Unpin the rod end of the lift cylinders and use another loader to raise the boom until you can engage the boom locks. You can also install a hose into the bottom outside port of the lift cylinder, remove the line at the top of the lift cylinder and use another source of hyd flow such as skid loader, tractor, pump. You will need to put a bucket under the removed line and also the top port of the cylinder because as you raise the loader oil will flow out of each.i imagine there is a valve that has to be bypassed or opened but i cant find it to save my life. any information would be greatly appreciated.
