Lubrication and Maintenance
Start Up Inspection
During the first few days of operation, before
starting each day check that all hardware is tight
and tighten all hose clamps. Inspect the unit for
leaks while operating.
PTO Shaft to Tractor
Grease the PTO shaft, including all three
universal joints, with multi-purpose grease at the
time intervals shown below. This is the amount of
lubrication recommended for normal operation.
More frequent inspection and lubrication may be
needed under very dusty conditions.
Every 20 hours slide the PTO shaft apart, clean
the telescopic tubes with kerosene and apply
multi-purpose grease to the sliding surfaces, then
reassemble. This is most important in dusty
conditions.
Internal PTO Shaft
Grease the universal joints on the internal PTO
shaft, which is connected between the rear of the
pump and the fan drive at the rear of the sprayer,
with multi-purpose grease every 500 hours, or
during the annual inspection.
The telescoping sections of this internal shaft do
not require regular greasing as the shaft length is
constant and the sections do not slide in
operation. Check that the shaft is free to slide
during the annual general inspection.
Pump
Check the oil level in the viewer daily and if
necessary top up with SAE 20W-40 multigrade
engine oil. The oil must reach the mark on the side
of the oil level viewer.
Gearbox
Check the oil level every 50 hours and if required
top up with SAE 85W-140 gear oil. The level
should be halfway up the viewer on the side of the
gearbox.
Filters
Clean all filters regularly. The best method is to
wash them with a soft bristle brush. Check for any
tears or holes and replace if damaged. Check and
if necessary clean the tank lid basket strainer
before each fill.
Always remove and clean the element of the
suction filter before each tank refill and at the end
of the day. Ensure the O-ring is in good condition
when refitting. On Supaflo models close the shut
off valve before removing the element by pushing
the yellow tap in and turning it counterclockwise,
then unscrew the filter cover to remove the
element, refer to the Supaflo suction filter diagram
in Operation section.
Flush the pressure line filter daily by opening the
red tap at the end of the filter housing and running
the pump for a few minutes to purge any foreign
material from the element, refer to the diagram of
the appropriate valve arrangement in the
Operation section.
Tank, Pump and Spray Lines
At the end of each day run clean water through
the pump, spray lines and nozzles to purge them
of chemicals. Rinse out the tank to remove any
powdered material.
In the case of frost or freezing conditions run the
pump dry to prevent water freezing in it or the
spray lines and damaging components.
