RA27 SERVICE
BACK END / ADVANCE LEVER
This next section covers service on the backend of the RA27. Should the tool
experience problems with load advancement, or problems within the firing mechanism,
the following steps will guide you through replacing the various components and
thoroughly cleaning the backend assembly. Before beginning, make sure the tool is
unloaded. It is also recommended to remove the front-end components. Follow the
previous section for further information on how to do this.
1. Begin by removing the rubber
Backend Cover from the rear of
the tool. The cover is held in
place by a rubber tab feature
fitting into a recess in the rear
hook assembly plate. Locate an
edge of the cover and pry it off by
hand.
2. Under the Backend Cover there
are three screws, one holding the
belt hook and the other two at
12:00 and 6:00 are to be
removed to gain access to the
back components. Use a 5/32”
or 4mm hex key wrench to
remove these screws.
NOTE: There is spring force
under this plate. Use caution
when removing these screws.
It is not necessary to remove the
screw holding the belt hook in
place. The back cap can be
removed with this screw in place.
