2.0 - SPECIFICATION 2.1 - General Specification The Maxi Chain Driven Cutting and Bevelling Machine is designed to manually rotate an oxygen/fuel machine cutting torch around pipes 4” (102 mm.) and larger in diameter. The Maxi Chain Machine can be used with any gas cutting machine torch (acetylene, Butane, propylene, natural gas or propane gas) or machine having a diameter of 30 or 35 mm. Pricing for propane or acetylene machine cutting torch is available. If vertical adjustment of the Gas Cutting Torch is necessary a Rack can be added to the Gas Torch.
2.2. - Features The Maxi Chain Machine Frame, which is an alloy aluminium casting, is fitted with a Forwarding Device, Tensioning Cam Handles, Wheels and a Rack Holder-Floating Device to support the Torch. The Maxi Chain Machine is attached to the pipe being cut by means of a 3-Mesh Chain. The Forwarding Device rotates the machine around the pipe during the cutting operation. Two (2) Hand Cranks are used to move the Forwarding Device composed of a Worm Screw and a Bronze Toothed Rim that are joined to the Chain Pinion. Two Tensioning Cams provide tension to the chain to fix the machine to the pipe. The Forwarding Device moves upward on two ALUMINUM columns as tension is applied to the Chain. The Rack Holder Floating Device provides movement perpendicular to the machine line of travel and a Knob with Pinion Positions it.

3.0 - OPERATING INSTRUCTION 3.1 - Chain Length
Drive Chain Length required is determined by the diameter of pipe to be cut. Table 1 of Section 2.2 shows the chain length for various diameters of pipe. See the Calculation Formula on our web site at www.mathey.com or contact for other diameters of pipe other than those listed. 3.2 How to Lengthen/Shorten the Drive Chain. From Table 1 of Section 2.2, select the Drive-Chain length required. If the chain length is incorrect, proceed as follows: - To Lengthen the Drive-Chain. - Select the chain segments required to extend the chain to the length mentioned in Table 1 of Section 2.2. - Join the Chain Segments with Chain Junction Link (Item N° - 21D) or Joint Bolt (Item N° -21A) and Nut (Item N° - 21B). In some instance it may be necessary to use the False Link (Item N° - 21C) - Set the Chain Segment, which is the proper length in the Chain Unpinning Block (Item N°-20B) and remove the Chain Pin with the Pin Extractor (Item N° - 20A). If one pin is removed the chain is joined with the Joint Bolt (Item N° - 21B) and Nut (Item N° - 21A). If two pins are removed the chain is joined with the Chain Junction Link (Item N° - 21D). - Check the Chain Ends to make sure that they meet your application requirement. For Male/female Chain Ends Joint Bolt (Item N° - 21B) and Nut (Item N° - 21A) and for Female to Female Chain Ends use Chain Junction Link (Item N° - 21D). Note: In some instances it may be necessary to use False Link (Item N° - 21C) in order to obtain the proper chain length. - To shorten the Drive Chain. - Select the Chain Segments required to shorten the chain to the length mentioned in Table 1 of the Section 2.2. - Set the Chain Segment, which is the proper length in the Chain Unpinning Block (Item N° - 20B) and remove the Chain Pin with the Pin Extractor (Item N° - 20A). If one pin is removed the chain is joined with the Joint Bolt (Item N° - 21B) and Nut (Item N° - 21A). If the two pins are removed the chain is joined with the Chain Junction Link (Item N° - 21D). - Check that the Chain Ends to make sure that they meet your application requirement. For Male/Female Chain Ends Joint bolt (Item N° - 21B) and Nut (Item N° - 21A) and for Female to female Chain Ends use Chain Junction Link (Item N° - 21B). Note: In some instances it may be necessary to use False Link (Item N° - 21C) in order to obtain the proper chain length. 3.3 Cutting 16” Pipe Diameters and Smaller with the Maxi Chain Machine. Check the area where the Maxi Chain Machine Wheel and Chain will be placed on the pipe for concave or convex areas on the pipe surface, before placing the machine on the pipe -remove as much of the deformity that is allowed by the welding specification. Set the machine on the portion of the pipe that is to remain on the Pipe Stand, with the Wheels of the Torch Arm side of the machine about 6” - 8” (152203mm) away from the cut line. The distant from cut line to the Wheels is dependent on the Torch Bevel Angle. Warning: Unrepairable damage to the Maxi Chain Machine will occur if the machine is placed on the portion of the pipe to be cut off. - Pull the Drive Chain through the cavity between the Sliding Core (3M) and the Sprocket (Item N° - 4A) until 12” – 18” of the Chain is protruding out of the other side. - Lay the Chain to rest on the Sprocket (Item N° - 4A). - Connect the Chain Ends. - Rotate the Tensioning Levers simultaneously applying tension to the Chain. - For a square cut, rotate the Maxi Chain Machine one (1) full turn around the pipe to insure the chain is perpendicular to the outside diameter of the pipe. - The Chain Machine is now ready for the installation of the Fuel Torch.
Note: If the pipe is spiral welded, excessively out of round or is in the vertical or oblique position, see instructions for the Installation of the Guide Strip. 3.4 The Maxi Chain Machine Guide Strip is recommended when cutting pipe under the following conditions. If the pipe to be cut is spiral welded, severely out of round, in the vertical position or oblique position, when cutting pipes larger than 18” (457mm), it will be necessary to use a Guide Strip to fit the Guide Belt. - Check the area 8” - 18” (203 - 457mm) away from the cut line where the Maxi Guide Strip will be placed on the pipe for concave or convex areas in the pipe surface. Remove as much of the deformity that is allowed by the welding specification. Warning: Placing the machine on the portion of the pipe that is being cut off will result in unrepairable damage to the Maxi Chain Machine. - Form all sections of the Guide Strip as close as possible so that they fit the pipe diameter to be cut. The better the sections of the Guide Strip fit the diameter of the pipe; the easier it will be to latch the ends of the Guide Strip together. - Attach the sections of the Guide Strips together as shown in Figure 3 with the Washer (Item N° - C1) in between the Band End Pivot Points and insert the Pins (Item N° - C2). When assembled, the section containing the Latch Handle Assemblies (Item N° - B) should be at one end of the assembled Guide Strip and the section containing the Latch Receiver (Item N° - A) should be at the other end. Repeat this step for each section to be assembled.
- It may be necessary to move the Latch Handle Assemblies in order for the Guide Strip to fit tightly around the Pipe. To move the Latch Handle Assemblies (Item N° - B) to their proper location, remove the Countersunk Screws and Domed Nuts (D) from the Latch Handle Assemblies (Item N° - B) shown in Figure 4 and remove the Latch Assemblies from the Guide Strip. - Place the section (Item N° - G) containing the Latch Handle Assemblies (Item N° - B) over the section containing the Latch End (Item N° - A). - Fold the Latch Handles (Item N° - E) of the Assemblies over until it touches the Screws (Item N° - F) of the Latch Adjustment. - Place the end of the Latch Adjustment Screws (Item N° - F) of the Latch Handle Assemblies (Item N° - B) into the curved portion of the Latch Receiver (Item N° - A). - Locate the nearest holes in Section G of the Guide Strip and mark them. - Place the Latch Handle Assemblies (Item N° - B) Base over the marked holes and insert
- Countersunk Screws and Nuts (Item N° - D) in the Latch Handle Assembly Base. Tighten the Domed Nuts on the Screws. - Again place the section containing the Latch Handle Assemblies (Item N° - B) over the section containing the Latch End (Item N° - F). - Place the end of the Latch Adjustment Screws (Item N° - F) of the Latch Handle Assemblies into the curved portion of the Latch Receiver (Item N° - A). - Adjust the end of the Latch Adjustment Screws (Item N° - F) until the Handle of Latch Handle Assembly Locks in position. Note: A large amount of pressure should not be used to close the Latch.
Warning: The Latch should not be forced closed as this will cause damage to the Latch or deform the end of the Receiver Section. Place the Wheels (Item N° - 11D) of Maxi Chain Machine over the Guide Strip. Pull the Drive Chain through the cavity and over the Sprocket (Item N° - 4A), until 12” – 18” of the Chain is protruding out the other side of the Cavity. Lay the Chain (Item N° - 21) to rest on the Sprocket (Item N° - 4A) Place the Chain between the Dome Nuts located near the center of the Guide Strip. Connect the chain ends. Rotate the Tensioning Levers (Item N° - 8E) simultaneously applying tension to the Chain. Cut the Chain to length and insert the Conn-link. The Maxi Chain Machine is now ready for installation of the Fuel Torch.
