Safety Shut-Off Switch

The safety shut-off switch is pre-set by the factory to shut
down the sprayer to prevent over-pressurization. Do not
attempt to adjust or tamper with the safety shut-off switch.
Contact an authorized service center if this setting requires
adjustment.
i
The safety shut-off switch should be set to shut
down the sprayer between 3200 – 3300 PSI.
6.4 High-pressure hose
Inspect the high-pressure hose visually for any notches or
bulges, in particular at the transition in the fittings. It must be
possible to turn the union nuts freely.
The risk of damage rises with the age of
i
the high-pressure hose. Titan recommends
replacing high-pressure hoses after 6 years.

Replacing the relief valve

Perform the following procedure using relief valve
replacement kit P/N 759-380.
Before proceeding, follow the Pressure Relief
Procedure outlined previously in this manual.
Additionally, follow all other warnings to
reduce the risk of an injection injury, injury
from moving parts, or electric shock.
1. Pry off the retaining clip (1) from inside the recessed
portion of the valve knob (2). Remove the valve knob.
2. Slide the cam (3) off of the stem/ball assembly (4).
3. Using a wrench, remove the hex nut (5) from the pump
head (6).
4. Remove the star washer (7), spring (8), and stem/ball
assembly (4) from the pump head.
5. Using a 7/32" (6 mm) hex wrench, remove the stem/ball
assembly seat (9) from the pump head.
6. Tighten the new stem/ball assembly seat (9) into the
pump head (6). Use a 7/32" (6 mm) hex wrench. Torque
to 6-8 ft.-lbs.
7. Apply a light coating of hydraulic oil around the o-ring
on the new stem/ball assembly.
8. Push the stem/ball assembly into the stem/ball
assembly seat in the pump head.
9. Place the new spring and star washer around the stem/
ball assembly.
10. Slide the new hex nut onto the stem of the stem/ball
assembly, thread it onto the pump head, and tighten
with a wrench. Torque the nut to 12-14 ft.-lbs.
11. Apply a light coating of grease to the top of the cam.
12. Slide the new cam onto the stem of the stem/ball
assembly and over the hex nut. The design of the cam
will allow the hex nut to fit inside the cam, causing the
cam to lock in position.
Position the cam on the hex nut so that the tab
i
(fig. 21, item 1) on the side of the cam is as close
to the 12:00 position as possible.
