On the combination base plate On the machine VACUUM en PRC GFCI D VACUUM Upper: An additional means of securing the drill stand must be employed when the machine is used for horizontal drilling with the vacuum securing method. Lower: Use of the vacuum securing method for overhead drilling with the drill stand is not permissible. On the machine 208188 B/2.2004 Operate the system only with a properly functioning PRCD.
en To avoid injury, use only genuine Hilti core bits and DD 120 accessories. Observe the safety rules and operating instructions for the accessories used. Observe the information printed in the operating instructions concerning operation, care and maintenance. The machine, accessories and cutting tools may present hazards when handled incorrectly by untrained personnel or when used not as directed.

Technical data Right of technical changes reserved. NOTE The machine is available in various voltage ratings. Please refer to the machine’s type identification plate for details of its rated voltage and rated input power. Rated voltage [V] Rated power [W] Rated current [A] Mains frequency [Hz] Rated speed under no load, 1st gear [r.p.m.
Noise and vibration information (measured in accordance with EN 61029‑1) Typical A-weighted sound power level 102 dB (A) Typical A‑weighted sound pressure level 89 dB (A) Typical weighted vibration at the handwheel < 2.5 m/s² en 5. Safety rules 5.1 Basic information concerning safety a) CAUTION: The following basic safety instructions must be followed when using electric tools or machines to ensure protection against electric shock, risk of injury and fire hazards.
en the power tool for operations different from those intended could result in a hazardous situation. c) 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. d) Take the influences of the surrounding area into account. Do not expose the tool or machine to rain or snow and do not use it in damp or wet conditions.
at regular intervals and replace them if found to be damaged. c) Check the condition of the machine and its accessories. Do not operate the machine and its accessories if damage is found, if the machine is incomplete or if its controls cannot be operated faultlessly. d) Do not touch the supply cord or extension cord if it is damaged while working. Disconnect the supply cord plug from the power outlet. e) Damaged or faulty switches must be replaced at a Hilti service center.
6. Before use en CAUTION The mains voltage must comply with the specification given on the type identification plate. Ensure that the machine is disconnected from the electric supply. DANGER When drilling through walls, cover the area behind the wall, as material or the core may fall out on the other side of the wall. When drilling through ceilings, secure (cover) the area below as drilled material or the core may drop out and fall down.
4. Draw a line approximately 800 mm in length from the center of the hole to be drilled towards where the drill stand is to be positioned. 5. Make a mark on the line at a distance of 203 mm (8") from the center of the hole to be drilled. 6. Switch on the vacuum pump and press the vacuum release valve. 7. Bring the mark on the combination base plate into alignment with the line. 8.
BI+ chuck, only genuine Hilti core bits may be used with it. en CAUTION The core bit may become hot during use or during sharpening. There is a risk of burning your hands. Wear protective gloves when changing the core bit. CAUTION Disconnect the supply cord plug from the power outlet. NOTE C-Rod, A-Rod, M27, and BR chucks are operated with a 27 mm AF open-end wrench. 1. Use the carriage brake to lock the carriage in position on the rail and check that the system components are securely mounted. 2.
CAUTION The power tool and the drilling operation generate noise. Wear ear protectors. Exposure to noise can cause hearing loss. 7.2 Switching on and checking the ground fault circuit interrupter (PRCD) CAUTION Drilling may cause hazardous splintering. Splintering material presents a risk of injury to the eyes and body. Wear eye protection and a hard hat. 7.1.1 Unlocking the machine 1.
7.3 Drilling without use of the water collection system and industrial vacuum cleaner 7.4 Drilling with use of the water collection system (accessory) en WARNING Water must not be allowed to run over the motor and cover. WARNING Water must not be allowed to run over the motor and cover. WARNING Water drainage is uncontrolled. Overhead drilling is not permissible. CAUTION The water is drained through a hose. Overhead drilling is not permissible. 1.
7.5 Drilling with use of the water collection system and wet-type industrial vacuum cleaner (accessories) 8 7. Apply only light pressure until the diamond core bit has centered itself and then increase the pressure. 8. Regulate the contact pressure while observing the drilling performance indicator. (Optimum drilling performance is achieved when the drilling performance indicator shows a green light). 7.
8. Care and maintenance CAUTION Disconnect the supply cord plug from the power outlet. en 8.1 Care of core bits and metal parts Remove any dirt adhering to the surface of the core bits, the chuck and drive spindle and protect their surfaces from corrosion by rubbing them with an oily cloth from time to time. DANGER The machine may be operated, serviced and repaired only by trained, authorized personnel. This personnel must be particularly informed of any possible hazards.
9. Troubleshooting Fault Possible cause Remedy The machine doesn’t start. Interruption in the electric supply. Plug in another electric appliance and check whether it works. Check the plug connections, supply cords and extension cords, PRCD and electric supply. Replace the carbon brushes. See section: 8.4 Replacing carbon brushes 10 If necessary, the power tool should be repaired by Hilti Service.
en Fault Possible cause Remedy Drilling speed drops. The water flow rate is too low. The handwheel turns but doesn’t engage. Water escapes at the water swivel or gear housing. The retaining pin is broken. Adjust (open) the water flow regulator. Check the water supply. Fit a new retaining pin. The diamond core bit cannot be fitted into the chuck. Water escapes from the chuck during operation. The core bit connection end or chuck is dirty or damaged.
NOTE The disposal of drilling slurry directly into rivers, lakes or the sewerage system without suitable pretreatment presents environmental problems. Ask the local public authorities for information about current regulations. 1. Collect the drilling slurry (e.g. using a wet-type industrial vacuum cleaner) 2. Allow the drilling slurry to settle and dispose of the solid material at a construction waste disposal site (the addition of a flocculent may accelerate the separation process). 3.
