Maintenance
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 displacement pump packing nut/wet cup 1/3
full of Airlessco Throat Seal Oil at all times. The
TSO helps protect the packings and rod.
3. Lubricate Connecting Rod Pin every 3 months.
Daily Maintenance
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.
Oil and Lubrication Instructions
Electric Motor Maintenance
Lubrication
The motor is supplied with pre-lubricated ball bearings,
lubricated for the life of the bearing.
Motor Brushes
Motor brushes need periodic inspection and replace-
ment as wear indicates. Brushes have an initial length of
1 and 1/4” and should be replaced when they are worn
to a length of 5/8”. Brush wear is greatly influenced by
individual application and it is recommended that brush
wear be checked at early intervals of operation in order
to determine future required inspection.
To change the brushes:
1. Unplug the machine.
2. Remove the cover over the motor.
3. Open the two covers at the rear of the motor.
4. Loosen the screw under the brush.
5. Pull out the wire.
6. Push the brush retainer clip in and withdraw.
7. Remove the worn brushes.
8. Install new brushes in the reverse order.
To increase brush life, new brushes (Part #301146 for
110 volt) need to have a run in period. After changing
brushes, set the machine for spraying. With a bucket of
Pump Conditioner and water, a 50’ 1/4” airless hose, air-
less gun and tip on unit, open the prime/pressure relief
valve and switch on. The pump will now prime. With
pump running in the prime mode, turn the pressure con-
trol knob to high pressure. (The pump has to cycle fast
with no pressure in the pump). Run the pump for 20 min-
utes and the brushes will be run in.
