Guidelines for using circular saws
Warning! Make sure that the permitted circular saw speed is equal to or higher than the mitre saw speed. Use of a circular saw
which does not meet the above conditions will cause the circular saw to fall apart during operation, which can cause serious injury.
The circular saw must be selected according to the workpiece. The higher the number of teeth, the higher the quality of the cut, it
is recommended to use a disc with 48 teeth to cut laminated boards and hard material. If the workpiece contains staples, nails or
other structural elements, circular saws intended for cutting structural timber should be used.
Only discs recommended by the manufacturer should be used: discs for cutting wood and wood-based materials with teeth made
of carbide meeting the requirements of the EN 847-1 standard with the parameters specifi ed in the technical data table. Make sure
that the speed indicated on the disc is greater than or equal to the speed indicated on the tool.
Do not use damaged cutting discs. Before commencing any work, the cutting disc must be inspected and, in the event of cracks,
chips, bends, broken teeth or any other damage, the disc must be replaced with a new one. Hold the disc by the fi xing hole and
lightly hit the disc body with a plastic handle screwdriver. Hollow sound can mean a crack in the disc body, which may not be
visible to the naked eye.
Extension cords
If it is necessary to connect the product using extension cords, the cross-section of the extension cords should not be smaller than
the cross-section of the power cord supplied with the product. In the case of extension cords longer than 25 m, the cross-section
of the conductors should not be less than 1.5 mm .

Residual risks
The machine has been designed and built according to good construction practices and safety principles. However, there may be
residual risks when using the product.
Health hazard related to the electric power supply due to the use of improper power cords.
Noise hazard related to failure to use hearing protection.
Residual risks can be minimised by strictly following the safety instructions.
MITRE SAW OPERATION
Lifting and locking the cutting head
Out of the box, the mitre saw cutting head is locked in its lower position. To unlock it, the locking pin must be pulled out (IX). In this
locking pin position, the cutting head can be raised and lowered freely. The spring will lift the head, but do not let go of the handle
and hold it with little resistance until the head is fully lifted.
If it is not possible to lower the head to the end of the range or if the head is lowered too far, adjust it with a screw and then lock
it with the nut (X).
When lifting and lowering the cutting head, check that the movable disc guard moves freely, exposing the circular saw while
lowering the cutting head, and automatically shields the circular saw when the cutting head is lifted. If obstructions blocking the
movement of the guard are detected, they must be removed before starting work.
Setting the longitudinal cutting (bevel) angle of the cutting head
It is possible to rotate the head in the range of +/- 45 degrees. To rotate the head, loosen the locking screw, lift and hold the
locking lever and rotate the table to the desired angle (XI). Use the scale attached to the table base to facilitate setting the head
angle (XII). The latch allows easy positioning of the head at the most common angles of longitudinal cutting (0; 15; 22.5; 31.6; 45
degrees). To do this, release the pressure on the locking lever so that it is placed in the notch on the underside of the base of the
work table, and then tighten the locking screw. Other cutting angles can only be set by tightening the locking screw.
Caution! It is forbidden to lock the table only with the lever, always tighten the locking screw.
Setting the cross-cutting (bevel) angle of the cutting head.
It is possible to tilt the cutting head by an angle not exceeding 45 degrees. Unlock the head by turning the lever (XIII), then set it
at the desired angle and secure in this position by tightening the lever. When setting up, you can use the scale on the table base.
Caution! After changing the angle of the cutting head, make sure that the circular saw or the cutting head does not come into
contact with obstacles during operation. Check whether the full range of the mitre saw operation can be used, without switching
the tool on. If necessary, make the required adjustments by removing obstacles.
If it is not possible to use the full range of the cutting angle or if it exceeds the nominal values, adjustment should be made by
unscrewing or tightening the retaining screw at one and/or the other end of the scale (XIV). After setting the full range, secure the
bolts against loosening by tightening the lock nuts.
Using the dust extraction
The mitre saw is equipped with a spigot which allows the connection of a bag supplied with the mitre saw or an external dust
