Checking the safety valve
1. Ensure that you check that the safety valve (11) is in
working order every day that the unit is in operation.
To check the valve, first pressurise the tank to close to
maximum pressure (Fig. 31).
2. Hold the ring on the safety valve (11) and pull it outwards.
Air should discharge from the valve (Fig. 32).
3. When the ring on the safety valve (11) is released the air
discharge should stop (Fig. 33).

WARNING!
Take care when discharging air through the safety valve, drainage
screw or the air outlet. The discharged air can cause dust, stones or any other
foreign particles to be blown through the air at high pressure.
IMPORTANT!
Before cleaning your air compressor or carrying out any maintenance
procedure, make sure that the motor is off and the tool disconnected from the
power supply to prevent accidental starting.
IMPORTANT!
Wait until the compressor has completely cooled down.
Risk of burns!
WARNING!
Do no use the compressor if the safety valve does not work as
described.
WARNING!
Wear safety glasses and keep your face away from the safety valve
when carrying out this check. Air will be discharged at a high pressure.
