- Start the engine.
- Adjust the engine speed to position 6 by turning the engine speed dial.
- Lower the left console.
- Apply the swing lock pin.
Note: The implement lockout must not be activated.
- Swing left or right in order to release the swing brake.
- Check the pressure at pressure tap (2). The pressure should be equal to the pilot pressure.
- If the pressure at pressure tap (2) is not equal to the pilot pressure, check the pilot pressure on pressure tap (1) first.
- Release the swing joystick in order to activate the swing brake.
Note: The swing brake remains released for 3.5 seconds after the swing operation stops.
- Check the pressure at pressure tap (2). The pressure should decrease to 0 kPa (0 psi) at pressure tap (2) .
