Installation / regulation
Before execution of any procedures, disconnect
air tool from compressor.
Do not draw up the fastening elements
too tight to avoid damaging the thread.
Installing / removing the socket wrench (see fig. 1)
• When mounting, install socket wrench 8 onto the
tool holder 1, as shown in figure 1.
• Disassembly operations do in reverse sequence.
Connecting to the compressor (see fig. 2-3)
Note: make sure that the air pressure is
not less than that one specified in the
table "Air tool specification", otherwise
the air tool will work with less efficiency.
To protect the air tool against damage,
contamination and corrosion, the sup-
plied compressed air should be puri-
fied from foreign particles and mois-
ture. It is recommended to use special devices (filters,
dehumidifiers or specific air preparation units).
• Wind thread seal tape 9 (to ensure tightness of the
connection) around threaded end of quick-removable
connector 6 (see fig. 2.1).
Meaning
Useful information�
Do not dispose of the air
tool in a domestic waste
container�
• Screw in quick-removable connector 6 into inlet
connector 3 (see fig. 2.2). When screwing in quick-
removable connector 6, it is recommended to hold inlet
connector 3 using an open-ended spanner�
• Connect the air hose with the quick-removable
adapter to quick-removable connector 6 (see fig. 3).
Make sure that the air hose is securely fixed on quick-
removable connector 6 (the quick-removable adapter
on the air hose should snap)�
Initial operation of the air tool
• Check before each using of the tightness of all

Design features of the air tool
Changing the rotational directions and torque
value (see fig. 4)
Move combination switch 4 only after a
complete stop of rotating parts of the air
tool.
Clockwise rotation - move combination switch 4 as
shown in figures 4.1. By rotating combination switch 4,
you also select the torque value (the torque steps are
indicated with digits on the air tool body)�
Counter clockwise rotation - move combination
switch 4 as shown in figures 4.2. By rotating
combination switch 4, you also select the torque value
(the torque steps are indicated with digits on the air
tool body)�
Recommendations
operation
Sometimes, after the long idle time, the
air tool may not turn on, in this case it
is necessary to turn off the air supply
and manually rotate tool holder 1 that
holds accessories several times, and after that re-
enable the air tool.
• Connect the air tool to the compressor as described
above�
• Select the rotation direction as well as the
torque value by using combination switch 4� You
can choose the torque value by practical testing.
After screwing, it is recommended to check the
