operate the cleaner for more than 1-2 minutes with
the gun closed as this could damage the seals.
● Protect the cleaner from freezing during the winter.
GB
● Do not obstruct the ventilation grilles during opera-
tion.
● The cross-section of any extension cables used
must be proportional to their length, i.e. the longer
the extension cable, the greater the cross-section;
cables with a protection level of "IPX5" must be
used.
● Position the cleaner AS NEAR POSSIBLE to the wa-
ter supply.
● The packaging is easily recyclable, and must be dis-
posed of in compliance with the regulations in force
in the country of installation.
● Use the cleaner only with accessories and replace-

of original accessories and replacement parts will
ensure safe, trouble-free operation.
● The cleaner must be used standing on a secure, sta-
ble surface.
● Avoid unintentional fi ring of the trigger. Do not carry
the lance/ trigger assembly with your hand over the
trigger. Always use the trigger lock mechanism.
● Ensure that the safety lock on the trigger is used,
when you have stopped using the pressure washer
to prevent accidental operation. (fi g 5)

valve. When the gun trigger is released, the safety
valve opens and the water recirculates through the
pump inlet.
