Operation
Initial Operation
The air impact wrench is fitted with an R ½” compressed air connection (5). For
your own safety, do not mount firmly impact wrench and compressed-air hose,
but use a quick connector (6).
1. Put the included quick connector into the compressed-air connection (5) and
seal it up with Teflon tape.
2. Then put the socket on the anvil shank
(1).
3. Turning the flow regulator (4), you can
regulate the air intake without steps. In this way, you regulate the torque,
which abuts on the socket.
4. Please connect the unit and the compressed-air source by using a flexible air
hose.
Air Pressure and Air Quantity
The impact wrench needs a pressure of 90 psi (6.3 bars) and a compressor with
an air volume of min. 300 l/min. Utilize only connection hoses with a minimum
inner diameter of 9 mm. Setting the air pressure, please remind that the pressure
sinks about ca. 0.6 bar at a hose length of 10 m and an inner diameter of 9 mm.
Turning the Direction of Movement
The unit is designed to clockwise and counter-clockwise
rotation. The reverse valve lever (3) is located on the
reverse side of the unit.
1. If the lever is in position R, the impact wrench ro-
tates clockwise.
2. In position L, the impact wrench rotates counter-
clockwise.
