Care and maintenance

DANGER
Risk of electric shock.
 Prior to all work on the appliance, switch off the ap-
pliance and pull the power plug.
High pressure hose
The high pressure hose is specially constructed with re-
inforced walls to handle water pressure up to 13 MPa
(1900 psi) - it can be easily damaged and should be
stored carefully.
 Do not kink.
 Do not drive vehicles over the hose.
 Do not expose the hose to sharp edges or corners.
Misuse will lead to ballooning or premature failure and
will invalidate warranty.
