being cut, as well as near the cutting line, on both sides (X). If the workpiece being cut is too small to support it, set the supports
as shown in the fi gure (XI).
TOOL OPERATION
Preparing for operation
Warning! Before starting any assembly, disassembly, or adjustment works related to the disc, make sure that the tool is turned
off , and the power cord plug is disconnected from the electric outlet.
Unpack the tool and remove all packaging components. It is recommended to maintain the packaging, as it may be useful for later
storage of the product.
First, attach the diamond cutting disc to the tool.
Unscrew the fi xing screw and remove the external fi xing fl ange (II). Make sure that the spindle, fl anges, fi xing screw and the inside
of the cover are free from contamination. If necessary, clean with an air stream at a pressure of not more than 0.3 MPa, or with a
paintbrush or a brush with soft plastic bristle.
When installing the disc, make sure that the arrows indicating the direction of rotation on the tool cover and on the disc point in the
same direction. Place the disc on the spindle (II), install the outer fi xing fl ange (III). Hold the outer fl ange with a ring wrench and
tighten the disc fi xing screw (III) fi rmly and securely with a socket wrench.
Rotate the disc several times with your hands and make sure that it does not come into contact with the inside of the cover or any
other part of the tool.
Before assembling the water nozzle, remove the cutting depth guide screw completely and lift the cutter so as to gain free access
to the nozzle mounting spot. Fix the nozzle with a screw (IV). Do not tighten the screw too much to avoid damaging the plastic
nozzle. Slide one end of the hose over the nozzle connection and slide the adapter to connect the hose to the water system on
the other (V).
The nozzle is equipped with a valve to close the water supply. The valve is closed if its lever is perpendicular to the axis of the pipe
on which it is mounted. The valve is opened when the lever is set parallel to the axis of the pipe on which it is mounted.
After mounting the nozzle, re-attach the tool to the cutting depth guide.
Setting the cutting depth (VI)
Warning! Before starting any cutting depth adjustment, make sure that the tool is turned off , and the power cord plug is discon-
nected from the electric outlet.
The cutting depth is adjusted by loosening the guide screw to set the desired cutting depth and tightening the guide screw. Check
that the base does not change its position in relation to the cutter. If necessary, tighten the guide screw.
Connecting the water system and wet cutting
Warning! Before starting any activities related to connecting the water system, make sure that the tool is turned off and the power
cord plug is disconnected from the power outlet.
Wherever possible, use wet cutting. This will reduce dust in the workplace and extend the disc life. Before starting wet cutting,
make sure that the disc used for cutting is intended for wet cutting and that the workpiece can be cut wet.
A tap connected to the municipal water supply network, a portable pump or a water tank located above the cutting spot from which
the water will fl ow due to gravity can be used as the water source. Do not use pressure washers as the water source. Excessive
water pressure can damage the hose and/or nozzle. Use only cold, clean water for cooling. Impurities may clog the hose or the
nozzle outlet, which will limit or stop the fl ow of water. Water must be supplied to the nozzle under pressure as the tool is not
equipped with any water pump. Water pressure must be adjusted experimentally using the nozzle valve. The water system must
be equipped with a separate valve enabling the water supply to the product to be cut off .
For wet cutting, prepare the workplace in such a manner that the hose is not bent, crushed or cut. Water should fl ow freely from the
workpiece being cut and should not accumulate in the workpiece or in the elements of the cutter, especially inside the disc guard.
Power supply connection
Warning! Check the condition of the power cord before each use. If any damage is detected, do not connect the power cord to the
power supply. The damaged cable must be replaced at an authorised workshop. The power cord must be equipped with an RCD.
It is forbidden to use the tool with a damaged power cord. Do not replace the power cord by yourself.
The tool's power cord is equipped with an RCD (VII). The RCD has two buttons marked: TEST and RESET. Test RCD operation
each time the tool power cord plug is plugged in. To do it, press the TEST button. 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 2 and the
