Place the socket head wrench on the nut or bolt head.
Press the switch and hold it in the position which corresponds to the required direction of rotation. (IV)
In case an element is to be tightened, press and hold the switch at the position F, while in case of undoing elements hold it in the
position R.
In case an element is to be tightened, once the maximum torque has been reached the overload coupling will be activated and the
drive power transmission system will be turned off. Then release the switch and wait until the rotation of the motor has stopped.
In case elements are to be undone, make sure the torque at which the nut was tightened does not exceed the maximum torque for
the wrench. In such case the overload coupling will also be activated, and it may turn out to be impossible to undo the nut.
Once the element has been undone, release the switch of the tool and wait until the rotation of the motor has stopped.
Once work has been concluded disconnect the tool from the mains and realise maintenance activities.
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.
