1.5 Water inlet

l Connect the hose coupling with the threaded
water inlet on the unit.
Connect a water supply hose (not supplied with
l
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
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, firmly
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.
