The following procedure must only be performed
i
by a Titan Authorized Service Center.
The components of the pressure switch must be
i
properly reassembled and adjusted in order for
the pump to operate at the correct maximum
pressure.
Perform this procedure using pressure gauge P/N 0521229.
1. Make sure the knob bottom (1) is installed in the pressure
switch (2).
2. Viewing from the top, turn the knob bottom (1) counter-
clockwise as far as the teeth inside the pressure switch will
allow.
If the stop (3) on the pressure switch prevents the
i
knob bottom from continuing to turn, remove
the knob bottom, re-orient it on the teeth and
continue to turn it counterclockwise until it stops.
3. Re-orient the knob tab against the pressure switch tab
stop.
4. Replace the front cover and secure with the three screws.
5. Replace the pressure control knob into the knob bottom
but do not secure with the screw. Turn the knob fully
clockwise to maximum.
6. Connect the pressure gauge to the outlet fitting.
7. Connect a high-pressure hose and gun to the pressure
gauge.
8. Using water as a media, follow the steps in section 4.4. It
is not necessary to attach a spray tip to the gun. Leave the
pressure set to maximum.
9. The sprayer should now be pressurized at maximum
pressure. The pressure gauge should be reading between
193-207 bar.
10. If the pressure reading is below or above this reading, the
set screw down inside the pressure switch will have to be
adjusted. Adjust it per the guidelines below using a long
hex wrench.
a. If the pressure reading is below 193 bar, turn the set screw
b. If the pressure reading is above 207 bar, relieve pressure by
