Mounting / dismounting of the keyless chuck (see 

fig. 2-3)

•

To mount the keyless chuck 

1

, carry out the op-

erations in consecutive stages as it is shown in 

figure 2.

•

To dismount the keyless chuck 

1

, carry out the oper-

ations in consecutive stages as it is shown in figure 3.

Attention:  keep  in  mind  that  in  the  pro-

cess  of  mounting  /  dismounting  of  the 

drill  chuck  the  screw  8  has  a  left-hand 

thread.

Screwdriver bit / magnetic holder (see fig. 4)

When using the power tool as a screwdriver, use 
magnetic holder 

9

 for reliable locking of screwdriver 

bits 

10

 (see fig. 4). A magnetic holder 

9

 is not needed 

for extended screwdriver bits 

10

 (specially purposed 

for screwdrivers)�

Initial operating of the power tool

Always use the correct supply voltage: the power sup-
ply voltage must match the information quoted on the 

power tool identification plate.

Switching the power tool on / off

Make sure that the reverse switch 5 is not centred; 

this blocks on / off switch 4.
Switching on: 

Press on / off switch 

4

�

Switching off: 

Release the on / off switch

Design features of the power tool

Torque regulator

Rotate the regulator 

2

 in order to set one of 

the 18 torque values most suitable for the work 

performed�

It is recommended to set the torque regula-
tor 

2 

into the position "Drill" to perform drill-

ing�

Step speed selector switch 

Attention: one can only change the revo-

lutions per minute range after the engine 

fully stops.

In order to put in the first gear, move the switch 

3

 for-

ward� This mode is used for the fastening of screws or 
for large diameter hole drilling�

In order to put in the second gear, move the switch 

3

back� This mode is used for speed drilling of small di-
ameter holes�

Stepless speed adjustment

Speed is controlled from 0 to maximum by 
pressing force of on / off switch 

4

� Weak 

pressing results in low revolutions, which 
enable a smooth power tool switch-on�

Changing the rotational directions (see fig. 5)

Change  the  direction  of  rotation  only 

after a full stop of the motor, acting oth-

erwise  may  cause  damage  to  the  power 

tool.

Clockwise rotation (drilling, fastening of screws)

 - 

move the rotational direction switch 

5

 to the left as it is 

shown in fig. 5.

Counter  clockwise  rotation  (unscrewing  the 

screws)

 - move the rotational direction switch 

5

 to the 

right as it is shown in fig. 5.

Spindle automatic locking

If the on / off switch 

4

 is not pressed, the spindle of the 

power tool is locked this enables to use the power tool 
as an ordinary screwdriver (for example it can be used 
to tighten manually screws or bolts)�

Light-emitting diode

When the power tool is connected to the mains, the 
LED 

7

 operates in an indicator mode (low light) and 

shows that the power tool is ready to be turned on�
When you press the on / off switch 

4

, the LED 

7

 oper-

ates in a mode of light (strong light) it allows you to 
work in low light conditions�

Recommendations  on  the  power  tool 

operation

Drilling (see fig. 6-10)

•

Grease the drill bit regularly when drilling holes in met-

als (except drilling non-ferrous metals and their alloys)�

•

When drilling hard metals, apply more force to the 

power tool and lower the rotation speed�

•

When drilling large diameter holes in metal, first drill 

a hole with a smaller diameter and ream it till the nec-

essary diameter (see. fig. 6).

•

In order to avoid splitting of the surface at an exit 

point of a drill bit when drilling holes in wood, follow the 

instructions shown in figure 7.

•

In order to decrease dust production when drilling 

holes in walls and ceilings, take actions indicated in 

fig. 8-9.

•

When drilling holes in glazed ceramic tiles, in order 

to improve the drill centering accuracy and to save 
the glaze from damage, apply adhesive tape to the 

presumed hole center and drill after that (see fig. 10). 

Start drilling at lower speed increasing it as the hole 
deepens�

Screwing the screws (see fig. 11)

•

To make fastening of screws easier and in order to 

prevent  cracking  of  the  work  pieces,  first  drill  a  hole 

with a diameter equal to 2/3 of a diameter of the screw�
