Unscrew hose nut from tank and ensure that
the hose is pushed all the way into the tank up
to the ridge in the hose. Make sure the O-ring
is properly seated and not damaged. Tighten
the hose tank nut or replace the hose O-ring.
Troubleshooting
Problem Probable Cause Solution
The spray solution or
air leaks into the pump
cylinder.
The check valve on the bottom
of the cylinder is unable to seal
properly due to dirt, residue, or
damage.
Remove the pump assembly and examine
the check valve. Clean if dirty; replace if
necessary.
The hose leaks air at the
tank connection.
The tank nut is loose or the hose
insert O-ring is damaged.
There is a bad spray
pattern or low spray
volume.
The nozzle is clogged, the nozzle
is tightened too fat, or the
pressure is low in the sprayer.
There is a leak at the
tank opening.
The pump assembly is not sealed
tightly into the tank.
The Cylinder O-ring is damaged.
Thoroughly clean the pump cylinder
O-ring and surrounding area and apply
grease or petroleum jelly to the pump
O-ring.
Replace the O-ring. For spare parts,
call 1-800-253-4642.
Slowly turn nozzle counterclockwise to
ensure it is open. If still low spray volume,
remove the nozzle, the diffuser, and
clean. Remove the wand and clean. If the
wand cannot be unclogged, replace it or
repressurize the tank.
The nozzle leaks when
the flow control is closed
and/or the sprayer will
not stop spraying.
Make sure level is pulled all the way to
the off position. If problem persists and/or
lever continues to get stuck, completely
disassemble the flow control. Inspect all
components, clean, and lubricate all
seals, especially the white plunger inside
the flow control cap. If needed, replace
the flow control. Household petroleum
jelly can be used for lubrication.
The flow control is open because
the lever is locked in the on
position.
Fluid leaks from the
pressure relief valve.
Release the pressure by following the
“Releasing pressure from the Tank”
instructions in the Operation section.
The tank is over filled.
1. Remove pump assembly (D) from the tank (A).
See Fig. 1.
2. Unlock the pump handle and pull it out as far as
it will go.
3. With a flat blade screwdriver, push down on
the tabs on each side of the pump to release the locking
cap. See Fig. 2.
• Pull up and the handle and the plunger assembly
should come out of the pump cylinder.
• Spread a small amount of lubricant on the
outer edge of plunger gasket.
4. To reassemble, insert the plunger assembly into the
cylinder and snap the cap back into place
To keep the pump working smoothly and efficiently,
the plunger gasket needs to be lubricated often by
applying a lubricant, such as petroleum jelly, around
the outside of the plunger gasket.
Air leaks from the
pressure relief valve.
The pressure release valve is
stuck in the open position.
Turn the pressure release valve counter
clockwise until it clicks and reseats itself.
The tank is not
pressurizing.
The flow control cap is open.
The hose is not fully connected
to the tank.
The lid is not completely closed.
The flow control wand is not
properly assembled.
Ensure flow control cap is closed
completely.
See Problem #2 above.
Ensure lid is turned completely
clockwise.
Disassemble and reassemble all pieces
to flow control wand, ensuring they are
properly attached.
