Bosch Power Tools

Operation

Starting Operation

The pneumatic tool operates optimally at a working pressure 
of 6.3 bar (91 psi), measured at the air inlet of the actuated 
pneumatic tool.



Pay attention to the direction of rotation that is set, be-
fore switching on the pneumatic tool. 

For example, 

when a screw is to be loosened and the direction of rota-
tion is set so that the screw is tightened, this can lead to a 
strong uncontrolled movement of the pneumatic tool.

Setting the Direction of Rotation and the Torque

The rotational direction switch 

5

 is used both for setting the 

direction of rotation as well as for setting the torque.



Operate the rotational direction switch only when the 
tool is not in use.

Right rotation:

 For screwing in bolts and nuts, turn the ro-

tational direction switch 

5

 in a clockwise direction to 1 

(lowest torque), 2, 3 or to “

R

” (highest torque).

–

Left rotation:

 For loosening or unscrewing screws and 

nuts, push the rotational direction switch 

5

 to “

L

”.

Right rotation:

 For screwing in bolts and nuts, turn the ro-

tational direction switch 

5

 in a clockwise direction to 1 

(lowest torque), 2 or to the stop to 3 (highest torque).

–

Left rotation: For loosening bolts and nuts, turn the ro-
tational direction switch

5

 in an anticlockwise direction.

Left rotation: For loosening bolts and nuts, turn the ro-

Switching On and Off

Note: 

When the pneumatic tool does not start, for example af-

ter a longer rest period, disconnect the air supply, and turn 
the motor by the tool holder 

3

 several times through. This re-

moves the adhesive forces.

– To 

switch on

 the pneumatic tool, press the On/Off switch 

8

.

– To 

switch off

 the pneumatic tool, release the On/Off 

switch 

8

.

Note: 

The required torque adjustment and the duration of the 

driving-in procedure depend on the type of screw connection 
and can be best determined by practical trials. Check the trial 

screwings with an electronic torque measurer or a torque 
wrench. Once the optimal torque setting and driving-in dura-
tion are determined, you should always press the On/Off 
switch 

8

 for the same duration for the same driving-in proce-

dures.

Working Advice



Place the application tool onto the nut/screw only 
when the screwdriver is switched off. 

Rotating applica-

tion tools can slide off the nut/screw.



In case of an interruption of the air supply or reduced 
operating pressure, switch the pneumatic tool off. 

Check the operating pressure and start again when the op-
erating pressure is optimal.

Sudden loads cause a sharp drop in speed or a complete stop, 
yet do not cause damage to the motor.

Maintenance and Service

Maintenance and Cleaning



Have maintenance and repair work carried out only 
through qualified persons. 

This will ensure that the safe-

ty of the pneumatic tool is maintained.

After each service, check the speed with a speed-measuring 
device and check the pneumatic tool for increased vibrations.

An authorized Bosch after-sales service agent will carry out 
this work quickly and reliably.

Use only original Bosch spare parts.

Regular Cleaning (see figure C)

– Regularly clean the filter at the air inlet of the pneumatic 

tool. For this, unscrew the hose fitting 

15

 or tube connec-

tor 

18

 and remove dust and dirt particles from the filter. 

Then retighten the tube connector securely.

Water and debris particles in the compressed air cause rust 
and lead to wear of plates, valves etc. To prevent this, fill sev-
eral drops of engine oil into the air intake 

7

. Reconnect the 

pneumatic tool to the air supply (see “Connecting the Air Sup-
ply”, page 19) and run it for 5 – 10 seconds, while catch-
ing/picking up the escaping oil with a cloth. 

Always carry out 

this procedure when not using the pneumatic tool for a 
longer period of time.

Scheduled Maintenance

The motor plates should be checked regularly by specialised 
personnel and replaced, if required.

Lubricating the Pneumatic Tool

For direct lubrication of the pneumatic tool or admixtures to 
the service unit, use SAE 10 or SAE 20 engine oil.

Note: 

Too much grease affects the performance of the impact 

wrench because the striking mechanism sticks.

0 607 450 593 (see figure D)

An oil chamber 

20

 is installed for lubricating the com-

pressed-air motor. If an oil mister is used, it should be 
filled at least once a day using an oil pressure sprayer.

– To do so, turn the pneumatic tool so that the handle points 

upward.

“Forward” stands for right rotation.

“Reverse” stands for left rotation.

“Reverse” stands for left rotation.

“Forward” stands for right rotation.
