5. Finish tightening the five screws by using the following guidelines.
• Tighten screws 30 degrees at a time in the pattern shown in Figure 6 until you
reach 30 ft-lbs of torque with each screw.
• Do not exceed 30 ft-lbs of torque with any screw.
• Do not tighten past the minimum distance indicated in Figure 7. Tightening
past this minimum distance may damage the locking device.
While tightening the screws, the torque should suddenly lighten twice. This
indicates that both taper rings are unlocked. If the torque does not lighten, repeat
step 5, but turn each screw less than 30 degrees at a time.
