Problem
A. The unit will not run.
B. The unit will not prime.
C. The unit will not build or
maintain pressure.
D. Fluid leakage at the upper end
of the uid section.
E. Excessive surge at the spray
gun.
F. Poor spray pattern.
G. The unit lacks power.
Cause
1. The pressure is set too low.
2. Faulty or loose wiring.
3. The gas tank is empty.
1. The PRIME/SPRAY valve is in the SPRAY
position.
2. Air leak in the siphon tube/siphon set.
3. The pump lter and/or inlet screen is
clogged.
4. The siphon tube/siphon set is clogged.
1. The spray tip is worn.
2. The spray tip is too large.
3. The pressure control knob is not set
properly.
4. The pump lter, gun lter, or inlet screen is
clogged.
5. Material ows from the return hose when
the PRIME/SPRAY valve is in the SPRAY
position.
6. Air leak in the siphon tube/siphon set.
7. There is external uid leak.
8. There is an internal uid section leak
(packings are worn and/or dirty, valve balls
are worn).
9. Worn valve seats
1. The upper packings are worn.
2. The piston rod is worn.
1. Wrong type of airless spray hose.
2. The spray tip worn or too large.
3. Excessive pressure.
1. The spray tip is too large for the material
being used.
2. Incorrect pressure setting.
3. Insufcient uid delivery.
4. The material being sprayed is too viscous.
1. The pressure adjustment is too low.
Solution
1. Turn the pressure control knob clockwise to supply
power to the unit and increase the pressure setting.
2. Inspect or take to a Titan authorized service center.
3. Fill the gas tank.
1. Rotate the PRIME/SPRAY valve clockwise to the
PRIME position.
2. Check the siphon tube/siphon set connection and
tighten or re-tape the connection with Teon tape.
3. Remove the pump lter element and clean. Remove
the inlet screen and clean.
4. Remove the siphon tube/siphon set and clean.
1. Replace the spray tip following the instructions that
came with the spray gun.
2. Replace the spray tip with a tip that has a smaller
orice following the instructions that came with the
spray gun.
3. Turn the pressure control knob clockwise to increase
the pressure setting.
4. Remove the pump lter element and clean. Remove
the gun lter and clean. Remove the inlet screen
and clean.
5. Clean or replace the PRIME/SPRAY valve.
6. Check the siphon tube/siphon set connection and
tighten or re-tape the connection with Teon tape.
7. Check for external leaks at all connections. Tighten
connections, if necessary.
8. Clean the valves and service the uid section
following the “Servicing the Fluid Section” procedure
in the Maintenance section of this manual.
9. Reverse or replace the valve seats following the
“Servicing the Fluid Section” procedure in the
Maintenance section of this manual.
1. Repack the pump following the “Servicing the Fluid
Section” procedure in the Maintenance section of this
manual.
2. Replace the piston rod following the “Servicing the
Fluid Section” procedure in the Maintenance section
of this manual.
1. Replace hose with a minimum of 50’ of 3/8”
grounded textile braid airless paint spray hose.
2. Replace the spray tip following the instructions that
came with the spray gun.
3. Rotate the pressure control knob counterclockwise to
decrease spray pressure.
1. Replace the spray tip with a new or smaller spray tip
following the instructions that came with the spray
gun.
2. Rotate the pressure control knob to adjust the
pressure for a proper spray pattern.
3. Clean all screens and lters.
4. Add solvent to the material according to the
manufacturer’s recommendations.
1. Rotate the pressure control knob clockwise to
increase the pressure setting.
