Lubrication and Maintenance
Start Up Inspection
During the first few days of operation, before
starting each day check that all hardware is tight
including all hose clamps. Inspect the unit for
leaks while operating.
PTO Shaft to Tractor
Grease the PTO shaft 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.
If a wide-angle PTO shaft is fitted, ensure that all
three universal joints are greased, as shown in
the diagram below. All other grease points on the
shaft and the lubrication intervals are the same as
a standard PTO.
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-50 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. Close the shut off valve before
removing the element by pushing the yellow tap
in and turning it counter-clockwise, then unscrew
the filter cover to remove the element, refer to the
Supaflo suction filter diagram in Operation
section.
For 1000L sprayers move the Main Valve to a
horizontal position to close flow from the tank
before opening the filter for element cleaning.
After cleaning return the Main Valve to the vertical
position to allow flow from the tank to the filter and
pump.
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.
