8 Maintenance and repair
WARNING Always switch off the mains disconnecting switch when leaving the machine
unattended • Always remove the plug from the mains plug socket before carrying out mainte-
nance work or cleaning of the machine.
Carry out only the maintenance operations described in the operating instructions. To ensure
machine safety: use only original Gerni spare parts. Do not make any technical modifications
to the high-pressure cleaner. Ensure that the machine is regularly serviced by authorized Gerni
dealers in accordance with the maintenance plan. Failure to do so will invalidate the warranty.
CAUTION High-pressure hoses, fittings and couplings are important for the safety of the clean-
er. Use only high-pressure spare parts approved by Gerni! • If the supply cord is damaged it
must be replaced by the manufacturer, its service agent or similarly qualified persons to
prevent hazards.
