be 6 ÷ 7 mm as showed in the figure below.
This measure assure a correct tension of the belt. So check for the correct measure by means of a feeler gauge. Set
it at 6 mm. and it must pass in the window. Then set the gauge at 7 mm. and it must not pass in the window.
Adjust if it is necessary fixing properly the pulley bracket in order to have correct measure of the window.
This gives a tension value of the carriage belt of 7 Kg ± 0,5Kg.
