Original Cheyenne Hawk - loss of power

[julianforrester]

any ideas ?
a couple of weeks ago i put some light oil on the bearing not realizing its self lubricating.
i noticed a few days later that when holding the machne 'normally' it would loose power and increasing voltage wouldnt adjust the power to a point where it cut out at 12.5v (protective circuit)
if i held the machine upside down it suddenly picks up power and operates normally.
i stripped the machine and noted oil had migrated down to the back of the motor and onto the PCB. i dried it as best as i could, used a hairdryer on it too, rebuilt and tested - same thing !
i stripped it again only to break the fekking wires off the PCB to the jack !!!
a mate who is an electrical engineer took the machine to his lab where he re-attached the wires, not before removing the PCB from the motor and noting oil was on the back of the board, he dried it and rebuilt.
when i got it back it worked great for 2 days, now im seeing the same power limited issue ???? again it picks up fine upside down...
i really love this machine and im gutted that im getting this issue, any help/suggestions would be appreciated

Oil may be in the motor.

I didnt see anywhere in the manual where is requires oil. It has a two year warranty, id try to get rid of any and all evidence of oiling the machine n send it back to your supplier and they should replace any faulty parts. You may have to pay for the motor for oil in it. But you will have a working hawk again.
