Lubrication and Maintenance
Start-up Inspection
During the first few days of operation, before
starting each day check that all hardware is tight,
in particular the wheel bolts. Inspect for any leaks
whilst running and tighten all hose clamps.
PTO SHAFT LUBRICATION POINTS
PTO Shaft
Grease the PTO shaft with multi-purpose grease at
the locations shown before starting for the first time
and then at the intervals shown. This is the amount
of lubrication recommended for normal operation.
More frequent inspection and lubrication may be
needed under very dusty conditions.
Diaphragm Pump (PTO Model only)
Check the oil level in the viewer daily and if
necessary top up with SAE 20-40 multigrade
engine oil.
Filters
Clean all filters daily or as stated below. More
frequent cleaning may be found necessary
depending upon circumstances.
Check and, if necessary, clean the basket strainer
under the tank lid before each top fill.
Check and, if necessary, clean the bottom fill filter
before each bottom fill. Unscrew the plastic ring to
remove the element. The sprayer should be
stopped with the fill valve closed (mid position).
Always clean the suction filter after each tank of
chemicals is emptied. Close the internal shut-off
valve before removing the element by turning the
yellow cap to the “Unlock” position. This prevents
liquid draining from the tank when the element is
removed. Unscrew the black plastic ring to remove
the element. After replacing the element, reopen
the shut-off valve by turning the yellow cap to the
“Lock” position.
The bottom fill and suction filters are both located
on the sprayer control panel. The sprayer should
be stopped before removing these filters.
Purge the high pressure filter daily. It is located
beneath the control panel and can be purged of
accumulated foreign material by opening the tap
with the black knob on its base whilst the sprayer
is running.
Also remove the bowl of the high pressure filter
regularly to inspect and, if necessary, clean the
element. Stop the sprayer before removing the
bowl.
The best method for cleaning filters is to wash
them with a soft bristle brush. Check for any tears
or holes and replace if damaged. Take care that
the sealing ‘O’ ring is refitted.
Tank and Spray Lines
At the end of each day run clean water through the
pump and lines to purge them of chemicals. Rinse
out the tank to remove powdered material.
Never leave chemicals in the tank that may settle
to the bottom, harden and break into lumps as this
may block the suction filter. Refer to the Operating
section for information on draining the tank and
flushing the system.
Tyres
Inspect the tyres regularly and keep inflated to the
correct pressure. For 11.2 x 44 radial tyres the
pressure is 45psi.
Foam Marker (Optional Equipment)
Foam Lines
For efficient performance it is important to remove
unused foam and foam solution from the system
after each day’s use.
Fully close the concentrate needle valve and fully
open the water needle valve then run the marker
system for several minutes until clean water runs
from the dropper at each end of the boom. Operate
the solenoid valve several times during this
process to flush the fluid line to each end of the
boom.
Foam Marker Air Compressor Filter
The filter on the compressor box should be
checked each day and cleaned if necessary.
Unscrew the filter cap and remove the paper
element to check its condition.
To clean the element blow the dust out using
compressed air but do not exceed 50 psi air
pressure. Replace the filter if it is damaged or
unable to be cleaned satisfactorily.
Reinstall the element in its holder and refit the cap
securely.
