3 Safety Instructions

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.

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.
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.

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.

Electrical Connection

The DRS 162 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 connectthe 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.
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.

3.3 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 an 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.

4 Using the Drilling system

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
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 aroundthe machine (about 2 metres). This way, you can work safely and in case of operating troube you can intervene immediately.

4.1 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.

4.2 Surface interface

4.2.1 Dowel anchoring

The DRU162 drill rig can be securely attached to the surface with dowel anchoring.

Subsurface-specific anchoring elements must be used to secure the DRA162 drill rig. When positioning the dowels the installation instructions of the dowel manufacturer must be followed.

Example:

4.2.2 Vacuum fixing (optional)

The DRA162 drill rig can be securely attached to the surface with the appropriate TYROLIT Hydrostress components. 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 system. Movements during drilling cause hits of the drill bit against the drilling wall, what can lead to a breaking out of the segments. The drill bit can also cant in the bore hole, what causes damages on this.

4.3 Drilling

4.3.1 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.

4.3.2 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.

4.3.3 Overload Protection

In order to protect the operator, motor and drill bit, the DRA162 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.

4.3.4 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.

4.3.5 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!

4.3.6 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.

4.4 Care and Maintenance

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

4.4.1 Machine :

Repairs may be executed only by appropriately qualified and experienced personnel.
After every repair the machine has to be inspected by an electric specalist.
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 system 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 considerable 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.

4.4.2 Drill Rig

Always keep the drill rig clean, especially the column with the toothing and the 4 slidingpieces 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:

4.5 Environmental Protection

Raw material recycling instead of waste disposal
In order to avoid damages on transportation, the power tool has to be delivered in sturdy packing. The packing as well as the tool and its accessories are made of recyclable materials and can be disposed accordingly.
The tool’s plastic components are marked according to their material, which makes it possible to remove environmental friendly and differentiated because of available collection facilities.

Only for EU countries

Do not dispose of electric tools together with household waste material!
In observance of European Directive 2012/19/EU on waste electrical and electronic equipment and its implementation in accordance with national law, electric tools that have reached the end of their life must be collected separately and returned to an environmentally compatible recycling facility

4.6 Noise Emission / Vibration

The indication of noise emission is measured according to DIN 45 635, part 21. The level of acoustic pressure on the work place could exceed 85 dB (A); in this case protection measuresmust be taken.
Wear ear protectors!
The typical hand-arm vibration is below 2.5 m/s².
Measured values determined according to EN 60 745.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different applications, with different accessories or poorly maintained, the
vibration emission may differ. This may significantly increase the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or when it is running but not actually doing the job. This may significantly
reduce the exposure level over the total working period. Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the accessories, keep the hands warm, organisation of work patterns.

4.7 In Case of Malfunction

In case of breakdown, switch the motor off and disconnect it from the power.
Repairs of the electrical parts may only be performed by an authorised service specialist.
