Hi,
Just got, believe me or not, Michel answer. Going' to follow this manual and then return back.
Copypaste from my mailbox:
Good Morning Mikhail,
Thanks for your e.mail.
To start, you can place a small amount of oil onto the motor spindle but it needs to be applied from the bottom of the motor. Remove the cap screw from the motor top plate, lift the motor, you will need to push the motor lead back into the motor tube to create some slack and then apply a few drops of light oil to the underside of the motor.
Regards
Steve Rowland.
