FREQUENTLY ASKED QUESTIONS
Short Answer: Replace as soon as you see any signs of wear or mushrooming. This can be as frequent as each shot, depending on jobsite conditions. Consult the user manual.
Correct use: Before and after each bore, inspect the coiled pins, and mating components for wear or deformation. Keep all contact surfaces clean, apply light grease where applicable, and replace pins that show wear to maintain smooth rotation and fast tool changes
Technical details: Coiled pins are designed to protect the Tri-Con connection by absorbing wear during operation. They are purposefully a wear-item to protect the integrity of the Tri-Con Connection.
Incorrect use includes: Reusing damaged or worn pins or allowing debris to build up in the connection. Incorrect use can introduce greater risk of poor fit, difficult tool changes, or reduced connection performance.
Short Answer: Eye swivels and duct pullers serve different purposes during pullback and are not interchangeable.
Correct use: An eye swivel is used when pulling product that already has an external pulling eye or adapter and needs to rotate independently of the drill string. A duct puller is used when the product must be gripped internally, such as conduit or duct without an external pulling attachment.
Technical details: Eye swivels manage rotation and help prevent product twist, while duct pullers create an internal mechanical grip inside the product itself. The correct choice depends on whether the product has an external pull point or requires internal engagement.
Incorrect use includes: Using an eye swivel when no external pull point exists or attempting to pull duct without proper internal grip. Incorrect use can introduce greater risk of slippage, product damage, or installation failure.
