Servicing The Fluid Section; Repacking The Fluid Section - Titan IMPACT 1040 Notice D'utilisation

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.
3. Turn the pump off and unplug the unit.
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!
4. Remove the return hose from the clamp on the siphon tube.
5. Unscrew the siphon tube/siphon set from the foot valve.
6. Loosen and remove the high-pressure hose from the nipple
on the back of the upper housing of the fluid section.
Servicing the Valves
The design of the 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. Loosen and remove the foot valve
housing from the lower housing.
2. Clean out any debris in the foot
valve housing and examine the
housing and the foot valve seat.
If the seat is damaged, reverse or
replace the seat.
3. Using two wrenches, hold the
upper housing at the wrench flats
with one wrench and loosen the
lower housing with the other. Remove the lower housing.
4. Using a 3/8" hex wrench, loosen and remove the outlet valve
retainer 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.
5. Clean out any debris and examine
the retainer and outlet valve seat.
If the seat is damaged, reverse or
replace the seat.
6. Remove, clean, and inspect the
outlet valve cage and outlet valve
ball. Replace if they are worn or
damaged.
7. Reassemble the valves by reversing
the steps above.
NOTE: During reassembly, make sure the Viton o-rings and
the PTFE back-up rings between the upper housing
and lower housing as well as between the lower
housing and the foot valve housing are lubricated
with grease and in position.
