HON 512 with HON 650 pilot user manual
Illegible information on the device poses a risk of injury due to resulting
erroneous operation, use, or installation.
Labels, as well as inscriptions and stamping on the device, can eventually become soiled or
otherwise unrecognizable to such an extent that users will not be warned effectively of
hazards and may be unable to follow required operating instructions. This will pose a risk of
injury.
Make sure to always keep all relevant labels in good condition so that they will be easily
legible.
Immediately replace damaged and missing labels.
The following labels/markings can be found on the actuator assembly's casing:
