Bucket Up-Down : Troubleshooting

Step 1: Check the control box settings

1. Move the toggle switch to UP ⬆ and press the PWR button. The display shows up-40.

2. Use the UP/DOWN switch to go to CEN-06. Use the touchpad to change it to CEN-09.

3. Use the UP/DOWN switch again to go to TD-0.0. Change it to TD-1.0.

4. Press AUTO to save.

Step 2: Check the DCV (direction control valve)

Relief valve

1. Turn the relief valve fully anticlockwise (loosen it).

2. Use the UP/DOWN switch and watch the bucket.

– If the bucket moves: the relief valve is faulty. Replace it.

– If the bucket does not move: turn the relief valve clockwise slowly until the bucket moves up and down with the control box switch.

3. Turn the knob a little at a time until the bucket moves up and down smoothly.

Slow adapter

– A slow adapter slows down the oil flow. This makes the bucket move up and down slower and smoother.

Hose connections (P and T)

– Connect the P (pressure) hose to the P port of the DCV.

– Connect the T (tank) hose to the T port of the DCV.

Direct return

– The oil must flow straight back to the tank. This makes the bucket respond faster.

Step 3: Check the tractor

1. Check your tractor model and its hydraulic pressure settings.

2. Tractors above 60 HP usually have strong built-in hydraulic power.

Step 4: Try the laser transmitter

1. Press the Manual button on the laser transmitter. Check if the problem is fixed.

2. If it is not fixed, reset the laser: press the Windy and Expert buttons together for 3 seconds. Then wait 2–3 minutes.

Step 5: Set the receiver straight

3. Set the receiver at a 90° angle (straight up).

Step 6: Keep the tripod steady

1. Put weight on the tripod so that it does not move.

Step 7: Check the battery voltage

1. The tractor’s alternator sometimes sends unsteady voltage (above 14 V) to the battery.

2. The laser control box needs a steady 12 V. Unsteady voltage can cause the up/down problem.

3. To fix this, remove the alternator wire from the tractor.
