LUBRICATION OF THE GAS TAPS
If the gas tap becomes stiff, it is
necessary to dismount it accurately
clean it with gasoline and spread a bit
of special grease resistant to high
temperatures on it.
The operations must be executed by a
qualified technician.
Normally for G30 gas, fully tighten
the adjustment screw.
