SET-UP AND OPERATION
BEFORE STARTING WORK please read the following application and set-up instructions
to ensure safe and productive operation.
HYDRAULICS (TRACTOR OIL FLOW REQUIREMENTS)
For the Spreader to operate at its maximum rates, a tractor hydraulic flow of approximately 90 Litres per minute
is required. Standard SAM Computer Controlled Spreaders are fitted with two OMP50 hydraulic motors running
in series, requiring an external oil flow of a max of 50 litres/minute. The floor drive requires approximately 40
Litres to rotate at its maximum speed.
It is very important that you adjust the hydraulic oil flow from the tractor as above. Note, the higher the
bypass oil flow, the higher the pressure in the e-Spreader's hydraulic system.
COUPLING THE HYDRAULICS
The live hose (red) must be coupled to a high pressure outlet point on the tractor's external hydraulic system.
This take off point can be fitted to an existing double acting valve already fitted for farm machinery, or a new
fitting can be installed.
The return hose (yellow) can be coupled into the same double acting bank or a free flow dump return using the
quick release coupling supplied.
HYDRAULIC OPERATION
The hydraulic spinners and valve control must be coupled to the tractors hydraulic system to ensure safe
operation. If you are unsure of set up please contact your local dealership or Coombridge & Alexander directly.
Always ensure tractor oils are kept in excellent condition. Beware when changing an Spreader
between different tractors. Pump oil out of the hoses unless they use the same hydraulic oil.
SPREADING CENTRES
We recommend spreading at 15 metre centres for granulated fertiliser products and 10 metre centres for powered or
fine granulated products such as Lime. You can choose any spread width in the set-up mode.
MESH SCREEN
We recommend removing the mesh screen from inside the polyethelene bin when spreading lime.
