splashes (IP 55).
5.9.2 Sequence of steps for using the high pres-
sure cleaner with the TRONIC device:
1 - Fit the accessories (lance and hose) to
the pressure cleaner and then connect the
cleaner to the water supply.
2 - Connect the plug to the electrical mains.
3 - Press the ON button on the control
panel. The pressure cleaner will start up
and then stop after 5 seconds. FIG. 5G
4 - Squeeze the gun trigger to activate the
pressure cleaner and commence was-
hing. The green and yellow LEDS on the
control panel should be on, indicating
POWER and PUMP respectively.
5 - Release the gun trigger to interrupt ope-
ration; water will stop coming out of the
lance, but the motor will keep running.
After ~ 5 seconds the motor will stop and
the yellow LED light will go off. During this
5-second delay the operator may resume
work straight away .
6 - Squeeze the gun trigger again to restart
the motor. Once the trigger is squeezed it
takes ~ 1 second for the water to come out
under pressure. This is normal and is the
amount of time it takes for the pump to fill
the delivery hose with water under pres-
sure.
INDICATION LIGHTS ON THE CONTROL PANEL
DURING OPERATION:
GREEN POWER LED ON: Machine in standby
mode and ready for operation by squeez-
ing the gun trigger.
YELLOW PUMP LED ON: Machine working with
pump running.
5.9.3 For optimum service from the TRONIC
appliance, the gun should NOT be opened
and closed at intervals of less than 4-5
seconds.
5.10 USE AND CHARACTERISTICS OF TSS
MODELS FIG.5H with automatic delivery
flow cut-off:
- when the trigger is released, the dynamic
pressure automatically cuts out the motor.
- when the trigger is pressed the pressure
drop automatically starts the motor and
the pressure is restored with a very slight
delay.
- For correct operation of the TSS, once the
trigger has been released it must not be
pressed again for at least 4÷5 seconds.
For correct use of the TSS model cleaner,
do not leave the unit in automatic cut-off
status for more than 10 min.
