NOTE: If the pump is not immersed in fluid, fill the
wet-cup 1/3 full with Graco Throat Seal Liquid (TSL)
or a compatible solvent. The TSL prevents fluid from
drying on the displacement rod and damaging the
pump packings. Check the tightness of the packing
nut/wet-cup weekly. Before adjusting, relieve

1.
Check the hydraulic fluid level before each use.
Add fluid as needed to the fill lines.
2.
Turn on the hydraulic power supply.
3.
Open the hydraulic return shutoff valve (N).
4.
Slowly open the hydraulic supply shutoff valve
(M).
5.
Run the pump slowly until all air is pushed out of
the lines and fluid is flowing smoothly.
6.
Close the spray gun. The pump will stall.
NOTE:
NOTE:
NOTE: Use the lowest pressure possible to get
the desired results. Higher pressures will cause
premature tip and pump wear.

NOTICE
Never allow the hydraulic fluid temperature
to exceed 130°F (54°C). The pump seals will
wear faster and leaking may occur at higher
temperatures.

Shutdown
To reduce the risk of overpressurizing your system,
which could cause component rupture and serious
injury, always shut off the hydraulic supply line
shutoff valve (M) first, and then the return line
shutoff valve (N).
Follow the Shutdown Procedure at the end of the
work shift and before you check, adjust, clean, or
repair the system.
1.
Flush the pump with water. See
.
2.
After flushing, flush the pump again with a
compatible solvent, such as mineral spirits.
3.
Follow the
Pressure Relief Procedure, page 12
.
4.
Always stop the pump at the bottom of its stroke
to prevent fluid from drying on the rod and
damaging the throat packings.
5.
Leave a coating of solvent in the pump and
hoses.

To help prevent corrosion of the pump, never leave
the pump filled with water or water-based fluids,
or air, during non-use.
