Test for Slippage
Bring the fitting against the main under initial heat (bead-up)
pressure to insure that no slippage or movement of the main or
fitting occurs.
IMPORTANT: A piece of slightly larger pipe could be used as
a spacer between the saddle base and the movable jaw to
prevent slippage.

Clamp Fitting
Position the fitting, and bolster if required, loosely in the movable
jaw. Close the carriage to properly position the fitting on the
main. Tighten the clamp knob.
Be sure to allow enough travel for the melt pattern and fusion to
occur (3/4" min.).

Set Hydraulic Pressure
Check hydraulic pressure. Shift the selector valve to the center
position to set the pressure for heat/soak. With the selector valve
in the down position, the initial heat (bead-up) pressure can be
set. With the selector valve in the top position, the fusion pressure
can be set.
Consult the pipe manufacturer's recommendations or appropriate
joining standard for proper pressures.

Clean Surfaces
Use 50 or 60 grit utility cloth or scraping tool
to clean and rough the main to expose fresh
material.
Rough the base of the fitting unless the
manufacturer specifies otherwise.
