1. Unit Start-Up
1.5 Water inlet
l
See „Specifications“ for connection data.
l
Connect the hose coupling with the threaded
water inlet on the unit.
l
Connect a water supply hose (not supplied with
the unit) with the unit, and with the water mains.
1.6 Suction feed operation
To draw water from an open reservoir, proceed as
follows:
– Remove the threaded coupling from the unit’s
water inlet, and directly connect a suction feed
hose with filter (order no. 4.440-238) to the water
inlet.
– Set the metering ring on the detergent suction
hose to zero.
– Without the high-pressure hose being attached,
operate the pump until a solid stream of water
exits at the high-pressure outlet.
– At this point, connect the high-pressure hose
again.
Note:
Dirt in the feed water could lead to the appliance
being damaged. To avoid this risk, we recommend
fitting a filter. A suitable filter with 3/4" connection.
1.7 Spray lance
Vario Power
l
To attach the spray lance to the hand gun, insert
the spray lance into the bayonet coupling of the
hand gun. Overcoming the spring pressure, firm-
ly press the lance into the coupling and twist it a
quarter-turn until it locks into place.
If required, you can use the additional spray lance
extension.
