Maintenance and Care
Every machine is only as reliable as maintenance is carried out.
In order to guarantee reliability and trouble free operation of the
machine, it is of vital interest to follow the instructions below:
If the required maintenance intervals are disregarded, warranty will
expire.
High Pressure Pump
First oil change after 50 operating hours, further oil changes after every 500 operating
hours, minimum once per year. In case the oil becomes milky due to condensate
formation, stop the machine immediately and carry out oil change. If this happens
repeatedly, arrange replacement of all pump seals by qualified personnel.
For OERTZEN high pressure pumps only OERTZEN OSHP special pump oil
to be used, as otherwise you will loose your right to claim under guarantee.
OERTZEN OSHP special pump oil is available from your OERTZEN dealer.
