ATTENTION
When operating on gas, the machine emits combustion fumes directly into the surroundings where it is being used;
therefore, gas-powered machines must not be installed in rooms with a volume of less than 12 m
3
, as described by the
standards in use;
In closed rooms, always provide ventilation openings to release any possible gas leaks.
