This product contains a light source of energy efficiency class:
Possible cause
• Pneumatic connections are loose�
• Sandblasting hose worn�
• The connecting pressure at the ex-
ternal air connection (15, Fig� 1) is
too small�
• Outer pressure regulator on the
maintenance unit is altered (fixing
screw is loosen)�
• A small amount of leakage is always
present at the control valves, thus al-
lowing (a minimum) of air to escape�
• Continue to turn the tank selection
switch whilst activating the foot
switch at the same time�
Corrective action
• Inspect the pneumatic connections for correct seating�
• Replace the sandblasting hose�
• Increase the external connecting pressure at a min� of
5 bar� The external connecting pressure is displayed
on the manometer (8, Fig� 1)�
• Turn the inner pressure regulator clockwise until stop�
Activa e foot pedal and set the pressure regulator on
the maintenance unit at 5 bar (see manometer)�
• This is not a fault, but instead is the result of a pres-
sure release opening which must not be blocked�
• Only turn the tank selection switch when the foot
switch is not activated�
