What is worth writing about
- A figure or a statement that is wrong: the most useful message we get.
- A standard or regulation that has been revised since the review date shown on a page.
- A question an owner has that this site does not answer.
- Permissions, licensing or republication.
What we cannot help with
We cannot diagnose a machine we cannot see, confirm that a specific part fits a specific
model, supply a figure from a manufacturer service document, quote or value equipment, or
recommend a repair shop. Those need either the machine in front of someone or documentation
we do not hold, and pretending otherwise would be exactly the failure this site is built
to avoid.
For anything about one particular machine, the manufacturer's own support line and a
dealer's service department both have documentation tied to your model and serial number.
That is a real advantage over any general reference, including this one.
There is no telephone number
We would rather say that plainly than publish a number nobody answers. There is also no
postal inquiry address, no live chat and no account system. This is a reference
publication, not a service business.
What to expect from a reply
A correction that names the page, quotes the disputed figure and supplies the relevant document gives the publication a concrete claim to check. The response can require comparing the model, revision and application before a change is justified. A message saying a page is wrong without saying which part takes considerably longer, because the first step is working out what was meant.
For an immediate product hazard use the manufacturer, recall and emergency channels; this form does not provide an emergency response.
