SV- Safety Valve Operation

Safety valve is a system to protect the machine from over pressure. Over pressure occurs
when nozzle size is wrong or the nozzle is chocked. Another possible cause is the unloader
setting is wrongly set. When machine is over pressurized, the safety valve will start to open
and excess water is dumped. The setting of the safety valve system is factory set, do not try
to reset them.
