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 fluid 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 filter 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 filter, gun filter, or inlet screen is
clogged.
5. Material flows 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 fluid leak.
8. There is an internal fluid 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. Insufficient fluid 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 PTFE tape.
3. Remove the pump filter 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 orifice
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 filter element and clean. Remove the
gun filter 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 PTFE tape.
7. Check for external leaks at all connections. Tighten
connections, if necessary.
8. Clean the valves and service the fluid 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 filters.
4. Add solvent to the material according to the
manufacturer’s recommendations.
1. Rotate the pressure control knob clockwise to increase
the pressure setting.
