2.0 GENERAL INFORMATION
2.1
2SA 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 6”/152.4mm, 8”/203.2mm, 10”/254mm and 12”/304.8mm horizontal nominal size API line pipe. The
machine comes with Spacer Bolts or Step Spacers 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 special training providing they read and understand the parts and
operating manual. The 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.
