Hi Al, i understand that

I have never seen any documentation from the manufacturer or anyone else for that matter suggesting that this guarantee is under the condition that there is a minimum load applied to the cylinders. A mechanical failure of the cylinder, operated as intended and within the specified psi, unmodified and undamaged/not worn, would be a product or design failure by the manufacturer. These cylinders are designed to be operated under the specified pressure and are not subject to the condition of a minimum load to be safe. Yes they will actuate very fast (especially smaller diameter cylinders) but especially when restricted to 60psi (again less than 50% working pressure) we are well within the scope of intended and safe use specified by the manufacturer.
