Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened. Should any of the screws be
loose, retighten them immediately. Failure to do so could result in serious hazard.
Maintenance of the motor
The motor unit winding is the very "heart" of the power tool. Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
- For safe and proper working, always keep the machine and ventilation slots clean.
- Periodically blow out all air passages with dry compressed air.
Dressing the diamond blades
If a lot of sparks are seen during cutting operation, it means that the blades are becoming dull.
To sharpen the blades, make several cuts in a special sharpening stone for diamond blades or alternately use
calcareous sandstone.
Inspecting the carbon brushes (Fig 7 & 8)
The Motor employs carbon brushes which are consumable parts. When they become worn to or near the "wear
limit", it could result in motor trouble. The power tool must then be sent to an after-sales service agent.
When you have to replacement the carbon brushes by yourself, please following the order:
- Untight and remove the seven screws M4, then remove the 2 parts of the carbon brush cover (7). There will still
be wires connected to the carbon brush cover, so be careful to jot stress them.
- Loosen and remove the carbon brushes.
- Replace the carbon brushes; be very careful not to allow the lead wire to contact the armature or rotating parts of
the motor.
- Replace the carbon brush cover (7), while being careful to ensure it does not pinch the lead wire, and secure it
firmly with the seven screws.
CAUTION:
- Should the lead wire be pinched by the main handle cover or come in contact with the armature or rotating parts
of the motor, a serious danger of electric shock to the operator will be created. Exercise extreme caution in
disassembling and reassembling the motor, following the above procedures exactly.
- Do not attempt to disassemble any parts other than those necessary to effect replacement of the carbon brush.
- Repair, modification and inspection must be must be carried out by a LEMAN Authorized Service Center.
In the operation and maintenance of power tools, the safety regulations and standards prescribed in each country
must be observed.
Do not dispose of electric tools together with household waste material!
In observance of European Directive on waste electrical and electronic equipment and its
implementation in accordance with national law, electric tools that have reached the end of their life
must be collected separately and returned to an environmentally compatible recycling facility.
