Do me the oiler ordered my impact wrench to do this because I thought it would be money well spent. Alone filling through this small opening was only me with a syringe. When working with the impact wrench so much oil goes through, I refill the oiler already has after 4 wheels, absolutely impractical and is not suitable for machines with high Luftdurchsatz.Der grip of impact wrenches is totally contaminated with oil and smeared after a short time. At work is a clearly visible oil mist from the exhaust. Hab therefore the oiler entsorgt.Gebe any work few drops directly into the screwdriver doing it well.
