Safety Instructions; Preparatory Work - Wetrok Sprinter XR 70 Instrucciones De Manejo

follow the instructions contained in them.
Safety instructions for operating and
maintaining the machine are presented in
the relevant sections of this manual and
must be followed unconditionally.
Also observe the safety tips contained in the
pictograms on the machine.
3. Operation / Use tips
Depending on the model and equipment, the
design of your unit may differ in matters of
detail form the standard design as described.
The brush housing for the XR70 can be ex-
changed easily with the XR90 brush hou-
sing. The Wetrok service department will be
happy to advise you.

3.1 Safety instructions

– Inspect the machine before each use. Al-
low only qualified professionals to repair
damage.
– The tank housing (E1) and tank cover
must be closed and locked before use.
– Use caution when working near other
persons, especially children.
– To avoid injury, wear solid footwear.
– Before cleaning and maintaining the ma-
chine, replacing or dismantling working
parts, drive the machine onto a flat, level
surface and remove the key from the
main switch.
– Only original Wetrok working parts may
be used.
– The machine may be used only on slopes
or gradients no greater than 8%. Use ex-
treme caution and travel slowly when ma-
king turns on rising or falling slopes. When
moving over ramps, the direction of travel
must be perpendicular to the gradient.
– The machine must be secured against
unintentional movement when left on a
slope or lift. Remove the key from the
main switch.
– The cable connection between batteries
and the machine must be removed before
any work is performed on electrical compo-
nents. (Emergency stop connector: G1/H1)
3.2 Use restrictions
The machine must not be used in tempera-
tures below 1° C or above 45° C. The water
temperature must not exceed 50° C.
Foaming or corrosive cleaning agents or
combustible solvents must never be used.
Use only water and machine-compatible cle-
aning agents.

3.3 Preparatory work

Begin by removing large particles and paper
from the surface to be cleaned.
Note: The machine can pick up coarse parti-
cles such as gravel or wood splinters. Make
sure, however, that sensitive surfaces are
swept or damp wiped in advance, as scratch
marks may otherwise occur.
3.4 Setting up
The choice of cleaning agents and working parts
depends on the type of floor and the degree of
soiling. Always observe the correct dosage.
Thorough cleaning or heavy soiling
Wetrok Remat or Antiwax/Exal.
Dilution 1:20.
Smooth floors: pad drive disc with Wetrok
polypad (black or green)
Rough floors (e.g., natural stone): scrubbing
brush
Regular cleaning:
Wetrok Redur or Resal. Dilution 1:100.
Pad drive disc and green or red polypad, in
some circumstances a scrubbing brush
Dismantling / installing working parts:
– Only original Wetrok working parts may
be used.
– To release the brushes, press button
(P16) on the operating panel. An anima-
ted graphic will appear on the display.
– Remove old working parts.
– Pre-position new working parts by hand
on the floor under the brush housing
(A2). If using pads, attach them before-
hand to the pad drive discs.
– Couple brushes or pad drive discs with
pads. Press button (P17) on the operating
panel. An animated graphic will appear
on the display.
Use caution with sensitive floor coverings.
Filling with fresh water / cleaning
agents:
– Lift up the tank cover.
– Fill the fresh water tank (F5) with water.
– Add the desired cleaning agent in the
prescribed dosage. Always observe the
correct dilution! The tank's diaphragm is
provided with markings as a guide.
– Close the tank cover.
Setting up the suction nozzle
The ideal result depends on the suction lips
used, the application pressure and the setting.
Set the tilt angle (B1) and the height adjust-
ment (B3) to achieve the optimal suction effect.
3.5 Operation / Initial operation of the
machine
Check:
– The emergency stop connector (G1)
must be plugged in and functioning (with
the battery charger cable removed).
– Check the driver's seat position. After ad-
justing the seat, make sure that the sea-
t's locking device is engaged
Driving
– Enter the direction of travel (P6/P7):
LED for forwards illuminated = forward travel
LED for backwards illuminated = reverse travel
– Select maximum or reduced speed. Press
button P14 or P15 on the operating panel.
– Actuate the accelerator pedal (A5).
CAUTION: Adjust the speed to the nature or
condition of the floor, the environment and
the level of soiling (see Traction control).
All functions are started by pressing the
Go/Stop button (brushing, water feeding
and suction).
NOTE:
– When the machine is switched on with
the main key switch (G2), it goes automa-
tically into the «zero» position before new
commands can be entered (the brush lift
and nozzle motors are in their highest li-
mit positions, and all motors are turned
off). When «Go» appears on the display,
the machine is ready for use.
– When the machine is switched off, it re-
quires a short period of time to complete-
ly switch off the controls. It is best to wait
a few seconds before switching the ma-
chine back on.
– When left idle, the machine will turn itself
off after a while by means of the «power
down» function in order to protect the bat-
tery.
– Pull the emergency stop connector if the
machine will not be in use for an exten-
ded period.
– If the battery discharge indicator (P1) is
not on «half full» or «full» when the machi-
ne is turned on, the batteries must be
charged before the machine is used (see
the Battery discharge monitor section).
– The brush housing (A2) is lowered by
pressing the «Go» button. Water feeding,
brush rotation and suction will begin auto-
matically (see also the Adjusting the
brushes section).
– When the machine is standing still, the
brush housing (A2) will descend only as
far as the stand-by position (1 second be-
fore contact with the floor). It will descend
further into the working position only
when the machine begins to travel (for-
wards or backwards) (see the Lowering
the brushes section).
– If the machine remains in one spot for ap-
prox. 2 seconds, the brush housing (A2)
automatically rises to the stand-by posi-
tion, and the brushes cease rotating. The
LED for button P8 will blink while the
stand-by position is maintained. Only
when the machine begins to move again
(forwards or backwards) will the brushes
leave the stand-by position to resume
their activity and the brush housing (A2)
redescend into the working position (see
the Lowering the brushes section).
– If the brush motor experiences an overlo-
ad, the application pressure is automati-
cally corrected by raising the brush lift
motor. If the correction is unsuccessful,
the brush motor will stop at the same time
that it rises to the park position. F20 will
appear on the display.
– For indirect work, suction can be turned
off with the P10 button (full suction) or
P11 button (reduced suction). The appro-
priate LED will blink.
– Brush pressure (P2/P3) and water quan-
tity (P4/P5) can be readjusted with the
push buttons according to the level of so-
iling. When the machine is turned off
completely with the main key switch (G2),
water quantity and brush pressure return
to their default settings.
