 INSTRUCTIONS FOR CHANGING RATCHETS OR SOCKETS  
First, follow your local safety regulations strictly on this tool.
 1.
If needed, adjust the engagement of the operating rod by removing the cam casing and adjusting spacers from the gear casing.
2. While running the tool, reinstall the cam casing to the gear casing.
3. Watch the ratchet as the cam casing turns down onto the gear casing. When the ratchet starts to turn, mark its position and
continue to allow the cam casing to turn down onto the gear casing until the ratchet stops or the cam casing bottoms out.
4. Turn the cam casing back halfway between the two points and measure the amount of adjusting spacers it will take to take up the
space between the cam casing and the gear casing. NOTE:
 When changing the socket in the UOW tool, it is very important that the Allen flush head screws are tightened to 30 inch  pounds of torque and Loc-Tite with a 242 thread locker or equivalent. If this is not done, excessive damage will occur to the bevel gear 
casing and the gears.
