WARNING
• Inadequate extension cords can be dangerous. If an extension cord is
used, it shall be suitable for outdoor use, and the connection plug has
to be kept dry and off the ground. It is recommended that this is ac-
complished by means of a cord reel, which keep the socket at least
60mm above the ground. Always unwind cord from the reels complete-
ly to prevent the power cord overheating.
• Disconnect the power cord from the power source by pulling the plug
only (do not pull or tug the power cord).
7 Safety devices
Thermal sensor: A thermal sensor protects the motor against overloading.
The machine will restart after a few minutes when the thermal sensor has
cooled.
Unloader valve: Unacceptably high pressure is fed back without residual
pressure via a bypass line into the intake line of the pump when the safety
device is tripped.
The unloader valve is set and sealed at the factory and must not be adjust-
ed.
Locking device on spray handle: The spray handle features a locking de-
vice. When the pawl is activated, the spray handle cannot be operated.
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
maintenance work or cleaning of the machine.
Carry out only the maintenance operations described in the operating in-
structions. To ensure machine safety: use only original UNITOR spare
parts. Do not make any technical modifications to the high-pressure clean-
er. Ensure that the machine is regularly serviced by authorized UNITOR
dealers in accordance with the maintenance plan. Failure to do so will in-
validate the warranty.
