Operating instructions
4. Spray handle - accessories
Rinse the nipple before attaching the
spray lance.
Pull the gray part of the spray handle (1) forward.
Insert the nipple (2) of the spray lance or accessory in the quick coupling and release #1.
Tug on the spray lance or accessory to ensure it’s tight before starting the machine.
5. Detergent metering unit
Only use suitable detergents.
Use of aggressive detergents may
damage the equipment and affect the
environment.
Flush with water after use.
IMPORTANT: Always set the injector to
„0“ when not using detergents.
Detergents are added under low pressure through the built-in metering unit (1). The pickup hose and
screen (3) of the metering unit is stored near the container support (2). Some container s can be hung on
the support by the handle. Insert the pickup hose with filter into the bottle or the container. Metering is
infinitely adjustable from 0-5%. Select the required concentration by turning the knob (3) counter-clockwise,
until the desired setting is aligned with the arrow. When finished with the detergent system, flush it with
water (in place of detergent), at setting ‘5’ for approximately 1 minute. Return the knob to position 0.
3.2 Starting procedure
Turn on the water.
Vent the machine.
Turn the start/stop knob (1) to position I.
Turn on the water supply and squeeze the trigger on the spray handle with the spray lance set at low pres-
sure (or without a spray lance attached). Let the water run until all air has escaped from the supply hose,
pump, and high pressure hose (a hissing sound will be heard until the air is gone).
During start-up, pump pressure may be irregular if air is left in the system. After a short time in operation
the air will escape from the system, and the pressure will normalize.
