to adapt the diameter of the disc hole to the diameter of the spindle bushing. When using segmented discs, the gap between the
segments must not exceed 10 mm, and the angle of attack of the segments must be negative (VIII).
Screw the additional handle (IX) to the disc guard.
Setting the cutting depth (X)
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 extending or retracting the movable disc guard. An approximate cutting depth scale has been
applied to the guard, but it is recommended that you take a separate measurement to be sure of the set cutting depth.
Loosen the movable guard lock knob but do not unscrew it completely, set the required cutting depth from the range presented in
the table, then tighten the knob fi rmly and securely by locking the movable guard in the set position.
Connecting to the dust extraction system
Warning! Before starting any works related to connecting to the dust extraction system, make sure that the wall chaser is turned
off , and the power cord plug is disconnected from the electric outlet.
Due to the fact that the wall chaser is only suitable for dry operation, large amounts of dust are generated when cutting ceramic
materials. For this reason, upper respiratory protective equipment and an external dust extraction system, such as an industrial
vacuum cleaner, should be used. The fi xed tool guard has a connection for connecting an external dust extraction system. The
dust extraction system hose can be connected directly to the opening in the guard or using the connector. Neither the hose nor the
connector is included in the tool. The hose should be fl exible so that it does not interfere when carrying the tool.
Caution! It is not recommended to use a standard household vacuum cleaner as a dust extraction system. Fine dust from cutting
ceramic materials can damage a vacuum cleaner that is not designed to collect this type of dirt.
Turning the tool on and off
After completing all the steps described above, make sure that the power tool switch is in the "off " position, i.e., it is in the rear
position, and the "O" symbol is visible. Then plug the power cord plug into the electric outlet.
Grasp the tool by one hand behind the housing so that the switch is within reach of your fi ngers and place the other hand on the
additional handle (XI). Make sure that the discs do not come into contact with any object, then press and hold the rear part of the
switch and move it forward. This will start the tool motor.
Allow the tool to achieve its nominal rotational speed and hold it in this position for approx. 30 seconds. If abnormal vibrations,
unusual noise, or other symptoms of non-typical work are observed during this time, immediately turn off the power tool by releas-
ing the pressure on the switch.
The switch can be locked in the "on" position during operation, and it is not necessary to hold it down all the time. If, during the
operation, there is a power failure, the tool will not resume operation automatically when power is restored. To resume work, turn
the switch to the "off " position and turn on the tool again.
The tool is turned off when the switch at the rear part is pressed; the spring will automatically move it to the "off " position. It is
recommended to check the operation of the switch before connecting the tool to the power supply.
Wall chaser operation
Before starting work, it is recommended to mark the cutting line with, for example, a pencil.
Caution! The wall chaser is intended only for cutting in a straight line on a fl at surface. It is forbidden to cut arches or work on a
non-fl at surface.
After turning on the tool and observing no symptoms of abnormal operation, you can start work with the wall chaser.
If you start cutting from an edge, e.g., a wall corner, place the front part of the base of the movable guard against the wall and then
guide the wall chaser along the cutting line.
If a plunge cut is required, place the rotating discs against the fl oor at the start of the cut and rest the back of the movable base
against the fl oor. The back of the movable guard is equipped with a roller that makes it easier to plunge the discs when starting
the plunge cut and guiding the power tool through the fl oor. Plunge the disc completely according to the pre-set cutting depth so
that the base of the movable guard fully adheres to the fl oor. Then start cutting by guiding the wall chaser along the cutting line.
After fi nishing cut, place the wall chaser so that the discs do not come into contact with any object, then turn off the power tool,
and wait for the discs to stop completely.
Disconnect the power cord plug of the power tool from the electric outlet and start maintenance works related to the wall chaser.
If the cut is made in hard material, e.g., concrete, and at the same time deep enough, a special chase breaking tool (available
separately) can be used to form a chase. Insert the tool with the narrow end into the cut gap and then, by blocking the tool against
the edge of the cut gap, break out the part between the cut gaps using the lever principle (XII). If the cut is too shallow or made
in a material that is too soft, e.g., gypsum or brick, the use of the tool may be unsatisfactory. In this case, use a chisel or cutter to
remove the material from between the cut gaps.
