Adjustment of the PPC Valve Clearances

Proper adjustment of the PPC valve (hand and foot) levers is crucial for maintaining system integrity. Follow these steps:

• Lower the equipment to the ground and turn off the engine.
• Switch the ignition key to ‘I’ and move the control levers to release hydraulic pressure. Then switch the key to ‘O’ (OFF) and remove it.
• Carefully loosen the oil-tank fill cap to relieve residual pressure.
• Remove the boot (1).
• Loosen the nut (2) securing the disc (3).
• Tighten the disc until it lightly contacts the four push-rods (4), ensuring no individual activation of push-rods during adjustment.
