PROBLEM
CAUSE
SOLUTION
The shut-off valve does not close after
releasing the trigger.
The plunger O-rings are worn out or
swollen.
Replace them and lubricate the plunger
with the new O-rings.
The shut-off valve does not function
when depressing the trigger.
The nozzle are blocked.
Clean the nozzle.
Moving the pump handle becomes
very difficult.
The internal part of the cylinder are dirty,
so the piston ring can not run smoothly,
or the piston ring grew because the
material used to apply is very aggressive.
Open the cylinder according to the method
mentioned in point 5.1 to check if its dirty and
clean, compare the piston ring to a new one
to see if it grew, if it did change immediately.
The tank collapses “it shrinks”.
The cap gasket is not letting air through.
Clean the gasket and lubricate, also clean
the cap and assembly again.
While working there is leakage between
the cap and the tank .
The cap gasket is not lubricated.
Lubricate or replace according to the
diagnosis.
While working there is some leakage
from the cylinder.
The cylinder can be worn out from the
inside or the piston rings damaged
Replace.
While working, the sprayer does not
generate pressure.
The gaskets are dirty, dry or blocked.
Replace.
While pressuring the tank with the lever,
when you stop it goes up and stays there.
The gasket that is inside the cylinder is
blocked or stayed open.
Inspect the cylinder, clean, adjust and put
back in place.
While working, the pressure lasts very
little time.
The pressure chamber is filled with water
because the gaskets are not working.
Take the water out of the sprayer and
replace the gaskets.
The sprayer builds low or no pressure.
Check valve in the pump have become
stuck and/or there is an air lock in the
unit.
Release pressure by keeping flow control open
and pumping several times. Disassemble and
force seals open by hand if step one does not
work.
Replace O-rings and seals, replace pressure
chamber if there is no improvement, lubricate
and reassemble.
The sprayer does not hold pressure or tank
leaks at pump connection.
The O-rings and check valve need replacing,
the pressure chamber has expanded or the
check valves are clogged with debris.
Tank leaks at hose connection.
Clamp is loose or damaged.
Replace clamp.
Module is leaking.
The Sealed module pump is damaged.
Replace module with part No. E505-155-C.
Tank leaks at pump and pressure chamber
connection.
The hose clamp is loose or the O-ring
is damaged.
Tighten the hose clamp, use part No. E501-021 to
replace the O-ring.
