Agitator Blades
Regularly check the agitator for dried material buildup.
Clean using a rag soaked in solvent that is compatible
with the spray material and the surfaces being cleaned.
Additionally, extra precautions need to be taken if using
lower conductive materials (<1000 pS/m) such as:
•
Avoid stirring/mixing at high speeds.
•
Avoid insoluble mixtures.
•
When possible, increase the material conductivity
with additives.
•
Use liquids with a high conductivity (>1000 pS/m)
Lubricate the Air Motor
(Model 236629 Only)
If an air line lubricator (AL) is not installed, the air motor
must be manually lubricated every 8 hours. Lubricate
the agitator air motor by placing 10 - 20 drops of SAE
#10 light oil in the motor's air inlet. Oil must have an
auto-ignition rating of (482°F) 250°C or greater. Run the
agitator for about 30 seconds.
Clean the Air Intake Check Valve
The air intake check valve (33) allows make-up air to
enter the closed drum as fluid is drawn out through the
agitator outlet port. See F
. 8. The air intake check
valve should be inspected and cleaned every 2000
operating hours or when there are any signs of the drum
beginning to collapse as fluid is drawn out.
Pump priming problems can indicate a plugged air
intake check valve. Paint overspray in the air can be
drawn into the valve and cause the ball to stick in the
closed position.
To clean the air intake check valve
1.
Remove the seat (33) and ball (34). See Parts,
page 18.
2.
Clean the parts with compatible solvent, and
reassemble the valve.
3.
Insert the ball (34), and tighten seat (33) until just
snug.
NOTE: The seat should not be flush with the elbow (32).
Installing the seat too tightly could jam the ball against
the seat.
Materials can become electrostatically charged when
stirred or blended. To prevent fire and explosion,
ground equipment and do not allow material buildup
on the agitator. Dried material could allow static build
up and interfere with grounding.
NOTICE
Not lubricating the air motor will cause air motor failure.
