(Lay coil out in open area. Stand in middle<br />
of coil when uncoiling.)<br />
(Caution: Coil under tension!)<br />
B. Slide drive piston down riser pipe to<br />
bottom. The minimum radius of<br />
curvature of the piston rod when<br />
retrieved is 2.5 feet, which equals<br />
760 mm. Use rag during drive-rod<br />
installation to prevent damage from<br />
flange edge.<br />
