SECTION IGENERAL DESCRIPTION:Your CLINCHER® Bucking Unit is a rugged, self-contained, continuouslyrotating unit designed to accurately make-up or break-out thethreaded connections on tubular components such as oil and gaswell drilling tools, casing, tubing, and similar equipment. The unit willaccurately make-up and break-out thread connections without damageto the thread.Recommended Safety GuidelinesThe safety guidelines that follow are recommended by SuperiorManufacturing & Hydraulics, and are in no way intended to supersedethe specific health and safety regulations and guidelines of ourclient’s workplace. Workplace rules and regulations are the responsibilityof the client.A. Work ApparelTo ensure employee safety, it is recommended that the followingPPE (Personal Protective Equipment) be worn when using and workingaround hydraulic equipment:1. Eye Protection (safety glasses)To avoid risk of eye damage due to:• fracture/failure of die inserts under load• fracture/failure of tool under load• failure of hydraulic hose or component under pressure2. Ear Protection (ear plugs)To prevent hearing damage due to:• electric motor and hydraulic systems noise• sudden and loud noises that may occur during the workprocess3. Head Protection (hard hat)To reduce danger due to:• overhead cranes and hooks• fracture/failure of die inserts under load• fracture/failure of tool under load4. Hand Protection (leather gloves)To avoid danger due to:• metal slivers on the tool or dies produced during thework process• chemicals used during the work process• failure of hydraulic hose or components under pressure5. Foot Protection (steel-toed boots)To prevent injury due to:• falling or rolling work piecesSECTION IIINSTALLATION:1. Inspect unit carefully for shipping damage or missing parts.2. Position unit on a fairly flat and level floor leaving sufficientclearance on both ends to allow the insertion and removalof the longest tools expected to be serviced.3. Anchor the unit in place.4. Clean hydraulic hoses and quick disconnects.5. Attach all hoses that connect the control console to theBucking Unit.6. Fill hydraulic reservoir with recommended hydraulic fluidfiltered using 3 micron filter system. Filler cap/breatheris accessible on left side of unit. Level indicator may beviewed through a window in front.7. Verify suction valve is open if present.8. Fill pump case with filtered hydraulic oil before connectingpower.9. CAUTION: Check that main power supply matches nameplate rating on motor in control console. Use of an incompatiblepower source will result in equipment damage andwill void warranty.START UP:10. Connect power supply.11. Check motor rotation by jogging start/stop switch quickly.Reference the rotation plaque attached to the power unit.If rotation is incorrect, switch any two-phase wires at motorstarter.1. Ensure both pressure relief valves are fully rotated counterclockwiseto reduce pressure to minimum.2. Start motor and check for oil leaks in console. Hold backBackup Clamp Cylinder control lever in Open/Retract positionand adjust Clamp Pressure Control until system pressurereads 1,000 psi. Cycle all valves fully several times tocompletely purge all air from the system.3. Check Bucking Unit and Hydraulic Power Unit for leaks.4. Check reservoir for proper fluid levels. Add filtered hydraulicfluid if level is below sight glass when all cylinders are extended.Fill until fluid level reaches midpoint in sight glass.If fluid level is below sight glass level, unit will not operate.SECTION IIIOPERATIONThe E-Stop is located on the control console, and must be pulled outfor the unit to operate. Locate the start button on the motor starter.Push to start main drive motor.1. Start the motor.2. Move Tong Make Up / Break Out lever in either directionuntil the power tong completes a rotation.3. Hold Tailstock Clamp / Unclamp lever in the Unclampposition and adjust Clamp Pressure Control until systempressure reads 1,000 psi. Cycle all levers fully several timesto completely purge all air from the system.4. Position work-piece near center of Headstock, shift theTailstock Clamp / Unclamp lever to the Clamp position.Tailstock Clamp / Unclamp control lever must be left in the‘Clamp’ position while work-piece is in machine.5. Position Tailstock as close as possible to tong, allowingrequired space for thread travel. CAUTION: If adequatespace is not left to accommodate thread travel, the backupwill contact the tong, potentially damaging the equipmentor tubular connection. Such damage is not covered by thewarranty.6. Shift Headstock Clamp / Unclamp lever into Clamp position.7. Using Tong Make Up / Break Out control lever, apply makeupor break-out torque, then rotate headstock.MAKE-UPWhen making up connections, set relief valve to proper settingbefore rotating headstock.BREAK-OUTSet relief valve to proper setting before rotating headstock.2
SECTION IVMAINTENANCEDAILY:1. With all clamp cylinders fully extended, check hydraulicreservoir oil level on sight glass on front of console. Fill withfiltered hydraulic fluid if needed until level reaches midpointon sight glass.2. Inspect die inserts. Clear any debris from around clampcylinders.WEEKLY:1. Remove dies and inspect jaw retainer bolt torque. Torqueshould be set to 180 ft-lbs.MONTHLY:1. Grease fittings.65”70”ANNUALLY (or following any system repair):1. Drain and clean hydraulic reservoir. Analyze contamination/ quality status of hydraulic oil (with the use of an analysiskit or by other third party means). Filter / replace oil asrequired.2.3.Remove and clean suction strainer.Refill reservoir with new filtered hydraulic oil.99”SECTION VHYDRAULIC POWER UNIT153”The hydraulic power unit incorporates a number of pressure controland relief valves. These valves are correctly adjusted and set prior toshipment from our factory.CAUTION: Adjusting internal relief valves or pump compensator settingswill void warranty.52”SECTION VISPECIFICATIONS85” 42”Console / Power Unit:Electric Motor: 50 Horsepower, 440 Volt, 3 phase, 60 HertzHydraulic Oil: AW-68Hyd.
