Edward, to start the tractor in the cold, assuming it is cold in Norway now, you turn the key til the little coil on the dash lights up and you hold the key for 5-10 seconds to heat the glow plugs. Then turn the key the whole way to start the tractor, let it idle for a minute or two to let the engine/oils warm up a little. Longer wouldn't hurt either. Make sure the emergency brake is off by pushing the brake pedals to release the orange lever just below the steering wheel on your right.
Your gear lever on the left has L, M, H. L for very low speeds, (L=loader work), M for slightly faster (such as cutting the grass, m=mower), H for higher speed to get from one place to the other. Practice, practice, practice, go slow. It would take me forever to give you the whole manual (not in front of me just going by memory) but if you have specific questions on something go ahead and ask.
Are there any local dealers that you can contact to obtain a manual?
Love the front hitch, we don't have them in the states here, good looking tractor too. Stanley
