Install the carriage legs and adjust the legs so the tool is approximately centered to pipe.
Place the tool inside the pipe and, if needed, make minor final adjustment to center the tool
in the pipe. In some cases the legs may need to be shortened, or replaced with longer or
shorter pipe.
Attach an ½ ″ I.D. air line to the air motor quick coupling.
Connect a pipe lance or blast hose to the PBT-2 Blast tool.
ATTENTION!
Hose disconnection while under pressure could cause serious injury
or death. Use safety lock-pins and safety cables on all coupling
connections to help prevent hose couplings from accidental
disconnection.
