7.1 Additional handle
For safety reasons always use the additional handle [7], firmly
mounted on the clamping neck [3]� The stop bar [6] can be used to
adjust the drilling depth�
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 direction-
ally to remove the tool�
Be careful as the chuck gets hot:
In case of longer work tasks, especially in impact drill-
ing, 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 [11] the machine activates and re-
leasing the button stops it�
7.4 Permanent run
By pressing the switch button [11] to the stop and simultaneous
pressing the latching pin [12] permanent run is achieved�
Repeated pressing the switch button [11] and its release the per-
manent run is discontinued�
7.5 Speed control
By light and gradual pressing the controller button [11] 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 [10] 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 recommend-
ed to verify it�
If the machine is loaded considerably, adjust the pre-selection
wheel [10] 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 shiftiDobng
EV 13 E-2H3, EVP 13 E-2H3
Use the speed lever [8] to adjust the 2nd speed gear:
1� Speed – lower speed gear – higher torque
2� 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
EVP 13 E-2H3
Use the impact lever [4] to gear the impact up or down� The shift-
ing 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 ham-
mer symbol�
The impact drilling is recommended to be used in concrete, brick-
work and earthenware� The switch lever [9] must be always shifted
to the right run�
7.10 Removing the chuck with ring gear
Hold the spindle on the surface [2] using an open wrench (17 mm)�
Insert the chuck hook [16] 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 [16]�
7.11 Removing the quick-tightening
chuck
Clamp the hexagonal wrench [18] into the chuck� Hold the spindle
on the surface [2] using a spanner (17 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�
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 elimina-
tion in line with standard EN 55014�
Before turning the tool on, check that the information on the pro-
duction 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
– 50 m length, conductor cross section: 3 × 2�5 mm
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 regula-
tion (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
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
recommended�
Clamping device
Clamp the worked pieces properly into the screw-type clamping
