Please assist. Our ATF80-4 has popped a oil seal on the boom gripper. On the part that operates the ext/ret of the boom pins. My last boom section is still in the stowed position so now I can't get to the gripper via the top inspection hole. Any ideas on how i can move the last section just about a metre so that I can get to the gripper. I can lock onto the section BUT I can't retract the section's boom pins. I can see them from the outside though. Any assistance will be appreciated.
