User help

1. Make sure it matches your machine. Look up your model and serial number and compare them with the coverage above. Not sure? Send us those details and we will help you check before you buy.
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 (Adobe Acrobat Reader, your browser, or a phone or tablet app). Save a copy to your computer and to a backup drive.
4. Jump straight to the section you need. Start from the table of contents or search for a part name, fault code or value, then print just those pages for the workshop.
5. Start with the symptom. Use the diagnostic and test procedures to isolate the fault first, then repair only what testing points to.
6. Safety first. Work on machinery, fuel and electrical systems carries real risk. Follow the document's safety notes, use suitable tools and supports, and comply with local rules. If a job is beyond your experience, use a qualified technician.
