Measuring out the cleaning agent, Intended use

English HDS Super, HDS 695 S, HDS 745, HDS 895 S, HDS 995, HDS 1195, HDS 1295

Measuring out the cleaning agent

*Use cleaning agents sparingly to protect the environment

*The cleaning agent must be suitable for the surface to be cleaned.

Set the concentration of the cleaning agent according to the manufacturer's recommendations at the cleaning agent metering valve (item 31)

Approximate values at maximum operating pressure

Intended use

Cleaning of: Machines, vehicles, buildings, tools, facades, terraces, garden tools, etc..

*Engine cleaning is only to be performed in areas provided with oil separator.

*Heed appropriate safety regulations for use at petrol stations or in other hazardous environments.

Working with high-pressure nozzle Spray angle is crucial to efficiency of high- pressure jet.

Use is normally made of 25°fan jet nozzle (included).

Recommended nozzles, available as accessories

–For stubborn dirt 0°full jet nozzle

–For delicate surfaces and slight contamination 40°fan jet nozzle

–For thick layers of stubborn dirt dirt blaster

–Nozzle with variable spray angle, for adaptation to various cleaning tasks variable- angle nozzle

Cleaning

*Set pressure/temperature and cleaning-agent concentration in line with surface to be cleaned

*Always start by directing high-pressure jet from a good distance at object to be cleaned to avoid damage caused by excessive pressure.

Recommended cleaning method

Loosen up dirt:

Spray on cleaning agent sparingly and allow to react for 1...5 min (do not allow to dry on).

Remove dirt:

Spray off loosened-up dirt with high-pressure jet.

Operation with cold water

Removal of slight contamination and rinsing e.g.: Garden implements, terrace, tools, etc.

Set operating pressure as required

Set the temperature regulator (item 24) to "0"

Operation with hot water

*Danger of scalding

Set the temperature regulator (item 24) to the required temperature

We recommend the following cleaning temperatures

–Slight contamination 30-50°C

–Protein soiling, e.g. in foodstuffs industry max. 60°C

–Motor vehicle cleaning, machine cleaning 60-90°C

Operation with steam

At operating temperatures above 98°C operating pressure must not exceed 32 bar.

Therefore the standard high-pressure nozzle must be replaced by the steam nozzle (manufacture no.: 4.766-023, for HDS 1195 and HDS 1295 4.766-024.0; see accessories).

–Set operating pressure to minimum value. See figure 9

–Set the temperature regulator (item 24) to min. 100°C

*Danger of scalding!

We recommend the following cleaning temperatures

–Preservative removal, extremely greasy dirt 100-110°C

–Thawing of aggregates, certain facade cleaning operations up to 140°C
