NOTE: Do not exceed the recommended amount of air pressure or it may damage or cause seals to roll.

Apply 138 kPa (20 psi) to the feed holes marked 2 and 4, and listen for the second and fourth clutches to apply.
Hold the pressure for five seconds. If the clutches do not apply and hold, then disassemble the driven sprocket support components. Inspect all of the seals and clutches for proper assembly. When finished, repeat the functional check.
