Nozzle tubes and fittings
Poor seals are usually caused by;
. missing O-rings or gaskets
. damaged or incorrectly seated O-rings
. dry or deformed O-rings or gaskets
. foreign bodies
Therefore, in case of leaks: DO NOT over-
tighten. Disassemble, check condition and
position of O-ring or gasket, clean lubricate and
reassemble.
For radial connections only hand tighten them.
The O-ring to be lubricated ALL THE WAY ROUND before fitting on to
the nozzle tube.
For axial connections, a little
mechanical leverage may be
used.
Off-season storage
When the spraying season is over you should devote some extra time
to the sprayer before it is put away for the winter.
Hoses
Check that none of the hoses are caught or have sharp bends.
A leaky hose can give an annoying delay in the middle of the spraying
job. Therefore check all the hoses and change if there is any doubt
about the durability.
