Application for Indented Purpose

The EHD 2002 S diamond core drilling machine is intended for commercial use and may only be operated by trained personnel. It can be used either in a suitable diamond drilling stand or freehand. In conjunction with a dust extraction system and suitable drill bits, it is designed for drilling in brick, sand-lime brick, aerated concrete and similar materials (excluding concrete and stone).

Safe use of the tool is only possible if the user had studied the instruction manual and safety instructions completely and is strictly following the instructions contained therein. Additionally, the general safety instructions of the leaflet supplied with the tool must be observed. Prior to the first use, the user should absolve a practical training. Save all warnings and instructions for future reference.

If the mains cable gets damaged or cut during the use, do not touch it, but instantly pull the plug out of the socket. Never use the tool with damaged mains cable.

Prior to drilling in walls and ceilings, check them for hidden cables, gas and water pipes and other media.

Check the working area, e.g. using a metal detector.

Prior to the start of your work, consult a statics specialist to determine the exact drilling position.

If drilling through ceilings, secure the place below, because the drill core may fall downward.

Do not expose power tools to rain or wet conditions.

Water entering a power tool will increase the risk of electric shock.

• Do not use the tool in an environment with danger of explosion.
• Do not use the tool standing on a ladder.
• Do not drill into asbestos-containing materials.
• Do not carry the tool at its cable, and always check the tool, cable and plug before use. Have damages only repaired by specialists. Insert the plug into the socket only when the tool switch is off.
• Modifications of the tool are prohibited.
• Unplug the tool and make sure that the switch is off if the tool is not under supervision, e.g. during preparation and take-down works, at power failures, for insertion or mounting accessories.
• Unplug the tool if it is stops for any reason. So you avoid sudden starts in unattended condition.
• Do not use the tool it its shell, switch, cable or plug are damaged.
• Always lead the mains and extension cables as well as the deducting hose from the tool to the back.
• Electrical tools have to be inspected visually by a specialist in regular intervals.
• The tool may be used only in two-hand operation or with the drill rig.
• Keep the handles dry, clean, and free of oil and grease.
• Do not touch rotating parts.

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

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

• During manual operation, always hold the tool with both hands and be fall-safe. Consider the tool's reaction torque in case of blocking.
• Always work with concentration. Always work in a carefully considered way and do not use the tool if you are lacking consideration.
• During manual operation, work with a special circumspection when dry drilling with dimensions between 100 and 132 ~mm !

For further safety instructions, see the enclosure.

Electrical Connection

The EHD 2002 S is designed in protection class II.

The device is equipped with a start-up current limiter. This prevents the quick-acting circuit breakers from being triggered unintentionally. Before commissioning, check that the mains voltage and mains frequency match the specifications on the type plate. Voltage deviations of +6% and -

10% are permissible. Only extension cables with a sufficient cross-section (see table) may be used, as an insufficient cross-section can lead to excessive power loss and overheating of the machine and cable.

Recommended minimum cross sections and maximum cable lengths

Mains voltage	Cross section in sq. mm
1.5 2.5
110V 20 m 40	m
230V 50 m 80	m

Additional Handle

In manual mode, the EHD 2002 S may only be operated in conjunction with the additional handle provided.

This is attached to the front of the gear neck and tightened by turning the handle in the direction of the arrow.

Switching ON and OFF

Short-time operation

ON: Press the ON/OFF switch

OFF: Release the ON/OFF switch

Long-time operation

ON: Keeping the ON/Of switch pressed, push in the arrestor button.

OFF: Press and release the ON/OFF switch again.

Attention!

• Only use the locking button when the machine is stationary. Use in manual mode is prohibited.
  In the event of any machine-related standstill or interruption to the power supply, the locking button must be released immediately by pressing the on/off switch.

• The machine is equipped with an electronic control switch with a locking mechanism.

• The further the switch button is pressed, the higher the speed. This makes it easier to drill accurately.
  In normal operation, always work at full speed.
• Continuous operation at reduced speed leads to overload, as less cooling air is available to the motor, causing it to overheat significantly faster.

Changing Gears

• The EHD 2002 S has a 2-speed gearbox.
• Adjust the speed to the drill diameter.
• Turn the gear switch to the next higher or next lower gear.
• If the machine cannot be shifted, support the shifting process by slightly turning the work spindle.
• Switching on and off briefly can also make it easier to select the gear.

Warning!

• Only switch the gearbox when it is at a standstill!
• Never switch by force!
• Do not use tools such as pliers or hammers to switch the gearbox!

Drill bits

Only use drill bits that are suitable for the material to be drilled. You will protect the core drilling machine by only using round drill bits that are not deformed. Ensure that the diamond segments are sufficiently free to cut from the drill bit body.

Changing Drill bit

Caution!

The tool may become hot during use or grinding. You may burn your hands or cut or tear yourself on the segments.

Therefore, always wear protective gloves when changing tools.

The drill spindle has a right-hand thread. Always use a 24mm open-end wrench as a counterholder, which is placed on the drill spindle.

Never loosen the drill spindle by striking it (with a hammer), as this will damage the drill spindle and the core drilling machine.

Applying a little waterproof grease to the thread of the drill spindle and a copper ring between the spindle and the drill bit will make it easier to loosen the drill bit.

Drilling with extraction

The dust produced during operation is harmful to health. When dry drilling, a dust extraction system must therefore be used or a dust mask worn. A dust extraction system is available for the EHD 2002 S, which allows the direct use of drill bits with a 114 thread connection. The appropriate wet/dry vacuum cleaner for dust class M is available as an accessory. The use of a dust extraction system is also a prerequisite for optimum cutting performance of the drill bit (air cooling). When selecting the appropriate drill bits for different materials, please observe the specifications of the drill bit manufacturer. Insert the centring tip so that it engages in the working spindle. Then screw the appropriate dry drill bit onto the working spindle.

Press the on/off switch and drill until the segments have penetrated approx. 5 mm into the material to be drilled. Then remove the centring tip. Next, insert the drill bit into the existing groove and finish drilling. Adjust the feed rate to the bit diameter and the power of the machine.

If the drill bit jams, do not try to loosen it by switching the machine on and off. This will cause premature wear of the safety slip clutch. Switch off the machine immediately and loosen the drill bit by turning it clockwise and anticlockwise with a suitable open-end wrench. Carefully pull the machine out of the drill hole.

After drilling

Remove the drill core if it remains in the drill bit

• Disconnect the drill bit from the motor (if possible).
• Place the drill bit vertically.
• Tap the pipe lightly with a wooden mallet until the drill core slips out. Never strike the drill bit against a wall with force or use tools such as hammers or open-ended spanners, as this will deform the pipe and make it impossible to remove the drill core or reuse the drill bit.

Removing the drill core from a blind hole

Break the core with a wedge or lever. Lift out the core with suitable pliers or drill a hole in the core, screw in a ring screw with a suitable dowel and pull out the core.

Overload protection

The EHD 2002 S is equipped with mechanical, electronic and thermal overload protection to protect the operator, motor and drill bit.

Mechanical: If the drill bit suddenly jams, the machine's recoil is limited to a reaction torque that can be controlled by the operator by means of a slip clutch.

Electronic: In the event of an overload, the machine switches off automatically via the electronics. After the load has been removed and the device switch has been switched off and on again, normal operation can continue.

Thermal: A thermocouple protects the motor from damage in the event of prolonged overload. In this case, the machine switches off automatically and can only be restarted after it has cooled down sufficiently (approx. 2 minutes). The cooling time depends on the temperature of the motor winding and the ambient temperature.

Safety Clutch

The safety clutch is designed to absorb shocks and excessive loads. It does not provide absolute protection, so you should drill with caution.

To maintain its functionality, it should slip for a maximum of 2 seconds. Prolonged slipping will destroy the safety clutch. If it is excessively worn, it must be replaced by an authorised specialist workshop.

Care and Maintenance

Before starting maintenance or repair work, be sure to disconnect the power plug!

It is a must to unplug the tool before starting any service or repair works. Repairs may be executed only by appropriately qualified and experienced personnel. After every repair, the unit has to be checked by an electrical specialist. According to its design, the tool requires a minimum of care and maintenance. However, the following maintenance works and component checks have to be performed in regular intervals:

• Clean the tool after completion of your work. Apply some grease onto the drilling spindle thread. The ventilation slots must always be clean and unclogged. Make sure that now water gets into the tool during cleaning.

• After approx. 250 hours of operation, the carbon brushes must be checked and, if necessary, be replaced by an authorized specialist (use only original carbon brushes).

• Once per quarter of a year, an electrical specialist should check the switch, cable and plug.

Our after-sales service responds to your questions concerning maintenance and repair of your product as well as spare parts.

EIBENSTOCK's application service team will gladly answer questions concerning our products and their accessories.

Environmental Protection

Raw material recycling instead of waste disposal

To avoid damages in transit, the tool is supplied in a sturdy packing. The packing as well as the tool and its accessories are made of recyclable materials which enable environmentally friendly and sortwise disposal by the local reception points.

Only for EU countries

Do not dispose of electric tools together with household waste material!

In observance of European Directive 2012/19/EC 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.

Noise Emission

The indication of noise emission is measured after EN 62841-2-1. The level of acoustic pressure on work site could exceed 85 dB (A); in this case protection means must be used.

Wear ear protectors!

Vibration total values a_h and uncertainty K determined according to EN 62841-2-1:

Vibration emission value

an 3,9 m/s²

Uncertainty

K 1,5 m/s²

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.

Dust protection

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). Material containing asbestos must only be treated by specialists.

• Where the use of a dust extraction device is possible it shall be used.
• To achieve a high level of dust collection, use industrial vacuum cleaner (category M) for wood and/or minerals together with this tool.
• The work place must be well ventilated.
• The use of a dust mask of filter class P2 is recommended.

Warranty

In accordance with our General Terms and Conditions of Delivery, a warranty period of 12 months applies to material defects in business transactions with entrepreneurs (proof by invoice or delivery note).

This does not include damage resulting from natural wear and tear, excessive use or improper handling. Damage resulting from material or manufacturing defects will be repaired free of charge by repair or replacement. Complaints can only be accepted if the device is returned to the supplier or an Eibenstock authorised repair shop in its unassembled state.
