11. Place a wrench on the middle size hex (3, Figure 4-36 or Figure 4-37) and a
second wrench on the large hex (4) to prevent cartridge rotation, rotate the
middle size hex three revolutions counter-clockwise (CCW) to open the bypass
valve. Do not rotate more than three revolutions, as additional rotation will
generate external leakage.

13. Move the propulsion control to the full forward or reverse position.
14. Remove the chocks and tow the machine.
