OIL IMMERSED ADVANTAGES

Oil immersed type diamond drilling machine is a kind of drill for the reinforced concrete, brick, stone, ceramic and refractory materials. It is suitable for equipment installation, installation of water and electricity, tunnels and other construction, installation. Oil immersed type diamond drilling machine gear oil has a very good pressure, when gear meshing friction surface temperature is high enough. The friction losses, greatly improving the service life of the gear. The bearing capacity of gear oil is high, is conducive to the tooth surface protection. At the high temperature it can guarantee the reliable lubrication of the gear. Viscosity temperature performance is good with the variation of working temperature, it ensures a sufficient liquidity at low temperature, ensure the liquid oil to the tooth surface and bearing friction loss, prevent injury. In the high temperature viscosity does not decrease too much, can form a lubricating oil sufficiently thick enough.

Attention: Our company does not assume any responsibility because the machine is not solid or fixed safety facilities are not in appropriate place cause accident.

SAFE OPERATION

1. Please read the manual carefully before operation. This machine may only be used by trained people.
2. Please check the voltage before start, the power voltage should be no more than ±5% of rated voltage. Higher voltages however can cause damages such as motor burning and electric leakage.
3. Wear helmet, insulating gloves, workwear. Do not wear wide clothing or jewellery, keep hair away from it in case of twist.
4. This machine is designed for wet drill bits, do not use other bits, and do not enlarge the motor load.
5. Pay attention that the water can't get into the motor, do not block the ventilation, in case of motor burning.
6. Check the workplace before operation, eliminate danger, such as high voltage power lines, gas piping water pipe and telecommunication facility and so on.
7. Pay attention to the safety of down layer if the machine should drill holes through floor. When drill on beam column, check the structure of building.
8. Do not work in explosive ambiances with the electric tool, in which there are flammable liquid, gases or dusts. Electric tools generate sparks which can inflame the dust or vapours.
9. Make sure, the drill machine starts to operate with no-load, starting with load is prohibited, or may cause damages to machine and users. Fix the machine well in case of dropping when working on high place.
10. Use high quality three-core cable and make sure the cable is connected with ground. A ground fault circuit interrupter is necessary.

OPERATION

1. The fixation of expansion bolt: Drill a hole by impact drill in the set position, screw the expansion bolt, make sure it is tight, fix the diamond drill machine on it, and adjust the four regulating screws to keep the drill machine from swinging.
2. The fixation of support rod: determine the drilling location, supporting rod, adjusting the length of the push rod, and adjust the fastening screws, so that the drilling rig substructure full contact face, and ensure the drill bit and drill vertical face, no swing.
3. Fix the drill bit, connect the power and water supply, move adjusting tools, switch on when the drill machine is no load, check the drill bit and sound, if everything is fine, then open the water tap, the machine can start to drill when water flow from the drill bit.
4. Take it slow when at first, when the drill bit cut in the wall, change to normal speed. Slow down when the drill machine run into steel.
5. Both mechanical and electronic protections exist in drill machine. When drilling, if the motor is working, while the drill bit is not moving, means the drill bit need sharpened or feeding speed is too fast, please pull out the drill bit then re-feed. If the motor stop when drilling, please return on the machine and slow down the feed speed.
6. After some time of use, the abrasion of friction plate may cause slip. Please take the clutch gear out of gearbox and change friction plates to unified size, tight the screws. Then put the gear back to gearbox (This step should be done by trained person).
