take attachment off if it has one,remove auxzillary hoses and guard at top of lift cyl. remove brass stopper. it has an allen bolt holding it in. 10mm allen wrench, raise up carriage about 3/4 and use a good quality chain to hold it up.lower lift till lift chain is loose.remove allen bolt that bolts into back of carriage just below liftchain anchor. I hook a bungie cord onto chain so it does not roll back. carriage can be lifted up out of mast. Now when lifting carriage up brass stopper can be taken out and it is easy to unscrew allen bolt when it is above lift cyl
