1. Lubricate the metering rod ports in the oil cup

retaining block and fill the spool valve ports with

compatible lubricant. Consult with your material

supplier to select an acceptable lubricant. Regularly

verify that lubricant is present.

2. Perform Ratio Check, page 26.

3. Install mixer and shroud.

4. Pressurize the A and B material feed systems con-

nected to the metering valve to prime the system.

See page 3 for maximum inlet feed pressures.

5. 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.

NOTICE

Testing has shown that failure to lubricate the valve

will significantly reduce seal life.
