PROBLEM

CAUSE SOLUTION
The breather check needs lubrication. Lubricate or replace it if it is damaged.
The piston sleeve does not run smoothly
and it is hard to pump.
The agrichemical used has made the
piston sleeve to swell up.
Replace the piston sleeve, lubricate it first.
The piston sleeve runs too smoothly and
it does not keep pressure.
The piston sleeve is worn out or shrunk. Replace the piston sleeve, lubricate it first.
Although the sprayer is being pumped
vigorously it does not build pressure.
The plasticball is stuck or dirt is preventing
the ball to sit properly on the ball-holder nut.
Clean the ball holder nut, and the ball,
replace them if necessary.
When pumping a creak is produced between
the pump tube and pump holder nut.
The pump tube and pump holder nut
need lubrication.
Lubricate both of them.
The shut-off valve does not close after
releasing the trigger.
The plunger O-rings are worn out or
swollen.
Replace them and lubricate the plunger
with the new O-rings.
The shut-off valve does not function
when depressing the trigger.
