DISASSEMBLY
1. Remove valves at parallel pins.
IDo not use a magnetic hand.
a. Use a wire paper clip to push out parallel pins.
b. Remove parallel pins while pressing their corresponding plugs and sleeves.
I Remove plug slowly to prevent internal parts from jumping
out.
c. Place mating surface of valve facedown, and remove internal parts.
I If a valve is hard to remove, place valve body facedown
and lightly tap it with a soft hammer.
I Be careful not to drop or damage valves and sleeves.
2. Remove valves at retainer plates.
a. Pry out retainer plate with wire paper clip.
