Dust suction during the power tool
operation
Dust suction allows reducing dust concen-
tration in the air and prevents its accumu-
lation at the workplace� While operating the
power tool, always use a vacuum cleaner
suitable for collecting process-generated dust� Vacuum
cleaner can be connected to the adapter 4 (a special
adapter may be required)�
Recommendations on the power tool
operation
Setting the slot depth (see fig. 9)
Before starting the work, adjust the slot depth�
• Loosen the wing screw 14 (see fig. 9).
• Set the desired cutting depth by raising or lowering
the body of the power tool� The set value of the slot
cutting depth is indicated by the pointer 24 on the
scale 15�
• Tighten the wing screw 14�
General operational recommendations (see fig. 10-13)
The performance and quality of the cut
depends on the type of the diamond cut-
ting discs, so choose them correctly de-
pending on the material being processed
and the type of work.
• Adjust the slot width and depth as described above�
• Connect the power tool to a proper dust extraction
device�
• Place the back of the base plate 16 on the surface to
be treated so that the diamond cutting discs 18 do not
touch the surface (see fig. 10.1).
• Turn on the power tool, wait until the motor reaches
its maximum speed, and gently lower the power tool
until the base plate 16 adheres to the surface to be
treated with the entire plane, then start moving the
power tool (see fig. 10.2).
• Note: cutting should always be carried out in the
direction shown in figure 11. When cutting in the op-
posite direction, there is a danger of uncontrolled ejec-
tion of the power tool from the cut towards the user,
which can lead to serious injuries�
• Do not move the power tool too quickly� It takes
time to complete the operation� Excessive force when
moving will not give the best results, but will overload
the motor of the power tool, and the diamond cutting
discs 18 will wear out faster�
• Move the power tool along the cutting line without
distorting and without making oscillatory and jerky
movements� Make sure that roller 5 rolls over the treat-
ed surface� This will facilitate the work�
• When cutting horizontal or inclined grooves, you
may make guides that are attached to the treated sur-
face� Move the power tool, resting the side surface of
the base plate 16 on the guide (see fig. 12). This will
facilitate the work�
• After making the cut, remove residual material from
the slot using the break-out tool 22 (see fig. 13).
• When making openings in the walls, make cuts
along the contour of the opening, setting the maximum
depth of the slot� Remove residual material from the
groove with a perforator� This will speed up the work,
and the contour of the opening will be smooth without
chipping�
• After the work has been completed, remove the dia-
mond cutting discs 18 from the cuts and turn off the
power tool� Wait until the diamond cutting discs 18 are
completely stopped and only then put off the power
tool�
• Turn on the power tool before the diamond cutting
disc 18 touches the workpiece� Wait until the diamond
cutting disc 18 has reached its maximum speed�
Note: the adapter for the vacuum clean-
er 4, as well as the diamond cutting
discs 18, get very hot during operation;
do not touch them until they cool down.
Special aspects of using the diamond cutting
discs
• When cutting particularly hard materials, such as
concrete with a high content of gravel, stone, etc�, the
diamond cutting discs 18 can overheat and fail� It is
indicated by the appearance of ring sparks rotating
along with diamond cutting discs 18�
• In this case, remove the power tool from the cut and
let it idle at low speed to allow the diamond cutting
discs 18 to cool�
• A noticeable decrease in performance and rotat-
ing ring sparks indicate that the diamond cutting
discs 18 have become dull� You can try sharpen-
ing them by making a few short cuts in an abrasive
material (for example, in silicate brick)� If this does
not work, the diamond cutting discs 18 must be
replaced�
Power tool maintenance / preventive
measures
Before carrying out any works on the power tool it
must be disconnected from the mains.
Cleaning of the power tool
An indispensable condition for a safe long-term exploi-
tation of the power tool is to keep it clean� Regularly
flush the power tool with compressed air thought the
ventilation slots 1�
