Screwdriver bit / magnetic holder (see fig. 7)

When  using  the  power  tool  as  a  screwdriver,  use 

magnetic holder 

14

  for  reliable  locking  of  screwdriver

bits 

15

 (see fig. 7). A magnetic holder 

14

 is not needed 

for  extended  screwdriver  bits 

15

 (specially purposed 

for screwdrivers).

Initial operating

of the power tool

Always  use  the  correct  supply  voltage:  the  power 

supply voltage must match the information quoted on 

the power tool identification plate.

Switching the power

tool on / off

[BM-110 T, BM-280 T]
Make sure that the reverse switch 5 is not centred; 

this blocks on / off switch 6.
Switching on: 

Press on / off switch 

6

.

Switching off: 

Release  the on / off switch 

6

.

[BM-300, BM-400, BM-400 C, BM-600, BM-600 C]
Short-term switching on / off

To switch on, press and hold on / off switch 

6

, to switch 

off - release it.

Long-term switching on / off 
Switching on: 

Push on / off switch 

6

 and lock it in the position with 

locking button for on / off switch 

9

.

Switching off: 

Push and release on / off switch

Design features 

of the power tool

Torque regulator
[BM-110 T, BM-280 T]

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 

regulator 

2 

into the position "Drill" to perform 

drilling.

Step speed selector switch 
[BM-110 T, BM-280 T]

Attention: one can only change the 

revolutions per minute range after the 

engine fully stops.

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

3

forward. 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 diameter holes.

Stepless speed adjustment

Speed  is  controlled  from  0  to  maximum  by 

pressing force of on / off switch 

6

. Weak 

pressing  results  in  low  revolutions,  which 

enable a smooth power tool switch-on.

Speed selector thumbwheel
[BM-400, BM-400 C, BM-600, BM-600 C]

Use speed control 

12

 to set required number of 

revolutions.

•

Push on / off switch 

6

 and lock it in the position with 

locking button for on / off switch 

9

.

•

Set the needed speed.

The required speed is dependent on the material and 

can be determined with practical trials.

When operating your power tool at a low speed for a 

long time, it has to be cooled down for 3 minutes. To 

do it, set a maximum speed and leave your power tool 

to run idle.

Changing the rotational directions (see fig. 8)

Change the direction of rotation only after 

a full stop of the motor, acting otherwise 

may cause damage to the power tool.

[BM-300, BM-400, BM-400 C, BM-600, BM-600 C]
Rotation to the right (drilling, screwing in)

  -  move 

the rotational direction switch 

5

 to the right.

Rotation to the left (unscrewing)

  -  move  the 

rotational direction switch 

5

 to the left.

[BM-110 T, BM-280 T]
Clockwise rotation (drilling, fastening of screws)

 - 

move the rotational direction switch 

5

 to the left as it is 

shown in fig. 8.

Counter clockwise rotation (unscrewing the 

screws)

 - move the rotational direction switch 

5

 to the 

right as it is shown in fig. 8.

Spindle automatic locking
[BM-110 T, BM-280 T]

If the on / off switch 

6

 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
[BM-280 T]

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 

6

,  the  LED 

7

operates in a mode of light (strong light)  it allows you 

to work in low light conditions.
