Maintenance
In order to derive full benefit from the sprayer for many years the
following few but important rules should be kept:
Cleaning the sprayer
- see Spray Technique book.
Filters
Clean filters ensure :
•
Sprayer components such
as valves, diaphragms
and operating unit are not
hindered or damaged
during operation.
•
Nozzle blockages do not
occur whilst spraying.
•
Long life of pump. A
blocked suction filter will
result in pump cavitation.
The main filter protecting
sprayer components is the
suction filter at the top of the
tank. Check it regularly.
Ensure the O-ring on filter housing is in good condition and lubricated.
The operating unit has an in-built pressure filter. See section on Drain
valve operation.
Lubrication
Recommended lubrication is shown in following tables. Use ball
bearing grease (lithium grease No.2)
NOTE: If the sprayers are cleaned with a high pressure cleaner or it
has been used to spray fertilizer, we recommend lubrication of the
entire machine.
