1 Safety warnings

1.1 General Power Tool Safety Warnings

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference!

The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

1) Work area safety

a) Keep work area clean and well lit. Cluttered or dark areas invite accidents.

b) Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

c) Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

2) Electrical safety

a) Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

b) Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

c) Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

d) Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

e) When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

f) If operating a power tool in a damp location is unavoidable, use a residual current device (RCD) protected supply. Use of an RCD reduces the risk of electric shock.

3) Personal safety

a) Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.

b) Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask, non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.

c) Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energising power tools that have the switch on invites accidents.

d) Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.

e) Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.

f) Dress properly. Do not wear loose clothing or jewellery. Keep your hair, clothing and gloves away from moving parts. Loose clothes, jewellery or long hair can be caught in moving parts.

g) If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

4) Power tool use and care

a) Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.

b) Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.

c) Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.

d) Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

e) Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool's operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.

f) Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control..

g) Use the power tool, accessories and tool bits etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.

5) Service

a) Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

1.2 Special safety instructions for drills

• Use auxiliary handle(s), if supplied with the tool. Loss of control can cause personal injury.
• Hold power tool by insulated gripping surfaces, when performing an operation where the cutting accessory may contact hidden wiring. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.

1.3 Further safety instructions

• Check the plug and cable on a regular basis and, if they are damaged, have them replaced by an authorised customer service workshop.
• The switch must be in the OFF position before you connect it to the mains.
• Always guide the power cable from the tool to the rear. Never pull hard on the power cable and never place it on or guide it over any sharp edges.
• Only work in a safe and stable position.
• Do not work in damp environments.
• If moisture has penetrated the power tool, unplug the mains plug and have the power tool checked by an authorised customer service workshop.
• Do not touch the connected power tool with wet hands.
• Wear suitable personal protective equipment: Ear protection, protective goggles, dust mask for work that generates dust and protective gloves when changing tools, sturdy shoes.

1.4 Other risks

Even in cases where the machine is used correctly and all relevant safety instructions have been adhered to, the design engineering of the machine and its operation mean that the following safety risks may also arise:

– Danger caused by the power cable.

• A concentration of dust which is harmful to health when working in an area that is not sufficiently ventilated.
• Injuries caused by touching electrified parts when removing the machine or its parts if the plugs on the power cable have not been removed from the socket.

- You must only use original spare parts.

2 Information about noise level and vibrations

The values have been measured in conformity with EN 62841. Drilling

Acoustic pressure level L_pA = 84.5 dB (A).

Acoustic power level L_wA = 95.5 dB (A).

In accuracy of measurements K = 1.5 dB (A).

Percussion drilling

Acoustic pressure level L_pA = 94.9 dB (A).

Acoustic power level L_wA = 105.3 dB (A).

In accuracy of measurements K = 1.5 dB (A).

ATTENTION! Noise is generated during work! Use ear protection!

Vibration emission value ah (vector sum for three directions) and uncertainty K measured in accordance with EN 62841:

Drilling a_h=3.0 m.s^-2

Percussion drilling a_b=13.0 m.s^-2 .

In accuracy of measurements K = 1.0 m.s ^-2 .

The emission values specified (vibration, noise) were measured in accordance with the test conditions stipulated in EN 62841 and are intended for machine comparisons. They are also used for making preliminary estimates regarding vibration and noise loads during operation.

The emission values specified refer to the main applications for which the power tool is used. If the electric power tool is used for other applications, with other tools or is not maintained sufficiently prior to operation, however, the vibration and noise load may be higher when the tool is used.

Take into account any machine idling times and downtimes to estimate these values more accurately for a specified time period. This may significantly reduce the load during the machine operating period.

5 Double insulation

To ensure maximum safety of the user, our tools are designed and built to satisfy applicable European standards (EN standards). Tools with double insulation are marked by the international symbol of a double square. These tools must not be grounded and a two-wire cable is sufficient to supply them with power. Tools are shielded in accordance with EN 55014.

6 Use

The machine is intended for impact drilling in brick, concrete and stone as well as for drilling in wood, metal, ceramics and plastics. Machines with electronic control and right/left rotation are also suitable for screwing and thread-cutting.

The user bears full responsibility for the consequences of using the tool for purposes other than the above.

7 Commissioning

Any unauthorised use might cause damage to the tool. Therefore follow these instructions:

– Always use sharp drill bits.

- Load the tool to avoid any significant reduction of speed or stoppage.

- Always change the speed gear when the machine is idle or at the machine slow-down at low speed, in no case during the drilling or when the machine is otherwise loaded.

Check that the information on the production plate matches the real voltage of the power source.

Check that plug matches the type of socket.

Tools designed for 230 V can also be connected to 220/240 V.

ATTENTION! Noise is generated during work! Use ear protection!

7.1 Additional handle

For safety reasons always use the additional handle [11], firmly mounted on the clamping neck [3]. The stop bar [12] can be used to adjust the drilling depth. By rotating the handle the position of the addition al handle and the depth stop can be modified.

7.2 Clamping of drill bits

Chuck with ring gear

Open the chuck to allow mounting of the tool. Mount the tool on. Mount the tool on and, using the chuck hook [13] clamp in evenly.

Quick-tightening chuck

Open the chuck to allow mounting of the tool. Mount the tool on.

Tighten the quick-tightening chuck by your hand so strongly that a "click" sound is heard clearly. Thus the chuck will be secured automatically.

This lock will release again if you turn the sleeve contra directionally to remove the tool.

Be careful as the chuck gets hot:

In case of longer work tasks, especially in impact drilling, the chick might get very hot. In this case you are

recommended to wear protective gloves.

7.3 Switching on and off

By pressing the switch button [7] the machine activates and releasing the button stops it.

7.4 Permanent run

By pressing the switch button [7] to the stop and simultaneous pressing the latching pin [6] permanent run is achieved.

Repeated pressing the switch button [7] and its release the permanent run is discontinued.

7.5 Speed control

By light and gradual pressing the controller button [7] you will achieve low speed and controlled continuous run-up.

By further gradual pressing the button the speed increases to the pre-selected speed.

7.6 Electronic speed pre-selection

Using the pre-selection wheel [8] the required pre-selected speed is set - even if the machine runs. The necessary speed depends on the type of the material drilled, and a practical test is recommended to verify it.

If the machine is loaded considerably, adjust the pre-selection wheel [8] to the marginal position in the + direction (max speed - control disconnected).

After a longer work at low speed leave the machine run idle for 3 minutes at maximum speed to cool the engine down.

7.7 Gear shifting

Use the speed lever [10] to adjust the 2 speed gear:

1st Speed – lower speed gear – higher torque

2nd Speed – higher speed gear – lower torque

In any speed gear you can adjust the final speed by means of the electronic pre-selection. However, firstly select the mechanical speed gear.

Changing the gears can be done at slowing the machine down or in idle run but never when the machine is fully loaded. Once the gear is changed, leave the machine start up slowly

7.8 Change in rotation

Adjust the rotation direction switch [9] to the right (left run) or to the left (right run). The left run allows e.g. cutting the threads and unscrewing of bolts or nuts.

Changing is blocked if the controller button is pressed. The rotation direction has to be changed when the machine is idle.

WARNING! If the left run is used, the chuck has to be screwed on very firmly.

7.9 Drilling and impact drilling

Use the impact lever [4] to gear the impact up or down. The shifting can be done even when the machine runs.

Drilling

Shift the gear lever [4] to the left towards the drill-bit symbol.

Impact drilling

Shift the gear lever [4] to the right towards the hammer symbol.

The impact drilling is recommended to be used in concrete, brickwork and earthenware. The switch lever [9] must be always shifted to the right run.

7.10 Removing the chuck with ring gear (Fig.)

Hold the spindle on the surface [2] using an open wrench (13 mm). Insert the chuck hook [13] into a single opening on the chuck and by turning left screw the chuck out. Release the firmly clamped chuck by impacts of the hammer on the chuck hook [13].

7.11 Removing the quick-tightening chuck (Fig.)

Clamp the hexagonal wrench [15] into the chuck. Hold the spindle on the surface [2] using a spanner (13 mm). By turning the chuck to the left using the hexagonal wrench screw the chuck together. Release the firmly clamped chuck by impacts of the hammer on the hexagonal wrench.

Proceed in reverse sequence to screw the chuck on.

7.12 Power Plug

WARNING! Risk of injury if the power tool is used with incorrect mains power supply.

The power tool may only be used with single-phase alternating current with rated voltage of 220–240 V / 50–60 Hz. The power tool has double insulation against injury by electric current in line with standard EN 62841 and features integrated interference elimination in line with standard EN 55014.

Before turning the tool on, check that the information on the production plate matches the real voltage in the socket.

The power cable can be extended if needed as follows:

- 20 m length, conductor cross section: 3 × 1.5 ~mm^2

- 50 m length, conductor cross section: 3 × 2.5 ~mm^2

Only use extension cables designed for outdoor use and bearing the appropriate markings.

Operation with an Electric Generator (EG) with a Combustion Engine

The manufacturer of the tool cannot guarantee faultless operation with all EGs.

The tool can be used with an EG if the following conditions are met:

» The output voltage of the EG must always be in 230 VAC ±10 % range. The EG should be fitted with automatic voltage regulation (AVR). Without AVR, the tool may not work correctly and may even get damaged!
» The power of the EG must be at least 2.5 times higher than the input power of the tool.
» Using the power tool with an EG with insufficient power may result in speed fluctuations and reduced output of the tool.

8 Work instructions
