I purchased an HP-CS by Iwata recently and just got the compressor in so have been playing around with it. I notice with the air action on the trigger there is a dead space of about half of the action. I can put my finger under the hat of the trigger and pop it up another couple of millimeters or so but that space essentially doesn’t do anything when trying to control the air flow. This means the I have almost no trigger action to control how much air I get from the brush itself. Is this normal? I have watched a lot of video but can’t really tell how much play is in the triggers. Thanks for your time! Quick follow up as I think about it, I have heard the iwata cleaner isn’t ideal, is this true? Something about it gunking up in the brush.
