Good afternoon.
I need help with an issue. Where the boom section number 4 on the Kato NK 500 E III crane cannot be retracted perfectly. Thank you for your assistance. I truly appreciate it.

Will it retract completely if you hold the control in retract? Will it stay there in that scenario?

Just a couple of thoughts. Looks like it’s both 3 and 4 that won’t retract fully by looks of the picture. Have you inspected the boom for loose wear pads laying in the bottom. Or possibly checked the extend/ retract chains or cables for correct adjustment??
