User help

1. Check the fit first. Compare your machine's serial number against the configuration or prefix shown above before you order. If you're not sure it matches, send us your serial number and we'll help you confirm.
2. Get the file. This is a digital PDF download. Nothing is shipped, so you can start using it as soon as you have the file.
3. Open it anywhere. Use any current PDF reader on a computer, tablet or phone, and keep a backup copy.
4. Find things quickly. Use the contents pages and your reader's search (Ctrl+F or Cmd+F) to jump to a component or procedure, and print only the pages you need for the workshop.
5. Work step by step. Follow the stated torque values and disassembly/assembly sequence, and use the specification and testing sections to confirm a fault before replacing parts.
6. Stay safe. Work on engines, hydraulics, fuel and electrical systems carries real risk. Follow the safety instructions in the document, use proper tools and support equipment, and follow local regulations.
