4.5. Break time

The spraying can be stopped arbitrarily by releasing the handle off the spray gun. Next acts one must comply, if
the spraying pause last longer than ten minutes (or by abandoning the working area):
- After cleaning at use of the burner, the temperature must be 0°C and you have to spray during at least an-
other 5 minutes for cooling down the burner sufficiently.
- When you decide to switch between steam/WeedKiLLER function and high pressure function: rince with
cold water during 10 minutes (cooling down).
- Switch off the machine completely. Put therefore the key contact to position "0".
- Release the pressure of the pressure hose by pushing the handle of the spray gun for a moment.

4.6. Pumps HT

There must be present a pre - pressure (pump) at HT pumps (pumps with high temperature).
The pre - pressure (pump) must provide for sufficient flow of water to feed the high pressure pump and to occur
cavitation. Cavitation is the phenomenon that in a moving fluid the local pressure is going to be lower than the
vapour pressure of the fluid. Because of this mist bells will arise who can implode with high power in the pump
and could cause damages. For all these applications at high temperature, it is ABSOLUTELY ESSENTIAL to feed
the pump with positive pressure (at least 3 bar) and with a sufficient quantity of water.

4.7. Scope of application

Efficient high pressure cleaning is achieved by following a few guidelines combined with your own experiences.
Each cleaning job is different and specific, therefore contact DiBO for the best solution in your application sector.
Using cleaning products (if applicable): the surface to clean should be sprayed so the product can act during
some time (do not let it dry!) before cleaning with high pressure jet.
Cleaning agents can increase the cleaning effect if they are used correctly!
Always follow/consider the safety instructions of the used product!
Cold water (high pressure) cleaning: removal of (mild) impurities/pollution and rinsing.
Hot water (high pressure) cleaning (if applicable): the cleaning effect will be such improved through increasing the
temperature (set the temperature experimentally according to the application).
Cleaning via lance with rotating head (if applicable): cleaning method to remove tough layers of dirt.
Cleaning using a steam lance (if applicable): this steam function (by overheating water) is used in 'sensitive' clean-
ing applications (eg: damage sensitive surfaces) where there is stubborn dirt (eg: degreaser) is removed by using
steam. Please note: this application has high cleaning temperatures and requires various safety measures!
Intended Use: this pressure washer has been developed for use in various professional applications (eg: building
technology, cleaning technology, industrial, transport sector, ...).
