This manual is consistent with the date of manufacture of
your machine, you will nd information on the technical
data of the machine acquired manual check for updates
of our machines on the website: www.grupostayer.com
1. Machine-specic Safety Warnings
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 re and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line causes property
damage or may cause an electric shock.
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 rmly
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.
2. Functional Description
Read all safety warnings and all instructions. Failure to
follow the warnings and instructions may result in electric
shock, re and/or serious injury.
While reading the operating instructions, unfold the
graphics page for the machine and leave it open.

11
is positioned in the groove on the housing 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 e󰀨ect 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 (MD15K)
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 13can also be mounted facing to the
other side. Completely unscrew the knurled nut 14 and
then pull out the hexagon bolt upward. Pull o󰀨 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 (HD7BK / MD15K / MH6BK)
Before any work on th e 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
gure.
Check the latching by pulling the tool.
3.5 Changing the Tool (TD-800)
The TD-800 model allows rapid tool coupling both circular
rod. (Example: A drill HSS) and tool shank SDS-PLUS.
In either case pull the locking ring back (Fig 21) and insert
the tool.
In the case of the rst rotating circular tool clamping hand
the outside and then the key ring fastener.
With the SDS-PLUS tool simply insert thoroughly. Lock
the chuck by pulling out of the outer cylinder. (Figure 22)
4. Operation
4.1 Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specied on the nameplate of the machine.
Power tools marked with 230 V can also be
operated with 220 V.
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 drilling in concrete or stone, HD5CK,
MH6BK: 8’ (gs. 12 and 13).
Position for drilling without impact in wood, metal, ceramic
and plastic as well as for screwdriving and thread cutting.
(Figs. 14 and 15).
Position for adjustment of the chiseling position (gs. 16
and 17).
Position for chiselling, HD5CK, MH6BK: 8’ (g 18).
Reposition Chiseling Vario-lock (MD10K)
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/O󰀨 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.

ENGLISH
12
12
Set the direction of rotation for hammer drilling, drilling
and chiselling always to right rotation.
Switching On and O󰀨
To start the machine, press the On/O󰀨 switch 7.
To lock the On/O󰀨 switch, keep it pressed and additionally
push the lock-on button 6.
To switch o󰀨 the machine, release the On/O󰀨 switch 7.
When the On/O󰀨 switch 7 is locked, press it rst 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/O󰀨
switch 7/10 is pressed.
Light pressure on the On/O󰀨 switch 7/10results 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 rmly
with both hands and provide for a secure stance.
If the power tool jams, switch the machine o󰀨 and
loosen the tool insert. When switching the machine
on with the drilling tool jammed, high reaction torques
can occur.
4.2 Working Advice
Changing the Chiselling Position
The chisel SDS can be locked in di󰀨erent 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/O󰀨: A
To start the machine, press the On/O󰀨 switch 6 and keep
it depressed.
To switch o󰀨 the machine, release the On/O󰀨 switch 6.
Switching On/O󰀨: B (g. 19).
To start the machine, press the On/O󰀨 switch 6/7 at the
top ( I ) until it locks.
To switch o󰀨 the machine, press the On/O󰀨 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”.
For lower speed settings, the hammering capacity is lower
due to technical reasons.
Setting the Impact Rate HD3BE K
You can set the impact rate of the switched on power tool
continuously, depending on how far you press down the
On/O󰀨 switch 7.Slight pressure on the On/O󰀨 switch 7
causes a low impact rate. Stronger pressure increases
the impact rate.
OPERATION MD15K
4.3 Starting Operation
Observe correct mains voltage! The voltage of
the power source must agree with the voltage
specied on the nameplate of the machine.
Power tools marked with 230V can also be
operated with 220V.
Switching On and O󰀨
To start the machine, push the On/O󰀨 switch 6/7 to the “I”
position.
To switch o󰀨 the machine, push the On/O󰀨 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 oor 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:

ENGLISH
13
13
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
service tolerances, the machine will automatically cut
out. The machine must be sent to customer service for
maintenance for address, see the “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
Sharpenchisellingtools using grinding wheels(e.g.ceramic
bonded corundum wheel) with a steady supply of water.
Reference values are shown in the gure. Take care that
no annealing coloration appears on the cutting edges; this
impairs the hardness of the chiselling tools. (Fig. 20).
For forging, heat the chisel to between 850ºC and 1050°C
(bright red to yellow).
For hardening, heat the chisel to approx. 900 °C and
quench in oil. Then anneal in an oven for approx. one hour
at 320°C (annealing colour = light blue).
If the machine should fail despite the care taken in
manufacturing and testing procedures, repair 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
We recommend subjecting electric tools,
accessories and
packaging to a recovery process that
respect the environment.
Do not throw away electric tools!
For EU countries only:
In accordance with European Directive 2012/19/UE on
unserviceable electric and electronic apparatus, after
transposition into national law, electric tools must be
collected separately to subject them to ecologic recycling.
Subject to change without notice.
