EQUIPMENT AND APPLIANCES
When you close your extension on a rainy day, the water on top of the
extension box may leak into the interior of the trailer. This water should
be wiped up.
WARNING
Do not place anything on top of the extension box when it is closed,
to avoid causing damage when opening it.
The motorized extension mechanism has some sharp metal parts.
Never allow children to play underneath or around this module.
To ensure safe opening of your extension, check that there is adequate
space outside the trailer.
WARNING
As a safety measure, always disconnect the trailer's battery and 120-volt
connection to deactivate the mechanism before working on or under
the extension.
WARNING
Keep people, animals, and objects away from the motorized extension
box when operating the mechanism, which can pinch, or catch loose
clothing and cause injury.
