ADJUSTING THE NOZZLE PIN OPENING ROD
When installing for the first time and after performing any maintenance work or changing the nozzle, reset lever 15) as specified below:
with the nozzle fitted, loosen the nut with extension 17);
screw in extension 17) by hand until you have eliminated all play on lever 15);
