OPERATION / SETTINGS

SWITCHING ON / SWITCHING OFF

The mains voltage must match the voltage on the label of the drill.

Switching on – press the switch button (6) and hold in this position.

Switching off – release pressure on the switch (6).

Locking the switch (continuous operation)
Switching on:

 • Press the switch button (6) and hold in this position.

 • Press the switch lock button (3) (fig. A).

 • Release pressure on the switch button (6).

Switching off:

 • Press and release the switch button (6).

Range of rotational speed of the spindle is controlled with 

pressure on the switch button.

WHEEL FOR SPINDLE SPEED ADJUSTMENT

The drill allows for operation with different spindle speeds. It can 

be controlled with the wheel (5) (fig. A). For each setting of the 

wheel for speed control, the speed can be adjusted continuously by 

increasing or decreasing pressure on the switch button (6).

 • Increase the speed by turning the wheel (5) clockwise.
 • Reduce the speed by turning the wheel (5) counter clockwise.

* Refer to graphic symbols on the wheel for rotational speed control or the switch.

Choose proper rotational speed when the drill operates with no 

load, with pressed switch lock button. Defined speed may decrease 

under load.
LEFT – RIGHT DIRECTION OF ROTATION
Choose direction of spindle rotation with the selector switch (4) (fig. A).
Clockwise rotation – set the switch (4) to the extreme left position.
Counter clockwise rotation – set the switch (4) to the extreme right 

position.

* In certain cases position of the direction selector switch relating to rotation direction may be different 

than specified. Please refer to graphic signs placed on the switch or tool body.

Do not change direction of rotation when the spindle of the drill 

is rotating. Ensure the position of the direction selector switch is 

correct before starting the tool.

OPERATION MODE SWITCH
Operation mode switch (2) allows for choosing suitable work mode: 

drilling with or without impact (fig. B). Set the operation mode 

switch in the position for drilling without impact (drill symbol), 

when processing materials like metal, wood, ceramics, plastics and 

alike. Set the operation mode switch in the position for drilling with 

impact (hammer symbol), when processing materials like stone, 

concrete, brick and alike. Holes in wood, wood based materials and 

metals can be made with drills of high speed steel or carbon steel 

(the latter for wood and wood based materials only). For impact 

drilling special drills with sintered carbide inserts should be used. 

You should not use counter clockwise rotation when impact 

function is on.
Long lasting drilling at low rotational speed of the spindle 

may cause motor overheating. Provide regular breaks during 

operation or let the tool operate at maximum speed with no load 

for approximately 1–2 minutes. Do not cover holes for motor 

ventilation in the tool body. 

OPERATION AND MAINTENANCE 

Unplug the power cord from mains socket before commencing 

any activities related to installation, adjustment, repair or 

maintenance. 

MAINTENANCE AND STORAGE

 • Cleaning the device after each use is recommended.
 • Do not use water or any other liquid for cleaning.

 • Clean the tool with a dry cloth or blow through with compressed 

air at low pressure. 

 • Do not use any cleaning agents or solvents, they may damage 

plastic parts.

 • Clean ventilation holes in the motor casing regularly to prevent 

device overheating.

 • In case of power cord damage replace it with a cord with the same 

specification. Entrust the repair to a qualified specialist or return 

the tool to a service point.

 • In case of excessive commutator sparking, have the technical 

condition of carbon brushes of the motor checked by a qualified 

person.

 • Always store the tool in a dry place, beyond reach of children.

DRILL CHUCK REPLACEMENT

 • Open drill chuck (1) jaws.
 • Unscrew the drill chuck fixing screw with cross screwdriver, by 

turning it clockwise (left-hand thread).

 • Install hex key in the drill chuck (fig. D).
 • Gently tap on the free end of the hexagonal key.
 • Unscrew the drill chuck.

Installation of the drill chuck is similar to deinstallation, only the 

sequence of actions is reversed. 
REPLACEMENT OF CARBON BRUSHES

Immediately replace worn out (shorter than 5 mm), burnt or 

cracked motor carbon brushes. Always replace both carbon 

brushes at a time. Entrust replacement of carbon brushes only to 

a qualified person. Only original parts should be used.

All defects should be repaired by service workshop authorized by 

the manufacturer.

NOISE LEVEL AND VIBRATION PARAMETERS

Noise and vibration information.

Parameters of produced noise level, such as sound pressure level 

Lp

A

 and sound power level Lw

A

 with measurement uncertainty K are 

specified below in this manual, in accordance with EN 60745. 
Vibration values a

h

 and measurement uncertainty K are determined 

in accordance with EN 60745-2-1 and specified below.
Vibration level specified below in this manual was measured in 

accordance with measurement procedure defined in EN 60745-2-

1 and can be used to compare power tools. It can also be used for 

initial assessment of exposure to vibrations. 
Specified vibration level is representative for main applications 

of the power tool. Vibration level may change if the power tool is 

used for other purposes, with different working tools or will not 

be maintained properly. The abovementioned factors may lead to 

higher exposure to vibrations during whole working time.
