Do not operate Reactor without all covers and shrouds in place. Do not attempt to change ratio while machine is pressurized or running. Do not loosen ratio lock handle if A and B component pumps are pressurized or while the pumps are operating.
1.Select ratio
The stroke lengths of the fluid pumps (AA and AB) can be adjusted to select the ratio. The frame (AN) has three pin positions for the bottom of the pump and a slider mechanism at the top of the pump, which allows for positioning of the pump at any required position. This allows for a a range of ratio settings between the first and last settings on the pump drive link.
