The following disassembly and assembly procedures
apply to all models except where noted.
Disassembly:
1. Secure the tool in a vise by the right handle (handle

through the access hole in the end of the handle grip,
hook the spring, pull the spring slightly towards you,
twist 90 degrees and unhook the spring (P8678FS)
from the pin. Note: removal of the handle grip is no
