Water Connection

·

See technical data for connected values.

·

Screw the quick coupler female to your garden
hose (not supplied) and the quick coupler male
onto the water connection of the appliance.

·

Connect a water supply hose (not supplied) to the
appliance and the water pipe.

Suction

Observe the following if you are drawing water from
an open container:

Unscrew the union element from the water
connection of the appliance, and attach a suction
hose with filter (order no. 4.440-238) directly to
the appliance.

Allow the pump to operate without the high-
pressure hose until water appears at the high-
pressure outlet without any more bubbles.

Then re-attach the high-pressure hose.

Note:

Dirt in the feed water could lead to the appliance
being damaged. To avoid this risk, we recom-
mend fitting a filter with 3/4" connection .

Hand-held Spray Gun

with safety ratchet and high-pressure hose

·

Connect the high-pressure hose to the high-
pressure outlet.

Note:

The safety ratchet does not lock the lever of the
gun during operation but only prevents it from
opening unintentionally.

Spray Wand

with Pressure Regulator

·

Push the spray wand against the spring into the
bayonet connector of the gun, and then rotate it
through 90 ° until it clicks into place.

Please contact your dealer immediately if, on
unpacking the appliance, you discover damage
has been caused during transportation.

Electrical Connection

·

See technical data of connected values.

·

Check whether the voltage shown on the rating
plate corresponds to that of the power source.

Note:

If you are using an extension cable, it should
always be completely unwound from the cable
drum and have a sufficient cross-sectional area:
Up to 25 ft = 12/3 AWG; 25 to 50 ft = 10/3 AWG
