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 spray lance for this
Check that the user information 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 appliance door and empty the coin box.
Is the hot air fan operating?
Is the setting of the thermostat regulator correct (warmer than -10 °C - level "I", colder
than -10 °C - level "II")?
Is the frost protection device operating (frost protection water quantity of approx. 0.5 l/min)?
Is the tool holder drain opening 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 the presence of detergent, clean detergent fil-
ter if necessary.
Checking the functionality of all washing programs
Is the salt level above the water level? Top up the 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). Target value: Less than 3 °dH.
Mix a 10% solution of the "Washing hall and tile cleaner RM 841" detergent, 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 a 20 % solution of "Washing Hall and Tile Cleaner RM 841" detergent, apply to the
surface and allow to react for approx. 2 to 3 minutes. After the contact time, clean the
surfaces with a damp pad or microfibre cloth and then rinse thoroughly with a high-
pressure jet. If desired, the large surfaces can be wiped off with a rubber squeegee.
Mix a 10% solution of the "Washing hall and tile cleaner RM 841" detergent, 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 solvents.
Shut off the fresh water inlet, unscrew the filter cup, replace the filter insert, refit the
new filter insert and filter cup, open the fresh water inlet.
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 is de-
cisive).
Water quantity smaller with frost protection circuit: Clean the frost protection
pump filter, clean the sieve (on the frost protection ball tap), flush the line.
Larger water quantity for all tools: Regulate the water quantity with the frost protec-
tion ball tap.
Larger water quantity only at the high-pressure gun: Replace the node piece in
the high-pressure gun.
WARNING
The high-pressure gun can move uncontrollably and cause injuries if the frost
protection water quantity is too high.
Be sure to replace the node piece in the high-pressure gun if the frost protection 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, refill with softening salt and put back
into operation. Danger of malfunctions. When topping up with softening salt, use only
the softening salt in tablet form listed in the chapter 'Accessories'.
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.
See "Cleaning the frost protection/Power foam nozzle". Determine the following clean-
ing intervals according to experience.
Shut off the fresh water inlet, unscrew the filter cup, replace the filter insert, refit the
new filter insert and filter cup, open the fresh water inlet.
Safety check according to the directives for liquid jet cleaners/accident prevention
