The appliance should only be connected to a mains power supply equipped with an adequate earth connection and a differential security breaker (30 mA) to cut off the electricity supply in the instance of a short circuit. The cross-section of the extension cable should be proportionate to its length; the longer it is, the greater its cross-section should be. If the motor fan is turning anti-clockwise, exchange two of the three phase wires (L1, L2, L3) in the electrical plug. 3) Depress the gun trigger for a few seconds and start up the appliance using the starter device (ON/1). TSS models - In TSS models with automatic delivery flow cut-off system: - when the gun trigger is released the dynamic pressure automatically cuts out the motor (see fig. 4); - when the gun trigger is depressed the automatic drop in pressure starts the motor and the pressure is restored after a very slight delay; - if the TSS is to function correctly all gun releasing and depressing operations must be performed at intervals of less than 4-5 seconds.
