rubber hose adjusted to the working pressure of the gas, according to present regulation.
Use a counter tool for connecting handle (pos. 3) and hose (pos. 4) to assure a leak-proof
bond! Make sure that both parts are correctly fixed (counter clockwise). Stop valve (pos. 1)
and fine control valve (pos. 2) have to be closed (clockwise, as indicated on the valve).
