Application for Indented Purpose

The diamond core drill PLD 182.1 NT is indented only for professional use and may be used only by instructed personnel. It may be used either with or without a suitable diamond drill rig. With an appropriate drill bit, the tool can be used for wet cutting of concrete and stone and dry cutting of bricks, sand-lime bricks and pore concrete. For wet drilling jobs with diameters above 70 mm and drilling in the 1 st gear, it is a must to use a suitable drill rig. Drilling in the 1 st gear without drill rig is prohibited! On careless use, counter torques may cause danger to the user!

Safety Instructions

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 may fall downward.
The tool must neither be wet nor used in humid environment.

• 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.
• 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 stops for any reason. So you avoid sudden starts in unattended condition.
• Don’t use the machine if a part of the housing is damaged or in case of damages on the switch, the cable or plug.
• 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.
• On using the tool, in no case cooling water may seep into the motor or the electric components.
• If water comes out of the drainage hole at the gear neck, stop your work and have the tool repaired by an authorised service centre.
• Perform overhead drilling only with suitable protective appliances (water catcher).
• When performing drilling that requires the use of water, route the water away from the operator’s work area or use a liquid collection device. Such precautionary measures keep the operator’s work area dry and reducethe risk of electrical shock.
• When the bit is jammed, stop applying downward pressure and turn off the tool. Investigate and take corrective actions to eliminate the cause of the bit jamming.
• When restarting a diamond drill in the workpiece check that the bit rotates freely before starting. If the bit is jammed, it may not start, may overload the tool, or may cause the diamond drill to release from the workpiece.
• Always wait until the machine has come to a complete stop before placing it down. The tool insert can jam and lead to loss of control over the power tool.
• 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.
• When securing the drill stand with anchors and fasteners to the workpiece, ensure that the anchoring used is capable of holding and restraining the machine during use. If the workpiece is weak or porous, the anchor may pull out causing the drill stand to release from the workpiece.
• When securing the drill stand with a vacuum pad to the workpiece, install the pad on a smooth, clean, nonporous surface. Do not secure to laminated surfaces such as tiles and composite coating. If the workpiece is not smooth, flat or well affixed, the pad may pull away from the workpiece.
• Ensure there is sufficient vacuum before and during drilling. If the vacuum is insufficient, the pad may release from the workpiece.
• Never perform drilling with the machine secured by the vacuum pad only, except when drilling downwards. If the vacuum is lost, the pad will release from the workpiece.
• When drilling through walls or ceilings, ensure to protect persons and the work area on the other side. The bit may extend through the hole or the core may fall out on the other side.
• Ensure that the drill is securely attached to the drill stand before using it. Otherwise, the drill may slip in the drill stand, which can lead to a loss of control.
• Secure the drill stand on a stable and even surface. If there is a chance that the drill stand will slip or wobble, the safe and steady operation of the drill cannot be guaranteed.
• Store idle drill stands out of the reach of children. Do not allow persons unfamiliar with the tool or these instructions to operate the tool. Tools can be dangerous in the hands of untrained users.
• Before carrying out any work on the drill stand or drill, during work breaks and when not using the drill stand, secure the drill stand against unintentional movement by tightening the parking brake.
• The safety and operating instructions for the drill stand and the accessories being used are to be strictly observed!
• Always work in a carefully considered way and do not use the tool if you are lacking consideration.
• Store the machine in a safe manner when not being used. The storage location must be dry and lockable. This prevents the machine from storage damage, and from being operated by untrained persons.

For further safety instructions, see the enclosure.

Electrical Connection

The PLD 182.1 NT is made in protection class I. For protection purposes the machine can only be run with a GFCI. The machine is standard equipped with a PRCD switch in the cord which allows to connect the unit direct to a 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 starting your work, check the proper function by pressing the TEST button.

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.
Use only extension cable with sufficient cross-section (min. 2,5 mm2). A cross-section which is to small could lead to excessive power loss and to overheating the motor and the cable.
Recommended minimum cross sections and maximum cable lengths

The tool includes a start-up speed limiter to prevent fast expulsion fuses from unindented responding.

Additional Handle

For manual drilling, the PLD 182.1 NT may be used only together with its additional handle which comes with the tools.
Place it on the gearing collar from the front and fix it by turning the handle in 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/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.
If this button is not released, the tool may unintendedly restart if the PRCD protective switch is operated and cause a danger to the user.

Water Supply

Place the adapter with the ball valve onto the tool’s connector and turn into the direction of the arrow up to the stop. Connect the tool to the water supply system or a water pressure vessel using the push fit nipple.
Attention! The maximum water pressure should not exceed 3 bars. In case of higher water pressure, a pressure relieve valve must be used.
The connector for the tool should be a GARDENA hose connector. You can obtain it from your local dealer. Use only pure tap water.
If water comes out of the drainage hole at the gear neck, stop your work and have the tool repaired by an authorised service shop.
Pay attention that neither persons in the working area nor the power tool itself come into contact with the water that comes out.

Dust Exhaustion

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. Place the adapter for the dedusting unit onto the tool’s connector and turn into the direction of the arrow up to the stop. As a suitable wet/dry deduster, our DSS 35 M iP is available as add-on. The use of a dedusting system is also a prerequisite for optimal cutting performance of the bit (air cooling).

Manual Drilling

Open the ball valve and switch the tool on. Hold the tool tight with both hands. Locate the tool slightly inclined. Once the drill bit is in the material (approx. 1/8 to 1/4 of the circumference), bring the tool into an angle of 90 degrees and continue drilling. Take care that the drill bit is not out of line. Advance the tool according to bit diameter and machine power. Observe the LED in the handle. If it lights red, reduce your pressing force. 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.
Use of a water suction ring is mandatory for „overhead drilling“.

Drill Bits

Diamond drill bits with a 1 ¼” UNC female thread and R ½” male thread can be screwed directly onto the working spindle.
Use only appropriate drill bits for the material to be drilled in. You can protect your tool by using only well balanced drill bits without deformation.
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 32 open-end wrench at the drilling spindle. Never use a hammer, because this may damage both the drill bit and the tool.
Some water-resistant grease on the drilling spindle threat or a copper ring between spindle and drill bit will simplify removal of the drill bit.

After Drilling

When you have finished drilling:

• Pull the drill bit out of the hole.
• Turn the motor off 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 (if possible).
• 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 reusable.

Removal of the core by 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 with a dowel in the core, screw an eyebolt in and pull the core out.

Rig Drilling

Since the drill rig does not belong to the supply, some of its most important features are described here.
For this purpose, please refer to the drill rig’ s operating instructions.
Vacuum fastening:
For the vacuum, make sure that it is sufficient (minimum -0.8 bar). Make sure that the gaskets are not worn.
Attention! Do not use the vacuum fastening on the wall or overhead!
Please ensure that the leveling screws are adjusted in such a way that they do not protrude from the underside of the drill stand foot, otherwise the vacuum is affected and the stand may come away from its support.
Dowel fastening:
The most common way of fixing is dowel fixing.
If possible, use only metal dowels. The dowel diameter must not be smaller than 12 mm.

• In order to fasten the drilling unit correctly, you need the fastening set (order number 35720000).
• Drill a hole with a diameter of 16 mm, 50 mm deep. Make sure that the hole is free of dust.
• Insert a dowel and open it with an expanding mandrel.
• Screw the thread rod into the dowel.
• Put the drilling unit with the deep hole in the base onto the thread rod.
• Place the washer and screw the butterfly nut very tightly.
• Adjust the drilling unit in the platform by using the four screws.

Overload Protection

To protect the user, motor and drill bit, the PLD 182.1 NT 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.

Safety Clutch

The safety clutch should absorb shock and excessive stress. It is an aid and not an absolute protection. Therefore, you have to handle and drill carefully. To keep it in good condition, the clutch should slip for a very short time (max. 2 seconds) in each case only. Slipping for longer periods destroys the safety clutch. After excessive wearing the clutch has to be renewed by an authorized service shop.

Care and Maintenance

Before the beginning of the maintenance- or repair works you have to disconnect plug from the mains.
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 the first 150 hours of operation, the gearing oil must be changed.
  Gearing oil changes bring about an essential increase of the tool’s lifetime.

• 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/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 / Vibration

Measured sound values determined according to EN 62841-2-1.
Typically the A-weighted noise levels of the product are:
Sound pressure level LpA 85 dB(A)
Sound power level LwA 96 dB(A)
Uncertainty K 3 dB
Wear ear protectors!
Vibration total values ah and uncertainty K determined according to EN 62841-2-1:
Vibration emission value ah 2,5 m/s 2
Uncertainty K 0,3 m/s 2
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.
