Design features of the power tool

Battery

The battery 

15

 is protected by the safety system 

against deep discharge� In case of complete discharge, 

the power tool is automatically switched off� 

Attention: 

do  not  try  to  switch  on  the  power  tool  when  the 

protection  system  is  activated  the  battery  15  can 

be damaged.
Temperature protection

The temperature protection system enables to auto-

matically deactivate the power tool in case of excess 

load or when the temperature of the battery 

15

 is ex-

ceeding 70°C� The system guarantees protection of 

the power tool from damage in case of noncompliance 

with the operation conditions�

Indicators  of  the  state  of  battery  charge  (see 

fig. 17-18)

With the push of the button 

6

 the indicators 

7

 show the 

state of charge of the battery 

15

 (see fig. 17-18).

LED lamp

When the on / off switch 

13

 is pushed, the LED lamp 

4

is automatically switched on that allows to carry out 

works in low light conditions�

Function switch (see fig. 19)
[CT21075HMX-2, CT21075HMX-4]

Switching  the  operation  modes  shall  be 

carried  out  only  in  the  off  mode  of  the 

tool's motor.

Function  switch  21  is  designed  for  the  switching 

the following operation modes of the tool:

Screwing 

(set the function switch 

21

 in the position 

indicated  in  figure  19.1)  - 

for screwing in of threaded 

fastening elements� In this operation mode, it's 

possible to set one of the 21 torque values�

Drilling

 (set the function switch 

21

 in the position 

indicated in figure 19.2) - non-impact drilling in wood, 

synthetics, metal�

Impact

drilling

 (set the function switch 

21

 in the 

position  indicated  in  figure  19.3)  -  impact  drilling  in 

masonry, concrete, natural stone�

Torque regulator

Rotate the regulator 

11

 in order to set one of 

the 21 torque values most suitable for the work 

performed� 

Attention:  for  models  CT21075HMX-2, 

CT21075HMX-4  this  function  works  in  "Screwing" 

mode only.
[CT21076HMX-2,  CT21076HMX-4,  CT21076HQX-2, 

CT21076HQX-4]

It is recommended to set the torque 

regulator 

11

 into the position "Drill" to 

perform drilling�

Stepless speed adjustment

Speed is controlled from 0 to maximum by 

pressing force of on / off switch 

13

� Weak 

pressing results in low revolutions, which 

enable a smooth power tool switch-on�

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 "1" gear, move the switch 

9

 back� 

This mode is used for the fastening of screws or for 

large diameter hole drilling�
In order to choose the "2" gear, move the switch 

9

forward� This mode is used for speed drilling of small 

diameter holes�

Changing the rotational directions (see fig. 20)

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 reverse switch 

12

 to the left as it is shown 

in fig. 20.1.

Counter  clockwise  rotation

 (unscrewing the 

screws) - move the reverse switch 

12

 to the right as it 

is shown in fig. 20.2.

Spindle automatic locking

If the on / off switch 

13

 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, if the battery is low)�
