Huhuu I have now also put in a nice GPZ550 ^^ Wants to carefully get to the bottom of the planer. Decomposed and recharged battery, does not seem to be deep discharge. Now I have looked for oil there is this bulleye, next to it stands 3L The short measuring rod is just so oily on the tip and in the bulleye you can see nothing, so nothing of the oil. Question 1.: If 3L were filled up how high should be to be seen in the bulleye about?? Question 2.: Could I have some oil first take what I only use for a short time?? Of course I could try it myself, which I will also do is only today Sunday and I would like to try for a short time if it will jump on, the oil I would then exchange next week for 10W-40 partlyynth. Thanks already for answers
