Safety instructions of pneumatic hand held rock drill:
To reduce the risk of serious injury or death to yourself or others, carefully read through this instruction booklet before putting the rock drill to use. Always follow the instructions given in this manual. h Always wear a safety helmet, impact resistant eye protection with side protection and ear protectors with CE mark during drilling. Any local regulations that exist must also be observed. h When drilling in certain minerals, there is a risk of spark generation. Before starting work, check that the machine is approved (in accordance with local regulations) for work under such conditions. h Always take great care when using the machine. The drill steel is subjected to heavy loading and can break, with a risk of injury to personnel. h Check that the hoses used are of the right quality, and that all hose connections are in good condition and properly tightened. h Before starting work on any of the systems, make sure that the air and water systems are un-pressurized. h Make sure that there are no concealed wires or other sources of electricity. Never drill near any electric wires or other sources of electricity. h Exposure to crystalline silica (sometimes called 'silica dust') as a result of drilling in rock may cause silicosis, cancer or death. To reduce silica exposure, use water flushing. h A compressed air hose that comes loose can lash around and cause personal injury or death. Check that the compressed air connections are not damaged and that they are properly attached.
Starting pneumatic hand held rock drill:
Open the main valve for compressed air.
2. Align the rock drill so that the drill steel touches the desired collaring point.
3. Move the throttle lever forward a little, which will start water flushing (if water is connected), percussion and rotation.
4. Collar the hole with reduced feed force.
5. Move the throttle lever fully forward once the drill steel has gained a secure footing in the rock.
Note! Do not bend the drill steel as this will increase wear of the shank bushing and piston. Furthermore, it can also affect drilling efficiency and increase the risk of drill steel breakage.
Stopping the rock drill Pull the throttle lever backwards, which will stop percussion, rotation and flushing water. Checking the lubrication The chuck and drill steel shank must always be covered by a film of oil.
