Page 7: Equipment Safety
Follow all applicable federal, state, local, and industry specific regulations. McElroy Manufacturing, Inc. cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this manual and on the machine are therefore not all inclusive. -
Page 8: General Safety
Equipment Safety General Safety Safety is important. Report anything unusual that you notice during set up or operation. LISTEN for thumps, bumps, rattles, squeals, air leaks, or unusual sounds. SMELL odors like burning insulation, hot metal, burning rubber, hot oil, or natural gas. -
Page 9: Fuel Handling
Equipment Safety Fuel Handling Gasoline and diesel fuel are extremely flammable and their vapors will explode if ignited. ¡PELIGRO! Do not fill the fuel tank while the engine is hot or running, as spilled fuel could ignite. Refuel in a well ventilated area. Do not smoke or allow flames or sparks in the area where the engine is refueled, or where gasoline is stored. -
Page 10: Pipe Handling Safety
Equipment Safety Pipe Handling Safety Do not position yourself under supported or raised pipe or near the end of the pipe. Pipe could travel uncontrolled on the rollers in either direction and cause serious injury or death. In order to minimize the potential for the pipe to travel uncontrolled, keep the pipe level when it is placed on the rollers of the fusion machine and on the rollers of the pipe stand(s). -

Page 18: Align Pipe With Fusion Machine
• Lower the pipe stand by digging out underneath it. • Raise the fusion machine up with stable blocking. Large diameter pipe in a large MegaMc fusion machine, the pipe stand may not go low enough to align the pipe in the fusion machine jaws. - Page 19 1236, T900, 1648, 2065 and 1600 fusion machines. There is some capability overlap so this chart details all the combinations of pipe size and MegaMc fusion machines that can be used with the 8-36 and 36-65 MegaMc Hydraulic Pipe Stands.

Safety warnings: Do not exceed rated load or lift loads other than the McElroy MegaMc Hydraulic Pipe Stand with the lifting sling. Do not operate a damaged or malfunctioning lifting sling or one missing parts. -
Page 21: Lifting The Pipe Stand
Lifting and Storage Lifting the Pipe Stand Lifting A four cable lifting sling is provided for hook lifting the unit. The lifting sling must only be used by a person trained and qualified in its use. Before each lift of the machine, inspect the lifting sling for damage. Do not use a damaged lifting sling. The sling is to lift one stand only. - Page 22 Lifting and Storage NOTICE: Boom must be clear of fork loops. Move trolley to clear fork loop. Failure to move the boom may result in damage to pipe stand. Boom Fork Loop NOTICE: Ensure fork is clear of trol- ley lugs and is supporting the frame. NOTICE: Forks must be 6 feet long or longer and extend past the rear frame member...

Page 23: Stacking Stands
Lifting and Storage Stacking Stands Pipe stands of the same size can be stacked a maximum two high to reduce the floor space needed for storage or shipping. First lower the boom fully on both units and move the trolley away from the HPU to make the unit more balanced. Remove the guard rail from the unit that will stack on top by lifting up on the rail and pulling it out of its sockets on the base frame. -
Page 24: Extended Period Storage
Lifting and Storage Extended Period Storage If storing the pipe stand for an extended period of time, refer to the engine operator's manual for long term storage procedures. Grease all pins, wheels and bearings. Refer to the Maintenance section of this manual for lubrication procedures. TX03067-2-23-10 4 - 5... -
Page 25: Maintenance
Maintenance Preventative Maintenance To insure optimum performance, the machine must be kept clean and well maintained. With reasonable care, this machine will give years of service. Therefore, it is important that a regular schedule of preventive maintenance be kept. Store machine inside, out of the weather, whenever possible. Service intervals are approximate for average service and may need to be done more frequently in severe service conditions or can be done less frequently if used minimally. -
Page 26: Pipe Stand Lubrication
Maintenance Change Hydraulic Filter and Fluid The hydraulic filter should be replaced every year. The hydraulic fluid should be replaced every two years. Fill the reservoir from a clean container. Refer to the "Hydraulic Fluids" section of this manual for hydraulic fluid recommendations. -
Page 27: Lifting Slings
Maintenance Lifting Slings Before each lift of the machine, inspect the lifting sling for damage. Do not use a damaged sling. In addition, a thorough yearly inspection should be done by a qualified person per ASME Standard B30.9. In severe service it should be inspected more frequently than yearly. -
Page 28: Troubleshooting
Maintenance Troubleshooting Problem Action May need to replace lift cylinder seals. May need to replace counterbalance valve. • If counterbalance valve requires replacement: Lower pipe stand completely. Remove pipe from pipe stand. Load Lowers Turn valve adjustment fully clockwise. Slowly and carefully remove valve cartridge from valve body. May need to increase the counterbalance valve setting. -
Page 29: Hydraulic Fluids
Hydraulic Fluids Hydraulic Fluids The use of proper hydraulic fluid is mandatory to achieve maximum performance and machine life. Use a clean, high quality, anti-wear hydraulic fluid with a viscosity index (VI) of 135 minimum. It should have a maximum viscosity of 500 cSt (2000 SSU) at startup (ambient temperature) and a minimum viscosity of 13 cSt (65 SSU) at the maximum fluid temperature (generally 80°F above ambient). -
