Do you have a new one to look at? A vertical rod extends down form the vacuum canister. At the far end of the rod is a pin that when installed is parallel with the road wheels. The pin sticks out towards the port side. IIRC it helps to push down the STOP lever then tilt the actuator so the canister is further port and the pin is further starboard then lift off the actuator.
