obstacles during work. It is required to check, without turning the tool on, whether the whole working range of the mitre saw may
be used. If necessary, it is required to realise adequate adjustments to remove obstacles.
If it is not possible to use the whole range of the cutting angle or it exceeds the nominal values, then it is required to realise adjust-
ments, loosening or tightening the lock screw at either or both ends of the scale (IX). Once the whole range has been adjusted, it
is required protect the screws from loosening, tightening the locking nuts.
Lifting and locking the cutting head (X)
Once the cutting head of the mitre saw is removed from the packaging, it is locked at the bottom position. In order to unlock it,
it is required to pull the lock pin, turn it by 90 grades and release it. At such position of the lock pin it is possible to freely lift and
lower the cutting head. The spring will lift the head, but the handle must not be released, but held with a slight resistance, until
the head is fully lifted.
In case if it is not possible to lower the head to the end of the range or if it is lowered too much, it is required to carry out adjust-
ments using the screws, and then lock it with the nut (XI).
During lifting and lowering of the cutting head, it is required to make sure the mobile guard of the disc is moving freely, uncovering
automatically the circular saw during lowering of the cutting head and automatically covering the circular saw during lifting of the
cutting head. In case the guard encounters obstacles, it is required to remove them before resuming work.
Using dust extractor
The mitre saw is equipped with a ferrule which permits connection of the bag the mitre saw is equipped with or an external dust
extraction system. In case of using the attached bag, it is required to fix it at the ferrule tightening the wire ring, which forms the
internal structure of the bag (XII). The bag must be emptied each time it is full and each time work has been concluded.
Transport of the tool
In case of transport of the mitre saw, it is required transport it in its original factory packaging. It is required to lower the cutting head
to the lowest position and secure it with a pin. Turn the table by 45 degrees in accordance with the foamed polystyrene moulded
pieces in the packaging. It is required to dismantle the working table locking screw.
Cutting with the mitre saw
Once the cutting head has been placed in the required position and the material to be cut has been fixed on the table (XIII), cut-
ting may start.
The switch is equipped with a lock which protects it from accidental activation. Pull it with the thumb, and only then press the
switch (XIV).
Once the switch has been pressed, let the circular saw reach the nominal rotation and then start cutting. It is prohibited to put the
saw at the material and then start the tool. This may cause seizure of the saw, its defects or damage to the material. This may
also cause injuries.
In case cutting is resumed, let the circular saw reach the nominal rotation and then insert it in the kerf.
During cutting the circular saw must be led with smooth movements. Avoid excessive pressure. The pressure against the cutting
head should not exceed the pressure which is sufficient to cut the material. It is required to avoid hitting with the circular saw
against the material being cut.
In case the saw is seized in the material being cut, it is required to immediately release the switch of the tool, disconnect the tool
from the power supply source, and then remove it from the kerf.
It is required to inspect the saw for defects or deformations which might have been caused by the seizure and in case any are
detected the saw must be replaced with a new one. It is also required to check the cause of the seizure, for example to make sure
there are no metal elements in the material being cut, which might cause seizure of the saw. Before work is resumed, it is required
eliminate the cause of seizure of the saw.
Once cutting has been concluded, it is required to remove the rotating saw from the kerf, and only then release the switch.
Once work has been concluded, it is required to carry out maintenance tasks.

MAINTENANCE AND INSPECTIONS

ATTENTION! Before any adjustments, technical service or maintenance actions may be realised, it is required to remove the plug
of the tool from the mains socket. Once work has been concluded, it is required to check technical conditions of the electric tool,
through visual inspection and evaluation of the body and the handles, the electric cable with the plug and the bend protector.
Check also functioning of the electric switch, make sure the ventilation slots are clean, check the sparking of the brushes, the
noise emitted during work, bearings and gears, start-up and uniformity of functioning. During the period of validity of the guarantee
the user must not dismantle the tool or replace any assemblies or parts, which would make the guarantee void. Any irregularities
