Assembled jaws are retained in their respective Carriers by a pair of ball-detent devices. Jaws are removed one at a
time by pushing with fingers or thumbs (as indicated by the red arrows in Figure 12) to release the detent mecha-
nism. Each jaw will rotate toward the other and then can be lifted out of the tool. They are installed by reversing the
removal operations. Do not use force or tools to install or remove them. Doing so could damage the BarbLock®
Assembly Tool. If the jaws do not install easily, then it is very likely they are not in the correct position or orientation.

WARNING – Pinch Hazard:
be aware that if the lower jaw carrier has been manually pushed away from its fully
open position while the air supply is disconnected, it will immediately return to the fully open position as soon as
air pressure is re-applied to the tool. This will happen no matter if the Safety Cover is closed or not! Be aware of the
possibility that the lower jaw/carrier may move while connecting the tool to the pressurized air supply. Keep fingers
and hands away from the area of the jaws and carriers while the air supply is being connected.
Operation of the BarbLock® Assembly Tool: The tool is designed to be used by a single operator. To begin the
BarbLock® assembly sequence, the operator will pre-assemble the BarbLock® components onto the tubing. Refer
to the diagram below for general information. Isopropyl alcohol is allowable as a lubricating agent for the pre-as-
sembly operation only. The pre-assembly is then installed into the jaws of the Assembly Tool. Do not apply any
fluid to the BarbLock® components after they have been loaded into the tool. The fluid could contaminate sensitive
components and shorten life of the Assembly Tool. This manual is provided as a guide for operation of the Bar-
bLock® Assembly Tool. Contact Saint-Gobain Performance Plastics if additional information regarding pre-assembly
of BarbLock® components is needed. Figure 16 below illustrates a pre-assembled BarbLock® loaded into the jaws
of the Tool. Note that the flange of the barbed fitting is above the “rim” of the upper jaw. The Safety Cover is then
closed and latched.
