Safety Instructions

1. Safe work with the machine is only possible, if you read these operating instructions completely and strictly follow the instructions contained herein.
   In addition, the general safety instructions in the enclosed brochure have to be observed. Take part in a practical introduction before the first use. Save all warnings and instructions for future reference.

2. If the connection cable is getting damaged or cut during the work, don’t touch it, but instantly pull the plug out of the socket. Never use the machine with damaged connection cable.

3. When drilling in ceilings or walls make sure you will not cut through electrical mains, gas or water pipes. Use metal detection systems if needed.
   Before you start working, consult a statics specialist to determine the exact drilling position.
   If drilling through ceilings, secure the place below, because the core may drop out.

4. Pay attention that the tool is not exposed to direct rain.

• Do not use the tool in an environment with danger of explosion.

• Do not use the tool standing on a ladder.

• Do not drill in asbestos-containing materials.

• Never carry the tool at its cable and always check the tool, cable and plug before use. Have damages only repaired by specialists. Only insert the plug into the socket when the tool switch is OFF.

• Modifications of the tool are prohibited.

• The machine should only run under supervision of. Pull the plug and switch the machine off if it is not under supervision, e.g. in case of setting up and stripping down the machine, in case of voltage drop or when fixing or mounting an accessory.

• Switch the machine off if it stops for whatever reason. This way, you avoid that it starts suddenly and not under supervision.

• Do not use the machine if a part of the housing is damaged or in case of damages on the switch, the connecting cable or plug.

• Power tools have to be inspected visually by a specialist in regular intervals.

• Always lead the cable to the back, away from the machine.

• When using the drill, cooling water is never allowed to get into the motor and electrical parts.

• Overhead-drillings only with suitable safety measures (water collection).

• After an interruption of your work, only switch the machine on again after having checked that the drill bit can be turned freely.

• The tool may be used with the drill rig only.

• Do not touch rotating parts.

• Persons under 16 years of age are not allowed to use the tool.

• During use, the user and other persons standing nearby have to wear suitable ear protectors, goggles, helmets, protective gloves and boots.
  

• Always work concentrated and carefully. Do not use the tool when you are lacking in concentration.
  For further safety instructions, please refer to the enclosure!

Electrical Connection

The DB 201 is made in protection class I. For protection purposes the machine can only be run with a GFCI. For this reason, the machine is standard equipped with a PRCD switch integrated in the cord which allows to connect the unit directly with a grounded socket.

Attention!

• The PRCD-protective switch must not lay in water.
• PRCD-protective switches must not be used to switch the tool on and off.
• Before you start working, check the proper functioning by pressing the TEST button.

When connecting to a household current network protected with 16 A, we recommend the use of a starting current limiter as intermediate plug.
Only use 3-wire extension cable with protecting conductor and a sufficient cross-section (min. 2.5 mm2). A cross-section which is too small could lead to an excessive power loss and to overheating of machine and cable.
First, check the correspondence of voltage and frequency and compare it with the data mentioned on the identification plate. Voltage differences from +6 % to -10 % are allowed.

Water Supply

If the drill bit is not cooled enough with water, the diamond segments could heat up and consequently get damaged and weakened. For this reason, always make sure that the cooling system is not blocked.
In order to supply the machine with water, please proceed as follows:

• Connect the tool to the water supply system or a water pressure vessel by means of the GARDENA connector.
• Always make sure that the machine only runs with enough clear water as the seals get damaged when the machine is running dry.
• Attention! The maximum water pressure should not exceed 3 bar.
• Make sure that the segments are well cooled. If the drilling water is clear, the segments are well cooled.
• Overhead-drilling only with water collection ring.
• In case of frost warning, drain the water system.

Drill Bit Change

Attention!
When you use or sharpen the machine, it might heat up enormously.
You could burn your hands or get cut or ripped by the segments.
Always disconnect the plug from the mains before the beginning of any work on the tool. Always use protective gloves when changing the drill bit.
The drill spindle has a right-hand thread.
To counterhold on spindle always use a jaw wrench SW 32.
Never remove the drill bit with impacts, otherwise it could get damaged.
With some waterproof grease, which is put on the drill bit thread between spindle and drill bit, and a copper ring between spindle and drill bit you can remove the drill bit easier.

Using the Drilling Unit

In order to operate safely, please observe the following instructions:
Safety at work

• Make sure that your work place is free of anything that might disturb your work.
• Pay attention that your work place is well-lit.
• Make sure that you observe the conditions for the connection with the power supply.
• When laying the cables, make sure that it cannot be damaged by the tool.
• Make sure that you always can overlook the work place in a sufficient way and that you always can reach all necessary control elements and safety devices.
• In order to avoid accidents, keep other persons away from your work place.

Required space for operation and maintenance
If possible, make sure that you have enough free space for operation and maintenance around the machine (about 2 metres). This way, you can work safely and in case of operating trouble you can intervene immediately.

Preparation

• When you drill into blocs, make sure that the blocs are well anchored and fixed.
• Before drilling in supporting parts, make sure that you do not disregard the statics. Observe the instructions of the experts who are responsible for the design.
• Make sure that you do not damage any gas mains, water mains or electric cables while drilling.
• Pay attention that you do not touch any metallic parts of the machine when you drill walls and grounds and electric cables could lie under water.
• Pay attention that the drilling core does not hurt anybody or damage anything when it drops out. Please clear and clean your work place.
• If the drilling core might cause any damage when it drops out, use an appropriate device that can hold back the drilling core.
• Make sure that the drill bit is well fixed.
• Only use tools which are suitable for the particular material.

Fastening of the Drill Rig

Fastening by means of dowels in concrete

For brickwork, dowels for brickwork must be used.

• Mark the position of the drill holes for the fastening on the surface to be drilled.

• Drill a hole (Ø 16) 50 mm deep (A), into which the dowel M12 (B) is to be placed; insert and secure the dowel with the doweling tool (C).

• Screw the quick action clamping screw (D) into the dowel.

• Install the drill rig.

• Fix the washer (E) and finally the fastening nut (F) on the quick action clamping screw (D).

• Tighten the fastening nut (F) with a wrench SW 27.

• Before and after tightening the nut (F), the 4 adjustable screws have to be adjusted in order to adapt the rig to the surface.
  Do check whether the drill rig is installed safely and firmly.

Fastening by means of quick action bracing unit
In order to brace the drill rig by means of the quick action bracing unit, the distance to the opposite wall must be between 1.7 m and 3 m.

Position the drill rig. Place the quick action bracing unit as close as possible behind the column on the base of the rig. Fix the drill rig by turning the crank (G) clockwise.
Secure the position by means of the appropriate bolt (H).

Fixing on the floor by means of vacuum
Do not use the vacuum fastening on the wall or overhead!
Vacuum fixing may only be used if the area to be drilled is level, free of pinholes and cracks, otherwise this method cannot be applied.
For the vacuum fixing you need the vacuum pump, plate and the vacuum tube (see picture). These are available on request.

Connect the drill rig and the vacuum pump by means of the vacuum tube.
Bring the drill rig into the correct position and switch the pump on.
Check whether the four levelling screws in the base plate are completely turned back and a vacuum of -0.8 bar minimum is achieved.
The vacuum pump has to run during the complete operation, it is to be placed in such a position that you can monitor the pressure gauge at all times.

Attention! It is important that the drill rig is tightly connected with the ground. Incorrectly fixed drill rigs can cause injuries of the operator and damages on the drilling unit. Movements during drilling cause hits of the drill bit against the drilling wall, which can lead to a breaking out of the segments. The drill bit can also tilt in the bore hole, which causes damages on this.

Drilling

Vertical drilling

• Switch the PRCD on.
• Open the water supply.
• Turn the motor on without touching the surface with the drill bit.
•  Turn the handle to lower the drill bit until it touches the surface.
• In order to reach an exact centring of the drill bit, keep the feed low for the first centimeter of cutting depth.
• Then you can drill faster. A drilling speed which is too low reduces the power. On the other hand, when the drilling speed is too high, the diamond segments quickly become blunt.

You have hit reinforced iron when you recognise while drilling that the feed rate gets very low, when you need to use more force, or when the water
leaking from the bore hole clearly shows some metal chips.
Reduce the pressure on the drill bit to cut through the reinforced iron without any problems. You can increase the pressure again when you have cut through the reinforced iron.

Drill bit extension
When you need to drill deeper than the usable length of your drill bit is:

• First, only drill to the point the usable length of the bit reaches.
• Remove the bit and pull the centre core out of the hole without moving the core drilling unit.
• Push the drill bit back into the bore hole.

Screw an adequate extension between drill bit and motor. If the collet of the drill bit is 1 ¼” , please do not forget the copper rings which make the removal of the drill bit easier.

Drill Bits

Always use drill bits which match the material which has to be drilled.
You can prevent the machine from damage if you only use drill bits which are balanced and not deformed. Pay attention that diamond segments have enough relief cut towards the drill bit body.

Overload Protection

In order to protect the operator, motor and drill bit, the DB 201 is equipped with a mechanical and electronic overload protection.

Mechanical: If the drill bit is suddenly blocked in the hole, a clutch will slip disengaging the drill spindle from the motor.
Electronic: In case of overload due to too large feed force, the motor cuts off automatically. After discharge, switching OFF and ON again, drilling can be continued.

Safety Clutch

The safety clutch should absorb shock and excessive stress.
To keep it in good condition, the clutch should slip for a very short time (max. 2 seconds) in each case only. After excessive wearing the clutch has to be renewed by an authorized service shop.

Fracture of Segment

If a diamond segment, parts of the armouring or something simliar break out while drilling, and consequently the drill bit seizes, stop working on this bore and drill a hole having the same centre and a diameter being 15-20 mm bigger.

Do not try to finish your work using another drill bit of the same diameter!

After Drilling

When you have finished drilling:

• Pull the drill bit out of the hole.
• Stop the motor by using the motor switch and not the PRCD switch.
• Close the water supply.

Removal of the core when it sticks in the drill bit:

• Separate the drill bit from the motor.
• Put the drill bit in a vertical position.
• Knock carefully on the pipe by using a wooden hammer shank till the drilling core slips out. Never throw the drill bit against a wall by force or set about it with tools, such as hammer or jaw wrench.
  Otherwise, the pipe could go out of shape and neither the drilling core can be extracted nor the drill bit is reused.

Removal of the core from blind holes:
Break off the core with a cotter or lever, or in pieces. Lift the core out with appropriate tongs or drill a hole in the core, screw an eyebolt in and pull the core out.

Care and Maintenance

Before the beginning of the maintenance or repair works you have to disconnect the plug from the mains!

Machine:
Repairs may be executed only by appropriately qualified and experienced personnel. After every repair the machine has to be inspected by an electric specialist. Due to its design, the machine needs a minimum of care and maintenance. Regularly the following works have to be carried out or rather the component parts have to be inspected:

• Clean the drilling unit after you have finished drilling.
  Then grease the thread of the drill spindle.
  The ventilation slots always have to be clean and open.
  Pay attention that no water gets into the machine during the cleaning process.

• After the first 150 hours of operation you have to change the gearbox oil.
  Gearbox oil changes cause a considerably longer lifetime of the gearbox.

• After approx. 200 hours of operation the carbon brushes have to be checked by an electric specialist and if necessary removed them (use original carbon brushes only).

• Have switch, cable and plug checked by an electric specialist quarterly.

Drill Rig:

• Always keep the drill rig clean, especially the column with the toothing and the 4 sliding pieces in the mounting plate. In order to allow the free movement of the pinion shaft it should be slightly lubricated.
• In order to achieve a good performance of the drill rig, the 4 sliding pieces in the machine holder have to move along the column without backlash.

If the position has changed, it can be readjusted as follows:

• Loosen the counter nut on the Allen screw by means of a jaw wrench SW17
• Adjust the Allen screws and the position of the thrust piece to the column by means of a hex head wrench.
• Tighten the counter nut again and check whether the carriage moves easily on the column.
