*1Whenever setting pressure , make sure the full cut-off pressure never exceeds the maximum intermittent pressure.
*2Care should be taken in cases of used at a higher pressure than the rated pressure, because operating terms may be restricted. Consult factory or PROPISTON sales representative for further information.
