Manufacturer support numbers

Every number here was read off the manufacturer’s own website and is shown with its source and the date it was checked.

Try your distributor first

For most manufacturers the local distributor is the real technical support line — they hold the fault history, the parts and the authority to make a warranty call. The corporate numbers below are the fallback when the distributor cannot help, and several of them are consumer lines that will route you to a dealer rather than an engineer.
