Hydraulic Connection

causym CAUTION: Pressurized hydraulic liquids may penetrate the skin and cause serious injury. Release the pressure before disconnecting any hydraulic or other hoses. Tighten all connections before allowing the pressure to build up. Keep hands and body away from openings and nozzles which eject pressurized liquids. When looking for any leakage, do not use your hands, but a piece of paper or cardboard.

ANY liquid penetrating the skin must be removed surgically within a couple of hours to prevent inflammation.

Connection on Machines with Hydraulic Operation by Tractor Selective Control Valves
  • Connect hydraulics for height adjustment (A).
  • Connect hydraulics for spray boom folding/unfolding (B).
  • Connect hydraulics for controlling spray boom tilt (C).

The hydraulic hoses have been provided with coloured protective caps. The protective cap colours have the following meaning:

  • red = double-acting selective control valve pressure connection, spray boom folding/unfolding
  • blue = double-acting selective control valve return connection, spray boom folding/unfolding
  • black = single-acting selective control valve connection, spray boom height adjustment
  • yellow = double-acting selective control valve pressure connection, spray boom tilt
  • green = double-acting selective control valve return connection, spray boom tilt
