As this machine is basically the same as the older perform branded and the current Axminster AWVSL900 model
i would suggest talking to them would get you better results.
The rapid destruction of the belts sounds to me to be related to insufficient lubrication of the motor shaft/pulley interface and possibly the headstock pulley and mechanism.
Have a read of this thread, it might be of help. http://www.ukworkshop.co.uk/forums/post537049.html#p537049
if you can measure the pulley bore diameter then it may help Axminster in advising if they have suitable replacements.
In the first instance try contacting Richard Beer [Richard.Beer@axminster.co.uk] with your problem.
