2 General safety instructions for power tools

WARNING

Read all safety instructions and precautions marked with the symbol.

Failure to observe the safety instructions and precautions can result in electric shock, fire and / or serious injuries.

Keep all safety instructions and precautions for future reference.

The term “power tool” used in the safety instructions refers to mains-operated power tools (with mains power lead) and battery-operated power tools (without mains power cable).

2.1 Workplace safety

a) Keep your work area clean and well illuminated.
Untidiness and unlit work areas can result in accidents.
b) Never use the power tool in potentially explosive environments containing flammable liquids, gases or dusts.
Power tools generate sparks which can ignite dust or vapours.
c) Keep children and other persons away from the power tool during use.
A moment's distraction can cause you to lose control of the machine.

2.2 Electrical safety

a) The connecting plug of the power tool must fit in the plug socket. The plug must not be modified in any way. Do not use adapter plugs in conjunction with power tools with protective earth conductor.
Unmodified plugs and properly fitting plug sockets reduce the risk of electric shock.
b) Avoid physical contact with earthed surfaces such as pipes, heaters, cookers and refrigerators.
There is an increased risk of an electric shock if your body is earthed.
c) Keep power tools away from rain and moisture.
The ingress of water into a power tool increases the risk of an electric shock.
d) Do misuse the cable in any way by using it to carry or hang up the power tool or to pull the plug out of the socket. Keep the cable away from heat, oil, sharp edges and moving machine parts.
Damaged or kinked cables increase the risk of an electric shock.
e) When working with a power tool outdoors, use only extension leads that are suitable for outdoor use.
Use of an extension lead suitable for outdoor use reduces the risk of electric shock.
f) If the use of the power tool in a damp environment is unavoidable, use a residual-current circuit breaker.
Use of a residual-current circuit breaker (RCCB with 10 mA maximum tripping current) reduces the risk of an electric shock.

2.3 Safety of people

a) Always work carefully, attentively and sensibly when using a power tool. Do not use the power tools if you are tired or are under the influence of drugs, alcohol or medication.

A moment of inattention while using the power tool can result in serious injuries.

b) Wear personal protective equipment and always wear goggles.

The wearing of personal protective equipment, such as dust mask, non-slip safety shoes, helmet or ear protectors, depending on the type and application of the power tools, reduces the risk of injuries.

c) Avoid accidental switching on of the power tool. Ensure that the power tool is switched off before connecting it to the mains power supply and/or connecting the battery and before picking up or carrying the tool.

If you have your finger on the switch when carrying the power tool or you connect the tool to the power supply when it is switched on, this can lead to accidents.

d) Remove the adjusting tools or wrenches before switching on the power tool.

A tool or wrench in a rotating part of the tool can result in injuries.

e) Avoid abnormal postures when working. Ensure you are standing firmly and maintain your balance at all times.

This will enable you to control the power tool better in unexpected situations.

f) Wear suitable clothing. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts.

Loose clothing, jewellery and long hair can get caught in moving parts.

g) If dust extractor and collection equipment can be mounted, they must be connected and used correctly.

Use of a dust extraction system can reduce the hazards caused by dust.

h) Don't be lulled into a false sense of safety and do not break the safety rules for power tools even if, after much use, you are familiar with the power tool.

Careless action can cause severe injuries within fractions of a second.

2.4 Using and handling the power tool

a) Do not overload the power tool. Use the intended power tool for your work. You work better and safer within the given power range if you use the suitable power tool.

b) Do not use a power tool whose switch is defective.

A power tool which can no longer be switched on or off is dangerous and must be repaired.

c) Remove the plug from the plug socket and/or remove the battery before carrying out tool adjustments, changing accessories or placing the tool aside.

This precautionary measure prevents unintentional starting of the power tool.

d) Store power tools out of the reach of children when not in use. Do not allow people to use the power tool if they are not familiar with it or if they have not read this instruction manual.

Power tools are dangerous if they are used by inexperienced people.

e) Maintain power tools with care. Check whether moving parts are in proper working order and do not jam, whether parts are broken or damaged in such a way that they impair the function of the power tool. Have damaged parts repaired before using the tool.

Many accidents are caused by poorly serviced and maintained power tools.

f) Keep cutting tools sharp and clean at all times.

Carefully maintained cutting tools with sharp cutting edges jam less easily and are easier to control.

g) Use the power tool, insert tools, etc. in accordance with this instruction manual.

Take into consideration the working conditions and the work to be carried out. Use of power tools for other than the intended applications can lead to dangerous situations.

h) Keep the handles and gripping surfaces dry, clean and free from oil and grease.

Slippery handles and gripping surfaces prevent safe operation and control of the power tool in unforeseen situations.

2.5 Service

a) Have your power tool repaired by qualified personnel only and use original spare parts only.

This will ensure that the safety of the power tool is maintained.

2.6 Safety instructions for wet diamond drills

2.6.1 Operating personnel requirements

• People below the age of 18 may not use the machine.

- The operating personnel must be familiar with the content of this instruction manual.

2.6.2 Safety instructions for all work

- Wear hearing protection when hammer drilling / diamond drilling.

Exposure to noise can cause loss of hearing.

• Use the additional handle(s).

Loss of control can result in injuries.

• Support the power tool properly before using.

This power tool produces a large torque. If the power tool is not properly supported during use, the use can loose control of it and injuries can occur.

2.6.3 Workplace safety

- Secure the work area also behind openings and cutouts.

Unsecured work areas can endanger you and other people.

- Watch out for open and concealed electricity cables, and water and gas pipes. Use suitable detectors to find concealed utility pipes and cables, or contact the local utility company for advice.

Contact with electricity cables can cause fires and an electric shock. Damage to a gas pipe can cause an explosion. Penetrating a water pipe causes damage to property or could cause an electric shock.

- Do not use the power tool near flammable materials.

Sparks could ignite these materials.

- Avoid causing situations where other people can stumble or trip.

Tripping over cables can cause serious injuries.

- Secure the workpiece.

A workpiece securely held in clamping devices or a vice is more safely held than in the hand.

- Avoid dust accumulation in the workplace.

Dusts can easily ignite.

- Ensure adequate ventilation in closed rooms.

Risk due to dust and impaired vision.

- When carrying out drilling work that requires the use of water, route the water away from the work area or use a liquid collection device.

Such precautions keep the work area dry and reduce the risk of an electric shock.

EN

• Inform and consult the responsible structural engineer, architect or the responsible site engineer about planned drilling.
  Cut through reinforcement only with the approval of a structural engineer.
• When drilling through walls and ceilings, ensure that people and work areas on the other side are protected.
  The core drill bit can extend beyond the drill hole and the drilled core can fall out on the other side.
• Before drilling holes drilling objects, check the rooms concerned for obstructions and block off this area. Use formwork to secure the drill core against falling.
• Dust from materials such as coatings containing lead, several types of wood, minerals and metals can be harmful to health and cause allergic reactions, respiratory diseases and/or cancer.
  Asbestos-containing material may only be machined by specialists.
  ▶ Where possible use dust extraction suitable for the material.
  ▶ Ensure the workplace is properly ventilated.
  ▶ We recommend wearing a face mask respirator with filter class P2 or P3 (to EN 149:2001).
  Observe the relevant regulations in your country for the materials to be machined.

2.6.4 Electrical safety

• The power tool may only be used for wet drilling if operated with a perfectly functioning PRCD personal protection switch (see page 41).
• Before each use, check the power tool, connection cable and plug for damage.
  Damaged equipment is dangerous, and no longer safe to use.
• Note the mains voltage! The power source voltage must match the details given on the rating plate of the power tool.
• If using the power tool with mobile generators, loss of power or atypical behaviour on switching on is possible.

• Do not use the power tool if the cable is damaged. Do not touch the damaged cable and disconnect the mains plug if the cable is damaged while you are working.
  Damaged cables increase the risk of an electric shock.

• Only use extension cables suitable for the machine's power consumption and which have a minimum core cross-section of 1.5 mm ^2 . If you use a cable drum, always completely unwind the cable.
  The rolled up cable can heat up and start to burn.

• Regularly clean the ventilation slots of your power tool by blowing it out. Never use liquids. Never insert screwdrivers or any other objects into the ventilation slits. Do not cover the ventilation slits.
  The motor fan draws dust into the housing and a large accumulation of metal dust can cause electrical hazards.
• External electromagnetic interference (e.g. mains voltage fluctuations, electrostatic discharges) can cause the power tool to switch off automatically.
  In this case, switch off the power tool and then switch it back on again.
• Before use, check all water-carrying parts – including those of the accessories – for perfect working order and leaks.
  Leaking water increases the risk of an electric shock.

2.6.5 Safety of people

- Wear personal protective equipment and, depending on the work situation, use:

Full-face protection, eye protection or safety glasses/goggles, hard hat and special apron

Protect yourself against debris thrown up by wearing a hard hat, safety goggles or face protection and wear an apron, if necessary.

Hearing protection

The typical A-weighted sound pressure level of this power tool is over 85 dB (A) while working with the tool. If you are exposed to loud noise for lengthy periods, there is a risk of hearing damage or even hearing loss.

Anti-vibration safety glove

At a release value A (8) for arm-hand vibrations of over 2.5 m/s ^2 , the wearing of anti-vibration safety gloves is recommended.

Non-slip safety footwear

Dust mask, half-face filter mask or face mask respirator

Inhaling fine mineral dust can cause health damage. We recommend wearing a face mask respirator with filter class P2 or P3 (to EN 149:2001).

Wet drilling: Working with wet diamond core drill bits is a grinding process, during which extremely fine dust is produced, which is bound by the added water. If the used water with the bound dust is not collected, the bound dust is re-released after drying. When drilling materials containing quartz, the risk of silicosis is very high; therefore, the machine may only be used in wet mode.

- Ensure other people keep a safe distance from your work area. Any person entering the work area must be wearing personal protective equipment.

Broken pieces of the workpiece or broken insert tools can fly off and cause injuries, even outside the immediate work area.

- Operate the power tool by holding the insulated gripping surfaces when carrying out work during which the cutting tool can hit concealed electrical cables or the tool's own power lead.

Contact of a cutting tool with a live cable can also energise metallic parts of the power tool and result in an electric shock.

- Keep the mains power lead away from rotating insert tools.

If you lose control of the tool, the mains power lead can be cut or caught and your hand or arm can be pulled into the rotating insert tool.

- Never put down the power tool until the insert tool has come to a complete standstill.

The rotating insert tool can come into contact with the surface on which the power tool is placed, which could cause you to lose control of the power tool.

- Do not leave the power tool running while you are carrying it.

Your clothing can get caught by inadvertent contact with the rotating insert tool and the insert tool can drill into your body.

- If the machine is switched on, do not direct insert tools towards your own or other people's bodies. Do not touch or take hold of the tools.

• Always use the additional handle supplied with the tool.

Loss of control of the machine can result in injuries.

- Do not use this tool for overhead drilling with water supply.

The ingress of water into the power tool increases the risk of an electric shock.

2.6.6 Hazards when using and handling the power tool

- If the machine is used for hand-held drilling, always hold both handles firmly when switching on and while working with the machine. When switching on and while working with the machine, expect reaction torques (e.g. due to sudden jamming or breakage of the insert tool).

- If the insert tool becomes blocked, stop exerting feed and switch off the tool. Check the reason for the jamming and remove the cause of jammed insert tools.

- If you want to restart a diamond drill, which is in the workpiece, before switching on, check whether the insert tool rotates freely. If the insert tool jams, it possibly does not rotate and this can cause overloading of the tool, or can cause the diamond drill to detach itself from the workpiece.

- Do not use any accessories, which have not been especially provided and recommended for this power tool by the manufacturer. Just because you can attach the accessories to your power tool is not a guarantee of safe use.

- The approved speed of the insert tool must be at least as high as the maximum speed given on the power tool.

Accessories which rotate faster than approved can break and fly off the tool.

- Change insert tools carefully and only use the mounting tools provided, if they are in perfect condition. Disconnect the mains plug before changing the insert tool.

Use of the mounting tool provided prevents damage to the power tool and insert tool.

- Never use damaged insert tools. Before each use, check insert tools for splinters and cracks. If the power tool or insert tool is dropped or falls, check whether it is damaged, or use an undamaged insert tool. If you have checked and inserted the insert tool, keep yourself and other people nearby outside the plane of the rotating insert tool and let the power tool run at maximum speed for one minute.

Most damaged insert tools break during this test period.

- Do not expose power tools to extreme heat or cold.

Mechanical and electrical damage can occur during extreme heat and/or cold.

- Allow the insert tools, tool holders and other parts cool in the immediate vicinity of the work area after use.

The equipment can be very hot after use. Do not touch or grip the parts. Risk of injury.

- Additional signs or other, non BAIER-specific parts may not be screwed or riveted onto the motor, handle, gearbox or protective housing.

This could damage the power tool and cause malfunctions to occur.

- When fixing the drill stand on the workpiece using anchors and screws, ensure that the anchoring used is able to hold the machine safely during use.

If the workpiece is not resistant or is porous, the anchor can be pulled out, which causes the drill stand to detach from the workpiece.

- If fixing the drill stand on the workpiece by means of a vacuum plate, ensure that the surface is smooth, clean and not porous.

Do not fix the drill stand onto laminated surfaces, such as tiles and facings of composite materials.

If the surface of the workpiece is not smooth, flat or adequately fixed, the vacuum plate can detach from the workpiece.

- Before and while drilling, ensure that the vacuum is sufficient.

If the vacuum is insufficient, the vacuum plate can detach from the workpiece.

- Never carry out overhead drilling and drilling in the wall, if the machine is only fixed by means of a vacuum plate.

In the event of loss of vacuum, the vacuum plate detaches from the workpiece.

- Avoid unnecessary noise emissions.

• Note and follow the safety and work instructions for the accessories used.

2.6.7 Safety instructions for using long drill bits

- Never work with a higher speed than the maximum allowable speed of the drill bit. At higher speeds the drill bit can bend easily, if it can twist itself free without contact with the workpiece and result in injuries.

- Always start drilling at a low speed and while the drill has contact with the workpiece.

At higher speeds the drill bit can bend easily, if it can twist itself free without contact with the workpiece and result in injuries.

- Do not exert excessive pressure and only press in the longitudinal direction of the drill bit.

Drill bits can bend and therefore break or result in a loss of control and injuries.

2.6.8 Hazards when using and handling the drill stand

- Before mounting the drill or drive unit, set up the drill stand correctly in accordance with these instructions. Correct assembly is important to ensure proper, faultless functioning of the stand.

- Fasten the drill stand securely on a firm, flat surface using the specified and undamaged installation materials.

If the drill stand can slip or wobble, the drill or drive unit cannot be guided uniformly and safely.

- Disconnect the plug of the drill or drive unit from the socket before mounting the drill or drive unit on the drill stand, make any unit settings or change accessory parts.

Unintentional starting of drills or drive units causes accidents.

- Fix the drill or drive unit securely onto the drill stand as specified before starting work. Slipping of the drill or drive unit on the drill stand can cause loss of control and injuries.

- Remove all setting tools, spanners and installation materials not required before switching on the drill or drive unit.

Setting tools, spanners and installation materials located in/on a rotating part of the unit can result in injuries.

- Do not overload the drill stand and do not use it as a ladder or scaffolding.

Overloading or standing on the drill stand can cause the centre of gravity of the drill stand to move upwards and the drill stand overturns.

- Do not use any accessories that have not been especially provided and recommended for this drill stand by the manufacturer.

Just because you can attach accessories to your drill stand is not a guarantee of safe use.

• Additional signs or other, non-BAIER-specific parts must not be screwed or riveted onto the drill stand.

This could damage the drill stand and cause malfunctions to occur.

• Note and follow all safety and work instructions for the accessories used.

- Never place the feed crank handle on the hexagon of the tapered shaft to tighten it.

Excessive torques could damage it.

2.6.9 Service / Maintenance / Repair

- If the power tool is dropped or becomes wet, have it checked.

A possibly damaged power tool is dangerous and no longer safe to operate. Before using the power tool again, have it checked by our customer service or an authorised service centre of Maschinenfabrik OTTO BAIER GmbH.

• Repair and maintenance work may only be carried out by an authorised workshop of Maschinenfabrik OTTO BAIER GmbH.

1) The given speeds are to be viewed as maximum speeds for the given wet diamond bit diameters. Depending on the property of the material to be drilled, such as concrete with steel reinforcement of different thicknesses, the speed is set "by feel". When drilling through concreted in steel with large wet diamond core drill bit diameters the 1st gear is always set.
2) Weight according to EPTA procedure 01/2003.
3) Measured values for noise determined according to EN 60745. Wear hearing protection!
4) Total vibration values (vector sum in three directions) determined according to EN 60745 The vibration emission values given in this instruction manual have been measured according to a method of measurement standardised in EN 60745 and can be used for comparison between power tools. They are also suitable for a preliminary estimate of the vibratory stresses. The vibration emission values given represent the main applications of the power tool. If the power tool is used for other applications, with different insert tools or are insufficiently serviced, this can significantly increase the vibratory stresses over the whole work period. For a precise estimate of the vibration emission values, the times during which the tool is switched off or is running but not actually in use should also be taken into account. This can reduce the vibration stresses over the whole work period significantly.

WARNING

Health risk due to vibrations.

Additional safety measures should be taken to protect the user, e.g. wearing anti-vibration protective gloves, correct maintenance of power tools and insert tools, keeping hands warm and good organisation of work sequences.

3.6 Intended use

Wet diamond drill

The BDB 8131 and BDB 817 wet diamond drills are designed for both hand-held operation and for use with a drill stand (with which it is possible to operate the drill with a water extraction kit).

NOTE

The wet diamond drills are not suitable for drilling overhead.

For hand-held drilling, the centring suction plate and a suitable water suction appliance (e.g. BAIER special dust extractor) is to be used.

The wet diamond drill, in conjunction with wet diamond core drill bits and a water supply, is intended for wet drilling into mineral materials such as concrete, reinforced concrete or masonry. Never work without water extraction.

The following materials may not be drilled: wood, metal and glass, etc.

Observe the relevant regulations in your country for the materials to be machined and extraction.

4 Before Starting Work

To ensure safe working with the wet diamond drill, the following points must be observed before each use:

• Read through all safety instructions and warnings in this instruction manual.
• Wear protective clothing such as hard hat, face protection or safety goggles, safety gloves, suitable half-face filter mask, slip-resistant safety footwear and if necessary an apron.
• The voltage on the rating plate must be identical with the mains voltage.
• Before each use, check the machine, connection cable, plug, secure fit of the wet diamond core drill bit and, if applicable, the fixing of the drill stand.
• Always note and follow the thread dimension of the wet diamond drill bit holder. The thread of the wet diamond core drill bits must fit on the thread of the wet diamond drill (G ^1/2 " internal thread or 1 ^1/4 " UNC external thread) without any clearance. Do not use reducers or adaptors to fit the wet diamond core drill bits.
• Check the condition of the wet diamond drill bit with a visual inspection.

NOTE

Damaged wet diamond core drill bits may not be used and must be replaced immediately.

- Only use diamond core drill bits recommended by OTTO BAIER GmbH for the respective area of use.

NOTE

The wet diamond core drill bit can become irreparably damaged by overheating or jamming in the drill core hole (see “Handling wet diamond core drill bits” on page 46).

If harmful dust is produced during the work, a suitable dust extractor must be connected to the wet diamond drill

(e.g. BAIER special dust extractor).

• Connect a suitable water extractor.
• The additional handle must be tightly screwed onto the drill for hand-held drilling.

4 Checking the personal protection switch

DANGER

Risk of injury due to electric shock.

The personal protection switch PRCD must be checked each time before the wet diamond drill is started up (see below). If the PRCD does not trip during the test or if it repeatedly switches off when the wet diamond drill is switched on, the wet diamond drill together with the PRCD personal protection switch must be examined by a qualified electrician.

• 4 With the mains plug pugged in and the wet diamond drill switched off, press the -ON-(RESET) button (2). The red indicator light (1) must light up.
• 4 Press the -OFF- (TEST) button (3). The PRCD must switch off, i.e. the red indicator light (1) goes out.
• 4 Press the -ON- (RESET) button (2) again. The wet diamond drill must now be able to be switched on.
• If the PRCD does not trip during the test or if it repeatedly switches off when the wet diamond drill is switched on, the wet diamond drill together with the PRCD personal protection switch must be examined by a qualified electrician.
• Operation of the wet diamond drill with a defective PRCD personal protection switch is not permitted – risk of fatal injuries.

5 Setting the speed

- 5 Set the appropriate speed for the core drill diameter (see "Technical Characteristics" on page 38) at the gear change knob (1).

NOTE

Changing gear while the machine is running can cause damage to the drill. Wait for the machine to completely stop.

2 Setting up drill stands (optional accessories)

Note and follow the following points before each use to ensure safe working with the drill stand:

• Before each use, check the fastening of the drill stand.
• Check that the drill sits securely in the drill stand.

• 6/7 Mounting the feed crank handle:

6 Push the feed crank handle (3), as required, to the left or right onto the pinion shaft (4) so that the drillhole in the feed crank handle (2) and in the pinion shaft (1) coincide.
7 Push the pin of the tube lock (1) through the matching holes (2) and push until the clip is snapped into position.

• 8 Blocking the feed:

By pulling the clamping lever (1) the spindle head (2) can be clamped and therefore protect the feeding device from unexpected movements.

5 Operation and Control – Hand-Held Operation

The additional handle must be tightly screwed onto the drill for hand-held drilling.

5.1 Fitting or changing the wet diamond core drill bit

DANGER

Risk of injury due to electric shock.

→ Disconnect the mains plug before carrying out any work on the wet diamond drill.

CAUTION

Risk of injury due to hot drill bits.

The drill bits fitted can get hot if used for a lengthy time. Wear safety gloves when changing the drill bits or allow the drill bits to cool first.

NOTE

If the wet diamond drill is used on a drill stand, the machine must be fixed in the motor collar before the diamond core drill bit is fitted.

• 9 Screw the wet diamond core drill bit (2) onto the 1 14 " UNC external thread or the wet diamond core drill bit (3) into the G 12 " internal thread of the output shaft (1), up to the limit stop (right-hand thread).
• 9 Use an open-ended spanner SW36 to hold the output shaft tight (1).

EN

• 9 Tighten the wet diamond core drill bit (2) using an open-ended spanner SW41.
• 9 Tighten the wet diamond core drill bit (3) using an open-end spanner SW22 or SW24.

NOTE

Check the fit and condition of the wet diamond core drill bit. A damaged wet diamond core drill bit may not be used and must be replaced immediately.

5.2 Connecting the water supply

DANGER

Risk of injury due to electric shock.

→ Protect the machine against splashing water. When inserting and removing the water hose, ensure that no water penetrates the air slits of the machine. Use intact Gardena couplings and Gardena hose lengths only. Check the sealing rings for wear or damage. The drill may not be run with leaking hose couplings.

• 10 Connect the water supply (1) with the coupling (3) to a hose with a Gardena hose connector ( 12 inch).
  • 10 The water supply can be switched on and off and finely controlled using the tap (2).
• Set the water flow rate as low as possible to avoid the risk of splashing/spraying.

5.3 Using the centring suction plate (accessories)

Use the drill for hand-held drilling only in conjunction with the BAIER centring suction plate and a suitable water suction appliance (e.g. BAIER special dust extractor). Before using the centring suction plate, the appropriate rubber sealing disc and centring disc for the wet diamond core drill bit diameter must be fitted. The centring suction plate is available as an accessory (see BAIER catalogue).

WARNING

Risk of injuries due to inadvertent loosening of the centring suction plate.

→ For long drill holes in the wall or floor, empty the water suction appliance in-between, as a full water suction appliance is no longer able to draw on the centring suction plate tight enough.
→ The base or surface on which the centring suction plate is positioned must be flat and impermeable to air.

• 11 Select centring disc (2) and rubber sealing disc (3) according to the diameter of the wet core drill bit.
- 11 Screw the rubber sealing disc (3) and centring disc (2) onto the centring suction plate (4). Screw materials: 3x hexagon socket head screw M6 (1), 3x washers M6 (5) and 3x hexagon nuts M6 (6).
• 12 Push the water suction hose (2) onto the socket (1).

NOTE

Greater effort may be required to push on the suction hose in cold ambient temperatures.

5.4 Switching on the wet diamond drill and drilling

• Use the drill for hand-held wet drilling only in conjunction with the BAIER centring suction plate (see page 42) and a suitable water suction device, e.g. BAIER special dust extractor (see BAIER catalogue).
• Before starting up the wet diamond drill, check all the points described in the "Before starting work" chapter (see page 40).
  • 4 Test the PRCD switch and switch on (see page 41).

NOTE

Changing gear while the machine is running can cause damage to the drill.

Wait for the machine to completely stop.

• 5 Set the appropriate speed for the core drill bit diameter at the gear change knob (1) (see "Technical Characteristics" on page 38).
  • 13 Align the centring suction plate (1) with the drill hole and hold tight.
• Switch the water suction appliance to continuous operation.
• Check whether the centring suction plate has tightly attached itself to the wall or floor.
• Always hold on tight to both handles of the wet diamond drill with two hands.

- With the wet diamond core drill bit at a standstill, feed it into the centring suction plate; the wet diamond core drill bit must not touch the wall or floor.

NOTE

The ON / OFF switch must not be locked for handheld drilling.

- 14 Press the ON / OFF switch (3) to switch on the wet diamond drill and wait until the working speed has been reached – green LED (1) lights up.

NOTE

Speed electronics with LEDs are provided for the BDB 817 only.

• 10 Open water supply (1) slightly.

WARNING

Risk of injury due to falling drill cores.

→ If drilling openings through objects, always check the rooms below or behind and block off the danger zone. Use formwork to secure the drill core against falling.

NOTE

The wet diamond core drill bit can become blunt or irreparably damaged due to overheating. The feed may only be as high as the wet diamond core drill bit can wear away the material. Therefore, do not exert too large a force on the wet diamond core drill bit and avoid canting. A suitable dust extractor must be connected to the wet diamond drill.

- Position the wet diamond core drill bit and drill with a uniform, light feed pressure.

- Always withdraw the wet diamond core drill bit slightly in-between times, to rinse out the drilling sludge.

NOTE

Speed electronics with LEDs are provided for the BDB 817 only.

• 14 If the feed is too fast, the red LED (2) lights up. Then, reduce the feed immediately until the green LED (1) lights up again.

If this warning signal is ignored, i.e. the feed is not reduced, the electronics switch off the wet diamond drill on overload.

The drilling process can then be started and continued as described above.

NOTE

The wet diamond drill also switches off if the wet diamond core drill bit has insufficient cutting power. In this case, check whether the wet diamond core drill bit has become blunt (see "Handling wet diamond core drill bits" on page 46). If the wet diamond drill is operated without water extraction, you must ensure that the escaping water is collected and does not cause any damage.

5.5 Ending the drilling process

NOTE

To avoid damage to the diamond segments, do not switch off the wet diamond drill until the rotating wet diamond core drill bit has been almost completely removed from the masonry.

• After reaching the required drilling depth, slowly withdraw the wet diamond drill with the rotating wet diamond core drill bit – the wet diamond core drill bit remains in the centring suction plate.
  • After drilling, briefly let the water continue running to flush out the drilling sludge between the wet diamond drill bit and the drill core.
  • 14 Release the ON / OFF switch (3) to switch off the wet diamond drill.
  • 10 Turn off the water supply (1).
  • Turn off the water extractor.
• Pull the now stopped wet diamond core drill bit out of the drill hole, and at the same time remove the centring suction disc with it.

Remove drill core

NOTE

Risk of fracture of the wet diamond core drill bit's cutting segments and/or damage to the drill. Never use the wet diamond core drill bit to break out the drill core!

• 15 Use a suitable tool (e.g. chisel) to break out the drill core in the wall.

6 Operation and Control – Stand-Guided Drilling

6.1 Installing the drill rig with plug fixing

The drill stand can be fixed onto the floor or wall using a retaining screw.

• 16 Use the wet diamond core drill bit to align the drill stand with the hole to be drilled:

• 20 Insert the drill (4) from above into the machine collar (2) of the drill stand up to the limit stop.
• 20 Re-tighten the cheese head screws (3).
- Repeat in the reverse order to remove the diamond drill from the drill stand.

6.4 Set guide clearance on spindle head

The spindle head must run without any clearance; it is adjusted using two hexagon head socket screws.

• 21 Release the clamping lever (1).
• 21 Undo both lock nuts (2).
• 21 Adjust both hexagon socket head screws (3) until the clearance is removed.
• 21 Tighten both lock nuts (2).
• 21 Turn the capstan handle (4) in both directions and check whether the spindle head (5) moves without clearance.

NOTE

The clearance is set correctly if, when the clamping lever is released, the spindle head with the mounted wet diamond drill does not move downward under its own weight or if so, moves very slowly.

6.5 Switching on the wet diamond drill and drilling

• Before starting up the wet diamond drill, check all the points described in the "Before starting work" chapter (see page 40 ff.).
• Select the core drill bit and fit (see "Fitting or changing the wet diamond core drill bit" on page 41).

NOTE

Changing gear while the machine is running can cause damage to the drill. Wait for the machine to completely stop.

- 5 Set the appropriate speed for the core drill diameter (see "Technical Characteristics" on page 38) at the gear change knob.

• 10 Open water supply (1) slightly.
- Set water suction to continuous operation.
• 14 Turn the capstan handle in a clockwise direction to slowly immerse the diamond core drill bit into the material to be drilled – the green LED (1) must not go out.

NOTE

Speed electronics with LEDs are provided for the BDB 817 only.

- As soon as the diamond drill bit has visibly immersed in the drilled material the feed can be increased.

NOTE

The diamond core drill bit can become blunt or damaged due to overheating. The feed may only be as high as the diamond core drill bit can wear away the material. Therefore, do not exert too much pressure on the diamond core drill bit (see "Handling wet diamond core drill bits" on page 46).

NOTE

Speed electronics with LEDs are provided for the BDB 817 only.

• 14 If the feed is too fast, the red LED (2) lights up. Then, reduce the feed immediately until the green LED (1) lights up again.
If this warning signal is ignored, i.e. the feed is not reduced, the electronics switch off the wet diamond drill on overload.
The drilling process can then be started and continued as described above.

NOTE

The wet diamond drill also switches off if the diamond core drill bit has insufficient cutting power. In this case, check whether the diamond core drill bit has become blunt (see "Handling wet diamond core drill bits" on page 46).

6.6 Ending the drilling process

• After drilling, allow the water to continue running for a short time to flush out the drilling sludge between the wet diamond core drill bit and the drill core.
• Turn the capstan handle counter-clockwise to pull the wet diamond core drill bit slowly out of the drillhole.
  • 14 Switch off the wet diamond drill.
  • 10 Turn off the water supply (1).

EN

Through-hole

NOTE

Risk of deformation or fracture!

Do not hit the diamond drill bit with hard objects! If the drill core is stuck in the diamond core drill bit, knock the diamond core drill bit with a soft piece of wood or plastic to loosen the drill core.

Non through-hole (blind hole)

NOTE

The diamond core drill bit can be damaged irreparably if it is jammed in the core drill hole. Never use the diamond core drill bit to break out the drill core!

• 15 If the drill core is still stuck in the drill hole after the diamond core drill bit has been removed, it can be broken out using a suitable tool (e.g. chisel).

7 Cleaning

DANGER

Risk of injury due to electric shock.

→ Disconnect the mains plug before carrying out any work on the wet diamond drill.

The machine must be cleaned after each drilling work session.

• If necessary, remove the wet diamond drill from the drill stand.
• Carefully clean the machine and blow out with compressed air.
• Lightly grease the thread of the wet core drill bit holder.
• If used, clean the centring suction plate under running water
• If used, carefully clean the drill stand and blow out with compressed air.

▶ Lightly grease the spindle head guide.

- Ensure handles are dry and free from grease.

8 Maintenance

DANGER

Risk of injury due to electric shock.

→ Disconnect the mains plug before carrying out any work on the wet diamond drill.

The wet diamond drill must be serviced at least once a year. Further, servicing will be necessary depending on the wear of the carbon brushes.

NOTE

BDB 8131

If using new carbon brushes, the machine may not be overloaded during the first 15 minutes of operation.

BDB 817

When using new carbon brushes, the machine may only be operated within the green range for the first 15 minutes - observe LED display in the handle (Item 1 and 2, see Figure 1).

Only servicing and repair firms authorised by Maschinenfabrik OTTO BAIER GmbH may carry out maintenance of the machine. Ensure that original BAIER spare parts and original BAIER accessories only are used (see BAIER catalogue).

9 Handling wet diamond core drill bits

• Always use and store wet diamond core drill bits in accordance with the manufacturer's instructions.
  • Too soft diamond segments:
  ▶ Wet diamond core drill bits wear too quickly at very high removal rate.
  Remedy: The material to be machined requires wet diamond core drill bits with a harder bond.

• Too hard diamond segments:

The diamond grains become blunt and do not break out of the bond. The wet diamond core drill bits no longer have any cutting power.

Remedy: The material to be machined requires wet diamond core drill bits with a softer bond.

- If water flushing is not used during machining, the wet diamond core drill bit increasingly rubs against "soft" drill dust. The core drill bit segments heat as a result, they become soft and

the diamond splinters sink into the substrate. The wet diamond core drill bit becomes less sharp. The cutting performance weakens and the user increases the pressure on the wet diamond core drill bit, which in turn increases the effect. After drilling a few holes, the wet core drill bit segments are "glazed" or they tear off at the least resistance in the stone and the wet diamond core drill bit must be replaced.

• Sharpening the wet diamond core drill bit using the BAIER professional whetstone (ID No. 15453) or a soft stone between drilling enables sunken in diamonds to be re-released and the wet diamond core drill bit is sharp again.
  • Water cooling of the core drill bit segments is necessary to extend the life of the wet diamond core drill bit and to keep the cutting speed high.
• Excessive drilling pressure can cause material fatigue in the base metal and therefore the formation of cracks. Before use, ensure that there are no cracks in the wet diamond core drill bit.
  • 14 The wet diamond core drill bit should plunge into the wall only after the working speed has been reached – green LED (1) lights up.

NOTE

Speed electronics with LEDs are provided for the BDB 817 only.

10 Disposal

Recycle the machine and its packaging in an environmentally friendly way in accordance with the provisions applicable in your country.
