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 automat-
ically.
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 recom-
mended to wear protective gloves.
Switching on and off
By pressing the switch button (7) the machine activates and releasing
the button stops it.
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.
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.
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 dis-
connected).
After a longer work at low speed leave the machine run idle for 3 min-
utes at maximum speed to cool the engine down.
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 elec-
tronic 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
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 di-
rection 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.
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 sym-
bol.
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.
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).
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 firm-
ly clamped chuck by impacts of the hammer on the hexagonal wrench.
Proceed in reverse sequence to screw the chuck on.
Work instructions
Drill bits
For steel use perfect and sharpened drill bits made of good-quality
high-speed steel.
Drilling stands
For precise drilling on smaller parts, use of a drilling stand is recom-
mended.
Clamping device
Clamp the worked pieces properly into the screw-type clamping unit.
Thus turning of the piece is avoided, as well as a potential accident.
Drilling in tiles
Shift the impact gear lever (4) to the drill-bit symbol. Once the upper
layer is drilled through, shift the impact gear lever to the hammer sym-
bol.
Thread cutting
Clamp the screw tap properly in the chuck using a considerable power,
otherwise it will slide through.
Maintenance and service
Attention! Risk of el. shock. Prior to start any operation,
pull the plug out of the socket!
Vent holes (5) of the motor guard may not be covered.
Cable replacement must be carried out by a specialized service station
authorized correspondingly.
After ca 200 hours of operation the following activities and works
have to be carried out:
Check of brush length. The brushes shorter than 5 mm have to be re-
placed for new ones.
Grease replacement in gearbox and bearings.
Attention! With respect to protection from el. shock and
preservation of the class of protection, all maintenance
and service operations requesting jig saw case removal
must be performed by the authorized service centre only!
The current list of authorized service centres can be found at our website

Storage
Packed appliance may be stored in dry, unheated storage place with
temperature not lower than -5 °C.
Unpacked appliance should be stored only in dry storage place with
temperature not lower than +5 °C with exclusion of all sudden temper-
ature changes.
Environmental protection
Power tools, accessories and packaging should be sorted for environ-
mental-friendly recy.
Only for EU countries:
Do not dispose of power tools into household waste!
According to the European Directive 2002/96/EC on waste electrical and
electronic equipment and its incorporation into national law, power
tools that are no longer suitable for must be separately collected and
sent for recovery in an environmental-friendly manner.
