Installing the Pump Lever Shaft(Models HD400, CD400, CD550 only)

1. Fit the pump levershaft into thelower rightorifice on thesprayer base(chamber sideof sprayer).

2. Use a rubbermallet to strikethe shaftsmoothly until the hole on the shaft end aligns with theopening on the base reinforcement.

3. Lock the shaft in place with cotter pin.

Installing the Lance Holders

Installing the Pump Lever1. Lightly grease the end of the pump lever connecting rod,

and insert into the upper hole in the pump lever. Securewith flat washer and cotter pin.

2. Install a flat washer on the opposite end of the connectingrod. Lightly grease the rod end and insert it into the holeon the top of the pump chamber. Secure with flat washerand cotter pin.

3. Install a flat washer on the pump lever shaft.

4. Lightly grease the hole on the end of the pump lever and

assemble to the pump lever shaft. Secure with flat washerand cotter pin.

3. Push the hosethrough the screwcap and lock into thetrigger valve.

4. Assemble the screw cap back onto the trigger valve.

CAUTION!Do not overtighten the screw cap!

Adjusting the Shoulder StrapsTightening1. Hook the shoulder

strap ends to the sideof the sprayer base.

2. Put the sprayer on yourback.

3. Hold the adjuster ringfirmly and pull untilbackpack is secure in place.

LooseningLift up on the adjuster to release tension.

Pressure Test the Sprayer1. Once assembled, fill the sprayer with water.

2. Pump the lever approximately 15 times.

3. Inspect the tank, hose, lance, and trigger valve forleakage.

NOTE : Retightening the appropriate connections andfittings can stop most leaks. Any leakage must be repairedprior to putting the sprayer in service.

MaintenanceCleaning the sprayer

After each use, wash andrinse all equipment withwater in an approveddecontamination area.

Remove all chemi-cals before storingthe sprayer for anextendedperiod!Chemicalproductshave differentreactions and cancause damage to thesprayer componentsand environment aswell as personal injury.Refer to the SafetyPrecautions on page 4.

Periodically clean thechamber and lubricatecomponents as shown.Remove the chamberto lubricate theplunger.

Cylinder Maintenance, CD400 and CD550Disassembly1. Remove the pump-lever connecting

rod from the pump chamber,loosen the packing ring nut thatsecures the chamber to the tank,then remove the chamber from thecylinder.

2. Remove the nuts from the cylinder,then remove the cylinder.

3. Loosen the bolts, remove thespring, ball seat and ball.

4. To ease assembly and help preventwear, lightly lubricate the plunger with lithium-basegrease, then insert the pump chamber into the cylinder.

5. Reconnect the pump-lever connecting rod and retightenthe packing ring nut.

Cylinder Maintenance, HD400Disassembly1. Remove the pump-lever connecting

rod from the pump chamber.

2. Loosen the nut that securesthe chamber to the tank,then push the chamber intothe cylinder all the way.

3. Turn the chamber counter-clockwise until the cylinderis free, then pull it out of thetank.

BandWidth

Determining Coverage1. Hold the

lance at theworking heightand spray a testpattern to measure theapplication band width.

2. Based on the bandwidth, calculate thetotal walking distancerequired to spray thedesired area. Use to thechart below.

Calibrating the Sprayer

Measuring Flow Rate(requires optional calibration bottle, P/N 834309)

1. Attach the calibrationbottle to the lance.

a. Remove the nozzle, capand filter.

b. Mount the calibrationcover to the spray lance.

c. Reinstall the nozzle,filter and cap.

d. Screw the calibrationbottle onto the cover.

2. Using the calibrationbottle:

a. Hold the lance at yournormal working positionand spray into the bottle while walking the distancerequired to spray an area corresponding to 25m 2.

b. Place the bottle on a level surface and observe theliquid level visible through the side of the bottle. Matchthe liquid level to the corresponding scale on the calibra-tion bottle.

c. Empty the bottle and repeat Steps a and b to determinethe average of two or more readings.
