MODELS: 2601, 2602, 2602HD, 2603, 2603HD, 2501, 2502, 2503,

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 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.

If your sprayer is equipped with our new poly flow control, please assemble according to the following instructions:

1. Be sure to first insert pink siphon tube into hose insert otherwise sprayer will not operate.

2. Lubricate (with grease or petroleum jelly), the o-ring on the hose insert and slide into tank until fully seated.

3. Slide tank nut to threaded connection and securely screw onto tank.

4. Attach the flow control to the hose by unscrewing the flow control nut from the back of the flow control. Slide it directly onto
the end of the hose.

5. Push the hose onto the back of the flow control all the way past the barb and up to the threads and screw together. Hand
tighten only.

6. Push the extension rod into the flow control until it stops. Slide extension nut and o-ring to the flow control and screw
together. Hand tighten only.

! OPERATING INSTRUCTIONS:

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

2.Read label and all instructions for chemicals to be applied.

and pour enough chemical into the sprayer to yield the amount of spray solution desired.

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

RL Flo-Master Quick Connect fitting to your garden hose.

4.Turn the water “on”. Water will not flow through the Quick Connect fitting until it is pushed onto the special red tank adapter.

Make sure the flow control is in the “off” position and the pump is screwed in tightly.

5.Push the Quick Connect fitting onto the red tank adapter until it snaps into place. Water will now flow into the tank, com

pressing the air trapped inside.

6.When water reaches the desired level in the tank - CAREFUL NOT TO EXCEED MAXIMUM FILL LINE - remove the

Quick Connect by pulling back on the gray collar. Once the hose is removed, you are ready to spray. See note in Trouble

Determine the proper ratio of concentrated chemicals to water

shooting Section.NOTE: If you re-pressurize using a water system, you will need to add more chemicals to maintain desired
solution concentration.

7.If a pressurized water system is not available, use the auxiliary pump. When the sprayer is filled, about 20 strokes on the

pump should supply enough pressure for spraying. Pumping may 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 clock
wise, lock handle again by turning clockwise.

8.To start spraying, squeeze the spray control lever. Release pressure from the lever and the spray will stop.

9.If your sprayer has the poly flow control, lock “on” for continuous

spraying by squeezing the lever and sliding the lever forward.
If your sprayer has the brass control,lock it “on” by squeezing
the lever and pull the lock lever back.

10.To depressurize the tank, turn the tank upside down. Depress the spray control lever until all the 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.

11.Empty any remaining solution into a proper storage 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 it can promote corrosion.

12.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 manufacturers’ recommended
cleaning procedures.

13.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.

14.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,
according to the instructions below for your model,and apply grease or petroleum jelly around the outside of the plunger cup.
Note: Your sprayer was lubricated at the time of manufacture.

STRAIGHT NECK SPRAYER MODELS 2501, 2502, 2503:

Place the pump assembly on the edge of the table as shown and
pull with downward motion. The assembly will snap apart when
the tank cap strikes the table. To reassemble, insert the plunger
assembly into the pump cylinder, resting the tank cap on top of
the pump cylinder. Turn the assembly upside down and tap firmly
on a hard surface to snap pump assembly back into place.

FUNNEL TOP SPRAYER MODELS 2601, 2602, 2602I, 2603, 1602:

tabs on each side of the pump and pry down. Pull up on the handle
and the plunger assembly should come out of the pump cylinder.
To reassemble, insert plunger assembly into cylinder and push
the tabs back into place.

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