DISASSEMBLY
General Instructions
1. Do not disassemble the tool any further than neces-
sary 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 pro-
tect the surface of the part and help prevent distor-
tion. 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 neces-
sary for repairs or replacement.
