(3) Adjust the retract rope on the boom section 2 as follows:
Use the same procedure that you used to adjust the top section retract
rope. The adjustment nut is on the side of the boom head.
• Make sure that the crane is on a hard surface.
• The boom extend rope is not adjustable.
• Do not make the adjustment nut too tight. Make sure that the
lock nut is tight after you adjust the wire-rope.

It is important to do an inspection on the swing bearing bolts. The interval of the
inspection is set to make sure that the crane operates in a safe manner.
Make sure that the bolts are tight with the specified torque.
After the break-in period, examine the bolts semi-annually or after 1000 hours.
