Sorry it took so long to get back we had a few delays with the unit.
For the electric motor slides, the manual basically said put you manual crank on the motor and start turning. You can see the hex shaped shaft in the photo below. The cotter pin helps hold the factory supplied crank on the shaft.
For the hydraulic slides you have to put a drill on the end of the motor. It does not state where but based on other similar hyd. power units I have seen the will be a plug or decal at the end of the electric motor and the shaft end will be behind it.
