Once a week check, clean, and replace (if needed) the following filters. Be sure to follow the Flush, page 44, prior to performing filter maintenance.

• Both pump filters; see your pump manual for instructions.

• Main air inlet manifold filter; see your sprayer repair manual, Replace Air Filter Element section, for instructions.

• Air regulator filter (5 micron) on air control assembly; see your sprayer repair manual, Replace Air Filter Element section, for instructions.

• B side mix manifold strainer; see your mix manifold manual.

Once a week, check and tighten throat seals on both pumps and dosing valves. Be sure to follow Flush Mixed Manifold, Hose, and Spray Gun, page 44, priorto tightening seals.

Adjust the packing nut weekly so it is just tight enough to prevent leakage. Use a spanner wrench or a 0.25 in. (6.3 mm) diameter rod to tighten the nut. Do not over-tighten.;

Ensure that all pumps are shut off and close the Y-strainer valve (ES)

Place a container under the strainer base to catch drain off when removing the strainer plug

Remove the screen from the strainer manifold. Thoroughly flush the mesh screen (MS) with compatible solvent and shake it dry

Inspect the screen. No more than 25% of the mesh should be restricted. If more than 25% of the mesh is blocked, replace the screen. Inspect the gasket and replace as needed

Ensure that the pipe plug (PP) is screwed into the strainer plug (SP). Install the strainer plug (SP) with the mesh screen (MS) and gasket (SG) in place and tighten. Do not over tighten the strainer plug--let the gasket make the seal

Open the Y-strainer valve (ES). Ensure that there are no leaks and wipe the equipment clean

Is the air motor properly lubricated?

Change the gear reducer oil every 2500 hours, or six months (whichever comes first) of operation under normal conditions. More frequent oil changes are needed under severe operating conditions or in atmospheres containing excessive moisture or abrasives. See your agitator manual for the oil changing procedure.
