Checking the nozzle for Tightness:
Operate hand lever until the gauge reads 35 bars ( 35 kp/cm2) less than the specified pressure.
The nozzle is tight, if there is no afterdribble within 10 seconds.
Buzzing and Atomizing Tests
Operate hand lever quickly (one or two downstrokes per second) and check that the nozzle emits a
buzzing sound.
Jet Test
Keep your hands from the fuel jet!
Keep a sheet of blotting paper in front of the nozzle and check that all nozzle orifices are free so as to
