Safety Instructions

**
Safe work with the machine is only possible if you read this operating instruction and follow the instructions contained strictly. 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.
The tool must neither be wet nor used in humid environment. **

• 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 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 dedusting 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.

• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring or its own cord. Cutting accessory contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

For further safety instructions, see the enclosure.

Electrical Connection

The EHD 1500 is designed according to protective class II. Prior to putting the tool into operation, check the mains voltage for conformity with the requirements of the tool’s nameplate. Voltage variations between + 6 % and – 10 % are permissible. The tool includes a start-up speed limiter to prevent fast expulsion fuses from unindented responding. Only use extension cables with a sufficient cross-section. A cross-section which is too small could cause a considerable drop in performance and an overheating of machine and cable.

Recommended minimum cross sections and maximum cable lengths

Additional Handle

For manual drilling, the EHD 1500 may be used only together with its additional handle which comes with the tools or in a drill rig. Place the handle on the gearing collar from the front and fix it by counterclockwise rotation.

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/OFF switch pressed, push in the arrestor button.
OFF: Press and release the ON/OFF switch again.

Attention!
Use the arrestor button only during operation with drill rig. Its use during manual operation is not allowed. If the machine stops for any reason or due to power failure, immediately release the arrestor button by pressing the ON/OFF switch.
The EHD 1500 is equipped with an electronic switch. With this switch the speed can be regulated according to the pressure on the button. Only use the electronic switch when you want to start or stop the machine in order to avoid material splashing around. A permanent use with reduced speed can cause an overload because the motor then gets less cooling air and therefore the machine will be overheated much faster.

Drill Bits

The EHD 1500 is equipt with a spindle connection M18.
For drill bits with M16 male threads, an adapter (Order Number 35512000) is available as add-ons.
The EHD 1500 is equipt with a dust extraction for drill bits M16 (Order
Number: 35472000, 35474000, 35475000, 35476000)
Make sure that the diamond segments have sufficient cutting clearance towards the bit body.

Changing Drill Bits

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.
Therefore, always use protective gloves when changing the drill bit.
The drilling spindle has a right-hand thread.
To ease screwing on and off, always use a SW 24 open-end wrench at the drilling spindle. Never use a hammer, because this may damage both the drill bit and the tool.

Drilling

Dust which occurs during your work is hazardous to health. That is why it is advisable to use a deduster and to wear a dust mask on dry drilling. As a suitable wet/dry deduster, our ESS 35 MP is available as add-on. The use of a dedusting system is also a prerequisite for optimal cutting performance of the bit (air cooling). For the selection of the appropriate drill bits for different materials please pay attention to the specifications of the drill bit manufacturers.
Insert the centering drill on the working spindle of the dust extraction. Fix the required dry drill bit on the working spindle of the dust extraction.

Operate the ON/OFF switch and drill until the segments are approximately 5 mm in the material. Remove the centering drill. Refix the drill bit to the existing groove and complete your drilling. Advance the tool according to bit diameter and machine power. In case the bit gets jammed, to not dry to release it by switching the tool on and off. This would cause premature wearing of the safety clutch. Switch the tool off immediately and unfix the drill bit by turning to the left or right using an appropriate open-end wrench. Cautiously pull the tool out of the borehole.

Overload Protection

To protect the user, motor and drill bit, the EHD 1500 is equipped with a mechanical, electrical and thermal overload protection. Mechanical:

In the event of a sudden jamming of the drill bit, the machine’s kickback is limited to a reaction torque controllable by the operator by means of a slip clutch.

Electrical:

To warn the user against overstressing the tool by applying to high an advance force, the handle includes a LED as a overload indicator. It does not light during idle run or at normal load. At overload, it lights red. In that case the tool most be stress-relieved. In case of longer non-observation of the rad indication, the electronics will independently switch the tool off. After relieving be switching the tool off and on, the work can be continued as normal.

Thermal:

In case of permanent overload, a thermocouple protects the motor against destruction. Here also, the user is warned by the overload indicator. Shortly before the maximum temperature is reached, the indicator flashes red. In that case, the tool switches off and can only be restarted after a certain cooling- down period (approx. 2 minutes). The overload indicator flashes until the machine has cooled sufficiently and can be used again. The cooling-down time depends on the temperature of the motor winding and ambient temperature.

Safety Clutch

The slip clutch served for compensation of shocks and overload. To keep its functionability, it should not slip for more than 2 seconds. In case of excessive wearing, it can be replaced by an authorized service centre.

Care and Maintenance

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

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:

• The electric tool as well as the ventilation slots always has to be clean.
• During work, please pay attention that no foreign elements get into the interior of the machine.
• 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/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.

Noise Emission

Measured sound values determined according to EN 62841-2-1. Typically the A-weighted noise levels of the product are:
Sound pressure level LpA: 88 dB(A)
Sound power level LwA: 91 dB(A)
Uncertainty: K 3 dB

Wear ear protectors!

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 ESS 35 MP 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

According to the general supply conditions for business dealings, suppliershave to provide to companies a warranty period of 12 months for redhibitory defects. (To be documented by invoice or delivery note). Damage due to natural wear, overstressing or improper handling are excluded from this warranty. Damages due to material defects or production faults shall be eliminated free of charge by either repair or replacement. Complaints will be accepted only if the tool was returned in non-dismantled
