1. Attach the vacuum extension plate assembly (C) to the fixed vacuum cup (D) on the B4A aimer. This is best
accomplished with the fixed cup (D) fully extended (Fig. 9).
Squeegee the fixed cup (D) into the round hole in the back of the vacuum extension plate (Fig. 10).
2. After the vacuum cup extension plate (C) has been installed onto the fixed B4A vacuum cup (D), the
articulating vacuum cup (A) can be attached to the vacuum cup extension plate (C). If used, the threaded
extension studs must be seated firmly against the "O" ring in the vacuum cup extension plate (Fig. 11).
The two extension studs (B) can be placed between the vacuum cup extension plate (C) and the articulating
vacuum cup assembly (A) for maximum extension when needed.
