6. Install the poppet valve into the pilot valve and torque to 73 ft. lbs. (100 Nm).
Adjusting the Speed Valve
Note: Do not adjust the speed valve while the cylinder is
moving.
1. Fully close the shear jaws.
2. Turn the pilot valve adjustment screw all the way counter
clockwise.
Note: Do not turn the pilot valve adjustment screw past the
locking nut. This will cause damage to the pilot valve.
3. Make small adjustments to the pilot valve adjustment
screw until the jaws just fail to shift into high speed. This
is the minimum setting.
4. Return the shear to the fully open position.
5. From the minimum setting, adjust the pilot valve
adjustment screw clockwise half the number of turns
required to reach the minimum setting.
