OPERATING OF THE TOOL
ATTENTION! The installation of the equipment may be done only with disconnected power supply. Disconnect the battery from
the tool!
Working with the socket impact wrenches
Before you start screwing the bolt or nut with the wrench, you should by hand screw the bolt or nut on the thread (at least two turns).
Make sure that you correctly choose the size of socket wrench for item, which is tightened or loosened. Bad selection of size may
result in damage of the key or nut or bolt.
Tightening and loosening
Install on the driver the corresponding socket (III).
Select the correct direction of rotation by pressing the switch (IV). The arrow on the switch indicates the direction of linear motion
of nut or bolt during operation.
Connect the battery to the tool.
Grasp the tool with both hands (V).
Push the socket wrench on the nut or bolt head.
Press the switch and hold it. The pressing on the switch allows you to adjust the speed of the key. The greater pressure force on
the switch, the higher the rotational speed of the key.
In the case of tightening, after reaching the maximum torque, the overload clutch engages and the driver drive is disconnected.
You should then release the switch and wait for the complete cessation of engine rotation,
When loosening, make sure that the moment, of what the nut has been tightened, does not exceed the maximum torque of
wrench. In this case the overload clutch also engages and it may not be possible to unscrew the nut.
After unscrewing you should release the pressure on the control switch and wait for the complete cessation of engine rotation.
After fi nishing work, you should disconnect the tool from mains and start maintenance.
Control panel (VI)
The tool allows electronic control via a button and LEDs. Various functions are available depending on the direction of rotation. By
setting the driver’s clockwise rotation it is possible to set slow and fast turns, and hence the corresponding smaller and larger rota-
tional element. The button should be pressed while any LEDs on the control panel are illuminated. The lighting of the upper diode
in the middle column allows you to set the idle speed and lower the torque. The lighting of the bottom diode in the middle column
allows you to set faster revolutions and higher torque. When setting the counter-clockwise rotation of the driver it is possible to
set the key in intermittent or continuous operation. Lighting up the lower diode in the middle column and the upper diode in the
right column allows intermittent operation. Only the bottom diode in the middle column lights up, it means continuous operation.
Intermittent operation is intended for loosening nuts or bolts. In this mode, pressing the switch only results in a short start of the
driver’s rotation. After this, release the pressure on the switch and press it again to start the rotation of the driver.
The left column of LEDs indicates the battery charge level. The more LEDs lit, the higher the battery charge.
Operating of the tool
The depth of switch push determines the revs speed and torque. The tool does not have option to set the preset speed and torque.
You should enter the tip in socket screw or impose on the nut, and then swithc on the device. This will prevent damage to the
fasteners or to the tip. It will also reduce the risk of injuries.
In the case of screwing bolts in the surface, it is recommended that you perform a pilot hole with a diameter of core screws. This
will prevent the destruction of the material during screwing. It is also possible to screw without a pilot hole. During both types of
screwing in you should begin with a small revs speed and possibly increase it in the course of work.
In the case of screw connections, for example, when screwing in the coated screws in threaded holes or when you screw on the
nuts on the threaded pins you should perfor the fi rst few turns by hand, key or a screwdriver. Only after ensuring the correct screw-
ing in of one element in the second, you may ready to work a screw impact wrench. In the case of screwing the threaded elements
it is not recommended to exert too much pressure on the impact wrench. This can lead to the destruction of the thread.
After tightening the elements, it will start the hammer mechanism, what will be indicated by “bumps” the revving mechanism, in
this case, you should release your pressure on the switch and cease further tightening the components. Continuing to tighten can
lead to the destruction of connecting elements.
Using attachments
The tool must not be used to power working attachments.
Additional information
During work do not exert excessive pressure on the processed material and do not make violent moves, so as to avoid any dam-
age to the working tool and the drill.
