A gun that does not have a trigger is dangerous to the operator and to the home being worked on. A gun that is dropped and where there isn’t a trigger release to shut off the flow of steam can injure the operator and can come in contact with the home causing damage to paint, siding, etc. Also, when an operator is removing ice, he needs his hands to remove ice and to reposition the tool to efficiently melt the ice. Without a trigger, the steam continues to stream which results in more excess water being used. A trigger on steam machine is a vital safety component.
