Model 620SB Low Profile Clamshell, Air
92-0220 : Rev. 131230
Problem: The Clamshell is slipping on the pipe or tube
Probable causes:
The Clamping Pads are not in full contact with the pipe or tube.
The clamping pressure is too light.
Scale and/or other foreign material is present on the pipe or tube.
Weld seams, swelling, or bumps under the Clamping Pads are preventing
full contact.
Dull Tool Bits are causing extra force in the axial and/or radial direction.
The pipe or tube wall is too thin which allows the tube wall to flex and the
machine to move.
Problem: The Air motor will not start
Probable causes:
The air supply is shut off.
The Air Motor will not run free.
The Air Motor needs lubrication.
Add lubrication and do not run the Air Motor for a few minutes.
Then try again.
Tap on the Air Motor casing lightly with a piece of wood or with a soft rub-
ber mallet.
The vanes may be sticking.
Sand or other foreign material is in the vanes of the Air Motor.
