Attention! It is required to determine safety means to protect the operator, which are based on assessment of exposure under
real operating conditions (including the whole working cycle, as for example the time when the tool is of or idling, and the time of
activation).
Lubrication
Before each use of drills or cutters they must be thoroughly cleaned and the SDS maxchuck must be lubricated with a thin layer of
grease. It is recommended to use grease designed for the SDS maxchucks. In case of incorrect operation of the hammer action
mechanism, one of the reasons may be incorrect lubrication of the gear and the crank assembly of the hammer action piston. It
is recommended to use grease designed for toothed and crank gears. It is recommended to have grease refi lled in an authorised
service point.
MAINTENANCE AND OVERHAUL
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.
