OPERATION AND SERVICE INSTRUCTIONS

GALVANIZED & STAINLESS STEEL SPRAYERS

MODELS: 111, 112, 147

WARNING!!! THIS PRODUCT IS DESIGNED TO SPRAY CHEMICALS THAT MAY BE HARMFUL AND COULD CAUSE
SERIOUS PERSONAL INJURY IF INHALED OR BROUGHT INTO CONTACT WITH THE USER. FAILURE TO READ
AND FOLLOW OPERATING INSTRUCTIONS BEFORE USE AND/OR MISUSE OF THIS PRODUCT COULD RESULT
IN EXPLOSIVE FAILURE WITH MAJOR INJURIES.

• ALWAYS water test unit before using.

•ALWAYS wear protective clothing, eye protection, and gloves.

• ALWAYS READ AND FOLLOW label instructions for chemicals to be applied.

• AFTER USE - release pressure, empty, and clean the sprayer.

• RELEASE pressure in sprayer before servicing.

• DO NOT alter sprayer.

• DO NOT spray gasoline or other flammables.

• DO NOT store liquids in tank.

• DO NOT leave sprayer in the sun.

! OPERATING INSTRUCTIONS:

1.Remove the pump from the tank by turning counter clockwise.

2.Prepare spray solution following instructions provided with the chemicals. For best results, mix in a separate container and
strain through cloth sieve when pouring into tank. Do not fill tank above the maximum fill marker.

3.Close tank by inserting pump assembly through opening. Turn clockwise until pump is sealed tightly into tank.

4.When the sprayer is filled, 20-30 strokes on the pump should supply enough pressure for spraying. More strokes will be
needed if tank is only partially filled. As the fluid level goes down, more strokes may be needed. To work the pump, unlock
pump handle from pump cap by turning counter clockwise. Lock the handle again by turning clockwise.

5.To start spraying, squeeze the flow control lever. Release pressure
from the lever and the spraywill stop. To spray continuously, squeeze
the lever, and slide the lock forward. See Figure.

6.If your sprayer has an adjustable cone nozzle, screw it in clockwise for a fine mist, and counter clockwise for a coarse
stream. Flat fan nozzles are not adjustable.

7.To depressurize the tank, turn the tank upside down. Squeeze the flow control lever until all air pressure is gone.

WARNING!!! To prevent ejected pump assembly and/or solution from striking and injuring you, never stand with face or

body over the top of the tank when pumping or loosening pump.

8.Empty any remaining solution into a proper storage container or disposal container. Do not store chemicals in the tank. If
the chemical is stored in the tank, it can clog the system as it dries and can promote corrosion.

9.Clean the sprayer after each use to prolong its life. After using water-based products, rinse thoroughly with water, being
sure to flush out hose and flow control. After spraying solvent or oil-based products, follow chemical manufacturer’s
recommended cleaning procedure.

10.To store the sprayer, hang the tank upside down with the pump removed and the flow control locked “on”. This allows for
proper drainage and drying.

11.Check for worn or damaged parts frequently.

! MAINTENANCE AND DISASSEMBLY: To keep the pump working smoothly and

efficiently, the plunger u-cup seal needs to be lubricated often. Disassemble pump and apply grease
or petroleum jelly around the outside of the plunger cup. To disassemble the pump, push cam plate
upward with two thumbs, as shown, then remove the plunger assembly from cylinder. To reassemble,
replace pluger assembly into cylinder and press camplate back into cylinder. Note: Your sprayer was
lubricated at the time of manufacture.

! TROUBLESHOOTING: Always depressurize the sprayer, remove chemical solution, and clean the sprayer before making

repairs. Refer to the parts diagram for part numbers and names. Replacement parts may be purchased at most RL
