Before Putting The Machine Into Operation - Scheppach HCE1450 Originalbetriebsanleitung

8. Before Putting the Machine into
Operation
In keeping with current regulations
a pressure washer must never be
operated off the drinking water mains
supply without a controllable back-
flow preventer. A suitable backflow
preventer in conformity with EN
12729 type BA must be used.
Water that has passed through a backflow preventer
is classiied as undrinkable.
A backflow preventer is available from specialist
retailers.
A system separator (check valve) prevents the
backlow of water and detergent into the drinking
water pipeline.
• Employ an ordinary garden hose for the water
intake and ensure sufficient length.
Assembly
Risk of injury!
If the high-pressure cleaner is improperly assem-
bled, this can result in injury or damage
• Assemble the high-pressure cleaner properly and
completely before first use.
• Never plug the mains plug into the power outlet
before completing the assembly.
Fit transport handle, cable winding cleat and
lance holder (Fig. C).
• Slide the transport handle (1) into the guide on the
top of the high-pressure
place with the screws (8). Use a Phillips screwdri-
ver for this (not included in the delivery).
• Push the cable cleat (3) into the side recess on the
high-pressure cleaner.
• Push the lance holder (6) into the rear recess until
it latches into place.
Fit the adapter for the water supply (Fig. D)

(see Operation).
High-pressure hose (11) and spray gun (10):
• Push the high-pressure hose (11) into the connec-
tion of the spray gun (10) until it latches into place.
• To remove the high-pressure hose (11), press the
button (A) and pull the high-pressure hose (11)
out of the spray gun (10).
Using the extension piece (9) and cleaning agent
container (13) with the spray gun (10):
• Using a little force, push the extension piece (9)
or the cleaning agent container (13) into the spray
gun (10) and turn it until it latches into place.

The diameter of the supply hose should be at least
12.7 mm (1/2").
9. Operation
Observe the regulations for the use of a system
separator.
• Open the water tap fully.
Do not operate the high-pressure cleaner with a
closed water tap. Running dry will damage the
device.
Switching on/off and handling the spray gun (Fig.
