Key Features of Coats Tyre Changing Machines

Advanced Mounting/Dismounting Systems

• Swing Away Arm: Most Coats machines are equipped with a swing away arm, allowing quick, safe access to mount or demount tires, and enabling efficient workflow in restricted spaces.
• Tabletop Rim Clamp: Securely holds a wide rim diameter range (typically 6″–24″), accommodating most modern wheels.

Bead Loosening Technology

• Foot and/or Hand Control Bead Loosening: Choose between foot pedal or hand lever action, providing flexibility for operator comfort and control. This reduces fatigue and increases precision.
• High Pressure Dual Nozzle Bead Sealing: Quickly and securely inflates tire beads to seat the tire efficiently—especially vital for stiff or large sidewalls.

Robust Power Options

• Electric and Air Motor Variants: Select from 110V, 220V, air-powered, and even dual-speed versions, so your machine can match your shop’s power supply and operational needs.
• High Horsepower: Motors up to 2 HP provide the strength needed for demanding tire assemblies and expedite service.

Helper Devices and Protection

• Robo-Arm® and RoboRoller: Articulated helper arms and bead depressors provide extra force and leverage, enabling safe mounting of low-profile, run-flat, and specialty tires with less technician effort.
• Polymer/Nylon Duckhead: Prevents metal-to-metal contact with the rim for damage-free service.
• Wheel Protection Accessories: Includes bead loosener socks, plastic clamp protectors, and mount/demount tool socks.

Durability and Construction

• Heavy-Duty Chassis: Coats machines are tested for extreme durability, boasting up to 250,000 cycle longevity in harsh conditions.
• Built-in Storage: Many models include handy cabinets or holders for tools and supplies, keeping your workspace organized.

Usage and Safety: Tips for Home and Hobbyist Environments

While Coats tyre changing machines are designed for demanding commercial environments, many features make them accessible and safe for hobbyists and home garage users:

Setup and Safety Precautions

1. Correct Positioning: Always place the machine on a stable, level surface. Allow adequate clearance around the unit to avoid workspace hazards.
2. Proper Electrical/Air Supply: Ensure your power supply matches the machine’s requirements. For air-powered models, a compressor maintaining 110–175 psi is typically needed.
3. Secure Operation: Use the clamp and bead loosening systems as instructed—never bypass safety mechanisms or force parts.
4. Personal Protective Equipment: Always wear gloves, safety glasses, and avoid loose clothing when operating any tire changer.
5. Regular Maintenance: Keep moving parts clean and lubricated, inspect for worn accessories, and replace damaged items immediately.

Operating the Machine

• Read the Manual Thoroughly: Coats provides comprehensive manuals and videos for every model—always review before first use.
• Clamping and Demounting: Place tires carefully onto the table top, making sure the rim is properly centered and clamped.
• Using Helper Arms: Deploy the Robo-Arm® or similar devices when working on run-flat or low-profile tires—this is crucial for safety and to prevent rim/tire damage.
• Bead Inflation: Use the high pressure dual nozzle or bead sealing system for efficient seating, but monitor pressure to avoid over-inflation.

Practical Tips and Best Practices

Choosing the Right Model

• Assess Tire Range: Choose a model that matches the biggest and smallest tire/wheel you expect to handle. For most home users, a machine with a 6″–24″ rim range is sufficient.
• Volume of Use: Occasional use (home/hobbyist) may warrant an entry-level or mid-range Maxx or RC unit; daily/professional setups benefit from higher-end (Maxx 80/90, 90C, APS 3000) machines.
• Power Supply: Double-check your garage/shop’s electrical or air setup—select a model compatible with your infrastructure.
• Accessory Compatibility: Ensure availability of replacement parts and protection accessories. Poly/Nylon duckheads and wheel protection kits prolong both wheel and machine lifespan.

Using Your Tire Changing Machine Efficiently

• Pre-Inspect Tires and Wheels: Clean debris and check for rim/tire defects before mounting.
• Lubricate Beads: Use bead/assembly lube liberally to prevent binding and damage during mounting/demounting.
• Adjust Helper Arms As Needed: On tougher applications, position Robo-Arm® or roller helpers precisely for maximum effectiveness.
• Do Not Rush: Allow the machine’s features to do the hard work—never force the action or bypass built-in assists.
• Regularly Inspect Clamps and Tooling: Replace worn plastics/protectors to keep both your machine and wheels in top condition.

FAQ

1. What size wheels can I service with a Coats tyre changing machine?
   Most Coats machines handle external rim diameters from 6″ to 24″, suitable for the majority of passenger vehicles, light trucks, and SUVs. Specialty models and accessories allow for even larger or smaller wheels.

2. Are these machines suitable for home or hobbyist use?
   Yes. Entry-level and compact models like the RC Series or Maxx 50 are ideal for home garages and hobbyists, offering professional-level results in a smaller footprint.

3. What is the benefit of the Robo-Arm® and similar helper tools?
   Helper arms, like Robo-Arm® and RoboRoller, provide the extra pressing force needed to work with stiff sidewalls, run-flat, or low-profile tires. They reduce technician fatigue and minimize the risk of wheel damage.

4. Can I change run-flat or specialty tires with these machines?
   Yes, particularly with Maxx 70, Maxx 80/90, and specialty models like APX 90 or APS 3000. These units include advanced helper devices and stronger construction to handle tough tire assemblies.

5. How do I know whether to choose an electric or air-powered model?
   Select based on your shop’s infrastructure. Electric units (110V or 220V) are plug-and-play for most users. Air-powered machines require an air compressor (typically 110–175 psi)—ideal for shops already equipped for pneumatic tools.

6. How important are accessory kits and upgrade parts?
   Using proper accessories—like nylon/polymer duckheads and rim guards—prevents rim and tire damage, prolongs machine life, and protects your investment.

7. What safety practices should I follow?
   Always use personal protective equipment, follow the operation manual, inspect your machine regularly, and never bypass built-in safety devices or force parts beyond their intended motion.

8. What maintenance does a Coats tire changer require?
   Routine lubrication, cleaning of moving parts, periodic inspection of clamps and duckheads, and prompt replacement of worn accessories ensure optimal performance and safety.

9. Can one person operate these machines safely?
   Absolutely. Most models are designed for efficient single-operator use, and helper arms minimize the need for additional hands even on tough tires.

10. Are Coats tyre changers compatible with all tire types and vehicles?
    They’re compatible with almost all standard passenger car, light truck, and SUV tires. Always check the max rim width and diameter; for larger, commercial, or specialty tires, select models or options designed specifically for those applications.
