BoSS X-Series Update Notification


In 2013 we became aware of a single and isolated incident where a BoSS® X3 Micro Powered Access Platform continued to operate after the user released the platform raise button on the hand-held controller. Following this incident we put in place a communications campaign with a remedial plan to check and upgrade all affected machines.

The solenoid valve upgrade kits, together with fitting instructions were sent to all who had purchased machines manufactured before November 2012, who responded to the communication.

On 27th October 2016, we were notified of a second incident affecting one of the machines within this same batch of serial numbers, which unfortunately was not upgraded. If your company purchased machines within this period, we request you to re-check that all machines were upgraded as per our initial request.

Please check your BoSS® X-Series micro powered access machine

If you have any machines that are affected by this notice that have not been upgraded then please contact us immediately. Only those machines within this batch are affected by this issue.
