Maintenance plan
RO: only carry out for systems with reverse osmosis.
Performed
Examine the high-pressure hoses for mechanical damage such as abrasion damage,
visible hose fabric, kinks and cracked rubber. Replace damage high-pressure hoses.
Check the washing brushes for damage, soiling and wear. Replace bristles that are
shorter than 30 mm. In winter at temperatures below –5 °C, check for ice formation
and lock the foam wash if necessary. Replace the combination spray lance with a high-
pressure jet lance for this
Check that the user notices are present and legible.
Check pump and line system for leaks. Contact Customer Service when oil is present
under the high-pressure pump or when more than 3 drops of water per minute escape
from the high-pressure pump during operation.
Check the filling level and refill if necessary.
Open the device door and empty the coin box.
Is the hot air fan operating?
Is the setting of the thermostat controller (warmer than -10 °C - level "I", colder than -
10 °C - level "II")?
Is the frost protection device in operation (antifreeze water volume of approx. 0.5 l/
min)?
Is the tool loading sequence free?
See the section "Cleaning the sieve".
Clean the filter and re-insert.
The oil level must lie between the MIN and MAX marks, otherwise refill with oil.
Milky oil indicates water in the oil. Notify Customer Service.
Remove dirt from the tool holders.
Visually check the high-pressure jet for detergent, clean detergent filter if necessary. Operator
Check that all washing programmes are functional
Is the salt level above the water level? Replenish softening salt if necessary.
Remove water from the hot water float tank and determine the residual hardness with
test set B (order no. 6.768-003). Set point: below 3 °dH.
Mix 10% "Washing hall and tile cleaner RM 841", apply to the surfaces, allow to react
for approx. 2 to 3 minutes, do not allow to dry. After the contact time, rinse thoroughly
with the high-pressure jet.
Mix 20% "Washing hall and tile cleaner RM 841", apply to the surface and allow to re-
act for approx. 2 to 3 minutes. After the contact time, clean surfaces with a damp pad
or microfibre cloth and then rinse thoroughly with a high-pressure jet. If desired, the
large surfaces can be removed with a rubber puller.
Mix 10% "Washing hall and tile cleaner RM 841", apply to the surfaces, allow to react
for approx. 2 to 3 minutes, do not allow to dry. After the contact time, rinse thoroughly
with the high-pressure jet.
ATTENTION
Risk of damage
Solvents and detergents containing solvents can damage the splash guard tarpaulins.
Do not clean the splash guard tarpaulins with solvents or detergents containing sol-
vents.
Shut off the fresh water supply, unscrew the filter cup, replace the filter inlay, refit the
new filter inlay and filter cup, open the fresh water supply.
Thoroughly clean the exterior and interior of the housing.
Minimum value: approx. 0.5 l/min per washing tool (the tool with the lowest flow rate
is decisive).
Water quantity lower for antifreezing circulation: Clean the frost protection pump
filter, clean the sieve (on the frost protection ball tap), flush the line.
Water quantity higher for all tools: Regulate the water quantity using the frost pro-
tection ball tap.
Water quantity only higher at the high-pressure gun: Replace the connecting
piece in the high-pressure gun.
WARNING
The high-pressure gun can move uncontrollably and cause injuries if the frost
protection water volume is too high.
Do not fail to replace the connecting piece in the high-pressure gun if the frost protec-
tion water quantity is too high.
Remove the filter and rinse thoroughly with clean water.
Check the water level (approx. 5...25 cm above the sieve plate).
Check for deposits, empty if necessary, clean, replenish with softening salt and put
back into operation. Danger of malfunctions. When replenishing softening salt, only
use the softening salt in tablet form listed in the "Accessories" chapter.
Lubricate the hinges with grease (order no.: 6.288-072).
Spray care agent (order no.: 6.288-116) into the locks.
Open the device door. Clean the coin slot (see section "Maintenance work").
If water escapes from the overflow hose, check the seal at the float valve. If necessary,
replace the float valve.
