Questions & Answers for Bosch 11203 (0611203034)

Why is it leaking a black like oil down the bit
Richard for model number 11203 asked on 2023-12-22
Hi Richard, Thank you for your question. If your rotary hammer is leaking oil, we would recommend checking the oil seals and o-rings. They may have become damaged or worn overtime and will need replacing. Check the seals and o-rings around the piston area and the gears. We hope this helps!
