Preventive Maintenance
Schedule
The operating conditions of your particular system
determine how often maintenance is required. Establish
a preventive maintenance schedule by recording when
and what kind of maintenance is needed, and then
determine a regular schedule for checking your system.
Daily Maintenance
1. Flush. See Prime/Flush, page 14.
2. Relieve pressure. See Pressure Relief Procedure,
page 13.
3. Check packing nut (S, F
IG
. 1). Adjust packings and
replace TSL as necessary. Torque to 25-30 ft-lb
(34-41 N•m).
4. Drain water from air filter.
5. Clean suction tube using a compatible solvent. It is
recommended that you clean the outside of the
sprayer using a cloth and compatible solvent.
6. Check hoses, tubes, and couplings. Tighten all fluid
connections before each use.
7. Clean fluid line filter.
Corrosion Protection
Always flush the pump before the fluid dries on the dis-
placement rod. Never leave water or water-based fluid in
the pump overnight. First, flush with water or a compati-
ble solvent, then with mineral spirits solvent (also called
white spirit). Relieve the pressure, but leave the mineral
spirits solvent (also called white spirit) in the pump to
protect the parts from corrosion.
Cart Maintenance
Periodically lubricate the axle between points A and B
with lightweight oil. See F
IG
. 4.
Keep the cart clean by wiping up spills daily, using a
compatible solvent.
NOTE: For overnight shutdown, stop pump at
bottom of its stroke to prevent fluid from drying
on exposed displacement rod and damaging
throat packings. Follow Pressure Relief Proce-
dure, page 13.
