Troubleshooting

7.1 General
Consult the Holmatro dealer if the listed solutions do not give the desired result, or in case of other
problems. For malfunctions or repair, always specify the model and serial number of the equipment.
7.2 The air flows through the regulator without any control
/i
Possible cause
The O-ring between the compressed air bottle and
the pressure regulator is missing.
The compressed air bottle valve is opened too fast
and the valve is stuck.
7.3 Poorly or constantly fluctuating air flow through the regulator
/i
Possible cause
Fouling in the valve. The sintered filter element in
the connection valve can become loose due to
releasing the threaded nipple. Then the nipple
vibrates and releases dust particles.
