ALWAYS ENSURE THAT THE CARAVAN/TRAILER HANDBRAKE IS IN THE ON POSITION BEFORE ANY ATTEMPT IS MADE TO USE THE POWRACTAUTION SYSTEM. Before engaging the rollers to the tyres using the Powractuator system always ensure that are no obstructions (stones) etc that may prevent the rollers from travelling the required distance. In the event of a Powractuator motor failure it can be removed manually by rotating the 9 mm nut (covered by a rubber top hat shaped cover) anticlockwise. This can be done by hand but this will take some time, it is best to use a battery powered drill or screwdriver. |
