1.- Machine-specific SafetyWarnings

Wear hearing protection. Exposure to noise can cause hearing loss.
Always use the auxiliary handle supplied with the machine. Loss of control can cause personal injury.
Use suitable detectors to determine if utility lines are hidden in the work area or call the local utility company for assistance. Contact with electric lines can lead to fire and electric shock. Damaging a gas line can lead to explosion. Penetrating a water line causes property dama electric shock.ge or may cause an
Hold the power tool only by the insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a "live" wire will also make exposed metal parts of the power tool "live" and shock the operator.
When working with the machine, always hold it firmly with both hands and provide for a secure stance. The power tool is guided more secure with both hands.
Secure the workpiece. A workpiece clamped with clamping devices or in a vice is held more secure than by hand.
Do not work materials containing asbestos. Asbestos is considered carcinogenic.
Take protective measures when dust can develop during working that is harmful to one's health, combustible or explosive. Example: Some dusts are regarded as carcinogenic. Wear a dust mask and work with dust/chip extraction when connectable.
- Keep your workplace clean. Blends of materials are particularly dangerous. Dust from light alloys can burn or explode.
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.

Never use the machine with a damaged cable. Do not touch the damaged cable and pull the mains plug when the cable is damaged while working. Damaged cables increase the risk of an electric shock.

Rotating the Auxiliary Handle

The auxiliary handle 11 can be set to any position for a secure and low-fatigue working posture.

Turn the bottom part of the auxiliary handle 11 in counterclockwise direction and swivel the auxiliary handle 11 to the desired position. Then retighten the bottom part of the auxiliary handle 11 by turning in clockwise direction.

Pay attention that the clamping band of the auxiliary oned in the groove on the housing handle is positive as intended for.

3.2.- Changing the Tool

The dust protection cap 3 largely prevents the entry of drilling dust into the tool holder during operation. When inserting the tool, take care that the dust protection cap 3 is not damaged.

A damaged dust protection cap should be changed immediately. We recommend having this carried out by an after-sales service.

Inserting SDS-plus Drilling Tools

The SDS drill chuck allows for simple and convenient changing of drilling tools without the use of additional tools.

Clean and lightly grease the shank end of the tool. Insert the tool in a twisting manner into the tool holder until it latches itself.

Check the latching by pulling the tool.

As a requirement of the system, the SDS drilling tool can move freely. This causes a certain radial run-out at no-load, which has no effect on the accuracy of the drill hole, as the drill bit centres itself upon drilling.

Removing SDS Drilling Tools

Push back the locking sleeve 4 and remove the tool.

3.3.- Carrying Handle (HD15K / HD17K)

The carrying handle 13 can be turned to any position. Loosen the knurled nut 14, turn the carrying handle 13 around the machine axis to the desired position and tighten the knurled nut 14 again.

The carrying handle 13 can also be mounted facing to the other side. Completely unscrew the knurled nut 14 and then pull out the hexagon bolt upward. Pull off the carrying handle 13 to the side and tilt the remaining clamping element by 180^ . Mount the carrying handle 13 in reverse order.

3.4.- Changing the Tool (HD15K / HD17K/ MH2K / MH6K / MH8K)

Before any work on the machine itself, pull the mains plug.

Clean the tool shank 16 and apply a light coat of grease.

Pull out the lock bolt 15 and turn it 180^ in anticlockwise direction. Allow the lock bolt 15 to latch again.

Insert the tool into the tool holder to the stop. The groove of the tool shank 16 must face upward as shown in the figure.

Check the latching by pulling the tool.

4.-. Operation

4.1.-Starting Operation

Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230V can also be operated with 220V .

Setting the Operating Mode

With the selector switch for drilling/hammer drilling 9, the operating mode of the machine is selected. To change the operating mode, press the release button 8 and turn the drilling/hammer drilling selector switch 9 to the desired position until it can be heard to latch.

Note: Only change the mode of operation while disconnected from the machine! Otherwise you may damage the machine.

Position for hammer

HD5K, HD5BK, MH6K: 8'

Position for drilling without impact in wood, metal, ceramic and plastic as well as for screwdriving and thread cutting.

Position for adjustment of the chiseling position

Position for chiselling HD5K, HD5BK, MH6K: 8'

Reposition Chiseling Vario-lock (HD9CK)

The chisel 12 may be positioned at angles. Thus, the optimal working position can be set for each application.

Insert the chisel in the tool holder

• Push the ring 18 forward and turn the chisel in the desired position.
• Release the ring 18 to lock the position.

Reversing the Rotational Direction

The rotational direction switch 5 is used to reverse the rotational direction of the machine. However, this is not possible with the On/Off switch 7 actuated.

Right rotation: Turn the selector switch for drilling/hammer drilling 5 on both sides to the stop in the position
Left rotation: Turn the selector switch for drilling/hammer drilling 5 on both sides to the stop in the position

Set the direction of rotation for hammer drilling, drilling and chiselling always to right rotation.

Switching On and Off

To start the machine, press the On/Off switch 7. To lock the On/Off switch, keep it pressed and additionally push the lock-on button 6.

To switch off the machine, release the On/Off switch 7. When the On/Off switch 7 is locked, press it first and then release it.

Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be variably adjusted, depending on how far the On/Off switch 7/10 is pressed.

Light pressure on the On/Off switch 7/10 results in low speed/impact rate. Further pressure on the switch increases the speed/impact rate.

Safety Clutch

If the tool insert becomes caught or jammed, the drive to the drill spindle is interrupted. Because of the forces that occur, always hold the power tool firmly with both hands and provide for a secure stance.

If the power tool jams, switch the machine off and loosen the tool insert. When switching the machine on with the drilling tool jammed, high reaction torques can occur.

Changing the Chiselling Position

The chisel SDS can be locked in different positions. In this manner, the optimum working position can be set for each application.

Insert the chisel into the tool holder.

Turn the mode selector switch 8

Turn the tool holder to the desired chiselling position.

Turn the mode selector switch 8 to the "chiseling" position. The tool holder is now locked.

For chiselling, set the rotation direction to right rotation.

Switching On/Off: A

To start the machine, press the On/Off switch 6 and keep it depressed.

To switch off the machine, release the On/Off switch 6.

Switching On/Off: B

To start the machine, press the On/Off switch 6/7 at the top (I) until it locks.

To switch off the machine, press the On/Off switch 6/7 at the bottom (O) and release it.

For low temperatures, the power tool reaches the full hammer/impact capacity only after a certain time.

Setting the Speed/Impact Rate

The electronic control 10 enables stepless speed and impact preselection in accordance with the material to be worked.

The maximum hammering capacity is achieved when the thumbwheel 10 is set to position "6". (HD50K) For lower speed settings, the hammering capacity is lower due to technical reasons.

Operation HD15K / HD17K

4.3. - Starting Operation

Observe correct mains voltage! The voltage of the power source must agree with the voltage specified on the nameplate of the machine. Power tools marked with 230V can also be operated with 220V.

Switching On and Off

To start the machine, push the On/Off switch 6/7 to the "I" position.

To switch off the machine, push the On/Off switch 6/7 to the "O" position.

For low temperatures, the machine reaches the full impact rate only after a certain time.

This start-up time can be shortened by striking the chisel in the machine against the floor one time.

4.4.- Operating Instructions

While working, hold the power tool with both hands by the handle 1.

For the highest possible impact damping, work only with moderate pressure.

5.- Maintenance and Service

5.1.- Maintenance and Cleaning

Before any work on the machine itself, pull the mains plug.
For safe and proper working, always keep the machine and ventilation slots clean.
A damaged dust protection cap should be changed immediately. We recommend having this carried out by an after-sales service.

Clean the tool holder 2 each time after using.

WARNING! Important instructions for connecting a new 3-pin plug to the 2-wire cable.

The wires in the cable are coloured according to the following code:

Do not connect the blue or brown wire to the earth terminal of the plug.

Important: If for any reason the moulded plug is removed from the cable of this power tool, it must be disposed of safely.

When the carbon brushes wear below acceptable matically service tolerances, the machine will auto cut to customer out. The machine must be sent service for address, see the maintenance for "Service and Customer Assistance" section.

Sharpening Chisels

Good results are only achieved with sharp chisels; therefore, sharpen the chiselling tools in good time. This ensures a long service life of the tools and good working performance.

Re-sharpening

Sharpen chiselling tools using grinding wheels (e.g.ceramic bonded corundum wheel) with a steady supply of water. Reference values are shown in the figure. Take care that no annealing coloration appears on the cutting edges; this impairs the hardness of the chiselling tools.

For forging, heat the chisel to between 850^ and 1050^ (bright red to yellow).

For hardening, heat the chisel to approx. 900^ and quench in oil. Then anneal in an oven for approx. one hour at 320^ (annealing colour = light blue).

If the machine should fail despite the care taken in man edures, repair ufacturing and testing proc should be carried out by an after-sales service centre for Stayer power tools.

In all correspondence and spare parts order, please always include the article number given on the type plate of the machine.

5.2.- Disposal

The machine, accessories and packaging should be sorted for environmental-friendly recycling.

Only for EC countries:

Do not dispose of power tools into household waste! According the European Guideline 2002/96/EC for Waste Electrical and Electronic Equipment and its implemen-tation into national right,

power tools that are no longer usable must be collected separately and disposed of in an environmentally correct manner.

Subject to change without notice.
