MAINTENANCE
5.
The compression sprayer requires minimum maintenance. Follow in detail the steps mentioned in this manual and the useful life of the equipment will
be very long. At the end of your spraying job, don't leave the applicator with pressure, let all the pressure release through the nozzle, or unscrew the
pump handle and turn over the sprayer to empty the remaining solution in an appropriate container for it. Now rinse the sprayer system with fresh water,
as follows:
Pour approximately 1/2 gallon of fresh water in the tank, pressurize and flush, the pumping system by pressing trigger at least 2 minutes, then
drain all remaining water.
A unit that has been used with herbicides should never be used to spray insecticides, unless the sprayer has been properly cleaned and all
other chemicals neutralized. Failure to do this could cause you to kill plants that have been sprayed.
Always follow manufacturer's instructions of the chemicals in use to avoid accidents and take maximum advantage of the product.
Store your sprayer clean, empty and dry in a place protected from sunlight.

MAINTENANCE GUIDE
To keep your sprayer in optimal condition, keep the following parts always greased: shut-off O rings, Piston sleeve, Pump tube O rings,
NOTE:
Plunger O rings, Nozzle O ring.
Wash the sprayer inside and outside with fresh water, to be able to handle it without contamination risk. It is recommended to replace all wear parts when perfor-
ming a repair job:
- Piston sleeve
Instructions for compression sprayers:
1.- Change the wear parts in the pump tube, shut-off, spray lance and nozzle if your sprayer is leaking or as preventive maintenance.
2.- Unscrew the nut between spray lance and shut-off.
3.- Change oring located between nut and shut-off.
4.- The shut-off is comprised by several pieces, remove the lower plug, remove plunger and replace the two o-rings. Lubricate before assembly.
5.- Remove the pump tube from the tank and replace O ring located in the upper part, lubricate before assembling.

To lubricate all parts; Use
silicone-based grease.
SOLUTION
Check the piston sleeve. If it is worn-down repla-
ce it and grease it, if not just grease the edges.
Check the antenna and if necessary replace
the seal. Lubricate before reassembling.
Replace and grease the new O rings and
plunger
Loosen the hose clamp and check if the hose
or the tank outlet are clogged and if so,
proceed to unclog them with pressurized air
or water
Tighten the tube and grease the O ring.
