35. Place powerhead assembly onto powerhead piston assembly by guiding valve rod
assembly through washer and into upper piston rod.
36. Screw piston keeper into upper piston rod.
Note: To tighten piston keeper, use appropriate wrench on piston keeper and
wrench slot on bottom of upper piston rod.
37. Align air transfer tube with air transfer tube hole in cylinder head and place cylinder
head assembly against air cylinder.
