gering the spray pistol.
4. Dismount the backflow preventer. Water has to come
out of the drain opening () (max. 100ml) to ensure sepa-
ration of the potable water.
5. If this is not the case, try cleaning the BA valve or con-
tact your Nilfisk representative.
C6. Electrical connection
1. Observe safety instructions.
2. Put the plug into the electrical socket.
CAUTION!
• Before connecting devices with voltage changeover:
Check that the pre-selected voltage on the machine cor-
responds with the voltage of the electrical installation.
Otherwise the electrical devices of the machine can be
destroyed1).
• When using a cord reel: Unwind the cord completely.
• The cleaner may only be connected to a correctly in-
stalled electrical installation.
C7. Releasing the cable
1. Turn the cable hook (A).
2. Release the cable (B).

NOTE! The cleaner automatically switches off after more
than 5 minutes of inactivity. See specification for max.
suction height.
D3. Pressure regulation with Tornado Plus lance and Power-
SpeedVario Plus lance:
High pressure = clockwise (+)
Low pressure = anticlockwise (–)
D4. Pressure regulation with the FlexoPowerPlus nozzle head
and the PowerSpeedVario Plus lance: Twist cap of the
FlexoPowerPlus nozzle head:
High pressure = MAX.
Low pressure = MIN.(CHEM)
D5. Using cleaning agents: Cleaning agent can be drawn in
via the injector installed as standard only in low-pressure
mode:
1. Dilute cleaning agent according to the manufacturer‘s
instructions.
2. Tornado Plus lance and PowerSpeedVario Plus lance1):
Set pressure regulation on spray lance to low pressure
(–), or FlexoPowerPlus nozzle head1):
Turn cap of the FlexoPowerPlus nozzle head towards
“CHEM“ up to the stop.
3. The intaken volume of cleaning agent can be regulated
by turning the metering valve.
4. Select tank A by turning the merering valve on “A-side”.
