Page 7: Safety Alerts
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
Fusion 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. FEEL any changes in the way the equipment operates. -
Page 9: Electric Motors Are Not Explosion Proof
Fusion Equipment Safety Electric Motors are Not Explosion Proof Electric motors are not explosion proof. Operation of these components in a hazardous ¡PELIGRO! environment without necessary safety precautions will result in explosion and death. The armature brushes must be removed from the electric motor when manually operating in a hazardous condition. -
Page 10: Heater Is Hot
Fusion Equipment Safety Heater is Hot The heater is hot and will burn clothing and skin. Keep the heater in its insulated heater stand or blanket when not in use, and use care when heating the pipe. NOTICE: Use only a clean non-synthetic cloth such as a cotton cloth to clean the heater plates. -
Page 11: Positioning Fusion Machine
Fusion Equipment Safety Positioning Fusion Machine Place fusion machine on as level ground as possible, and set the brake on the rear wheel. If it is necessary to operate machine on unlevel grade, chock the wheels and block the unit to make it as stable as possible. -
Page 12: Overview
Overview Theory of Heat Fusion The principle of heat fusion is to heat two surfaces to a designated temperature, and then fuse them together by application of force. This pressure causes flow of the melted materials, which causes mixing and thus fusion. When the polyethylene pipe is heated, the molecular structure is transformed from a crystalline state into an amorphous condition. -
Page 13: Pitbull No.14 Cart
Overview PitBull No.14 Cart The PitBull No.14 fusion machine can be mounted on a No.14 four wheel cart for mobility and movement along the pipe line. There is a clamping wheel lock on the left rear wheel to prevent rolling. The cart is not designed for over-road towing. -
Page 14: Reversible Jaws & Levers
Overview Reversible Jaws & Levers The No. 14 PitBull upper jaws and control levers are reversible from one side to the other. This allow the machine to be operated from either side. The jaws and clamp knobs can be removed by using a pair of snap ring pliers to release the hinge pins. -
Page 15: Electric Facer
Overview Electric Facer The facer is a McElroy Rotating Planer Block Design. The blade holders each contain two cutter blades. The block rotates on ball bearings and is chain driven (enclosed in lubricant) by a heavy duty electric motor. When operating in a hazardous environment, operate the facer manually. -
Page 16: Heater
If this occurs, disconnect power and have the heater repaired by a McElroy Authorized Service Center. The heater temperature is controlled by a microprocessor. It has a red indicator light on the handle at the bottom of the temperature scale. -
Page 17: Operation
Operation Read before Operating Before operating this machine, please read this manual thoroughly and keep a copy with the machine for future reference. The fusion procedures in this manual are for use with the polyethylene pipe. If fusing other thermoplastic pipe materials, refer to the pipe manufacturer's suggested procedures or appropriate joining standard. -
Page 18: Install Clamping Inserts
Operation Install Clamping Inserts Select and install appropriate clamping inserts for the pipe that is being fused. For use with 4" DIPS pipe the 4" IPS masters inserts must be removed. Pull the spring pins out of their hole and rotate them outward putting the pin in the jaw pockets. -
Page 19: Positioning Pipe In Machine
Operation Positioning Pipe in Machine Position the facer on the guide rods and lock into position. Using lever handle, bring pipe ends together against the facer, watching the gap between the facer stops and the pipe clamping jaws. Leave enough gap so that proper face-off will be achieved when the facer stops are bottomed out against the clamps. -
Page 20: Check Alignment Of Pipe
Operation Check Alignment of Pipe Bring the pipe ends together under sufficient force to overcome any pipe drag or friction in the system. Check for alignment and proper face off. If high/low (misalignment) exists, adjust by tightening the clamp on the high side and reface the pipe. NOTICE: When clamping, do not over-tighten the clamp knobs because machine damage can result. -
Page 21: Inserting Heater
Operation Inserting Heater Heater Is Not Explosion Proof. This unit is not explosion proof. Operation of heater in a ¡PELIGRO! hazardous environment without necessary safety precautions will result in explosion and death. If operating in a hazardous environment, heater should be brought up to temperature in a safe environment, then unplugged before entering the hazardous atmosphere for fusion. -
Page 22: Optional Use Of Torque Wrench
Operation Optional Use of Torque Wrench When a specified Interfacial Pressure is required in the fusion procedure, a torque wrench can be used. IMPORTANT: Use a torque wrench with the No.14 PitBull place an adapter in the lever socket (Part # 410802). A 1/2" drive 100 ft-lb 15.0"... -
Page 23: 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. TX00428-8-10-95 Cleaning the Machine Clean the machine with a soap and water wash as needed. -
Page 24: Remove Dirt
Maintenance Remove Dirt Remove dirt from jaw and insert serrations and clamp knob eyebolts. TX00865-1-30-96 Clean and Lubricate Bearings All clamp knobs are equipped with thrust bearings to reduce friction and improve efficiency of the clamping screw. Keep these bearings clean by washing in kerosene or solvent. They should be lubricated with light machine oil. -
Page 25: Installing Butt Fusion Heater Adapters
Maintenance Installing Butt Fusion Heater Adapters The heater body of this assembly is not coated. Coated butt fusion heater plates are available for all butt fusion applications. Butt fusion heater adapters are installed with eight Stainless Steel Cap Screws. Care should be taken to assure that the butt fusion heater adapters are seated on the heater body, and that there is no foreign matter trapped between these surfaces. -
Page 26: Heater Indicator Light
If the heater is not operating properly, the control will attempt to turn the heater off and the indicator light will flash rapidly. If this occurs, disconnect the power and take it to a McElroy Authorized Service Center for repair. -
