DISASSEMBLY

General Instructions

1. Do not disassemble the tool any further than
necessary to replace or repair damaged parts.
2. Whenever 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 a
subassembly unless the removal of that part is
necessary for repairs or replacement.
4. Do not disassemble the tool unless you have a
complete set of new gaskets and O–rings for
replacement.

Strainer Screen (92) in a clean, suitable, cleaning
solution. Push the prongs on the Air Strainer Screen
Support (93) into one end of the Screen and insert the
Screen, support end first, into the Body when
assembling the strainer.
