● 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-

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)

pump inlet.
