1.
Lubricate the metering rod port in the oil cup retain-
ing block and fill the spool valve ports with compati-
ble lubricant such as mesamoll or silicone oil.
2.
Pressurize the feed systems connected to the
metering valve to prime the system. See
on page 21 for maximum inlet feed pressure.
3.
Dispense several full stroke shots until material is
air-free and has good shut-off at the nose.
NOTE:
Very viscous, compressible materials may con-
tinue to droll after system is primed. Reduce flow rate as
required to produce air-free dispense.
NOTE:
Very thin materials may require tilting the valve
greater than 45 degrees and dispensing shots until
material is air-free. Remove oil from cups before pro-
ceeding.
