regular basis (suggestion: every month for machines in regular use, every three
months for machines used intermittently). Using the machine with the incorrect
nozzle size or worn nozzle will VOID WARRANTY and can be DANGEROUS to
operator.
Pump Maintenance
Changing Pump Oil
Checking the oil level:
The pump is delivered complete with oil, with the characteristics stated on the
data plate. When changing the oil, use oil suitable for conditions in the operating
environment. The correct lubricating oil viscosity depends on the external
temperature. Use the graph to select the degree of viscosity best suited to the
temperature of use.
NOTE: When changing pump oil, use only high quality non-detergent oil. Use no
special additives.
Change oil after first 50 hours of operation and then every 200 hours of operation or
every 3 months of regular use, whichever occurs first.
