Solvent Push Feature - Graco ProMix 2KS Operation Manuals

Solvent Push Feature

The Solvent Push feature enables the user to save
some mixed material by pushing it out to the gun with
solvent. The quantity saved is 50% of the potlife volume
entered in Advanced Setup Screen 1 on page 37. If
there are 2 guns, the smaller potlife volume is used.
Solvent Push requires an accessory solvent meter (MS).
