The power cord of the tool is equipped with an RCD. The RCD has a light and two buttons described: TEST and RESET. Test
RCD operation each time the tool power cord plug is plugged in. To do this, press the TEST button, the indicator light marked ON
will go on. The RCD will interrupt the power supply to the tool. Then press the RESET button to restore power supply to the tool.
Where extension cords are used, the cross-section of the cores of each extension cord shall not be less than 4 mm and the
2
sum of the lengths of the extension cords shall not exceed 30 m. If a reel extension cord is used, it must be fully unwound before
starting work.
Working with the cutter
Before cutting, mark the cutting line on the cut material. The cutter can only cut in a straight line, perpendicular to the surface on
which the tool will be led.
Wear personal protective equipment suitable to working conditions. Always wear protective goggles, protective footwear with an
anti-slip sole, a protective stand with long sleeves and legs. Hearing and respiratory protection. Use a safety helmet if necessary
Make sure you carry out all preparatory work.
Warning! When cutting wet, make sure that the water does not come into contact with live components. In particular, water must
not enter the ventilation holes or be present on the handles. Make sure that water does not fl ow down the power cord towards the
mains outlet. Contact of water with live components may cause electric shock.
Grasp the saw with both hands by the main and additional handles (X). Make sure that the cutting disc does not come into contact
with any object.
Turn the cutter on by pressing the switch.
After pressing the switch, allow the cutting disc to reach the rated speed and only then start cutting. It is forbidden to fi rst apply
the disc to the workpiece and then start the tool. This can jam or damage the disc or cause damage to the workpiece. This can
lead to serious injuries.
When resuming cutting, let the disc reach its rated speed and then insert it into the cutting slot.
When cutting, the disc should be lowered with a smooth motion, avoiding excessive pressure. The pressure to be exerted on the
tool should not be greater than that which is suffi cient to cut the workpiece. Avoid hitting the workpiece with the disc.
No parts of the body (XV) should be in the rotation plane of the cutting disc. This will reduce the risk of injury if the disc falls apart
during operation.
The disc should be led in a straight line by moving it back and forth (XVI). Do not tilt the disc from the plane of its rotation during cut-
ting. Cutting discs are not suitable for carrying lateral loads and may fall apart during operation. This poses a threat of serious injury.
Do not exert excessive pressure on the disc. Pressure on the disc should allow effi cient operation with the cutting edge.
Do not reach too far, the position of the body during operation should always allow you to control the tool, even in the case of
unexpected movement of the tool. When applying the rotating disc to the material, prepare for a jerk towards the front of the tool,
which will cause the edge of the disc to come into contact with the material being cut (XVII).
Do not lean over the product during operation, especially if the guard has been set in such a position that it does not protect the
upper part of the disc.
Wherever possible, use water cooling when cutting. Pressure of the water supply system of the product must be within the range
given in the technical data table The water system must be equipped with a separate valve enabling the water supply to the
product to be cut off .
If water does not come out of the product or comes out from a place other than the inside of the cutting disc guard, this indicates
a malfunction and the operation of the product should be stopped, and then the water system should be checked for choking and
tightness.
If water cooling is not used during operation, secure the hose and connection so that it does not come into contact with the disc
and does not interfere with the operation of the product during operation.
Always attach the objects to be cut properly to prevent unexpected movement during cutting. Refer to the information in the sec-
tion "Safety warnings related to cuttings discs".
Pipes should be cut by guiding the disc along the circumference, not through the cross-section of the pipe.
Secure the pipes with wedges during cutting. Make sure the ground on which the pipe rests is not crushed during operation.
Diamond discs can be dulled during operation. If the disc becomes less effi cient, sharpen the disc. To do this, cut the abrasive
material, e.g. sandstone, asphalt or aerated concrete.
Take special care when you stop cutting. The cutting disc loses support in the cut material, which may result in jerking or kickback
towards the operator. Relieve the pressure on the disc when you stop cutting.
If water cooling has been used during cutting, dry the disc and the inside of the disc guard. After cutting, start the disc at full speed
for approx. 30 seconds, the air momentum will dry the disc and the inside of the disc guard.
