Danger

Danger of scalding by means of hot water. 
Hot water comes out from the movable foot 
of the unit. Do not keep your feet below the 
unit while opening the drain tap.



Open the drain tap of the boiler and 
empty the boiler.



Close the drain tap of the boiler.

When putting into operation for the first 
time after manual antifrost, close the man-
ual valves for fresh water and processed 
water (option).

If the minimum temperature is undercut:

–

any wash operation which is in progress 
is completed.

–

the gantry hoses and jet pipes are 
blown out with compressed air

–

No more wash programme can be started.

Should the anti-frost measures be intro-
duced with automatic anti-frost as a pre-
caution when the plant is shut down, an 
additional switch can be installed by the 
factory.
Once the danger of frost has passed, the 
plant automatically resumes a state of op-
erational readiness.

Note

If the attachment set "Anti-frost boiler" has 
been installed, then the boiler must be re-
filled when the frost risk is over:



Switch on the functions "Fresh water" 
and "hot wax" in the manual operations 
"Group 5 Water" until the boiler has 
been filled up.

The basis for a safe operational plant is the 
regular maintenance according to the fol-
lowing maintenance plan
Use exclusively original parts of the manu-
facturer or those parts recommended by 
him like

–

replacement and wear parts

–

accessory parts

–

fuel,

–

detergents.

Danger

Risk of electric shock. Switch on the plant 
voltage-free, in addition switch on the main 
switch to “0” and secure against it switching 
on again.
Risk of injury from compressed air unexpect-

edly emerging. Compressed-air cylinders 

and lines also remain under pressure after 

the plant has been switched off. It is absolute-

ly necessary to get rid of pressure before 

starting work on the plant. To do this, turn off 

the compressed air supply and move the 

wheel wash system in and out in manual 

mode to release the pressure.    Then check 

for the absence of pressure on the manome-

ter at the maintenance unit.

Risk of injury from high-pressure water jet un-

expectedly emerging. It is absolutely neces-

sary to remove all pressure in the high-

pressure system before starting work on the 

plant.

Risk of eye injuries from parts flying off or dirt. 
Keep clear of rotating brushes. Goggles must 
be worn during maintenance work.

Your own safety and the safety of others 
demands that the plant is switched off dur-
ing maintenance and service work. Howev-
er, not all plant parts on which maintenance 
is being done are freely accessible. This 
makes it necessary to move certain plant 
parts during maintenance and servicing 
work. The operational mode “Manual Oper-
ation” is intended for this. Manual operation 
is carried out using the operating point for 
manual mode.
