4. Checking the detergent feed
Start the cleaner and switch over to “operation
with detergent” by turning the 3-way nozzle to
low-pressure CHEM. Turn the detergent-feed
knob to “O”.
When the metering valve is set to position “O”,
no detergent must be drawn into the cleaner. If
detergent is drawn in, then the knob must be
pulled off and the detergent metering valve
should then be turned hand-tight to close the
valve completely and then the knob should be
pressed back on (the stop limiting the rotation of
the knob is at the side of the housing).
5. Checking the detergent flow
The maximum detergent flow is checked by
turning the knob to the maximum setting and by
measuring the quantity of detergent drawn from
a measurement glass in a given time (see
technical data).
