If it is battery opperated try and get a replacement battery. If that dosent work try and find a new power cord for it because depending on how the power cord was when it was stroed if you straited it out of having it in storage for a while it might have broken a wire in the cord. If a new power cord dosent help try if possible oil the motor it is possible that over time it could have gotten a little mosture in it due to where it was stored. If any of these dont work you will sadly have to get drill.
