Learning Objectives

By course end, participants will:

• Operate Hunter tire changers (table-top TCX55/56/57/59 and similar models) to mount/demount tires on wheels of various sizes.
• Perform correct procedures: break beads, use traditional or leverless heads, inflate beads, and use assist arms/adapters with proper safety and lubrication.
• Identify and use required accessories: protective heads/inserts, jaw covers, wheel lift, inflation tools (e.g. rapid inflation jets).
• Execute routine maintenance: daily checks (drain moisture, inspect wear parts) and periodic tasks (refill oiler, tighten bolts) per Hunter guidelines.
• Troubleshoot common issues: diagnose symptoms (e.g. no rotation, air leaks, bead stuck) and apply remedies (check motors/wiring, replace seals, use plastic head to avoid rim damage).
• Demonstrate safety compliance: proper PPE, never exceed tire pressure limits, no body parts over wheel during inflation.
• Use checklists for operation and maintenance, and complete written quizzes and practical tests.

Each objective is measurable (e.g. “Student will clamp and break beads on a test wheel without supervision”).

Course Syllabus and Module Plans

The course is organized into modules with lesson plans, durations, and exercises:

Module 1: Safety & Equipment Overview (2 hours)

• Topics: Shop & personal safety (PPE, hazards), reading decals/manuals. Introduction to Hunter models (TCX table-top vs Revolution; leverless vs traditional heads). Key components: turntable, bead breaker, mounting head, inflation system, pedals.
• Hands-On: Identify parts on a TCX machine, practice lockout/tagout. Interpret warning labels (e.g. “Keep away from moving parts”).
• Learning Goal: Students can list major machine parts, cite two safety rules (wear eye protection; remove valve core before breaking bead), and lock out power for maintenance.

Module 2: Tools, Accessories & Setup (1 hour)

• Topics: Required tools (RP11-3009516 bead lever, RP6-3784 tire paste, air chuck 145-341-2, Hunter Lubri-Oil 148-133-2, etc.). Hunter parts list: mounting heads (plastic winged RP11-8314813), steel head kits, jaw/wheel protectors (RP11-8-11100358, RP11-8-11400098 sleeves). Use of wheel lift, adapters (jaw extender RP11-8-11100402, motorcycle kit RP11-2201113). Setup procedure: secure machine, attach foot pedal harness, adjust clamps.
• Hands-On: Install a new polymer head, apply jaw protectors, fit jaw extenders. Check air pressure/regulator.
• Learning Goal: Students will assemble and identify key accessories, and prepare the machine for operation.

Module 3: Clamping & Bead Breaking (2 hours)

• Topics: Mounting wheel: position wheel on turntable, center it (bottom bead in drop center). Explain external vs internal clamping (TCX uses external clamps 10–26″). Use foot pedal to close clamps. Remove valve core to deflate tire.
• Bead Breaker Operation: PowerOut™ bead breaker (on handle or pedal) – “In” to break bead, “Out” to retract. Position shovel 1–2″ from rim, on sidewall. Break top bead, rotate wheel 180° and break other side. Repeat for bottom bead with wheel tilted.
• Safety: Keep limbs clear of bead breaker; wear glasses during operation.
• Hands-On: Practice clamping and breaking top/bottom beads on a test tire. Instructor supervises correct shovel placement.
• Learning Goal: Student can clamp a wheel and break both beads safely.

Module 4: Demounting Procedures (2.5 hours)

• Topics: Top Bead Demount: For TCX57 (leverless): swing bead lifter head to rim edge, lower it to lift bead off rim with rotation. For TCX56 (traditional head): use plastic-sleeved bead lever between head lip and bead, pry up, then spin wheel to rotate bead off. Bottom Bead Demount: Tilt wheel, use bead lever or secondary roller, pull lower bead over head lip, spin to remove.
• Advanced: Using bead press assist: flip-down arms and rollers on TCX57/56 help hold beads down. Locking lower arm on TCX56 can lock disk for stubborn beads.
• Hands-On: Each student demount the top bead from a tire. Instructor demonstrates both traditional and leverless methods. Then demount the bottom bead.
• Learning Goal: Student can remove both beads from a wheel with minimal rim stress.

Module 5: Mounting Procedures (2 hours)

• Topics: Insert new tire over rim edge. Seat bottom bead: ensure bead lip is on rim, rotate turntable to mount. Then seat top bead: position bead under mounting head; lift or pry as needed. Use lubrication liberally.
• Inflation: Use inflation foot pedal/jets to seat beads (hold safety cage or stand clear). First use a short burst to seat bead (maintain bead in drop center), then fully inflate to recommended pressure (never exceed sidewall max). Reinstall valve core.
• Advanced Tips: Use Hunter FastBlast inflation on models equipped (TCX59) for tough beads. If bead resists, use helper arm or flip-down roller on TCX57.
• Hands-On: Students mount a tire, use inflation pedal, and check seating. Time is given to practice and compare methods (e.g. single vs dual bead press).
• Learning Goal: Student can mount a tire and inflate it correctly to spec, demonstrating safe inflation practices.

Module 6: Accessories & Special Procedures (1.5 hours)

• Topics: Assist Arms: When to use mobile assist arms or TCX’s Adaptive Dismount Device for heavy wheels. Wheel Lift: Demo optional wheel lift (if available) for truck/SUV wheels. Adapters: Switch clamps to wider range using adapter kits (3″ reducer for small rims). Use internal vs external clamping for reverse wheels. Tubeless Inflation: If machine has tubeless inflation feature, instruct on its use.
• Hands-On: Using provided assist arm (or improvised technique) to handle a large tire. Attach/detach jaw adapters and demonstrate function.
• Learning Goal: Students know how to configure machine and use attachments for less-common tire/wheel scenarios.

Module 7: Maintenance & Troubleshooting (3 hours)

• Topics: Review Hunter maintenance schedule: Daily: drain regulator moisture, inspect rubber/nylon parts (tool supports, pads, lever protector), clean rim-contact areas. Weekly: clean machine (vacuum shop towel; no compressed air), check fasteners. Monthly/Periodic: refill oiler with Hunter Lubri-Oil 148-133-2, set drip-rate (1 drop/3 turns), inspect cylinders. Annual: thorough safety audit (check foot pedal valves, replace worn hoses/seals).
• Troubleshooting: Common issues with fault symptoms and fixes:
  • Machine won’t spin: Check power/wiring, test motor (may need replacement).
  • Pedals inert: Inspect air supply and pedal valve (tighten fittings).
  • Bead breaker fails: Ensure tire fully deflated (remove core) and adequate air (≥8 bar). Check oiler and seals.
  • Scratching wheels: Use plastic head or steel head inserts; always install jaw/shovel protectors.
  • Air leak: Isolate leak to hoses/valves, tighten or replace.
  • Inflation gauge dead: Replace battery.
• Hands-On: Students perform a “daily check” on a demo machine: drain moisture, replenish oil, tighten clamps. Then troubleshoot a pre-planted fault (e.g. a loose fitting causing air leak).
• Learning Goal: Students will complete a maintenance checklist and successfully diagnose at least one simulated fault.

Maintenance Schedule Chart

Module 8: Assessment & Certification (1.5 hours)

• Written Quiz: Multiple-choice and short-answer on safety rules, steps, and maintenance (example: “What is the part number for Hunter Lubri-Oil?” Answer: 148-133-2).
• Practical Exam: Student must perform a full tire change on a training wheel within set time, using checklists. The rubric (provided to instructors) covers safety (PPE, stand clear), correct clamp use, lubrication, mounting/demounting technique, inflation procedures, and housekeeping.
• Certification: Successful students receive a completion certificate. Remedial instruction is given for any failures.

Safety Protocols and Checklists

• Always wear safety goggles and gloves. Ensure machine is grounded and air supply clean.
• Check machine condition before use (hoses, guards, oiler level). Drain moisture daily from regulator.
• Stand to side, never above wheel during inflation. Do not exceed tire pressure listed on sidewall. Use protective cage if available.
• Print and use the Daily Maintenance Checklist and Change Procedure Checklist (see Appendix).

Instructor Notes & Handouts

• Notes: Emphasize that Hunter’s PowerOut™ bead breaker uses fingertip controls. Encourage students to practice each step repeatedly. Make clear that machine-specific procedures (e.g. leverless head use) must follow the manual exactly. Class size is unspecified; adjust lab group sizes as needed.
• Handouts: Provide students with: step-by-step change flowchart, safety poster (key warnings), maintenance schedule table, and parts reference table.

Table: Selected required tools and Hunter part numbers for consumables and parts used in training.

Troubleshooting Guide (Symptoms & Fixes)

• Machine will not spin: Check power circuit and wiring; test motor by hand. If burned out, replace motor.
• Turntable rotates one way only: Examine foot-pedal switch and wiring (loose connection possible).
• Pedals are weak/inoperative: Inspect air connections at pedal block, ensure full shop air pressure (at least 80–100 PSI). Lubricate pedal pivots.
• Bead breaker does nothing: Ensure tire is fully deflated and valve core is removed. Verify incoming air pressure is ~8 bar. Check oiler and seals (lack of oil can cause piston failure).
• Tire scratches rims: Replace steel mounting head with plastic winged head. Always install rubber jaw covers and bead-shovel covers.
• Air leak detected: Depressurize, find hissing around hoses/fittings. Tighten or replace faulty couplers/cylinders.
• Beads won’t seat: Use inflation jets carefully (keep hands clear) to assist seating. Double-check that rim and tire match diameter (never mix mismatched sizes).

For detailed diagnostics, instructors should refer to the Hunter Service Manual for fault codes and disassembly steps.
