Daily Maintenance
Keep displacement pump packing nut/wet cup lubri-
cated with Airlessco Throat Seal Oil at all times. The
TSO helps protect the packings and rod. Inspect the
packing nut daily. If seepage of paint into the packing nut
and/or movement of the piston upward is found (while
not spraying), the packing nut should be tightened just
enough to stop leakage. Overtightening will damage the
packings and reduce the packing life.
Cleaning a Clogged Tip
1. Relieve Pressure, page 6.
2. Clean the front of the tip frequently (with toothbrush
only) during the day to keep material from building
up and clogging the tip.
3. To clean and clear a tip if it clogs, refer to the sepa-
rate instruction manual received with your gun and
nozzle.
4. Clean a clogged standard flat tip only after the tip is
removed from the gun.
Reducing Clutch Wear
1. The first 50 feet of airless spray hose should be 3/8”,
the larger diameter works as a pulsation damper
and saves unnecessary cycling the clutch. A mini-
mum of 100 feet of hose should be used.
2. Adjust the Engine Speed and Pump Pressure. First
set the throttle lever to the maximum RPM setting
(fully left). Trigger the gun onto a test paper to check
the spray pattern and atomization. Adjust the Pres-
sure Control Knob until you get a good pattern.
Reduce RPM of engine to support pressure without
laboring engines.
Regular Maintenance
1. Always stop the pump at the bottom of its stroke
when you take a break or at the end of the day. This
helps keep material from drying on the rod, damag-
ing the packings.
2. Keep the displacement pump packing nut/wet cup
1/3 full of Airlessco Throat Seal Oil (TSO) at all
times. The TSO helps protect the packings and rod.
3. Lubricate Connecting Rod Pin every 3 months.
