MAINTENANCE
Since the sprayer needs little maintenance, if you follow the steps mentioned in this manual its lifespan will be very long. Do not keep the sprayer with
pressure after finishing your spraying job, release the pressure through the nozzle depressing the trigger, then take the cap and strainer out and pour the
remaining solution. Now rinse system with fresh water as follows:
Allow pressure to escape. Remove cap and pour out remaining solution, then rinse all parts thoroughly with clean water.
Put approximately ½ gallon of fresh water in the tank, pressurize and flush the pumping system by depressing trigger at least 2 minutes, then drain all remaining
water.
Carrying straps will not absorb chemicals. In the event of a formula spill, however, tank and straps should be properly cleaned with water to eliminate all possible
risk of skin irritation.
A unit that has been used with herbicides should never be used to spray insecticides, unless the sprayer has been properly cleaned and all the chemicals
neutralized. Failure to do this could cause you to kill plants that have been sprayed. Consult the manufacturer of the chemicals in use to obtain proper instructions.
Always store tank clean and empty in a dry, shaded location.
To keep your sprayer in "optimal" conditions of use is necessary to maintain oiled
NOTE:
"Always" the following parts: The o-rings gun, piston ring, breathing valve cover gasket,
5.1 MAINTENANCE GUIDE
Rinse with clean water externally and internally, to avoid risk of contamination. To keep your sprayer in good condition it is recommended to change the following
parts when servicing your sprayer:
- Checks for O-rings and cylinder
Disassembly instructions:
1.- Place the sprayer upright on a flat surface. Pull the "R" pin from the upper end of the pump lever. Watch those washers.
2.- Loosen the pump holder nut atop the tank. Pull out pump tube. To check the ball valve, remove piston fitting and make sure the ball is clean
and in good shape, if not replace it.
3.- To replace the piston sleeve loose the piston fitting taking care not to lose the check ball; once the piston sleeve has been replaced, tighten
the ball holder nut. Besure the check ball has been set in place. Do not forget to oil it.

PROBLEM
The tank collapses when pressuring it.
The piston sleeve does not run smoothly
and it is hard to pump.

ATTENTION
OIL PUMP TUBE AND
PISTON SLEEVE
IN THE SPRAYER
The breather check needs lubrication.
The piston sleeve is stuck.
The piston sleeve is worn out or shrunk.
The ball valve is stuck or dirt is preventing the
ball valve to sit properly on the ball-holder nut.
The plunger o-rings are worn out
or swollen.
The pump tube and pump holder
nut need lubrication.
Filter or nozzle are blocked.
- O-ring for pressure chamber
To lubricate all parts; Use
silicone-based grease.
CAUSE

- Pump tube gasket and guide check.
- Pump tube o-ring and guide check
NOTE:
SOLUTION
Lubricate or replace if damaged.
Replace the piston sleeve and lubricate.
Replace the piston sleeve and lubricate.
Clean the ball holder nut, and the ball
valve, replace them if necessary.
Lubricate both of them.
