2. Pressurize the feed systems connected to the

metering valve to prime the system. See Technical

Data on page 29 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.
