Tighten securely with wrench.
5.Place the cam base over the valve housing
assembly. Lubricate the cam base with grease and
line up the cam with the pump block.
6.Line up the hole on the valve stem with the hole in
the valve handle.
7.Insert the groove pin into the valve handle and
through the valve stem to secure the valve handle in
position.
Servicing the Fluid Section
Use the following procedures to service the valves and
repack the fluid section. Perform the following steps
before performing any maintenance on the fluid
section.
1.Loosen and remove the four front cover screws.
Remove the front cover.
2.Stop the sprayer at the bottom of its stroke so that
the piston is in its lowest position.
Turn off and
unplug the sprayer.
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. Always unplug the
sprayer before servicing!
3.Unscrew the return hose assembly from the pump
block.
4.Remove the retaining clip that holds the suction set
in the foot valve. Pull the suction set out of the foot
valve.
5.Tilt the pump back for easy access to the fluid
section.
Servicing the Valves
The design of Titan's fluid section allows access to the
foot valve and seat as well as the outlet valve and seat
without completely
disassembling the fluid section. It is possible that the
valves may not seat properly because of debris
stuck in the foot valve seat or outlet valve seat. Use
the following instructions to clean the valves and
reverse or replace the seats.
1.Using a wrench, loosen and remove the foot valve
housing from the pump block.
2.Clean out any debris in the foot valve housing and
examine the valve housing and seat. If the seat is
damaged, reverse or replace the seat.
3.Using a 3/8" hex wrench, loosen and remove the
outlet valve housing from the piston rod.
NOTE: Always service the outlet valve with the
piston rod attached to the pump. This will
prevent the piston rod from rotating during
disassembly of the outlet valve.
