and inspection operations.
Declared total value of vibration was measured by means of standardized test method and can be used to compare one tool with
the other. Declared total value of vibration can be used in the initial exposure assessment.
Note! Emission of vibration when working with the tool may vary from the declared value, depending on how the tool is used.
Note! It is required to determine safety measures to protect the operator, which are based on the exposure assessment in real
conditions of use (including all elements of work cycle, such as for example time when tool is switched off or idling and time of
activation).
MAINTENANCE AND CHECKS
Lubrication
Always before using drill bits or chisels, clean them and apply a thin layer of grease onto the tool chuck.
Oil refi lling (V)
The hammer drill mechanism is lubricated by means of an oil bath. At the bottom of the housing there is an oil fi ller with an inspec-
tion glass. If the hammer is set with the tool chuck pointing upwards and the oil in the inspection glass is not visible, it should be
refi lled. Oil level should be approx. 3 mm measured from the lower edge of the inspection glass. It is recommended to use SAE
20W-50 viscosity class engine oil .
Oil refi lling should be carried out as follows. Unplug the power cord plug from a mains socket. Turn the hammer so that the oil
fi ller is directed upwards. Unscrew the fi ller plug with inspection glass. Take precaution measures not to lose or damage the rubber
seal under the plug.
Refi ll the oil and screw the fi ller plug. Tighten the plug with suffi cient force required to obtain tightness. Excessive force may dam-
age the sealing or the threaded connection of the plug. Check the oil level before the start of work.
Oil should be refi lled every 20 days of operation, assuming that the hammer works for about 3-4 hours per day.
ATTENTION! Before any adjustment, technical service or maintenance operations unplug the tool. Once the operations have been
fi nished, 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 defl ection, 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.
