B. Regulator Kit
First follow “Handle Disassembly Instructions,”
Procedure A on page 13. Then remove the two large
Phillips head screws to the rear of the wire terminals on
the right hand side of the handle. This allows the
regulator assembly to swing free, connected only by
the hose going from the brass rear of the regulator to
the loading chamber assembly, and then main hose
assembly. Remove the main hose by unscrewing the
elbow fitting from the regulator. Use a 5/16’’ wrench
to remove the loading chamber hose from the regulator.
Reassemble with a new regulator using reverse
procedure. Be sure hose fittings are quite snug. Check
for air leaks by activating the regulator. Once this is
done, reassemble the handle and heat shield.
