2.0 General Information
2.1 3SA Saddle Machine is designed to rotate a 1 3/8”/35mm diameter 12” long oxy/fuel or plasma machine torch
to cut and/or bevel 12”/ 304.8mm, 14”/ 355.6mm, 16”/ 406.4mm, 18”/ 457.2mm and 20” / 508mm horizontal
nominal size API line pipe. The machine comes with Spacer Bolts for the above list pipe sizes. Spacer bolts are
available for other pipe or tubing sizes within the machine cutting range.
2.2 Operator Training – The Operator requires no training providing they read and understand the parts and
operating manual. Training mainly involves teaching the operator to smoothly and without hesitation rotate the
crank handle so the oxy/fuel or plasma torch produces a smooth even cut around the pipe.
2.3 Maintenance Personnel – Mathey Dearman offers a training course at its facility on the major machine repairs
at no charge. The parts and operating manual contains information concerning the lubrication and minor repair.

3.3 Place the spacer if require on the Spacer Bolt protruding through the top of the Saddle. Secure Spacer Bolts and
