be screwed into the manifold
using a hydraulic loctite thread
sealer and tightened down.
Slide the handle over the
hydraulic quick disconnects and
up the hoses to the manifold.
Then insert the lemo wire
through the strain relief which is
attached to the alum. Base
plate and feed the wires up
through the handle and attach
the alum. Base plate using two
#10-24x1/2” long BHCS.
CV plugs (CVES2503231A Dia.
.250” short) are put into the
manifold first using a hammer
and the installation tool
Then a 1/16x5/16 socket
pressure plug (3/4 taper) with
blue loctite is screwed into the
manifold.

The wires, RED and GREEN go
through the handle and manifold for
the micro switch.
Place the handle up onto the
manifold and put the #10-32x3/8”
BHCS into the handle which will
attach the manifold to the handle.
Slide the other half of the alum.
Base plate onto the hydraulic hose
and push into place for the other
two #10-24X3/3” BHCS.
Then the BLACK and WHITE wires
go out through the trigger housing
until the trigger is connected. At this
point you can push the trigger into the
trigger housing hole in the handle.

With the handle attached to the
manifold put a small amount of
lubriplate grease around the holes
in the top of the manifold where
the barrel connectors go.
Then put some lubriplate grease
on the assembled barrel
connectors ( o-rings and back-
up rings) and push carefully into
the holes in the manifold.
Install the second barrel
connector using the same
process as the first.
