2.9 Safety devices
Safety devices serve to protect the user and must not be suspended or circumvented in their function.
The high pressure cleaner has the following safety devices listed below:
● Pressure switches:
Device functions are switched on or off (safety functions) based on type of construction and intended use.
● Unloader valve and non-return valve:
The first serves to adjust the operating pressure and the second valve keeps the pump head depressurised when the trigger gun is deactivated.
● TSS system with pump-off delay:
After deactivating the trigger gun, the pump continues operation for approx. 30 s in the pressureless bypass mode (avoidance of too high pressure build-up in the pump); after 30 s the high pressure cleaner automatically switches into the stand-by mode.
● Total Switch-off:
Automatically switches the high pressure cleaner off in the event of prolonged interruption of operation or unused trigger gun for more than 20 minutes.
● Overload protection switch:
When the motor current load is too high the switch releases and the device is switched off.
● Mechanical arrest for trigger gun:
Prevents unintentional or unconscious activating the trigger gun.
