How flushing water reaches the hole
The flushing system supplies water to the hole to help remove drilling cuttings. The guide describes two arrangements: central supply through a rear inlet and water tube to the shank, and side supply through a front water sleeve into the shank's water inlet.
Water passages differ between rock drills. When looking for a water sleeve, tube or seal, identify the location and actual configuration first; parts from the two arrangements should not be assumed interchangeable.
Lubrication and dust protection
The guide describes oil mist being delivered to components including the rotation mechanism and front-head support sleeve for lubrication. Mist exiting the head also helps keep dust and contaminants out. Follow the equipment manufacturer's requirements for lubrication, oil supply and inspection intervals.
Prepare a parts request
Record the location of any water leak, wear or lubrication issue. Provide the drill nameplate, version, old part number and photos of connections and sealing surfaces. Check the water sleeve, seals or front guide components in the parts directory against the exact model.
