Too much tension on the belt can do this. Oiling the motor also causes it  
to attract dust. Dust works its way into the bushings and actually increases 
 friction. these things both cause increased amperage draw and can blow  
the fuses. Try loosening up the belt a bit. It should only have enough tension 
 to turn the flywheel such that when you grab the revolving flywheel, the 
belt  begins to slip on the motor pulley after only a bit of resistance.
 
Hope this helps.

Dear all
 
It's a bit late to bother Martin about this again, so maybe some of you  
can help. My M400 is blowing 2A fuses on its SMS - Martin tells me the motor  
probably needs oiling. I've done so in situ and replaced the  fuse, but no 
improvement. I'm keen not to remove the motor, as I'm a crap  mechanic and 
don't want the hassle of getting the drive belt back to its  correct tension, 
unless absolutely necessary.
 
Any ideas?
