6.
With hand force still applied, tighten each screw until it slightly compresses spring
washer (Figure 8-50). After all four spring washers are pinched, release meshing force.
NOTE:
At this point, the screws should be tight enough that the motor would not free-fall
under its own weight when turned 90 degrees. When the piston/cylinder is upright,
however, a firm force applied by two fingers should be enough to move the motor to
the end of its screw location slots.
