Safety instructions
To ensure 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.
- Always wear safety helmet, goggles and ear protectors during drilling. Any local regulations that exist must also be observed.
- 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.
- Check that the hoses used are of the right quality, and that all hose connections are in good condition and properly tightened.
- Before starting work on any of the systems, make sure that the air and water systems are without pressure.
- Make sure that there are no concealed wires or other sources of electricity. Never drill near any electric wires or other sources of electricity.
Staring the rock drill
- Open the main valve for compressed air.
- Open the cock for the flushing water.
- Adjust the feed control lever to given a suitable feed force for collaring the hole.
- Align the rock drill so that the working tool touches the desired collaring point.
- Move the throttle lever forward a little, which will start water flushing, percussion and rotation.
- Collar the hole with reduced feed force.
- Move the throttle lever fully forward once the working tool has gained a secure footing in the rock.
- Adjust the feed force by means of the control lever so that the maximum penetration rate is obtained.
Note! Do not bend the working tool as this will increase wear of the shank bushing and piston. Furthermore, it can also affect drilling efficiency and increase the risk of working tool breakage.
Stopping the rock drill
Pull the throttle lever backwards, which will stop percussion, rotation and flushing water.
