KUBs and OCs Exit doors leaking gas

Ngweitong SG

If some of your notice,there is an increasing number of KUBs and OCs leaking smelly gas when doors closing, esp the euro IV KUBS…

For those who donno, eg SBS8133Z when doors open and close, the gas, that is used to operate the doors, leaks and travels through the aircon ducts, and smell of the gas is unbearable, poisonous like…

One example of OCs is SMB103Y

could be the maintenance team pumped in more air on KUBs to make the door more power to open/close.
