The oil is drained using the same point you fill it with.( eg. the dip stick)
You will have to tilt the mower to the side and the back so that the dip stick is pointing down and at the lowest point. With a container ready (min 1 litre) unscrew dip stick. The oil may take up to 5 minutes to drain so have a way of supporting the mower in this position before you start. NOTE: If you still have fuel in it you should drain that out as it can leak out of the carburator when you tilt the mower.
