Installing Pipe In Threading Machine
1.Check to insure the cutter, reamer and die head are swung to UP position.
2.Mark the pipe at the desired length if it is being cut to length.
3.Insert the pipe into the Threading Machine so that the end to be worked or the cutting mark is located about 12 inches to the front of the speed chuck jaws.
4.Insert workpieces less than 2 feet long from the front of the machine. Insert longer pipes through either end so that the longer section extends out beyond the rear of the Threading Machine.
WARNING To avoid equipment
5.Tighten the rear centering device around the pipe by using a counterclockwise rotation of the handwheel at the rear of the Threading Machine. This pre- vents movement of the pipe that can result in poor thread quality.
6.Secure the pipe by using repeated and forceful counterclockwise spins of the speed chuck hand- wheel at the front of the Threading Machine. This action “hammers” the jaws tightly around the pipe.
