the bottom of the base of the working table, and then tighten the locking screw.
Attention! It is prohibited to lock the table only with the lever. It is always required to fasten the locking screw.
Setting the perpendicular cutting angle
It is possible to incline the cutting head to an angle not exceeding 45 grades. It is required to unlock the head, turning the lever
(X), and then placing it at the required angle, so as to lock it in this position, tightening the lever. During settings, it is possible to
use the scale at the bottom of the table.
Attention! Once the angle of the cutting head has been modified, make sure the circular saw or the cutting head do not hit any
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 (XI). 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 (XII)
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 movement of the head is locked additionally with the guard lock of the circular saw. In order to lift the cutting
head, it is required to hold the handles, and then press the lock of the guards of the circular saw. 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.
Before cutting very wide elements, it is required lower the head and lock it with the pin at the lower position, and then using the
guiding rails move the head in the horizontal plane.
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 (XIII).
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.
Locking and unlocking of the guiding rails (XIV)
The mitre saw permits locking of the movement of the cutting head along the guiding rails. In order to do so, it is required to tighten
the locking screw. Loosening the screw will imply a possibility of moving the cutting head along the guiding rails.
Movement on the guiding rails permits to cut materials whose width is much bigger than permitted by lifting and lowering of the
cutting head.
In case of such cutting, it is required to lock the cutting head with a pin in the lower position, unlock the movement of the guiding
rails, and then move the head along with the circular saw at the horizontal plane towards the floor.
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 (XV). 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 supports and 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 (XVI), 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 (XVII).
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.
