Difficult Start

[Larry]

The RN46 piston will not retract to the firing position. After pushing it in several times, it might start to operate and will then operate OK. However, if the air hose is removed, and pressure is lost, it is difficult to start it again.

I suspect gummed up lubricant. Would dismantling and cleaning with naptha solve my problem? Or is it a defective part?

Do not use naphtha. Replace rubber with RN46-RK
