Putting The Machine Into Operation; Working Method; Daily Maintenance - Wetrok Servomatic 43 KA Mode D'emploi

3.5.1.3. Maintenance cleaning
Use Wetrok Brill or Wetrok Plus (dosage
according to label on container) and pad drive
disc with Wetrok Polypad green or red.
For cleaning napped or exposed aggregate
concrete floors: use Nylon (H2) or exposed
aggregate concrete brush (H3) and special
nozzle 42 (H 9) for vacuuming off.
3.6. Putting the machine into
operation
– Put flip switch for water feed (A 2) in Position
«On». (Position «On» = permanent water
feed, Position «Pulse» = dosed water feed.
Water feed only takes place when the brush
motor is switched on).
– Switch on suction motor (A10).
– Lower suction nozzle (A18) with lever (A8).
– Operate switch (A3) on handle (brush motor).

3.7. Working method

It is expedient to clean poorly accessible corners
and recesses by hand. It is advisable to first clean
the edge areas by driving with the machine along
them in the anticlockwise direction. The
remaining areas are cleaned in strips in the
direction away from the socket. On turning the
curves, it is advisable to turn off the water feed or
to dose as needed with the pulse switch (A 2).
Work in overlapping strips.
Note:
Be sure to work away from the socket and
always turn the machine away from the
cable.
Observe the floor in front of and behind the
machine during working. Adapt the speed and
water feed to the degree of soiling in good time.
Insufficient water feed reduced the cleaning
effect. The dissolved dirt should float in as much
water as possible in order that it can be
vacuumed off completely.
By raising the shaft of the machine, one can also
clean and vacuum in corners, recesses, narrow
passages and corridors without problems. For
this purpose, the shaft of the machine should be
placed as upright as possible. Switch on the
traction motor. By turning the handle, one can
guide the machine effortlessly into any corner
(Fig. D) or turn on the spot in narrow openings.
Residual water can be vacuumed off afterwards
by either of two methods: pulling the machine
backward over the wet area or by switching on
the traction motor, depressing the shaft until the
working element is clear of the floor, and then
pushing the machine in this position with lowered
nozzle over the wet area.
The Wetrok Servomatic 43 can if necessary also
be used as a normal vacuuming appliance for
water. In this application, the connecting hose
from the nozzle to the soiled water tank must be
pulled out of the opening in the cover. Insert the
suction hose (2.5m) and work in a conventional
manner with tube and water suction nozzle. (For
accessories, see Figs. H7, 9, 10).
3.7.1. Emptying the soiled
water tank
(Fig. E)
The soiled water tank is provided with an
automatic shut-off device, which reacts to foam
and water. As soon as the useful volume is
reached, the float (G1) interrupts the suction
flow, which is indicated by a change in the sound
of the suction.
Switch off suction motor by operating the flip
switch (A 10). Lift the lid of the soiled water tank
and hook it on the tongue of the fresh-water tank.
Lift the soiled water tank, empty and thoroughly
rinse out with a large amount of clear water. The
clean soiled water tank can be used as a bucket
to replenish with fresh water. If fine grained dirt
particles find their way with the fresh water into
the fresh-water tank, this can lead to blocking of
the filter sieve or even to faults in the solenoid
valve. (See also under the headings Mainte-
nance and Troubleshooting.)

3.7.2. Emptying the fresh-water
tank
(Fig. F)
The unused cleaning liquid can be sucked up in
the following manner. Pull the connecting hose
from the nozzle to the soiled water tank out of the
opening in the cover. Insert the supplementary
suction hose and suck the fresh-water tank
empty.
4. Maintenance
Important! Before starting maintenance work,
pull the mains plug from the wall socket!

4.1. Daily maintenance

Keeping the machine clean is the prerequisite for
flawless functioning and a long service life.
The following rules should therefore be given
special attention:
– Completely empty the fresh-water tank by
means of the supplementary hose (Fig. F).
(Figs. A, D, H)
Rinse out with clear water.
– Clean sieve inside tank.
– Completely empty soiled water and rinse out
thoroughly.
– Thoroughly rinse off the float (G1).
– Clean cable with a moist cloth.
– Wipe down the entire machine with a clean
cloth.
– Detach suction nozzle, thoroughly clean
suction slot and lips.
Before putting away the machine, remove
working elements. Never leave the machine
standing on pad drive disc or brush.
4.2. Maintenance of the motor
– The motors of the Wetrok Servomatic series
are maintenance-free.
– For periodic overhauls, we recommend
taking out a maintenance contract.
5. Troubleshooting
5.1. Possible causes of weak
suction
– Soiled water tank full (full tank interrupts
suction flow)
– Cover does not lie tightly on soiled water tank
(air leak)
– Feed hoses are wrongly inserted into cover
(loss of vacuum)
– Suction nozzle or suction hose blocked
– Suction lips worn out (replace as necessary)
– Suction nozzle wrongly adjusted (angle to
floor)
– Closure valve in cover soiled water tank is
blocked with waste and dirt
– Solid dirt particles are sticking to suction lips
5.2. Possible causes of insufficient
cleaning performance
– Worn cleaning elements
– Working too fast
– Too little cleaning liquid on the floor, faulty
water feed hose, valve sieve in fresh-water
tank contaminated
– Wrong working element
– Wrong brush adjustment. Too strong a
forward pull of the machine, i.e. working
element inclined too steeply.
6. Servicing
Wetrok machines are tested for safety in the
works.
maintenance of value, servicing must be
performed regularly at intervals depending on
their use. The service shall only be carried out by
the Wetrok Service Department or an authorized
specialist. Wetrok offers a service contract.
7. Storage, transport
If the machine is no longer being used, it should
be stored in a dry state and under normal room
conditions. The water tank must be emptied.
During transport over long distances, the
machine must be suitably secured and packed.

8. Technical
improvements
We reserve the right to make technical
improvements. For this reason, the machine may
differ in details from the data in the Operating
Instructions.
9. Disposal
Machine, packaging, unused and vacuumed up
cleaning agents must be disposed of in
accordance with the national regulations.
