DISASSEMBLY

General Instructions

1. Do not disassemble the tool any further than necessary
to replace or repair damaged parts.
2. When grasping a tool or part in a vise, always use
leather–covered or copper–covered vise jaws to protect
the surface of the part and help prevent distortion. This
is particularly true of threaded members and housings.
3. Do not remove any part which is a press fit in or on an
assembly unless the removal of that part is necessary for
repairs or replacement.
