6. Maintenance & Storage Program
In general Sumo advise that you should visually check over the machine before each
operation and transport to ensure there are no visible defects, loose parts or risk to either
the operator or the public. Maintaining a thorough regimented maintenance schedule will
help to prolong the life of your machine.
Wherever possible stand on flat platforms and NEVER on rotating, breakable, or adjustable
elements such as the packer, points, disc etc. Avoid all cables and hoses. Be mindful of your
footing and an environmental element that may cause additional movement. As the
machines are mostly painted surfaces, they can be slippery. All wings and foldable
elements must be full folded out before approaching the machine. NEVER stand on a
folded machine, or under its foldable features. NEVER stand on the machine when it is
connected to an active tractor. Follow all advised parking guidance given within this
manual.
Wheel studs on trailed machines should be checked for tightness after the first 10 hours
of operation and then again at regular weekly intervals. Tyre pressures should also be
checked at regular intervals, more so during continued use. For torque values and tyre
pressures, see the relative Machine Manual & Parts Book.
Some Sumo parts are considered to be wearable due to the nature of their design and use.
For best results, check routinely and replace as required. This will help prevent
loss/destruction of implements during work.
Check and re-tighten all fasteners every 24 hours. Tighten to standard ISO values, unless
otherwise stated. If removed, all Nylock and/or Aero-tight nuts must be replaced, otherwise
they lose their effectiveness.
6.1 Hopper Emptying
The hopper can be completely emptied of any product by the following steps. First,
close the Orga metering slide, to shut off the tank. Second, remove the Orga insert and
nylon sleeve to allow any product in the metering unit to drain out. It is advisable to
have a bag or bucket to catch any draining product. Thirdly, the slide should be opened
to allow product from within the tank drain out. This is the quickest and easiest
method of draining the tank. It is important to replace the nylon sleeve and Orga insert
tube after the product has been drained. It is a good time to check the integrity of the
neoprene gaskets on the inside of the flanges to ensure that will continue to create an
airtight seal. Failure to replace the nylon sleeve and Orga insert tube before new
product is added to the hopper will result in product draining out the bottom of
hopper.
6.2 Coulter Maintenance/Checking
The condition of each coulter assembly should be regularly monitored weekly. In
particular all pivot points should be observed to ensure the grease-free polymer
bushes remain tight. Any debris should be cleared from pivot points and bearings.
