Replacing The Gears; Replacing The Pressure Switch / Transducer - Titan IMPACT 340 Notice D'utilisation

replacing the Gears

NOTE: It is recommended that the following procedure be
performed by a Titan authorized Service center.
1. Perform the Pressure Relief Procedure and unplug the sprayer.
2. Loosen and remove the four motor cover screws (1). Remove
the motor cover (2).
NOTE: The ON / OFF switch (3) is housed inside the
motor cover. In order to remove the motor cover
completely, you must disconnect all of the wires at
the rear of the switch. Note the position of the wires
before disconnecting.
3. On the back of the motor (4), disconnect the two wires (black
and red) coming from the circuit board (5). Remove the
ground wire from the motor housing.
4. Slide the motor baffle (7) off the rear of the motor.
5. Loosen and remove the four motor mounting screws (8).
6. Pull the motor (4) out of the pump housing (9).
7. Inspect the armature gear (10) on the end of the motor for
damage or excessive wear. If this gear is completely worn out,
replace the entire motor.
8. Remove and inspect the 2nd stage gear (11) for damage or
excessive wear. Replace if necessary.
9. If the armature gear (10) or 2nd stage gear (11) are damaged,
the pump housing (9) must be cleaned of any debris caused
by damaged gears.
10. Reassemble the pump by reversing the above steps.
NOTE: refill the gear box in the pump housing with five

replacing the Pressure Switch / Transducer

NOTE: It is recommended that the following procedure be
performed by a Titan authorized Service center.
NOTE: If the sprayer loses all pressure adjustment, or there
is paint leakage from the front of the sprayer, the
pressure switch and/or transducer may need to be
replaced.
1. Perform the Pressure Relief Procedure and unplug the sprayer.
2. Remove the screw (1) that secures the pressure control knob
(2) to the bottom of the pressure control knob (3). Remove
the knob (2).
3. Loosen and remove the three front cover screws (4). Remove
the front cover (5).
4. Remove the screw (7) from the side of the pressure switch.
Remove the bottom of the pressure control knob (3) from the
top of the pressure switch.
5. Remove the pressure switch assembly (6) from the top of the
transducer (8).
6. Unplug the pressure switch (6) from the wire connector (10).
ImPOrTaNT: Do not attempt to pull wires from the inside of the
pressure switch assembly. If the pressure switch wire connector
(10) is not exposed through the opening in the pump housing,
pull gently on the wires until the connector is shown through the
opening.
7. Check pressure switch continuity at the connector. If the
switch is bad replace with a new pressure switch assembly.
8. Inspect the transducer (8) for the presence of paint. If there is
paint, replace the transducer. If there is no paint, skip to step
9, below.
a. Using a wrench on the hex head of the transducer, loosen and
remove the transducer assembly.
b. Apply a generous amount of grease to the transducer O-ring (9).
Reinstall the transducer assembly and torque to 70-75 in-lbs.
9. Reconnect the pressure switch wires (refer to the electrical
schematic in the Parts List section of this manual).
10. Push pressure switch assembly (6) back onto the transducer
until it bottoms out on the transducer hex head.
11. Replace the screw (7) into the side of the pressure switch.
12. See "Resetting the Pressure Switch Timing", next page.
