2.
Once a week check the state of the hydraulic hoses, especially sections in contact with
the equipment.
3.
Once a week, control that there are no leaks from the hydraulic connectors.
4.
Retighten the hydraulic connectors if required after the first few hours of operation.
6- HYDRAULIC SAFETY VALVE
1.
All distributors are equipped with a general hydraulic safety valve set at
180 bars
and
located at the pressure inlet of the distributor unit.
2.
With the motorized regulator n°
824 404,
the hydraulic safety valve fitted in the
regulator is set at
180 bars.
3.
To check the valve calibration, connect a pressure gauge in parallel on the pressure line:
a) With hydraulic door:
- activate the dual-acting cylinders to limit,
- read the set pressure.
b) With moving floor hydraulic motor:
- block the return port of the forward running motor,
- activate the distributor component of the forward running moving floor,
- read the set pressure.
4.
To calibrate or decalibrate, screw or unscrew the valve’s adjusting screw, and control
with pressure gauge.
7- SAFETY VALVE OF HYDRAULIC DOOR
1.
Valve N°
825 246
fitted on the lower port, piston side, of one of the hydraulic door
cylinders.
2.
Safety for any interventions on or inside the spreader (see safety instructions).
3.
Should be completely open when operating and completely closed for interventions on
or inside the spreader (see sticker page 13).
4.
Check at least once a week the mechanical functioning of the valve by operating the
lever
2 to 3 times
without using the hydraulic distributor functions.
8-TAIL LIGHTS FOR ROAD SIGNALLING
1.
An articulated case on each light, activated by an electric cylinder (electrically protected
by an internal resettable thermal fuse) is controlled with the last button at the top of the
electric control unit.
2.
Each case hides and protects the light whilst spreading. The lights can be completely
uncovered for driving on the road.
3.
Before driving on the road, check that both lights are clean and fully visible. Also check
the mechanisms and lights to make sure that they are working properly.
