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.
WARNING
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.
4. Clean out any debris and
examine the valve housing and
seat. If the seat is damaged,
reverse or replace the seat.
5. Remove, clean, and inspect the
upper cage and upper ball. Replace if they are worn or
damaged.
6. Reassemble the valves by reversing the steps above.
