Preparing the Machine

  1. Park the machine on a level surface.
  2. Disengage the PTO (if equipped) and lower the cutting units.
  3. Engage the parking brake.
  4. Shut off the engine and remove the key.
  5. Wait for all movement to stop and allow the machine to cool.
    Warning
    Hot hydraulic fluid can cause severe burns.
    Allow the hydraulic fluid to cool before performing any maintenance to the hydraulic system.
     
  6. Relieve all pressure from the hydraulic system; refer to the Service Manual for your machine.
    Danger
    Hydraulic fluid escaping under pressure can penetrate the skin and cause injury.
    • Ensure that all hydraulic fluid hoses and lines are in good condition and that all hydraulic connections and fittings are tight before applying pressure to the hydraulic system.
    • Keep your body and hands away from pinhole leaks or nozzles that eject high-pressure hydraulic fluid.
    • Use cardboard or paper to find hydraulic leaks.
    • Safely relieve all pressure in the hydraulic system before performing any work on the hydraulic system.
    • Get immediate medical help if fluid is injected into the skin.
     
  7. Remove the hood from the machine; refer to the Operator’s Manual for your machine.

Hydraulic hose (70 inches)
1
Hydraulic hose (129 inches)
2
Clamp
1
Clamp case
2
Bolt (5/16 x 2-3/4 inches)
