Content of Delivery

Concrete grinder with diamond grinding wheel (PCD), tool kit and operating instructions in a metal case

Application for Indented Purpose

The concrete grinder is indented for professional use.

With an appropriate grinding wheel, the tool may be used for smoothing rough concrete, removing mould seams, residual mud, joint fillers and tile adhesives.

The machine may be used exclusively in conjunction with a diamond cup wheel and a vacuum cleaner of dust category M.

Only use grinding wheels recommended by the manufacturer.

These have a small weight and a high concentricity. Using other grinding wheels can cause an overload of the machine or damage of the bearings and danger to the user.

Safety Instructions

Safe work with the machine is only possible if you ead 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

For further safety instructions, please refer to the enclosure!

Electrical Connection

Before starting the machine check the correspondence between voltage and frequency according to the data mentioned on the identification plate. Voltage differences from +6% and -10% are allowed.

The grinder is made in protection class II.

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.

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

Switching on and off

Short-Time Operation

Switching-on: press the on/off switch

Switching-off: release the on/off switch

Permanent Operation

Switching-on: press the on/off switch and, keeping it pressed, engage the lock-on button

Switching-off: press the on/off switch and release it again

Attention!

In case of every stop of the machine or a power cut, the lock-on button has to be released immediately by pressing the ON/OFF switch. So you can avoid an unintentional restart of the machine (physical hazard).

Overload Protection

To protect operator, machine and tool the concrete grinder is equipped with an electronic overload protection:

To warn the user against an overload of the machine due to too high grinding pressure, a LED is attached to the motor housing. It does not light during idle run or at normal load. When the unit is overloaded the LED lights red, in this case, the unit must be stress-relieved. In case of longer non-observation of the red indication, the electronics will independently cut the unit off. You can continue working after having stress-relieved and switching OFF and ON the power tool again.

Changing the Diamond Grinding Wheel

Attention!

The grinding wheel might heat up enormously during operation. You could burn your hands or get cut or ripped by the segments.

Therefore, always use protective gloves when changing the grinding wheel.

Before any work on the tool, disconnect the plug from the mains!

First of all, the detachable hood segment has to be opened. Now you can hold up the driving disc between gearbox and grinding wheel by using a jaw wrench 32 (1). Use the face spanner (2) to unscrew the driving nut. Then remove the mounted grinding wheel respectively mount the new one. The assembly works the other way round!

Let the machine run for a short period of time and in a safe position. If the machine does not run easily, stop working immediately.

Use only original accessory!

Dust Extraction

Dust which occurs during your work is hazardous to health. That is why the concrete grinder must be used with a vacuum cleaner, and a dust mask has to be worn. The suitable Wet/Dry Vacuum Cleaners (dust category M) are available as accessory. It can directly be attached to the connection on the dust hood. The machine is designed according to the requirements mentioned in TRGS 559 (technical regulations for hazardous materials) article 4.3.

Changing the brush rim

If the length of the brushes is - due to wear - smaller than 5mm (extreme formation of dust during grinding), the brush rim has to be replaced completely. Therefore, remove the three fixing screws of the firm part of the dust guard and the two fixing screws of the detachable part. Pull out the worn brush rim and replace it by a new one. Pay attention that the fastening holes in the brush rim and the holes of the dust hood have the same same position. Screw both parts together.

Instruction for Use

Switch the machine on and put it carefully on the surface you want to work on. Hold the tool with both hands and work with circular or linear movements.

For best working results: Don't put too much pressure on the surface you want to work on.

For grinding works right into edges of the wall one segment of the dust guard can be removed by means of the chucking device. This allows grinding on surfaces which are usually hard to reach.

Attention! All other grinding works have to be done with the complete dust guard.

Function and Assembly of the Floor Guiding Device

Attention!

Before any work on the tool, disconnect the plug from the mains!

For grinding works on larger floors, a floor guiding device is available as accessory (not with PCD grinding wheel). It allows a more comfortable handling of the concrete grinder.

1 device with holder
2 top frame with weights
③ disc, spring ring, wing nut

Assembly

Lock the ON/OFF switch of the concrete grinder.

Put the top frame with the weights on the frame handle of the machine.

Then put the device with the holder 1 under the frame handle and fix it with disc, spring ring and wing nut on the top frame 2

Wind the line cord of the tool on the holder meant for this purpose. Make sure that the switch of the floor guiding device is not pressed or locked. Plug the grinder in the socket of the floor guiding device. Lead the hose of the vacuum cleaner above the floor guiding device, connect it with the grinder. The clamp will avoid a slipping of the hose.

Care and Maintenance

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

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

Due to its design, the machine needs a minimum of care and maintenance. However, the following points always have to be observed:

• Always keep the power tool and the ventilation slots clean.

• During work, please pay attention that no particles get inside the machine.

• In case of failure, a repair has to be carried out by an authorised service workshop.

Environmental Protection

Raw material recycling instead of waste disposal

To avoid damages on transportation, the power tool has to be delivered in a sturdy packing. Packaging as well as unit and 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 the 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

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 measures must be taken.

Wear ear protectors!

The typical hand-arm vibration is below 2.5m / s^2

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.

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 (dust 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

According to our general terms of delivery for business dealings, suppliers have to provide to companies a warranty period of 12 months for redhibitory defects (to be documented by invoice or delivery note).

Damages 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 is returned in non-dismantled condition to the manufacturer or an authorized Eibenstock service centre.
