5.8 Fitting and connecting the hydraulic metering slide

controls

Injury hazard through crushing from remote control elements

The remote control elements (positioning lever, metering slides) can cause
crushing and amputation injuries.

•

When activating control levers i.e. metering slides, ensure that no one is in

the vicinity of any moving parts.

Injury hazard due to defective or incorrectly sealed hydraulic hoses

Hydraulic fluid escaping under high pressure can penetrate the skin and cause
serious injuries.

•

Regularly check all hoses at least every six months and before each season

commences, for mechanical defects e.g. cuts, abrasions, crushed sections,
kinks, tears, leaks, porosity, etc. Replace any suspect hoses immediately
before operating the machine.

•

Even when carefully stored and correctly used, hoses and hose connecti-

ons undergo a natural aging. Therefore, their stocking and operational pe-
riods should not be exceeded.

•

The useful life of an undamaged hose should be limited to six years, inclu-

ding a possible maximum two-year stocking period.

•

The hydraulic hose manufacturing date is indicated on the hose with the

month and year of manufacture (e.g. SLP 8/00).

•

Use suitable protection when locating leaks (safety goggles, gloves, etc.) in

order to avoid injury.

•

In case of injury, immediately consult a doctor, as there is a risk of serious

infection!

Storing hydraulic hoses when fertiliser spreader is uncoupled from the
tractor

Hydraulic hoses can be laid between the upper link point and the hopper.

5.8.1 Single acting hydraulic metering control for MDS 55 K /

65 K / 85 K / 735 K / 935 K

The MDS 55 K / 65 K / 85 K / 735 K / 935 K metering slides operate with two
hydraulic cylinders fitted complete with exterior mounted return springs.

Oil pressure closes - Spring tension opens

Connecting the hydraulic metering slide control:

The following hydraulic valves are needed on the tractor:

•

Two single acting valves, or

•

Two double acting valves with free return, or
one single and one double acting valve with free return
