8.1.1 Preparing for butt fusion
Heating element butt fusion joints may only be done by carefully trained
personnel.
Place pipe/pipe, fitting/fitting or pipe/fitting in the clamping device. The
pipes/fittings must be correctly aligned in the axial directlon.
Swing in planer and hold with left hand.
It is important that the safety hook is fastened on the guide shaft.
Plane by pushing together until both surfaces to be joined show no
unmachined areas. The contact pressure should not exceed 25 kg.
If only one side needs to be planed (e.g. beveled pipe), the aluminum stop on
the underside of the planer can be removed for the corresponding side.
Before fusion, both sides must always be planed (at the same operation).
