:
If the pendulum packer hits hard at the end of its upper or lower stroke, you can adjust the
cushioning speed by which the packer ends its stroke by using this choke valve (see Figure
3-69). Turn the valve clockwise or counter-clockwise to reach the proper adjustment. Several
attempts and testing may be required.
