MAINTENANCE
CAUTION
: Before any adjustment, repair, maintenance work and before replacing the blade,
switch off the machine and disconnect it from the power supply by removing the plug from the
socket.
In case you find out any damage to the protection devices or irregularities while processing or
checking the machine, you must get it repaired immediately by qualified persons.
Before use check that the protection and safety devices are perfectly efficient. After carrying out
the work, make a general cleaning of the machine by removing dust and chips.
DO NOT USE COMPRESSED AIR JETS TO CLEAN THE MACHINE!
In case of intensive use of the machine, you should periodically carry out some tasks:
1- Daily
Suck up the saw dust that can pile up inside the machine and clean the ventilation inlets of the
engine.
In case of use, empty the dust bag and clean it.
Be sure that the protective cap can slide freely.
Be sure that the saw blade can be raised and lowered freely.
2. Weekly
Check the saw blade brake time, and if it is longer than 10 seconds take the machine to an after
sales service.
Check that the arm’s spring allows the arm to rise up to the mechanical stop within 2 seconds.
3. Monthly
Check the noise of the engine and the consumption of the carbon brushes periodically.
Check that the supply cable is not damaged
CHECK AND REPLACEMENT OF CARBON BRUSHES
CAUTION:
Before checking the carbon brushes, disconnect the machine from the power
supply.
The life of the carbon brushes can vary, and it depends on the motor working load. If the tool is
new or after the replacement of the carbon brushes, check the carbon brushes after the first 50
hours of use. After the first check, you must control the carbon brushes every 10 hours of use
until it is necessary to replace them.
The housing of the carbon brushes
(Fig.15)
are positioned on each side of the motor. Change
both the carbon brushes if the carbon of one of the brushes is worn and it is smaller than 5 mm,
or in case a spring or a wire is burnt or damaged. If the carbon brushes are still usable after the
inspection, re-assemble them on their original position.
