Preventative 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
Note
For over night shutdown, stop pump at
bottom of its stroke to prevent fluid from
drying on exposed displacement rod
and damaging throat packings. Follow
Pressure Relief Procedure, page 14
.
1. Flush. See
Flush, page 15
.
2. Relieve pressure. See
Pressure Relief Procedure, page 14
.
3. Check packing nut (S ). 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
displacement rod. Never leave water or water-based
fluid in the pump overnight. First, flush with water
or a compatible solvent, then with mineral spirits.
Relieve the pressure, but leave the mineral spirits in
the pump to protect the parts from corrosion.
Cart Maintenance
Periodically lubricate the axle between points A and
B with lightweight oil.
Keep the cart clean by wiping up spills daily, using a
compatible solvent
