much too heavy and high oil drain

The following drawbacks I find unacceptable:
The automatic oil supply dosed too high! The excess oil is in operation from dropwise and dirty the environment. Immediately after each use, the oil must be drained, and the chain and the entire chain section are de-oiled below the gray plastic cover from the excess oil. In addition, the saw a little oil loses permanently in rest periods. Without the measure described the storage location is abundant zugeölt. Even with the small vent hole in the oil tank screw cap comes from a lot of oil when the lid does not show up! With the 4.0 Ah battery (a small battery is meaningless, because quickly emptied) and the linkage of the complete assembly weighs 4.250 kg. The saw with her permanently mounted rod part weighs 2.025 kg. Since it is located at the end of a long pole, the weight makes due to the physical law of levers at the other end of the bar violently noticeable, even when the weights do not appear at first glance as high! The saw is so difficult to act that it is best used with two people. One grabs the rod center and carries the saw to the object and a second pack at the end of the bar and settled the Turning On / Off. Due to the lever principle, the handling of the rod center of course, is much easier. If a tackle alone at the bottom of the unit and lifts from the ground to the road, then that's really unreasonable difficult. The saw is so heavy that the rod in the horizontal position easily deflects. One extended with one or two nachgekauften middle parts, then the rod in this position is almost a U. So definitely you should leave it in the three-piece bar set.
Otherwise, it is both the saw and the battery to an excellent quality. The saw passes through each type of wood like butter.
Nevertheless due to the unacceptable disadvantages for me I forgive only 2 points and would not buy it again. Conclusion: Would I get the discount a slight Billigsäge with a 4.0 Ah battery, I would try it. Unfortunately, these saws are supplied with only weak-cost batteries that are empty after a few minutes.
