RELEASING PRESSURE
1. To release pressure from the tank, turn the tank upside
down, and then squeeze the flow control lever until all the
air pressure is gone, or pull the pressure relief valve (13)
until all air pressure is gone.
2. If your sprayer is clogged and the pressure will not
release using the flow control, do the following:
a. Place a rag over the top of the sprayer and pump.
b. While firmly pushing down on the pump handle, slowly
turn counter-clockwise.
WARNING!
• ALWAYS RELEASE pressure in sprayer before servicing.
• NEVER leave pressurized sprayer unattended.
CLEANING
To prolong its life, clean the sprayer after each use. After using
water-based products, rinse thoroughly with soapy water
then clean water, being sure to flush out the hose and flow
control. After spraying solvent or oil-based products, follow the
chemical manufacturers’ recommended cleaning procedure,
following up with a thorough rinsing and flushing of the sprayer,
hose and flow control with soapy water then clean water.
WARNING! Do not store chemicals in the tank. If the chemical
is stored in the tank, it can clog the system as it dries and
destroy the seals and other components.
STORAGE
1. Remove the complete hose assembly (hose w/siphon
tube, wand, flow control) from the tank.
2. For proper drainage and drying, lock flow control lever
on.
3. Loosen pump assembly, but leave in the tank.
4. Store all components in a clean, dry area.
WARNING! Store the sprayer in a safety place out of
Children’s reach.
PUMP MAINTENANCE & DISASSEMBLY
To keep the pump working smoothly and efficiently, the plunger
o-ring needs to be lubricated often by applying grease or
petroleum jelly around the outside of the plunger o-ring.
1. Remove pump assembly from the tank.
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. Pull up and the handle and the
plunger assembly should come out of the pump cylinder.
• To reassemble, insert the plunger assembly into the
cylinder and snap the cap back into place.
