working speed. Apply only full-speed rotating accessories to the workpiece. Do not apply excessive force, but only as much force
as is needed for proper operation. Apply sanding discs at a slight angle to the workpiece. Place the cutting discs perpendicular
to the intended cut. Brushes should be applied in such a way that the ends of the wires, not their lateral surfaces, abrade the
workpiece.
When fi nished working, move the accessory safely away from the workpiece, then switch off the power tool and wait for the in-
serted tool to come to a complete stop. Disconnect the battery from the power tool and proceed with disassembly or adjustment.
The workpiece must be clamped or supported in such a way as to prevent uncontrolled movement of the material and its parts
while being worked on. This can be done using supports, brackets, clamps, vices, etc. Clamping should be done in such a way
as to ensure free access to the work surface.
Always hold the tool with both hands by the insulated handles (V). This will make the work safer and allow easier control of the
tool, also during unexpected situations.
Hold the tool with suffi cient force to work safely. An overly fi rm grip can cause fatigue. Avoid holding the tool with your fi ngers
alone.
When using tools screwed onto a threaded shank, they should be selected so that the fi xing thread is no longer than the hole into
which it will be screwed. This will prevent the accessories from breaking. Stems with fl at fl anges and without undercuts or recesses
should be used. This will increase the contact area between the stem and the accessory and prevent breakage.
Accessories with a diameter larger than that specifi ed in this manual must not be used.
Get to work. In continuous operation, the heat build-up of the grinder and tool should be monitored and breaks should be taken
during operation as the temperature rises. To prevent the motor from overheating, it is advisable to take frequent breaks from the
grinder and keep the ventilation slots clear.
When working with the grinder, do not exert too much pressure on the workpiece and do not make sudden movements in order
not to damage the tool fi tted or the grinder itself.
When drilling or milling in steel or aluminium, tools can be cooled with emulsifying oil or coolant recommended for the specifi c
material, while the use of coolant is not recommended when working in brass. In the fi nal phase of drilling through holes, the
pressure on the drill bit should be reduced to avoid breaking or jamming. Once the drill is jammed, switch off the tool immediately.
Exerting high pressures on the tools, or a wrong choice of speed for the type of work involved, will result in overloading of the tool,
which can be recognised by signifi cant heating of the outer surfaces of the tool body.
Do not overload the tool, the temperature of the external surface must never exceed 60°C.
After fi nishing work, switch off the tool, disconnect the battery and perform maintenance and inspection.
MAINTENANCE AND INSPECTIONS
CAUTION! Before starting adjustment, maintenance or servicing, pull the tool plug out of the mains socket or disconnect the
battery from the tool. Having fi nished working, inspect the power tool for damage by visually checking the exterior and the body
and the handles. Check the power cord with plug and its rubber gland or the battery housing, the action of the electric power
switch, the ventilation openings for clogging, the motor brushes for sparking, the noise of the bearings and the drive transmission,
and how the power tool starts and runs. During the warranty period, the user is not allowed to install any power tools or replace any
components or parts, as this will void the warranty rights. Any irregularities found during the inspection or the operation signal the
need for repair to be done at the service centre. After fi nishing work, the housing, ventilation openings, switches, auxiliary handle
and covers should be cleaned e.g. with an air jet (with a pressure not exceeding 0.3 MPa), paintbrush or dry cloth without the use
of chemicals and cleaning agents. Clean the tools and the handles with a clean dry cloth.
