Starting
-Dirt in the feed water could lead to the
appliance being damaged. To avoid this
risk, we recommend fitting a filter with
3/4" connection .
-If you are using an extension cable, it
should always be completely unwound
from the cable drum and have a sufficient
cross-sectional area (10 m = 1,5 mm²,
30m = 2,5 mm²).
Operation with high pressure
-The appliance is equipped with a pressu-
re-operated switch. The motor starts only
if the lever of the gun is pulled.
-The safety ratchet does not lock the lever
of the gun during operation but only
prevents it from opening unintentionally.
Suction operation
-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.
Operation with Detergent
-We recommend that you use detergent
sparingly for the sake of the environment.
Observe the recommended dosage on
the detergent label.
-This machine has been designed for use
with cleaning detergent supplied or re-
commended by the manufacturer. The
use of other cleaning detergents may af-
fect the operation of the machine and void
the warranty.
-We recommend the following cleaning
methods:
Step 1: Loosening dirt
Spray on detergent sparingly and allow
to react for a short time.
Step 2: Removing dirt
Spray off the loosened dirt with the
high-pressure spray.

Switching Off
-After using a detergent, the appliance
should be rinsed clear. To do this, sus-
pend the detergent suction hose in a con-
tainer of clean water, and run the pump for
approx. 1 minute.
-Pull the trigger until there is no more pres-
sure in the appliance, and secure the
trigger with the safety ratchet against
unintentional opening.
-Frost will destroy an appliance which has
not been completely emptied of water.
