2. Content Modular Technical Design F-1 Pit-Stop System Fast Components Exchange TRMS: Truck Repair Monitoring System Maintenance & Repair Sequence Electronic Data Collection Flowcharts: F-1 Pit-Stop System Component repairs Part repairs Unique Test Facility For Engines and Axles Workshop & Team What Automatic Data Processing Enables Global Technical Organization Summary

3. Major Components Conventional trucks: Each size has different major components (Engine, frame, axles, drive line, tires) All ETF trucks have the same major components (Power-Modules, Tires & Axle-Groups)

4. 95 % Technical Availability by Fast Component Exchange System! Maintenance & Repair is done in the Workshop without the Vehicle! Components are Exchanged and Vehicle Returns to Production within: 15 minutes for Wheels, Power-Modules & Cabins 25 minutes for Axle-Groups

5. Modular Design Modular Technical Design for all Truck Types Enables Fast Repairs Enables Container Transport Considerable Reduction of Spare Parts Stock More Economical Manufacturing Trucks can Continue Production even with a Technical Fault that could shut down a conventional truck for days! Engine shuts down: Truck still mobile! Flat tyre: Truck still mobile! Wheel-motor defect: Truck still mobile! Hydraulic defect: Truck still mobile! Trucks always able to return to the Workshop No blocking of Haul Roads, Loaders and Hoppers No Tow Truck Required

6. Modular Design Advantages Maintenance & Repair is completed in the workshop without the truck! Components are exchanged and truck returns to production within: 15 minutes for Wheels, Power-Modules & Cabins 25 minutes for Axle-Groups Considerable Reduction of Parts Stock for all Truck Types Identical Power-Modules Identical Axle-Groups

7. Major Components in Containers

8. Power-Module Changed in 15 minutes Unique Removable Power-Module designed for easy Exchange & Maintenance

9. Axle-Group Changed in 25 minutes

10. Fast Tire Changes in 15 minutes!

11. TRMS ©: Truck Repair Monitoring System All Employees Registrations via Fingerprint recognition All Individual Components/ Parts have RFID Tags / Barcodes For Electronic Data Processing Avoiding Human Error Integrated Preventive Maintenance Avoiding Unscheduled Repairs Technical Status of Components Permanently Monitored Global Trends in Operational Performance scrutinized by ETF Immediate Remedial Action taken if necessary Automatic Parts Ordering from European Stockholding Assures Delivery with Shortest Lead-times Automatic Warrantee Processing

12. In Case of Vehicle Fault: Message displayed to Operator & Workshop (in the local language!) When Convenient to the Operation (not when Hauling on grade, loading or unloading) truck returns to the workshop Informed Technicians are Ready with New Exchange Component Truck arrives at Workshop; Component is Exchanged Truck Back in full Production between 15 and 25 minutes later! Truck Back in full Production between 15 and 25 minutes later! Minimal Loss of Revenue! F-1 Pit-Stop System:

13. Automatic Tag Reading upon Entrance & Exit Workshop (Chassis, Power-Modules, Axle-Groups, Cabin, Dump-body & Tyres) Automatic Operating Hours Registration of Truck, Components & Tyres Reduces Maintenance and Inventory Costs Reduces Human Error

14. Maintenance & Repair Sequence: Stage 1: F-1 Pit-Stop System - Major Components Exchange - Enables 95% Technical Availability during Full Life Cycle Stage 2: Component Repair - Assures Components Availability Stage 3: Parts Repair - Reduces Costs

15. Stage 1: F-1 pit stop Flowchart: OPERATOR & WORKSHOP Alerted for Technical Fault by Truck Computer Technicians log in by Fingerprint and Prepare Exchange Component Manager assigns Technicians Truck, Components & Tyres Reading Truck Downtime Registration Truck Operating Hours Registration Job Data on Workshop Monitor Truck, Components & Tyres Reading Truck Downtime registration Truck Operating Hours registration Component Operating Hours registration Tyres Operating hours registration Component Repair Job assignment Job-Time registration Truck goes to workshop Automatic RFID Reading Upon Truck arrival in Workshop Prepared Component Exchanged Automatic RFID Reading Upon Truck exit from Workshop Truck returns to Operation Technicians log out
