Maintenance Information; Tanks; Suction Hose; Squeegee - Kruger KF455E Manual

After having completely dried any traces of water
on the surface, wait a few seconds and then lift the
squeegee and turn off the suction motor.
Move to a suitable location to drain the tanks;
empty and clean the tanks (as described in 6.11).
Turn off the machine using the key and remove it
from the control panel.
If necessary, charge the battery (see the relative
section).

7. MAINTENANCE INFORMATION

• Turn the key, remove it from the control panel
and disconnect the battery from the machine wi-
ring.
☞ All work on the electrical system as well as all
maintenance and repair operations (especially
those not explicitly described in this manual)
should be carried out only by authorized service
centers or by specialized technical personnel who
are experts in the sector and in the pertinent safety
regulations.
Performing regular maintenance on the machine,
and carefully following the manufacturer's instruc-
tions, is the best guarantee for obtaining the best
performances and extended machine service life.
7.1

TANKS

Drain the two tanks as described in the relative
sections.
Remove any solid dirt by filling and draining the
tanks until all dirt has been eliminated: use a wa-
shing hose or similar tool to do this.
• Water hotter than 50°, a high-pressure
cleaner or excessively powerful sprays may
damage the tanks and the machine.
Leave the plugs of the tanks open (only while the
machine is not being used) so that they can dry
and thus prevent the formation of foul odors.
7.2

SUCTION HOSE

Detach the suction hose from the squeegee ( Photo
H - 3).
Now you can wash the hose and remove any ob-
structions.
Firmly insert the hose on the squeegee body.
7.3

SQUEEGEE

• Do not handle the squeegee with bare hands:
wear gloves and any safety clothing needed to
carry out the operation.
Detach the squeegee from the machine and clean
it under running water using a sponge or a brush.
Check the efficiency and the wear on the strips in
contact with the floor. They are designed to scrape
the film of detergent and water on the floor and to
isolate that portion of the surface to enhance the
vacuum of the suction motor: this ensures that the
machine will dry very efficiently. Working constan-
tly in this manner tends to round or to deteriorate
the sharp edge of the strip, thus reducing drying
efficiently. This is why the squeegee strips must
be replaced.
To replace the worn blades, follow the instructions
in the relative section. Turn the blades around to
wear down the other sharp corners or to install
new ones.
7.4 ACCESSORIES
Remove and clean the brushes or the scraper disks.
• To avoid damaging the floor and the machine,
carefully check if foreign matter, such as metallic
parts, screws, chips, cords or similar items, has
become jammed.
Check that the brushes are flat as they work on
the surface (check for any irregular wear on the
brushes or on the abrasive disks). If necessary,
adjust the slant of the action on the floor.
Use only the accessories recommended by the ma-
nufacturer: other products may reduce operating
safety.
7.5 MACHINE BODY
Use a sponge or a soft cloth to clean the exterior of
the machine and, if necessary, a soft brush to elimi-
nate tough dirt. The machine's shockproof surface
is rough to make it harder to see scratches caused
during use. However, this does not make it easier
to remove tough stains on the surface. It is prohi-
bited to use steam machines, hoses with running
water and high-pressure cleaners.
7.6 BATTERIES
PB-Acid batteries
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all
the other instructions provided in this manual.
Exposing the element plates (not completely im-
mersed in the acid solution) will lead to rapid oxida-
tion and irreparably reduce the element's operating
capacities.
An overflowing acid solution may corrode the ma-
chine.
Use battery chargers recommended by the manu-
facturer and, in any case, those that are suitable
for the type of battery to be charged.
Always charge batteries in well-ventilated rooms:
there is an explosion risk!
The use of gel or maintenance-free batteries is hi-
ghly recommended.
GEL batteries
Carry out maintenance operations in accordance
with the manufacturer's instructions and with all
the other instructions provided in this manual.
Use only those battery chargers recommended by
the manufacturer.
