Feed Pumps
Keep the packing nut/wet-cup half filled with Graco
Throat Seal Liquid (TSL
™
) or compatible solvent to help
prolong packing life.
Adjust the packing nut weekly so it is just tight enough to
prevent leakage. Use a spanner wrench or a 0.25 in.
(6.3 mm) diameter rod to tighten the nut. Do not
over-tighten.
Never leave the pump or hoses filled with water or air.
To help prevent corrosion, flush the water and all air out
of the system and leave it filed with mineral spirits or an
oil-based solvent.
Solvent Pump
Keep the wet cup half filled with Graco Throat Seal
Liquid (TSL

Agitators
After the first 100 hours, or two weeks of operation,
change the gear reducer oil. After that, change the oil
every 2500 hours, or six months (whichever comes first)
of operation under normal conditions. More frequent oil
changes are needed under severe operating conditions
or in atmospheres containing excessive moisture or
abrasives. See your agitator manual for the oil changing
procedure.
If the air motor is operating sluggish or inefficiently, flush
the air motor (see your agitator manual).
Every 2500 hours, or six months (whichever comes first)
of operation, inspect the bearing block (see your agitator
manual).
