ORIGINAL OPERATING INSTRUCTIONS DD 500 - CA core drilling machine It is essential that the operating instructions are read before the machine is operated for the first time. Always keep these operating instructions together with the machine. Ensure that the operating instructions are with the machine when it is given to other persons.
1 General information 1.1 Safety notices and their meaning en Symbols DANGER Draws attention to imminent danger that will lead to serious bodily injury or fatality. WARNING Draws attention to a potentially dangerous situation that could lead to serious personal injury or fatality.
On the core drilling machine Lower: Use of the vacuum securing method for overhead drilling with the drill stand is not permissible. PD[ EDU & At temperatures below 4°C the cooling circuit must be drained as described before pauses of an hour or longer between use. On the vacuum base plate Location of identification data on the machine The type designation and serial number can be found on the type identification plate on the machine.
DANGER Use only the genuine Hilti accessories or ancillary equipment listed in the operating instructions. Use of accessories or ancillary equipment not listed in the operating instructions may present a risk of personal injury. 2.2 Use of the system with various items of equipment en Equipment Core bit diameter Drilling direction Standard working length With water collection system 82…250 mm (3.23… 9.84") 82…600 mm (3.23… 23.62") All directions 500 mm (19.69") All directions 500 mm (19.
2.5 Items supplied 1 1 Core drilling machine Operating instructions NOTE Accessories not supplied with the machine are available from your Hilti Center or can be ordered online at www.hilti.com. 2.6 Using a generator or transformer The core drilling machine may be powered by a generator or by way of site transformer when the following conditions are fulfilled: AC voltage, power output at least 10.000 VA The operating voltage must, at all times, be no more than 5% above or 10% below the rated voltage.
4 Safety instructions 4.1 General Power Tool Safety Warnings a) WARNING Read all safety warnings and instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or batteryoperated (cordless) power tool. en 4.1.1 Work area safety Keep work area clean and well lit.
ing. This helps to avoid tripping over the cord while working. 4.1.5 Service a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained. 4.2.1 General safety rules a) 4.2 Proper organization of the work area a) b) c) d) e) f) g) h) i) j) k) l) m) n) o) The machine may be operated only with a functional ground fault circuit interrupter (RCD residual current device).
en moval system. Drilling in materials hazardous to the health (e.g. asbestos) is not permissible. n) Dust from material such as paint containing lead, some wood species, minerals and metal may be harmful. Contact with or inhalation of the dust may cause allergic reactions and/or respiratory diseases to the operator or bystanders. Certain kinds of dust are classified as carcinogenic such as oak and beech dust especially in conjunction with additives for wood conditioning (chromate, wood preservative).
5 Preparation for core drilling WARNING While setting up the equipment, the core drilling machine must be disconnected from the electric supply. DANGER Check that the drill stand is securely fastened to the work surface. CAUTION The machine and the diamond core bit are heavy. There is a risk of pinching parts of the body. Wear a hard hat, protective gloves and safety boots. NOTE When carrying the drilling machine, use the carrying handle and the grip protrusion provided. 5.
1. 2. en 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. Turn the four leveling screws until they project approximately 5 mm beneath the vacuum base plate. Connect the vacuum connector on the vacuum base plate to the vacuum pump. Place the drill stand on the vacuum base plate. Fasten it securely using the screw and washer supplied. Locate the center point of the hole to be drilled. Beginning at the center point of the hole to be drilled, mark out a line with a length of approx.
4. 5. 6. 7. Push the eccentric pin into the carriage or the spacer as far as it will go. Use the hand wheel to tighten the eccentric pin moderately in a clockwise direction. NOTE The locking pin will shear if excessive force is applied. Pass the supply cord through the supply cord guide on the opposite side of the carriage. Check that the machine is mounted securely. 5.
6 The core drilling operation CAUTION The AC supply voltage must correspond to the voltage rating given on the type identification plate. en DANGER Have the earth / ground conductor installation in the mains supply and the earth / ground connection in the machine checked at regular intervals. WARNING Take care to ensure that the supply cord does not come into contact with rotating parts. WARNING Make sure that the supply cord is not pinched and damaged as the carriage advances.
Wet drilling using a water collection system and wet-type vacuum cleaner Dry drilling 6.4.1 Wet drilling without use of a water collection system 14 6.4.1.1 Starting the hole 1. 2. 3. 4. 5. 6. 7. 8. Switch on the water supply. Open the water flow regulator slowly until the desired water flow rate out of the core bit is achieved. WARNING The rotating core bit presents a risk of injury! A rotating core bit that is lowered toward the base material is capable of severing parts of the body.
WARNING The rotating core bit presents a risk of injury! A rotating core bit that is lowered toward the base material is capable of severing parts of the body. After fitting the core bit, adjust the system in order to reduce the distance between the core bit and the base material to a minimum before switching on the diamond coring machine. Bring the core bit as close as possible to the surface in which the hole is to be drilled. However, it should not touch the surface. 6.
8. Push the eccentric pin into the carriage as far as it will go. 6.9 Storage of the equipment and breaks between work at temperatures below freezing DANGER At temperatures below 4°C (39°F) the water in the cooling circuit must be blown out with compressed air when drilling is interrupted for more than on hour or before the equipment is stowed away. 1. 2. 3. 4. 5. Switch off the water supply. Disconnect the water supply hose from the core drilling machine. Open the water flow regulator.
en Fault Possible cause Remedy The machine doesn’t start and the temperature or over/undervoltage indicator blinks. The rate of drilling progress decreases. Fault in the electric supply. Switch the machine off and then on again. Check the electric supply (especially when a generator or transformer is used). Sharpen the diamond core bit on a sharpening plate with water flowing. The wrong type of core bit has been used. Seek advice from Hilti. Reduce the water flow rate by adjusting the flow regulator.
9 Disposal Most of the materials from which Hilti machines or appliances are manufactured can be recycled. The materials must be correctly separated before they can be recycled. In many countries, Hilti has already made arrangements for taking back old machines and appliances for recycling. Ask Hilti customer service or your Hilti representative for further information.
