on the machine's technical data plate.
22) The mains outlet must be earthed and protected against current leakage
(differential). When using an extension cord, make sure the cable cross
section measures no less than 2.5 mm².
23) The blade guard protects the user from injury during cutting. When cutting, the
guard should therefore be adjusted according to the thickness of the piece to
be cut.
24) 230 V machines may also be connected to 210V / 240V. 110 V machines may
be connected to 100V / 120V.
25) During transport, gather the power cord by winding it up. Never move the
machine by pulling on the power cord.
26) If the blade is installed incorrectly and is working in the wrong direction, stop
the machine and correct the blade installation.
27) Use only the blade diameters indicated in this manual.

3.2 STARTING THE MACHINE

PROPER POSITION OF THE HANDS:
SQUARE CUT
28) To make square cuts, position yourself behind the machine. Put one hand on
the main handle and slide the cutter in the guide. For greater comfort, place
the other hand on the machine chassis. This provides better balance and
sliding of the cutter.
MITRED CUT
29) To make mitre cuts, position yourself behind the machine. Put your left hand
on the main handle and slide the cutter along the guide. For greater comfort,
place the other hand on the machine chassis or hold the tile. This results in
better sliding of the cutter and greater precision.
PRELIMINARY CONSIDERATIONS:
30) Read these instructions carefully before using this product and do not throw
them away.
31) The DCX Xpert machines have a fixed support table for positioning the tiles.
This system allows the user to work with great precision and comfort on all
types of ceramic pieces.
32) Sliding is by means of greased and sealed ball bearings.
33) Changing the position from straight cutting to mitre cutting or vice versa,
as well as adjusting the stops for repetitive cutting, must be done with the
motor switched off to prevent possible accidents.
34) When the machine is used outdoors, only extension cables intended for
outdoor use should be used. It should be noted that the extension cable has
to be fully unwound to get maximum power.
35) Before using the machine again, it should be carefully checked to determine
that it will function properly and be suitable for the function for which it
is intended. Any guard or other part that is damaged should be properly
repaired or replaced by the authorised technical service unless otherwise
specified in this instruction manual.
36) Adequate artificial lighting is required in work areas when ambient light is
insufficient.
CONNECTION:
37) Remove the adjustment spanners and tools before starting the machine.
38) Make sure the switch is in the "OFF" position when you plug in the machine.
39) Start the machine by pressing the green button or the I button (fig. 17).
40) Once the machine is running, wait until the motor and the water supply
through the pump are normalised (4 or 5 seconds). Tap A can be used to
regulate the cooling water flow for the blade. (fig. 18).
WARNING! To reduce the risk of serious personal injury, support the work
piece correctly, as shown, and hold the cutter firmly to avoid losing control
and prevent potential kickback.
OPERATING INSTRUCTIONS:
41) Keep your hands and the power cord away from the cutting zone to prevent
it from being snagged or tangled on the piece being cut.
42) To make straight cuts, the blade should advance in a continuous manner,
without jerking and without forcing the motor. Improper operation can break
the part and seriously damage the blade.
43) DCX Xpert machines allow exact parallel cuts to be made with maximum
precision by means of the tile clamping accessory for repetitive cuts (fig.
19, 20).
44) For cutting at 45º (mitre) there is a mechanical locking system which allows
the cutting head to be positioned precisely.
45) The square assembly is attached to the chassis and swivels between 60º
and 0º. It allows users to support the pieces to be cut and to make repeated
cuts (fig. 21). Side stop A is attached to the square assembly. It is factory set
and allows repetitive cuts of 90º and 45º to be made accurately (fig. 22).
46) The electric machines have a safety system to prevent the motor from
overheating.
- 10 -
47) If the motor stops for no apparent reason, you should wait a few minutes as
you will most likely have overloaded it and you should then moderate the
cutting speed.
48) For proper operation of the DCX Xpert machines, work on level ground.
49) Do not use cracked or chipped diamond blades.
50) Do not use side pressure to slow the blades down.
DISCONNECTION:
51) To switch off the machine, press the red button or the 0 button (fig. 17).
52) The cutter will continue to rotate for a few moments after it has been turned
off; wait until the machine is completely stopped before removing it from the
cutting position.
53) Remember that the cutter must be unplugged from the power installation
when moving from one work zone to another and when carrying out
adjustment and maintenance operations.

3.3 CLEANING AND MAINTENANCE

WARNING! Unplug the machine before carrying out any adjustments,
repairs or maintenance.
Proper cleaning and maintenance of the machine can extend its lifetime.
Immediately clean the machine after using, as well as during prolonged
periods of inactivity.
54) Before performing cleaning, maintenance or repairs on the machine, as well
as before transportation, the machine must be switched off and unplugged.
55) Do not use aggressive cleaning products to clean the machine.
56) Do not submerge the machine in water.
57) Examine the machine's cords periodically and if they are damaged, have
them repaired by an authorised technical service.
58) Keep handles dry and clean and free of grease and oil.
59) In order to keep the machine in good condition, it is advisable to clean it
with water and dry it after use, as well as to circulate clean water through
the cooling system. It is especially important to clean the water pump. The
rusting of metal parts is a direct consequence of the use of water. Proper
maintenance of the cutter will minimise the appearance of rust spots.
60) We recommend cleaning the rolling tracks of the guide with a cotton cloth
dampened with water. No lubrication is necessary.
61) The machine must be put out of service and scrapped in accordance with
the instructions in each country, at a selective collection point for the proper
classification and processing of materials.
WARNING! Continued or improper use, constant changes in location
and transportation of the cutter can cause the components to become
misaligned.
For proper functioning of the cutter, it is advisable to check the following
adjustment points:
MOTOR ADJUSTMENT:
Check the play of the blade head regularly and adjust it if necessary (fig.
23, 24):
a) Loosen screws A and nut B as indicated.
b) Gently tighten set screw C with the help of a 3 mm Allen key.
c) Check the head play and retighten nut B to lock the system, then
retighten screws A.
SQUARE ADJUSTMENT:
63) Check that the square assembly is perpendicular to the blade. To adjust it
exactly to 90° (fig. 25,26):
a) Place a set square in line with the blade at 90º on the square and adjust
screws A as indicated.
b) The square assembly can pivot with respect to the shaft (screw B).
c) For better positioning of the whole assembly, the DCX Xpert machine has
a transversal screw that allows the whole assembly to pivot (rotate) with
more precision.
d) Loosen screws A and rotate the square assembly using transversal screw
C until it reaches the 90º position in relation to the blade.
e) Tighten the assembly again to lock the position.
BLADE ADJUSTMENT (PERPENDICULARITY AND PARALLELISM):
PERPENDICULARITY
64) To set the disk at 90º, remove the blade guard, loosen knob A and the
locknut, and place the set square on the table touching the blade (fig. 27)
a) Adjust the blade inclination using the screws indicated in the picture (fig.
28). Perform this operation on both sides of the machine, until the top and
bottom of the blade touch the set square at the same time.
b) Replace the blade guard and then tighten the nut and knob.
