Tasks
NOTE:
Empty the spray tank by disposing of
any residual spray in the appropriate manner.
Refill the tank with approximately 10% of
the tank volume of fresh water to flush the
pump and boom. The following steps should
be adhered to: Unfold the boom in an area
convenient to dispose of residual chemical
(an area where chemical can not run-off into
above ground or sub surface water courses).
• Operate the diaphragm pump at idle revs
• Open the Boom Supply Ball Valves, and
allow to rinse for a sufficient amount of
time.
• Close the Boom Supply Ball Valves, and
open the Hose Reel Ball Valve to rinse
hand gun line (where fitted).
• Run sprayer until fresh water contents has
been flushed through the system.
• When the tank has been emptied, shut off
the pump drive by either disengaging the
PTO, or closing the hydraulic supply.
• To clean and decontaminate the sprayer,
follow the instructions provided on
the chemical label for appropriate
decontamination procedure.
• Clean all filters.
• Clean all nozzles.
CAUTION:
If the sprayer is left attached to the
tractor when parking the sprayer, make sure
the tractor park brake is applied, the engine
turned off and the sprayer lowered onto the
ground. If the sprayer is to be disconnected
from the tractor: Ensure the main tank and any
other tanks fitted are empty.
• Lower the sprayer to release the weight
off the linkage arms (the sprayer may need
lowering onto a pallet or several large
pieces of timber).
• Adjust the top linkage arm until it becomes
loose, then remove from sprayer.
• Loosen the stabilising chains on the
linkage arms, then detach arms from the
sprayer.
• Disconnect all lines between the sprayer
and the tractor (i.e. hydraulic lines, foam
marker lines, etc.)
• Remove the PTO shaft from both the
sprayer and the tractor.
NOTE:
Store the sprayer in a suitable location
to prevent freezing. If the sprayer is to be left
where freezing may occur, cover the pump
and flow meter with a material bag and empty
pump and flow meter of all water (run the
pump dry for 15-20 seconds). Make sure any
ice has thawed before using sprayer.
End of Season Tasks
If the sprayer is to be stored for a long period
of time without use, there are several tasks
that need to be performed. Clean the sprayer
thoroughly as described under
• With the sprayer attached to the tractor,
carry out a thorough observation to
determine if there is any damage to the
sprayer.
• Park the sprayer in a position where it will
not be affected by frosts, and preferably
out of direct sunlight.
• Ensure all tanks are empty.
• Lower the sprayer to release the weight
off the linkage arms (the sprayer may need
lowering onto a pallet or several large
pieces of timber).
• Adjust the top linkage arm until it becomes
loose, then remove from sprayer.
• Loosen the stabilising chains on the
linkage arms, then detach arms from the
sprayer.
• Disconnect all lines between the sprayer
and the tractor (i.e. hydraulic lines, foam
marker lines, etc.).
• Remove the PTO shaft from both the
sprayer and the tractor.
• Periodically check the sprayer to ensure
frosts and/or vermin are not damaging the
machine.
