TRIGGER VALVE MAINTENANCE
The filter in the trigger valve can be removed as shown and cleaned.
The seals in the trigger valve should be inspected and replaced if the valve is leaking
or fails to shut off completely. Spare seals are provided with each sprayer. There are
two seals which may need replacing.
To replace the o-ring seal on the plunger, first remove the trigger handle by removing
the locking pin. Using a pair of piers to grasp the top of the plunger remove it as
shown and replace the o-ring.
To replace the shut off seal, remove the spring retention cover and withdraw the
spring and seal. The seal can be easily replaced if necessary.
With time the spring tension on the trigger valve may become weakened. If this
happens fit the additional spacer provided with each sprayer.
