Preparatory steps to work
Before starting the work:
Clamp the workpiece in a vise or with carpentry clamps.
Use the tools which are appropriate for the work to be done. Choose the right type of tip to the screw socket.
Wear work clothing and protection for sight and hearing.
Grasp the tool with both hands (V).
Adopt a stable stand.
Turn on the tool by finger pressing the switch.
Attention! If you notice any suspicious noise during operation, cracks, stench, etc. you should immediately turn off the tool and
remove battery pack from it.
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 first 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.
Make regular breaks during work.
Do not overstress the tool. The temperature of the external surfaces must not exceed 60 O C.
Once the work has been concluded, turn the drill off, remove the battery and carry out maintenance tasks and inspection.
MAINTENANCE AND OVERHAUL
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been
finished, the technical conditions of the tool must be assessed by means of external evaluation and inspection of the following
elements: body and handle, conductor with a plug and deflection, functioning of the electric switch, patency of ventilation slots,
sparking of brushes, noise level of functioning of bearings and gears, start-up and smoothness of operation. During the guarantee
period, the user cannot dismantle the electric tools or change any sub-assemblies or elements, since it will cancel any guarantee
rights. All irregularities detected at overhaul or during functioning of the tools are a signal to have the tool repaired at a service
shop. Once the functioning has been concluded, the casing, ventilation slots, switches, additional handle and protections must be
cleansed with a stream of air (at a pressure not exceeding 0.3 MPa), with a brush or a cloth without any chemical substances or
cleaning liquids. Tools and handles must be cleansed with a clean cloth.
