Butt Fusion Procedure
Check Alignment of Pipe
Bring the pipe ends together and check for alignment. If high/low
(misalignment) exists, adjust by tightening the high side clamp. When pipe
is properly aligned, tighten both clamps simultaneously to ensure against
pipe slippage.
NOTICE: When clamping, do not over-tighten the clamp knobs because
machine damage can result. Check to see if there is space between the
upper and lower jaws. If the two jaws are touching, do not continue to
tighten.

Positioning Pipe in Machine
Position the facer on the guide rods and lock into position. Using lever
handle, bring pipe ends together against the facer, watching the gap
between the facer stops and the pipe clamping jaws. Leave enough
gap so that proper face-off will be achieved when the facer stops are
bottomed out against the clamps. Tighten the pipe clamp knobs until firm
resistance is felt. Do not over-tighten.
NOTICE:
Thoroughly clean all dirt and debris from pipe ends before
facing.

Facing the pipe
Turn facer handle counterclockwise and apply firm pressure on lever handle.
Continue facing until facer stops have bottomed out against the clamping jaws.
Stop rotation of facer.
Unlatch and remove facer. Remove shavings from pipe ends and machine.
Do not touch faced pipe ends.
Inspect both pipe ends for complete face off. If the face off is incomplete,
return to
Loading Pipe Into Machine .

the jaws.
