Disassembly

Refer to the Illustrations and Parts Lists.
Complete disassembly of the tool is not recommended.

The disassembly procedure is divided into sections of
the tool. Disassemble only the section(s) necessary to
complete the repair.
Note: Remove blade before attempting to disassemble
any components of tool. Refer to "Blade Removal/

Disassemble the tool on a flat, clean surface. Take care
not to lose or damage any parts that may fall free during

parts in tool that are not removed for signs of damage,
wear, cracks, etc. Replace any parts which appear to be
