Maintenance

 

Maintenance is essential to keep your caravan in a safe and usable condition. Caravans are no different to any other 

motor vehicle and require servicing at regular intervals which may vary according to use and the environment in which it 

is used. The service schedule outlines the service intervals for safe travelling and your owner obligations under our 

warranty policy. Servicing should always be carried out by a competent person with relevant experience.  
WARNING: 

Never work beneath the caravan while suspended on a jack. Always use “Jack Stands” with an adequate SWL.

Always use dedicated jacking points

240volt appliances and wiring must only be serviced and repaired by a qualified tradesperson.

Gas plumbing must only be serviced and repaired by a qualified gas fitter
