PROBLEM
The piston does not slide easily and there is noise
between the pump tube and the piston.
CAUSE SOLUTION
There is no lubrication between the pump
tube and the piston sleeve.
Check the piston sleeve. If it is worn-down
replace it and grease it.
The pump system leaks. The antenna does not seal correctly in
the seat of the pump tube.
Replace the seal.
Lubricate before reaassembling.
Shut-off leaks after releasing the handle. The O rings of the shut-off plunger are
worn-down or swollen.
Replace and grease the new O rings and
plunger.
The sprayer is pressurized but there is no flow when
pressing the shut-off handle.
The pump tube is not tight enough.
Loosen the hose clamp and check if the hose
or the tank outlet are clogged and if so,
proceed to unclog them with pressurized air
or water.
Although the sprayer is being pumped vigorously it does
not build pressure.
The hose is clogged.
Tighten the tube and grease the O ring.
