NOTE:
Fill the A and B pump packing nuts with TSL.
Also, always leave some type of fluid, such as
solvent or oil, in the system to prevent scale
build up. This build up can flake off later. Do not
use water.
If machine is set up with a remote mix manifold,
the A and B hose can be disconnected from the
mix manifold, and secured in back of each hop-
per for circulation of flush solvent.
Change the flush solvent at least once until it

Always keep the A side and B side flush solvent
